    Sony announced on Monday that it will introduce a new line of external batteries for smartphones and tablets. Shipping in capacities of 3,500 to 7,000mAh, these external juice boxes weigh around 198 grams and measure 130.6mm by 12.9mm, making them about the size of a modern smartphone. Charging devices via USB, Sony claims that these portable pick me ups can be recharged up to 500 times and can charge most smartphones in an hour and a half. If toting another smartphone-like device around doesn't sound ideal to you, Sony will also be releasing smaller "stick-type" (think flash drives) external batteries in assorted colors. Both battery types are set to launch this fall, with prices ranging from 2,300 yen ($30) to 7,000 yen ($90). Wouldn't it just be easier to sell a marginally thicker phone with world-class battery life? A boy can dream...

  • IEEE begins work on new cellphone battery standard, we circle 2029 for ratification

    You'll excuse us for poking a bit of fun at the IEEE, but after it took seven years to finalize a wireless standard that didn't change for most of that time, we have to wonder how long a new battery rulebook is going to take. IEEE Std 1725 is the current set of commonly agreed rules, in effect since 2006, but apparently "the cellular industry has grown tremendously since then" and our needs as consumers have changed. No kidding, 1GHz processors and 1080p video recording can kind of do that. The Cell Phone Battery Working Group (a real entity!) will hold its first meeting on the topic in February, and the final outcome will lay out up-to-date rules on the requisite quality, reliability, construction, and discharge characteristics of modern cellphone batteries. Let's hope "smartphones that last more than a day" figures somewhere on that list.

  • Fujitsu wants WiMAX handsets to last longer

    Although WiMAX handsets have not made it out into the wild yet, Fujitsu wants to make sure those mobile WiMAX batteries don't die so quickly. To that end, the Japanese company has developed some tech to enhance the power transmission efficiency of upcoming WiMAX handset amplifiers. With WiMAX transmitters needing large amounts of power to transmit data, any gain in the power efficiency of amp design is going to be welcome, we suppose. Fujitsu claims a power output gain of one and a half times what normal transmission amps get now in mobile WiMAX-equipped handsets. WiMAX networks are probably hitting en masse in 2008 -- if not before -- and conveniently, that's the date Fujitsu has set to commercialize this new tech. Perfect timing, eh?

  • Moxia's USBCELL charges mobile batteries from USB ports

    If you're one to actually remove the battery from your cellphone quite regularly -- do you yearn for that second backup battery to have built-in charging capability from a standard USB port? Moxia may have your answer, as its newer USBCELL battery product can charge without the need to carry along that extra charger. Yeah, we prefer to use our laptop PCs to charge or phones instead of a small, plug-in charger, which seems to be, umm, really difficult. Well, not really, unless you despise small and portable chargers (and many of them in your bag.) Now, we like the idea of many travel-friendly gadgets being able to be charged by a single USB-type charger -- but when taken just for a phone, the point of this device becomes, well, moot.
