An alleged iPhone 14 battery specs leak claims there's some minor improvements, plus one surprise downgrade, for the four rumored upcoming models.

These supposed new capacities work out as a 1% increase for the iPhone 14 over the iPhone 13, a 3% increase for the iPhone 14 Pro over the iPhone 13 Pro and a 1% decrease for the iPhone 14 Pro Max compared to the iPhone 13 Pro Max.

The iPhone 14 has a slightly larger battery than the iPhone 14 Pro according to these specs, despite the fact that these phones should share the same 6.1-inch body.

The new iPhone 14 Max model will apparently have the largest capacity battery, but only by a small amount compared to the iPhone 14 Pro Max.

This model could have the best battery life out of any of the iPhone 14 models as a result, but the battery savings enabled by a ProMotion adaptive display refresh rate could still mean the iPhone 14 Pro Max is the winner.

Speaking of Pro Max models, the iPhone 13 Pro Max has a 4,352 mAh battery, so the 14 Pro Max would actually be downsizing by 29 mAh according to this rumor.

As well as still being a fairly large battery, a more rumored efficient A16 chipset (something the non-Pro models may not get) and the adaptive refresh rate we already mentioned could help give the iPhone 14 Pro Max excellent longevity.
