Why yes, FastMac -- we want 24 hours of talk time, 72 of audio, 20 of video, and 31 hours of standby on our iPhones and iPhone 3Gs. Throw in a camera flash that doubles as a flashlight, and the ability to charge a USB device like a Bluetooth headset right off the phone, and you've got a deal on this iV charging kit of yours! Oh, there's a catch? It's a wee bit bulky, with an aesthetic similar to that of mophie's Juice Pack? Hey, it could be worse. This largification -- along with $79.50 -- is apparently the price you pay for digital endurance.

We're still not entirely clear if Philips' Xenium 9@9k, you know, actually exists, but according to iDNES, this handset can last a whopping two months without needing a recharge. Granted, the Xenium line has traditionally boasted impressive battery life, but this particular iteration will purportedly last up to 1,440-hours in standby and 17-hours while yapping. Additionally, the tri-band GSM mobile sports an FM tuner, Bluetooth, a VGA camera and a microSD expansion slot. Beyond that, everything else gets lost in translation, but here's to hoping a few more manufacturers step up their game in the longevity department.

Apple's tooting its own horn about some new spec upgrades to its imminent iPhone. No, it's not 3G, GPS or anything crazy like that, but we'll settle for a battery life upgrade anytime, and screen durability doesn't hurt neither. Apple claims that its preliminary estimates of 5 hours of talk time, internet use and video playback were a tad conservative, and the iPhone instead will be boasting of 8 hours of chatting, 6 hours of internet and 7 hours of video. Audio playback has been boosted from 16 to 24 hours, and standby is at a welcome 250 hours. Of course, Apple does have tendency to exaggerate slightly on the battery life front, but these are promising figures, and should manage to provide a day or two's worth of solid use out of the thing. On the screen side, Apple has upgraded the original plastic surface of the phone to some "optical-quality glass" to improve scratch resistance and clarity. Check after the break for a handy battery life chart.

Update: Not sure how we missed this little snafu, but no Apple, you aren't the only one on that chart with WiFi.

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?

While those lusting for love may be enthralled about Motorola's newfound method of extended your chances on ProxiDate, the researchers behind the parasitic cellphone patent probably had more critical scenarios in mind. In cases where your battery life is running flat, situational demands may leave you wondering how you're going to contact your laundry list of emergency contacts with such little juice. The patent spells out an automatic shutdown feature that disables all non-essential functions (including accepting incoming calls), which allows the Bluetooth transceiver to search for "compatible proxy phones" nearby. The sputtering device can then use the proxy cellphone to "send a warning text message to everyone on your pre-arranged emergency list," alerting them of your predicament and that you can only receive SMS messages (for a limited time). Of course, this brilliant plan will only work if indifferent strangers leave their mobiles open for Bluetooth syncs (not likely), and then don't mind you racking up their monthly bill with costly text messages (even less likely).
