Motorola 'Droid Maxx' image leaks out, could be extended battery version of Droid Ultra

Motorola 'Droid Maxx' image leaks out, could be extended battery version of Droid Ultra


Closing out a week full of Motorola leaks, @evleaks has posted this image of a device claimed to be the Droid Maxx, due on Verizon later this year and flashing a Kevlar frame with capacitive buttons. Earlier tweets and a source from Droid Life suggest this is the XT1080M, an extended battery version of the Droid Ultra (XT1080) that popped up on Motorola's website. An XT1080 recently appeared in the FCC database as well, spurring rumors we'll see more Droid-branded smartphones on the Big Red carrier very soon. To round out the rumors, the XT1030 is pegged as a Droid Mini, plus the XT1060 Moto X variant for Verizon. There's still no word on specs, but at this rate we'll probably have more info by tomorrow.

FAA approves Boeing 787 battery fix, gives the green light for repairs



It's been a few weeks since the Boeing 787 successfully completed testing, but the FAA has finally weighed in on the proposed tweaks to the plane's faulty lithium-ion batteries. Today the organization approved Boeing's battery fix, which means the aircraft maker could soon end the three-month grounding of all Dreamliners. The real action will come next week, when the FAA will issue instructions for making changes to the 787s and -- according to an official statement -- "publish in the Federal Register the final directive that will allow the 787 to return to service." Airlines operating the Dreamliner, including United and ANA, will be required to install containment and venting systems in addition to replacing the batteries with the new, modified components. This is certainly some good news for Boeing; these past few months haven't exactly been easy on the company's pocketbook (or reputation), but it still has plenty of work ahead in retrofitting its 50-strong fleet.

Tiny lithium-ion battery recharges 1000x faster than rival tech, could shrink mobile devices

Researchers devise 'most powerful' batteries in the world, shame supercapacitors


Supercapacitors are often hailed as the holy grail of power supplies, but a group of researchers at the University of Illinois have developed a lithium-ion microbattery that leaves that prized solution in the dust, recharging 1,000 times faster than competing tech. Previous work done by Professor William P. King, who led the current effort, resulted in a fast-charging cathode with a 3D microstructure, and now the team has achieved a breakthrough by pairing it with an anode devised in a similar fashion.


The resulting battery is said to be the most powerful in the world, avoiding the usual trade-off between longevity and power while having a footprint of just a few millimeters. By altering its composition, scientists can even optimize the contraption for more juice or increased life. It's expected that the technology could make devices 30 times smaller and help broadcast radio signals up to 30 times farther, but it'll still be a while before it winds up in a super-slim phone within your pocket. For now, the researchers have their sights set on integrating the tech with other electronic components and investigating low-cost manufacturing.

Google Glass support page lists tech specs for camera, battery, audio and display



The trickle of Google Glass details (they're shipping, the API is available and an Android companion app is live) has suddenly turned into a flood tonight, as 9to5Google points out a support page listing the device's technical specs. While we knew some bits about its capabilities (some of which were explained in a patent application), the official list reveals its display will be equivalent to a 25-inch HD screen viewed from eight feet away, while it's camera does 5MP stills and 720p video. It packs 16GB of storage onboard, 12GB of which are available to the wearer. Audio is transferred via a bone conduction transducer, while its wireless capabilities include Bluetooth and WiFi 802.11 b/g. There's a micro-USB charger included with it and the battery is expected to last a "full day of typical use" although video and Google Hangouts will drain it more quickly. Also published is an FAQ for things like "Is it ok to go scuba diving with Glass?" (A: No, jackhammering is also probably out, while laws concerning mobile devices and driving may rule out use behind the wheel as well), covering things any Explorers should know before their headset arrives.

New Nissan Leaf comes to the UK with battery leasing option, extended range

NEW NISSAN LEAF: MORE AFFORDABLE, MORE FLEXIBLE

New British-built version boasts over 100 improvementsThree trim levels offer buyers plenty of choiceBattery leasing available for the first timeEnhanced battery warranty gives added peace of mind

The next generation of Nissan's all-electric LEAF has arrived – and for the first time, buyers can lease batteries for the 100% electric car and choose one of three trim levels.

A new pricing structure has been introduced to reflect the three trim levels and the battery-leasing options now available – but things are far from complicated. Cars bought with leased batteries will be known as 'Flex' models and buyers will be able to get behind the wheel of an entry-level Visia LEAF .

The new LEAF features more than 100 improvements over its predecessor – many of which were made as a result of feedback from Nissan's active community of LEAF owners.

Most notably, the car's range has been extended from 109 miles to 124 miles. And its battery is capable of recharging in about half the time of the first-generation LEAF.

The longer range has been achieved by improving the LEAF's aerodynamics and its regenerative braking system and a more efficient E-powertrain. The real world range has also been improved with the introduction of a new heating system which is 70 per cent more efficient through the use of a heat pump in the system.

But that's far from the whole story. New interior trim, the addition of Nissan's Around View Monitor technology and new suspension settings specifically tailored for European roads build on the LEAF's unique driving experience.

The three trim levels available to buyers are Visia, Acenta and Tekna. All models have increased boot space because of the relocation of the charging point and an enhanced interior trim. There is a height adjust facility on both front seats and more foot space for passengers.

At the top of the range, Tekna features a BOSE™ energy-efficient sound system with a subwoofer and seven speakers. In addition, there are 17-inch alloys and LED headlamps.

