Apple’s new iPhone 14 series has the same design and overall dimensions as the 2021 series (only a few fractions of a millimeter), so this shouldn’t come as a surprise, but battery capacities are pretty much the same too.
There are small differences, although probably not enough to have a measurable impact on battery life. The difference this year is that there are now two models with a large battery: the iPhone 14 Pro Max and the cheaper iPhone 14 Plus. Their batteries are slightly smaller than the 13 Pro Max battery, but again that’s a negligible difference.
| Battery | mah | Wh | Difference |
| iPhone 13 | 3,227 mAh | 12.4 Wh | + 2.18% |
| iPhone 14 | 3,279 mAh | 12.7 Wh | |
| iPhone 14 plus | 4,325 mAh | 16.7 Wh | – |
| iPhone 13 Pro | 3,095 mAh | 12.0 Wh | + 3.43% |
| iPhone 14 Pro | 3,200 mAh | 12.4 Wh | |
| iPhone 13 Pro Max | 4,352 mAh | 16.8 Wh | -0.42% |
| iPhone 14 Pro Max | 4,323 mAh | 16.7 Wh |
The batteries of the iPhone 14 and iPhone 14 Pro are slightly larger, but only by a small percentage. Like last year, the vanilla model has a larger battery than the Pro, but this year they also have different chipsets (and different screens, of course).
It will be interesting to compare battery life – Apple claims the Plus has the best battery life of any iPhone so far. Additionally, the Pro models deliver on their promise of “all day battery life” despite the new Always On Display feature.
As for the charge, Apple hasn’t announced official numbers, but regulatory documents suggest nothing has changed. The 3C lists 29W (14.5V, 2A) for one of the models, which should be pretty much the same as the iPhone 13 Pro Max, which is unofficially rated at 27W.
