The iPhone 5c and 5s have bigger batteries than the iPhone 5
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.
| V | Wh | mAh | |
| iPhone 5 | 3.8 | 5.45 | 1,440 |
| iPhone 5c | 3.8 | 5.73 | 1,507 |
| iPhone 5s | 3.8 | 5.96 | 1,570 |