Whichever route buyers choose to LEAF ownership, peace of mind is assured with Nissan's enhanced battery warranty. The warranty on the previous-generation LEAF's battery covered it against defective materials or workmanship for five years. The extended warranty also protects against capacity loss, with a commitment to repair or replace a battery which falls short of what might reasonably be expected***.

Nissan's announcement of a new era for emission-free motoring continues to drive the electric revolution forward. Owning an electric car has never been more appealing. Some of the benefits are well-known, such as the lack of Vehicle Excise Duty and exemption from the London congestion charge, but it's becoming easier to charge up a Nissan LEAF on the move with more public charging points opening all the time. And of course, the cost of a full battery charge is a fraction of the price of a tank of petrol.

Jim Wright, Managing Director of Nissan Motor (GB) Ltd, said: "We are very proud of the new Nissan LEAF, which underlines our commitment to the future of electric motoring.

"With more than 100 improvements over the outgoing model, it really does mark the next stage in the electric motoring revolution. Built at our record-breaking Sunderland plant for British drivers using British roads, we're looking forward to it becoming our next home-grown success story."

Tesla Model S axes 40 kWh battery option, surpasses sales goals

Tesla Model S Sales Exceed Target

Profitability Guidance Amended Upward; 40 kWh Battery Cancelled

Sunday, March 31, 2013

Tesla Motors announced today that sales of its Model S vehicle exceeded the target provided in the mid-February shareholder letter. As customers who note their Model S serial number this weekend will realize, vehicle deliveries (sales) exceeded 4,750 units vs. the 4,500 unit prior outlook. As a result, Tesla is amending its Q1 guidance to full profitability, both GAAP and non-GAAP.

"I am incredibly proud of the Tesla team for their outstanding work. There have been many car startups over the past several decades, but profitability is what makes a company real. Tesla is here to stay and keep fighting for the electric car revolution," said Elon Musk, Tesla Motors co-founder and CEO. "I would also like to thank our customers for their passionate support of the company and the car. Without them, we would not be here."

Also being announced today is that the small battery option for the Model S will not enter production, due to lack of demand. Only four percent of customers chose the 40 kWh battery pack, which is not enough to justify production of that version. Customers are voting with their wallet that they want a car that gives them the freedom to travel long distances when needed.

The customers who ordered this option will instead receive the 60 kWh pack, but range will be software limited to 40 kWh. It will still have the improved acceleration and top speed of the bigger pack, so will be a better product than originally ordered, and can be upgraded to the range of the 60 kWh upon request by the original or a future owner.

Tesla is also revealing a small Easter egg today: all 60 kWh cars have been and will be built with Supercharger hardware included. Tesla is taking a slight cost risk that ultimately all customers will want to buy the Supercharger upgrade and receive unlimited, free long distance travel for life. Even for those that never drive long distances, this will improve the resale value of their car to people that do.

Dell Latitude 10 review: a business-friendly Windows tablet with great battery life

Dell Latitude 10 review: a business-friendly Windows tablet with great battery life

More Info Dell's Latitude 10 tablet and dock, OptiPlex 9010 AIO, Latitude 6430u laptop arrive to tempt business pros Dell's Latitude 10 tablet, OptiPlex 9010 all-in-one and Latitude 6430u Ultrabook all available now Dell intros Latitude 10 enhanced security for all your governmental tableting needs

We've been making the grand tour of Windows 8 hybrids running low-powered Atom processors, and our latest stop is Dell's Latitude 10. While some similar systems, such as the ASUS VivoTab Smart and the Lenovo ThinkPad Tablet 2, focus on portable designs and long battery life, the Latitude 10 takes after that group of devices with "Smart" and "Pro" in their name.


Indeed, like the Surface Pro and Samsung ATIV Smart PC Pro, the Latitude 10 flaunts a large variety of corporate-friendly features, such as TPM, a productivity dock, a Wacom-certified stylus and a Bluetooth keyboard. The entry-level configuration will set you back a tolerable $499, but adding on business essentials such as the dock and keyboard could soon have you looking at a price above the $1,000 threshold. Does the Latitude 10 work well enough to warrant the dough -- and satisfy on-the-go professionals? You know where to look if you want to find out. Dell Latitude 10 reviewSee all photoswhen.eng("eng.galleries.init")

Look and feel
DNP Dell Latitude 10 review an Atompowered hybrid with great battery life


"Inoffensive" is the word we'd use to describe the Latitude 10's design -- and we imagine that's exactly what many corporate customers will want. Though we have no qualms with the straightforward, black-rectangle aesthetic, we do take issue with the extremely wide bezel surrounding the 1,366 x 768 display. This cheapens the device's feel, and it makes the 10.1-inch panel seem smaller.


"Inoffensive" is the word we'd use to describe the Latitude 10's design -- and we imagine that's exactly what many corporate customers will want.
At 1.45 pounds and 0.4 inch thick with a 30Wh battery, this isn't anywhere near the wispiest 10.1-incher around, but it does feel plenty sturdy in the hand. This is thanks to a reinforced magnesium-alloy frame, and the coating of Gorilla Glass doesn't hurt either. The back sports a soft-touch finish that makes for a comfortable grip -- you shouldn't have to put this tablet's solid build to the test with any accidental drops.

