iPhone 6 vs iPhone 5S: Battery

With such a boost in screen size the iPhone 6 inevitably needs more power, and so Apple has equipped it with an 1,810mAh battery.

Apple will have done some work to optimize the hardware and deal with power management efficiently, but it has been a weak point for the iPhone 5S, so the iPhone 6 really needs a bit more stamina. Apple claims it equals or beats the iPhone 5S battery on everythingWe'll have to get a real world hands-on to really assess it.
