Re: Longer battery life
They do, plenty of phones last a week.
But did you buy a phone that didn't meet your requirements? If so, surely then Samsung or whoever got your hard earned dosh thinks well, he bought it anyway, so why worry.
Unfortunately for most, a £30 battery pack and a £3 micro usb cable fixes the problem for all phones.Fro the rest, the phone only has to last from home to office, and then goes and charge and office to home again.