By and large, button and port placement makes perfect sense on the Latitude 10 -- and there is no shortage of connections on board. The physical Windows 8 Start button sits in its typical spot underneath the screen. Oddly, though, the button is slightly recessed rather than raised, and as a result it's a bit tricky to press. We had to apply more pressure than we're used to, and it was especially difficult to register a press when the tablet was angled upright in the bundled dock. The only other feature you'll notice on the front is the 2-megapixel, front-facing camera.


The top edge of the Latitude 10 is home to a full-size SD card slot, the power button and a toggle for auto-rotate. The Enhanced Security model, which we got a chance to play with, includes a smart card reader along the top. The combo headphone / mic jack, USB 2.0 port and mini-HDMI connection sit on the right edge, while you'll find the volume rocker and Kensington lock slot on the left. Finally, the power connector and a micro-USB port line the bottom side. Turn the device over, and you'll find plenty going on. In addition to the 8MP rear shooter with LED flash, the Dell logo and two small sets of speakers, the swappable 30Wh battery sits prominently on the backside, with a slide lock allowing for its removal. (A larger 60Wh battery was included with our review unit -- more on that later.)


Our unit offers 3G connectivity, and the micro-SIM slot is located under the removable power pack. The battery takes up a good half of the surface, and while this interrupts the otherwise clean lines, the promise of longer battery life trumps any superficial design concerns. We had to wiggle both the two- and four-cell batteries loose when switching them out, as the latch system got stuck halfway when we tried to move it.

Etc.
DNP Dell Latitude 10 review an Atompowered hybrid with great battery life


The variety of configuration options for the Latitude 10 verges on confusing. Not only are there Essential, Standard and Enhanced Security models, but there are a slew of optional accessories as well. We checked out a Latitude 10 bundled with the productivity dock, a $100 add-on. This 1.8-pound peripheral adds to an already impressive number of ports, with four USB 2.0 connections, a headphone jack and a full-size HDMI for hooking up an external monitor. There's also a power connector for charging the tablet while it's docked.


It was easy to attach the Latitude 10 to the stand, but it felt rather wobbly; lifting up on the slate detached it from the base -- and that was without applying much pressure. We imagine the dock won't move far from users' desks, though, and it offers a comfortable -- though non-adjustable -- viewing angle for both watching movies and composing emails and documents. Other accessories include a Bluetooth keyboard and mouse combo (ranging from $40 to $86, depending on which of the three bundles options you choose) and a $40 soft-touch case that can act as a stand. Our review unit also came with the $40 Dell KM632 keyboard and mouse package, along with the case.


Speaking of the Bluetooth keyboard and mouse, we had to force ourselves to use the device in tablet mode after enjoying this setup. You'll definitely want a set of hardware keys if you plan to do any real work, and both the chiclets and the mouse were responsive and comfortable for navigating Windows 8. That said, the Bluetooth keyboard is desktop-size, meaning the slate's 10.1-inch screen feels small in comparison. One other nitpick: the top of the mouse is removable, allowing you to insert the two AA batteries, and it comes off far too easily. We had to reattach it on several occasions during our hands-on time. Dell doesn't offer its own keyboard case; rather, it sells the Kensington KeyFolio Expert through its website.

Display, pen input and sound
DNP Dell Latitude 10 review an Atompowered hybrid with great battery life


The Latitude 10's 10.1-inch screen sports a 1,366 x 768 resolution, which is par for the course when it comes to Atom-based tablets. More impressive than the pixel count is the 450-nit brightness rating; images really pop on this panel. When we watched Netflix, played a few games and surfed the web, all content appeared crisp, and colors looked accurate. Like the screens on the ASUS VivoTab Smart and the Lenovo ThinkPad Tablet 2, this display uses IPS technology, so you can expect wide viewing angles. We had no trouble making out a video from both the far left and right. Visibility would be even better if the display didn't have such a glossy finish, but that should only be an issue in settings with bright overhead lighting.


An active Wacom digitizer is available for about $34, and it's only compatible with the higher-end configurations of the Latitude 10. (The lower-end Essentials version will only work with a passive stylus.) We used the pen in programs such as Windows Journal, which includes handwriting recognition, and Paint. The stylus itself feels cheaply made; it doesn't provide as good of a grip as Samsung's S Pen, for instance. Still, it works well for selecting small objects on screen, and the capacitive display offers very good palm rejection. Only once or twice did the panel detect accidental input when we were writing with the digitizer. The Latitude 10 itself doesn't have a built-in slot for storing Wacom's device, but the soft-touch case that came with our review unit sports a penholder.


Audio doesn't get very loud on the Latitude 10. The two small stereo speakers are located on the back of the device, which means music and dialogue come through muffled when the tablet is on your desk (or your lap). Songs streamed via the Slacker app don't pack much punch at all, though -- as we always say with slates -- donning a pair of headphones allows for louder, slightly richer sound.

As we mentioned in our review of the ASUS VivoTab Smart, lower-powered Windows tablets are pretty much uniform when it comes to specs. Like that product and literally every other competing model we've tested, the Latitude 10 runs an Intel Atom Z2760 processor clocked at 1.8GHz, with 2GB of RAM and the Intel Graphics Media Accelerator. It's no surprise, then, that Dell's slate turns in virtually identical benchmark scores to its competitors. In ATTO, the Latitude 10 notched max read and write speeds of 82 MB/s and 35 MB/s, respectively, and a cold boot takes about 15 seconds.


