Yesterday Texas Instruments introduced a couple of new chipsets (fuel gauge an charger ICs) designed to improve the charging speed and life expectancy of single-cell Li-ion batteries. The technology, called MaxLife, is expected to provide an improvement of up to 30 percent in battery service life and faster charging times. Cell impedance is carefully monitored by the fuel gauge chip while the charger IC uses a model of battery degradation to charge the cell in the most optimal way. Both chips are connected via an I2C bus to form an autonomous battery management system which, according to the company, is safer and more thermally efficient than existing solutions. The two chipsets (2.5A and 4.5A) are now available along with a development kit, so it's only a matter of time until this technology lands into handsets and other devices that use single-cell Li-ion batteries. Check out the details after the break.
While the semi-annual parade of new smartphone models at NTT DoCoMo often reveals some unexpected devices, this summer it had a bumper crop: we've already seen the new Sony Xperia A, Sharp's Aquos Phone Zeta and Aquos Pad SH-08E plus a Galaxy S4 in "arctic blue." Seven more phones round out the lineup and NTT DoCoMo is trumpeting 2,100 mAh minimum batteries, LTE, NFC and quad-core processors for the entire gamut. Other standout models include Fujitsu's 5.2-inch, 1080P Arrows NX F-06E, a model with a 16-megapixel camera you'll likely never see stateside, Panasonic's Eluga V P-06D with a 4.7-inch 1080P screen and a whopping 2,600 mAh battery, and Disney Mobile's F-07D, which should be an endurance wonder with a 720P screen and 2,600mAh cell. Naturally, there's a rainbow of new hues for most of the models, which will roll out over the summer in Japan -- click the source link PDF for detailed specs or check the PR after the jump.

For the most part, battery packs have become what CD cases were in the late 90s -- generic and utilitarian. Nokia's new DC-18 portable chargers dare to be different. The sharp, tile-like designs house a modest 1,720 mAh cell, retractable micro-USB cable (that doubles as a a switch,) plus an LED battery level indicator that lights up when you extend the aforementioned appendage. It's available in four colors (red, white, yellow and blue), but only in select regions right now. No word on when and for how much, but color-coordinators can keep pinging the source to find out.
30/11/2012 - Mugen Power offers massive 6,400mAh Galaxy Note II battery, tests the limits of our pockets
Is the already insanely long battery life of the Galaxy Note II just not enough? Mugen Power's new extended battery might not have Samsung's giant smartphone running forever, but it sure will feel like an eternity. At 6,400mAh, the replacement has more than twice the capacity of the Galaxy Note II's stock 3,100mAh pack while keeping the NFC wireless. Just don't expect to shove the resulting franken-phablet into a tight pants pocket -- like most such batteries, Mugen's is much thicker than the default and even comes with its own kickstand to save wrist strain during a movie marathon. The pack normally costs $106 and is listed as working with most any Galaxy Note II variant, including at least the American variants for AT&T, Sprint, T-Mobile and US Cellular. Those who can bide their time until the quoted December 21st ship date will end up with a tank of a smartphone, but one that might just last a whole weekend away from a wall outlet.

If you were put off by the price of Goal Zero's Sherpa, then here's something that might be more deserving of that slot in your backpack. The Switch 8 Solar Charging Kit costs $100 and bundles together a 2,200mAh battery and Nomad 3.5 solar panel. The manufacturer says that the 8-watt dynamite-shaped battery can be tanked up via sunlight in six hours, although this time can be reduced to four if you use a USB power source before you head into the wilderness. Interchangeable tips, which will be sold separately in the coming months, will allow compatibility with a variety of devices and also let you use the battery pack as a fan or flashlight -- no cranking or pedaling required.

04/06/2012 - Vodafone's recharging truck returns for the 2012 festival season, wants to scan your hand
A new and improved version of Vodafone's massively mobile multiple handset recharger is being rolled out just in time for thousands of festival-goers to all hold up their phones to record the same Black Keys performance. The revamped truck still does that whole charging 2,000 phones at once thing, but adds DJ booths and new hand scanners to help phone owners more efficiently retrieve their gadgets, when it comes time to check into Foursquare -- you don't want someone else to become the mayor of the chillout tent, after all.

At the Frequencies media summit in Seattle over the last two days, HTC walked us through the fine details on how its smartphones are developed, going from the boring rectangular ABS block to the more refined plastic mockups that are presented to carriers and focus groups -- the findings of which then shape the final product. Sadly, we weren't allowed to take photos of the One X mockups that were shown to us, but do read on to learn the general process of how an HTC phone goes from inception to the final product.

Sure, we all love having the latest and greatest smartphone from the likes of Samsung, but the power consumption driven by larger displays, LTE, and more use is making it increasingly harder to get through the day. Samsung's vice president of product innovation, Kevin Packingham, said in an interview with CNET that Korea's darling has set the lofty goal that smartphones coming out this year last an entire day under average to moderately heavy use. Samsung's plans include beefing up batteries, but it also intends to look at improving energy efficiency by tweaking the various radios -- LTE, WiFi -- to make them a little less greedy. Motorola has already seemingly caught this wave with the RAZR MAXX -- a slightly chubbier Motorola RAZR -- which is essentially the same set as the RAZR but with enough juice so you can use it instead of spending your day looking for an outlet to charge it. Unfortunately, things could get sticky as the definition of "moderately heavy use" is a pretty tough thing to pin down. Would you put up with a huskier phone to get you through the day or is a slim set more important? Feel free to chime in with your comments below.
