Nowhereelse posted photos of the battery from Huizhou Desay which indicates a capacity of 2,915 mAh. That's much larger than the current battery for the iPhone 5s which has a capacity of only 1,560 mAh.
Of course, the larger battery is needed to power the larger display; however, we are hoping that Apple has heard consumer complaints and has taken steps to boost the battery life of its next generation devices.
For those wondering about the 4.7-inch iPhone 6, it's rumored to have a 1,810 mAh battery.