Unsurprisingly for an Atom-powered device, the Latitude 10 wasn't able to run the 3DMark 11 graphics benchmark, which requires DirectX 11 support. That's a good indicator of what kind of gaming performance to expect -- you'll be fine playing Angry Birds, Solitaire and the like, but serious titles are out of the question. We experienced a few glitches, such as app crashes and force quits throughout our hands-on time with the Latitude 10, but these moments were few and far between. Switching between apps didn't cause the system to stutter, and we never found ourselves tapping our fingers waiting for programs to load.


When we ran our battery test, which involves running a locally stored video on loop with WiFi on and brightness set to 65 percent, the Latitude's 30Wh battery lasted nine hours and three minutes. That compares favorably to other Atom-powered machines, such as the Acer Iconia W510 (8 hours and 19 minutes) and the HP Envy x2 (7 hours and 53 minutes). While that's fairly average for an Atom-powered Windows 8 tablet, it trumps them all when you add in the optional 60Wh power pack: with that attached, we got a jaw-dropping 16 hours of runtime.

The Latitude 10 sports a 2-megapixel, 720p, front-facing camera for video chats along with a 8MP rear shooter with flash. When we took a few selfies in our brightly lit office, our images appeared grainy with a strong yellowish overcast. This is sadly the status quo for most tablet webcams, but moving to an area with natural light should help if you have to take a Skype meeting in a pinch. Dell Latitude 10 sample shotsSee all photoswhen.eng("eng.galleries.init")


Our samples from the 8MP rear camera show fairly accurate colors and for the most part look quite sharp. Some pictures taken in shadowy settings look darker than they should, and images taken with flash unsurprisingly look very washed out. Camera options are fairly limited: there are controls for brightness and contrast, along with a toggle for auto or manual exposure. Sample video footage of Union Square in New York looked crisp and didn't exhibit much jerkiness. In short: if you insist on bringing a tablet along to document your adventures, the Latitude 10's cameras will certainly suffice.

Software and warranty
Dell bolsters the Latitude 10's cred as a business device with several security-minded features, including TPM and support for Computrace. Keep in mind that this software isn't available on the Essentials version of the device. The company also offers data encryption for protecting files.

We've seen more offensive pre-loads than the software selection on the Latitude 10. Out of the box, the tablet includes Dell Backup and Recover, a trial of Microsoft Office and Skype. You'll also find the standard Windows 8 apps, such as Bing, Maps and Weather. Our 3G-equipped configuration of the Latitude 10 also comes with the AT&T AllAccess utility for managing your data plan. Dell offers a standard one-year limited hardware warranty.

Configuration options and the competition
There are several available configurations of the Latitude 10, all with the same 1.8GHz Intel Z2760 processor and 2GB of RAM. On the lower end is the $499 so-called Essentials configuration, which runs Windows 8 and offers a 32GB SSD. For $80 more ($579 total), you can step up to a 64GB Essentials model. Next up the rung is the $649 Latitude 10, which gets you Windows 8 Pro, a 64GB SSD, a swappable battery, active stylus support and security features such as TPM. A $779, 64GB model includes those same features and adds a smart card reader and fingerprint reader, and it also supports mobile broadband. You could also spring for Dell's $849 Mobility bundle, which includes the productivity dock and 3G connectivity.
Some of the most useful features don't feel tailor-made for a portable lifestyle, and how useful are peripherals if they can't travel anywhere with you?

We took a look at two configurations of the Latitude 10. First up was the Mobility bundle, which Dell supplemented with several add-ons. With the four-cell swappable battery, Bluetooth keyboard and mouse, soft-touch case and Wacom digitizer, that option comes out to $1,019. (Note that Dell often runs promotions, so you may see slightly different prices.) Due to a faulty battery, though, Dell sent us another model to test: the Enhanced Security version with a fingerprint reader, smart card reader, swappable four-cell battery and the productivity dock. That configuration -- without peripherals such as the Bluetooth keyboard and mouse -- costs about $934. If you're going to go for the Latitude 10, we'd recommend shelling out for the full trappings, since you'll need a keyboard -- and likely an external monitor -- to get real work done. That said, those extras bring the price into Ultrabook territory, and you won't be getting Core i5-level performance with Dell's hybrid machine.


As always, we recommend surveying the field before committing to a product, and you have quite a few other options if the Latitude 10 piques your interest. When it comes to a good value, it's hard to beat the ASUS VivoTab Smart, which gets you 64GB of storage for $499. We like the 1.28-pound tablet's design -- with a polycarbonate back shell -- and relatively high-performing camera, but battery life isn't best in class, and there's no pen support. Acer's $550 Iconia W510 is another relatively inexpensive offering, and it has good battery performance and an IPS display in its favor. The downside is a cramped and unattractive keyboard dock -- and that brings the price up to $750.


If you want to wield a stylus, check out the Lenovo ThinkPad Tablet 2. This may just be our favorite low-powered Windows 8 hybrid, thanks to a comfortable keyboard and impressive longevity. Pen input does come at a slight premium, though: it's $649 for a 64GB, stylus-equipped model. Lenovo also has the more consumer-friendly IdeaTab Lynx (review coming soon). There's also the Samsung ATIV Smart PC Pro, which runs a full-fledged Core i5 CPU and includes an S Pen, but that will set you back $1,200.

