Apple promised improved battery life for its new iPhone 5s and 5c, but other than endurance times for a few use cases, the company gave little info on the battery itself. Luckily, it's FCC's job to certify such aspects of a mobile device so now we have the actual battery capacity.
The iPhone 5, 5s and 5c batteries all work at 3.8V, but differ in battery size. The iPhone 5 had a 5.45Wh battery which works out to 1,440mAh. The iPhone 5c has a bigger, 5.73Wh battery or 1,507mAh and the iPhone 5s has the biggest battery of the three at 5.96Wh or 1,570mAh.
It's interesting that the iPhone 5s battery grew more, even though the phone is as thin as the iPhone 5, while the 5c is thicker.
Made the switch from the iphone5 to the blackberry q10. Having a spare batt on hand is clutch
I have bought an iPhone 5S, but I find ios7 drain battery rapidly. It's pretty not convenient because of its irremovable battery, especially when I go out. I recently bought a portable charger from Kinkoo: http://www.ikinkoo.com/shop/portable-charger...
