Over the past few months, we've been introduced to new battery-conserving technology, battery-powering solar panel bags, and a battery that can be charged by your bike. But none of these new inventions address a fundamental battery gripe: charge time.
Enter Japanese mobile giant DoCaMo. The company has just introduced a battery case that promises 10 minute-charging time. The catch? You'll have to keep the charge case wrapped around your phone for the rest the time you use it after it's been charged.
The battery case works by pulling in power at a much higher rate; up from around .55amps to over 5.5amps, significantly reducing charge time. The reason why technology like this couldn't be embedded in a phone is that most are simply too small to offer pass-throughs of over 1.8amps.
It is unclear when this prototype will go mainstream, or where it will go when it does, but we'll let you know when we know.
UPDATE: We found video!