Wrap-up
DNP Dell Latitude 10 review an Atompowered hybrid with great battery life


There are plenty of things to like about the Dell Latitude 10, in no small part due to the vast number of optional accessories that boost the device's productivity chops. Even without the swappable four-cell battery, this machine offers good longevity, and its bright IPS display stands out among other panels in its class.


That's not to say this product is without its flaws, though; some of the most useful features, such as the productivity dock and the optional keyboard, don't feel tailor-made for a portable lifestyle, and how useful are peripherals if they can't travel anywhere with you? The price is also pretty steep when you factor in all the extras that make this system so corporate-friendly. If your pockets can handle it, splashing out for the highest-end configuration with all the bells and whistles will net you a solid product. Those who need to stay south of $1,000, though, should consider the ThinkPad Tablet 2 and ASUS VivoTab Smart instead.


Update: The Dell Latitude 10 runs Intel's Graphics Media Accelerator, not Intel HD Graphics 4000.

FAA approves 787 Dreamliner certification plan for testing Boeing's battery fix



The last we heard in the saga of the grounded 787 Dreamliner came last month, when Boeing announced that it had developed a "permanent" fix to the airliner's battery fire issues. Today, the FAA issued its approval of the company's certification plan, allowing Boeing to begin testing its proposed battery improvements. Boeing's fix includes redesigned internal batteries, better insulation and new venting system, and the FAA has given the go-ahead for testing prototype versions of the setup on two aircraft. The agency originally cleared Boeing for limited testing and ferrying of 787s last month, but completing the FAA certification program is key for the company returning to commercial service. Don't get set on a first-class ticket to Japan just yet, though; these things take time.

Stretchable, serpentine lithium-ion battery works at three times its usual size

Stretchable, serpentine lithiumion battery works at three times its size


While we've seen more than a few flexible batteries in our day, they're not usually that great at withstanding tugs and pulls. A team-up between Northwestern University and the University of Illinois could give lithium-ion batteries that extreme elasticity with few of the drawbacks you'd expect. To make a stretchable battery that still maintains a typical density, researchers built electrode interconnects from serpentine metal wires that have even more wavy wires inside; the wires don't require much space in normal use, but will unfurl in an ordered sequence as they're pulled to their limits. The result is a prototype battery that can expand to three times its normal size, but can still last for eight to nine hours. It could also charge wirelessly, and thus would be wearable under the skin as well as over -- imagine fully powered implants where an external battery is impractical or unsightly. There's no word yet on whether there will be refined versions coming to real-world products, but we hope any developments arrive quickly enough to give stretchable electronics a viable power source.

USC battery wields silicon nanowires to hold triple the energy, charge in 10 minutes

USC battery wields silicon nanowires to hold triple the energy, charge in 10 minutes


There's no shortage of attempts to build a better battery, usually with a few caveats. USC may have ticked all the right checkboxes with its latest discovery, however. Its use of porous, flexible silicon nanowires for the anodes in a lithium-ion battery delivers the high capacity, fast recharging and low costs that come with silicon, but without the fragility of earlier attempts relying on simpler silicon plates. In practice, the battery could deliver the best of all worlds. Triple the capacity of today's batteries? Full recharges in 10 minutes? More than 2,000 charging cycles? Check. It all sounds a bit fantastical, but USC does see real-world use on the horizon. Researchers estimate that there should be products with silicon-equipped lithium-ion packs inside of two to three years, which isn't long to wait if the invention saves us from constantly hunting for the nearest wall outlet.

Android 4.2.2 spreads to Nexus 4 with new battery sounds (update: no LTE)

Android 422 spreads to Nexus 4 owners with new battery sounds


No, Nexus 4 users, Google hasn't forgotten about you. About a day after Google started pushing Android 4.2.2 to most Nexus devices, the company's latest and greatest smartphone is also getting the patch over the air. When it shows, there will be a pair of small additional rewards for running the latest hardware -- the Nexus 4 now plays a unique sound when wireless charging kicks in, as well as an updated low-battery sound. We wouldn't upgrade just to get the new tones, but they cap what's proving to be a more significant update than the version number would suggest.


Update: As Brian Klug over at AnandTech notes, Google both giveth and taketh away -- that very, very unofficial LTE access disappears with the update. When 4G only worked in limited areas, and was never going to get official support, we won't cry too much.

WSJ: Boeing readying battery tweaks for 787 Dreamliners

WSJ: Boeing readying battery tweaks for 787 Dreamliners


The Wall Street Journal has gotten word that Boeing is preparing tweaks to its 787's lithium-ion batteries that could minimize the risk of fire and let its Dreamliners take to the skies before a long-term solution is sussed out. Citing industry and government officials, the WSJ says the modifications will see a larger separation between battery cells in an effort to lessen the risk of heat and fire spreading. Other measures may include keeping cells more firmly in place to prevent them from moving about and interfering with electronics, incorporating heat sensors and a beefed-up battery cover that could contain flames and chemicals. Changes to the aircraft aren't nailed down across the board just yet, and they still need approval by Japanese and American regulators before they can be applied. According to one of the WSJ's sources, a best-case scenario could see Dreamliners put back on passenger flight duty in March.

