We've already seen alleged 1,810mAh, 2,100mAh, and 2,915mAh batteries bound for Apple's upcoming handsets and now the strongest 2,915mAh module has been showed off on a set of new photos posted Tuesday morning by the French publication NowhereElse.fr [Google Translate].
Featuring a capacity of 2,915mAh versus the iPhone 5s's 1,560mAh package, this prototype battery should theoretically allow the iPhone 6 to last longer on a single charge and get your through the day without recharging.
On the other hand, it's entirely possible that Apple will advertise the iPhone 6 as having the same battery life as the iPhone 5s. That's because an increase in the battery capacity could be offset by a bigger screen which draws more power. Same could be said for other rumored new components such as an NXP-made NFC chip for mobile payments, faster graphics and more.