HP Spectre XT TouchSmart review: all that, minus the battery life

HP Envy Spectre XT TouchSmart review all that minus the battery life

We had plenty of nice things to say about the HP Envy Spectre XT when we reviewed it last year, but we were already looking ahead to the HP Spectre XT TouchSmart, which steps up to a 1080p touchscreen. Well, here it is, and with 10-point touch and the same all-metal design as its predecessor, this 15-incher looks mighty promising. But is it worth $1,350 -- or more, if you want an SSD? Head past the break to find out. HP Spectre XT TouchSmart reviewSee all photoswhen.eng("eng.galleries.init")
Look and feel
DNP HP Envy Spectre XT TouchSmart review all that minus the battery life

The TouchSmart will look quite familiar to those who have seen the Envy Spectre XT. It sports the same elegant, all-metal chassis and brushed-silver finish, along with a reflective HP logo on the lid. The only real difference -- apart from the TouchSmart's significantly larger footprint -- is that the Beats Audio and Spectre XT TouchSmart branding sit on the top of the display, as opposed to below the screen on the 13-inch XT. All in all, it's an attractive package, though it's also one that draws constant comparisons to Cupertino's baby.

At 4.96 pounds and 0.87 inch thick, this machine is hardly the wispiest incarnation of an Ultrabook, but it's far from bulky for a 15-inch machine. Still, you will
notice its weight when toting it in your backpack or briefcase; we're not sure you'd want to carry it to work every day. Like its non-touch sibling, this notebook feels very comfortable in the hand thanks to grippable, rounded corners and a lovely soft-touch finish on the bottom. The design feels very sturdy as well; it never creaked or bent under pressure throughout our hands-on time.
Everything is in its logical place on the TouchSmart, with the speaker grille and power button sitting at the top of the keyboard deck, and the HP TrueVision HD Webcam centered above the display. The laptop's bottom is completely clean save for an air vent and two speakers; there's no removable battery here. Along the sides, you'll find a generous selection of ports. An SD card slot, 3.5mm headphone jack, USB 2.0 port, charging connector and a Kensington lock slot sit on the right side, while an Ethernet jack, full-size HDMI port, Thunderbolt and two USB 3.0 connections line the left edge. Incidentally, this is the first HP system to include a Thunderbolt port.
Keyboard and touchpad
DNP HP Envy Spectre XT TouchSmart review all that minus the battery life

We were big fans of the Envy Spectre XT's keyboard, and the 15-inch TouchSmart's backlit layout is equally comfortable. It took a bit of time for this reviewer's smallish hands to adjust to the spacious setup, but the keys themselves offer a satisfying amount of travel. You should have no trouble getting up to your usual words-per-minute pace.

The large keyboard deck provides ample space for resting your palms and wrists, and it also accommodates a sizable Synaptics touchpad. The clicker executes Windows 8 gestures flawlessly, and it offers just enough resistance for scrolling to be fluid but not overzealous. The integrated left- and right-click buttons are responsive and quite good at distinguishing accidental input from intentional taps. As we've seen on previous HP systems, this machine offers a trackpad-disabling feature, which is activated with a double tap on the clicker's upper-left corner.
Display and sound
DNP HP Envy Spectre XT TouchSmart review all that minus the battery life

With a 1080p resolution and IPS technology, the TouchSmart's 15.6-inch Radiance display provides bright, crisp visuals. It's one of the best panels we've seen on an Ultrabook lately -- on par with Acer's and ASUS' latest offerings -- and it's one of the advantages this system has over the non-touch Envy Spectre XT, which sports a 1,366 x 768 screen. HP wouldn't confirm whether this is the same 1080p panel that had color calibration issues on the Envy 15, but a spokeswoman said TouchSmart users shouldn't experience that problem. (We didn't during our hands-on time.)


This is one of the best panels we've seen on an Ultrabook lately.

Colors look rich and accurate, and content is visible from even extreme off-angles. The touchscreen is very responsive to all the Windows 8 gestures you'll be throwing at it. Scrolling, swiping to bring up the Charms bar and pinching to zoom all work without a hitch. Even though we're fans of this laptop's touchpad, we often preferred navigating via the touch display -- its large screen almost begs to be touched.

Unsurprisingly, the TouchSmart packs Beats Audio, and sound pumped through the machine's tilted speaker grille is plenty loud, if not particularly rich. As is usual with Beats, we didn't detect as much tinniness as we have on other laptops, but bass is still limited. Listening to music and watching movies with headphones is definitely a more immersive, sonically pleasing experience, but it's good to know you have enough volume should you want to blast some tunes in the open air.
Performance and battery life

Our review unit is configured with a 1.9GHz Core i7-3517U processor with 8GB of RAM, Intel HD Graphics 4000 and a 500GB hard drive spinning at 5,400 RPM. The Ultrabook performed respectably on synthetic benchmark tests, such as PCMark7. When it comes to I/O performance, though, this laptop falls far behind the SSD-equipped competition -- we're talking max reads and writes of 130 and 72 MB/s, respectively, while we regularly see Ultrabooks turn in reads and writes north of 500 MB/s. If you've been impressed up until this point, don't despair: there's an SSD configuration available (more on that later), and we imagine it will offer significantly better performance.

In everyday use, the TouchSmart ran smoothly, though occasionally we noticed a few-second delay in the touchscreen's responsiveness after waking from sleep. Still, cold-booting into Windows 8 takes 12 seconds, which is on par with most Win 8 machines we've tested, and the laptop was never sluggish in switching between apps and launching programs. When we fired up a demo on Steam, the fan started whirring almost instantly. Not that the sound was incredibly loud, mind you, but the laptop's bottom felt very warm, and it took the system several minutes to pipe down after we had closed the game.


HP could have used a bigger battery to increase runtime.

When we ran our battery test, which entails playing a locally stored video on loop with WiFi on and brightness set to 65 percent, the TouchSmart's four-cell battery lasted four hours flat. We don't expect stellar longevity from larger notebooks -- especially those with touchscreens -- but the TouchSmart still falls short of our expectations. Even the much thinner 13-inch Acer Aspire S7 lasted four hours and 18 minutes; there's no reason that HP couldn't have used a bigger battery to increase runtime.

HP's pre-load definitely makes its presence known, as Norton Internet Security pop-ups will greet you upon that first boot-up -- you can either disable them or activate the complimentary two-year subscription. Other pre-installed programs include full versions of Adobe Photoshop Elements 10 and Premiere Elements 10 (signature amenities in the Spectre line) and proprietary software such as HP Support Assistant, Connected Music and Connected Photo. You'll find the standard shortcuts to the Kindle store and Netflix here, too. The Spectre XT TouchSmart comes with a two-year warranty, which is fairly generous considering that most notebooks come with just one year of protection.
Configuration options and the competition
DNP HP Envy Spectre XT TouchSmart review all that minus the battery life

We reviewed the $1,350 configuration of the HP Spectre XT TouchSmart, which includes a 1.9GHz Core i7 CPU, 8GB of RAM, Intel HD Graphics 4000 and a 500GB (5,400RPM) hard drive. The entry-level model goes for $1,275, and the only difference is that it packs 4GB rather than 8GB of RAM. For $1,520, you can upgrade to a 128GB SSD with 8GB of RAM, and $1,720 nets you a 256GB SSD with 8GB of RAM. As you can see, things get pricey when you factor in the speedier storage option, and you'll find many similar alternatives that undercut the TouchSmart's price by several Benjamins. A few of them below:

Among machines in the TouchSmart's size category, the $1,100 Dell Inspiron 15z is worth a once-over. It also offers a Core i7 processor, 8GB of RAM and a 500GB hard drive, but rather than integrated graphics it packs NVIDIA's GeForce GT 630M chip. It's a hair lighter than the TouchSmart, at 4.78 pounds, but it still manages to fit a DVD drive. It does offer a touch display, but with just a 1,366 x 768 resolution. If you don't need a touchscreen, we'd suggest the 15-inch Samsung Series 9, which delivers long battery life in a remarkably slim design. A model with a 128GB SSD, 8GB of RAM and a Core i5 CPU will set you back $1,399. And if screen size is negotiable, we recommend the ASUS UX31A Touch. The Core i7 configuration we recently reviewed is not yet available, but its fluid user experience and bright touchscreen earned our thumbs-up.

If you're game to hold out for a few more months, you could consider the Sony VAIO T15. Pricing and specs are still to come, but we found the laptop attractive and responsive when we went hands-on at CES. The new Samsung Series 7 Chronos could also be worth the wait if you aren't on a tight budget. The laptop will feature AMD's new Radeon HD 8870M GPU and a Core i7 CPU -- and it promises 11 hours of battery life. We got a taste of the product at CES, but Sammy has yet to mention pricing and availability. Finally, if short battery life doesn't dissuade you, the Acer Aspire S7 has a lot going for it. Its 1080p display rivals the TouchSmart's, and it delivered impressive scores when we benchmarked it.

Overall, HP did a great job with the Spectre XT TouchSmart, releasing a notebook with a sleek, comfortable design and a top-notch touch display. While we want to give this Ultrabook high marks, we can't overlook that the poor battery life and high price could be dealbreakers for some. If you can live with those compromises and your pockets are deep enough, by all means splurge. Otherwise, you have a host of other compelling options to choose from -- and there will only be more in the months to come.

Panasonic's Any Battery Light isn't picky about battery size, takes anything in your junk drawer

Panasonic's Any Battery Light isn't picky about battery size, takes anything in your junk drawer


Battery nerds rejoice: Panasonic has cobbled together an electronic torch that will play nice with almost anything in your collection. The Any Battery Light can siphon power from AA, AAA, D and C-sized batteries, lighting the dark with just a single serving of any compatible size. Loading it up with all four provides up to 86 hours of continuous LED illumination. Not all batteries are equal, of course -- a single AAA isn't going to shine as brightly as its thicker cousins, and users will need to manually flip a switch to choose what size battery the torch draws its light from. Japanese consumers will be able to pick one up for about ¥2,000 ( $23) in red or white later this month.

Samsung's Galaxy S3 extended battery to become available Jan. 5, in Germany at least

Android Central

Before the holidays, an OEM extended battery kit surfaced for the Samsung Galaxy S3, initially going on pre-order at a British retailer. While that same retailer is still taking pre-orders for the item without an expected shipping date, Amazon Germany has gone one better. 

According to the item's listing on Amazon.de, the Samsung Extended Battery Kit will become available on January 5. Pricing is relatively consistent with earlier reports, coming in at €39.90, slightly cheaper even than the expected RRP of £40 (€48) in the UK. There is no word yet on if/when we can expect to see wider availability of this. 

Additionally, click on past the break for a quick video -- in Slovenian, and you'll want to spin on to about 1:05 -- which demonstrates the extended battery and replacement battery door. The best news? It doesn't seem to add much additional thickness to the phone.

Nokia Windows RT tablet to feature keyboard cover with battery power?

Nokia Windows RT tablet to feature keyboard cover with battery power?Will Nokia's first tablet arrive at MWC?

Nokia will launch a Windows RT tablet in early 2013, according to reports on Christmas Eve.

The Verge's sources have claimed that the long-rumoured slate will, like the Microsoft Surface tablet, boast a 10.1-inch display along with USB and HDMI connectivity.

The report also revealed that Nokia will aim to stand out from the ground with an innovative keyboard cover that, according to the source, will "envelop the tablet like a book."

The keyboard cover, which is said to clip onto the tablet and act as a kickstand, could also feature a battery pack to give the tablet a boost when power is low and two USB ports for extra connectivity.

Beyond the purported case, the report claims that Nokia's device will also have a ten hour battery with fast charging tech that will return the tablet to a 50 per cent charge in a short space of time.

With Windows RT on-board, that means an ARM chipset. However, sources have claimed that Nokia will be producing a limited run of its first tablet, with a view to launching a Windows 8 version also.

Nokia has refused to comment on the report, which also claims the device will launch at Mobile World Congress in Barcelona in February.

TOKYO | Wed Nov 28, 2012 2:12am EST

TOKYO (Reuters) - Sony Corp has been approached by at least three investment banks offering to sell its battery business as the struggling Japanese group looks to offload non-core assets and focus on reviving its consumer electronics business, banking sources said.

Selling the unit, which employs 2,700 people and had sales last year of $1.74 billion, would help Sony cut costs and generate cash as it restructures its operations, three people involved in the preliminary discussions told Reuters.

The company, a byword for innovative gadgetry in the 1970s and 80s, has been battered by weak demand for its TVs in a fiercely competitive market. The TV business has racked up huge losses; Sony's market value has slumped to below $10 billion and ratings agency Fitch last week downgraded the company's debt to "junk" status - a move likely to push up borrowing costs and make asset sales more attractive.

CEO Kazuo Hirai has pledged to rebuild Sony around gaming, digital imaging and mobile devices, while nurturing new businesses such as medical devices. He is axing 10,000 jobs, closing facilities and selling assets. Any disposals would be part of a broader "garage sale" by Japan's leading electronics groups that are hurting in weak markets and tight financing.

Potential buyers for Sony Energy Devices Corp - founded in 1975 as Sony-Eveready, a joint venture with Union Carbide Corp - could include Taiwan's Hon Hai Precision Industry and BYD Co Ltd, a Chinese carmaker backed by billionaire investor Warren Buffett, said one of the sources. Hon Hai is also in negotiations to become rival TV maker Sharp Corp's biggest shareholder.

FOREIGN INTEREST

Despite a strong yen, interest is likely to come mainly from potential foreign buyers, said the sources, who did not want to be named as the talks are private.

Selling the business overseas may not go down well with a Japanese government that in the past has kept technology at home by promoting alliances between local producers. Panasonic Corp, NEC Corp and Hitachi Ltd also make lithium-ion batteries, though the firms' fabrication technology differs.

Sony declined to comment on the possible sale of the business, which makes lithium-ion batteries used in smartphones, tablets and PCs. "At our corporate strategy announcement in April, (Hirai) said we would explore possible alliances in E-vehicle batteries and battery storage," said spokesman George Boyd.

As with TVs, Sony has struggled to compete against South Korean rivals in a battery business that is worth $18 billion a year. The small cells that power mobile devices now account for around 60 percent of the market, ahead of those used in cars and electrical tools, according to research company IHS iSuppli.

While lithium-ion battery demand has steadily expanded with the boom in mobile consumer electronics, severe price competition has resulted in razor thin margins that favor large-scale manufacturers with weak local currencies.

"The battery business is a prime example of the company's loss-making and unwanted assets. It doesn't make sense for them to keep it," said one of the banking sources.

FALLING MARKET SHARE

As Hirai doubles down on Sony's strength in consumer electronics, the company has sold a chemicals company, with 2,900 workers, and may also let go its U.S. headquarters building in New York go. At the same time, it has spent close to $2 billion on a U.S. game clouding company and a stake in medical equipment maker Olympus Corp.

Sony produced 74 million lithium-ion battery cells in July-September - almost 40 percent fewer than in the first quarter of 2008, when its output topped Samsung SDI Co Ltd's 110 million and LG Chem Ltd's 54 million, according to Techno System Research in Tokyo. Sony's market share is now 7 percent, dwarfed by Samsung SDI's 27 percent, Panasonic's 21 percent and LG Chem's 17 percent.

Sony's battery unit, which also makes button batteries for watches and smaller appliances and optical devices, has three factories in Japan and two overseas assembly plants in China and Singapore. It has yet to enter the more lucrative business for automotive batteries.

In its most recent filing, Sony valued the battery unit's fixed assets, including production sites and machinery, at 52 billion yen ($633 million). Under Sony's accounting rules, asset sales are typically booked as operating profit.

The cost to protect $10 million of Sony debt against default for five years has edged higher this week to almost $400,000. The CDS spreads had tumbled earlier this month - from above 480 basis points - after Sony said it would raise 150 billion yen ($1.9 billion) through a sale of convertible bonds.

($1 = 82.1200 Japanese yen)
