Apple is quite selective when it comes to announcing the specs of their products. In the case of the iPhone 13, Apple mentions that the iPhone 13 mini and the iPhone 13 have 1.5 hours and 2.5 hours more battery life than its predecessor, but that was it. It’s hard to say if these gains in battery life are due to chipset efficiency or simply a larger battery.
For those who want more concrete numbers, the folks at 9to5Mac have discovered a filing on the Chemtrec website in which they have revealed the battery sizes for Apple’s new iPhone 13 models.
Based on these numbers, it appears that the iPhone 13 mini will have a 9.57 watt hour battery, an increase from the 8.57 watt hour battery in its predecessor. The iPhone 13 will have a 12.41 watt hour battery, up from 10.78 watt hour from the iPhone 12. As for the Pro models, the iPhone 13 Pro will come with an 11.97 watt hour battery, up from 10.78 watt hour, while the iPhone 13 Pro Max is packing a 16.75 watt hour battery, a jump from the 14.13 watt hour battery from 2020’s model.
It looks like Apple pretty much just increased the battery sizes across all the models, and that’s a good thing. However, exactly how much more battery life you will get will depend on how you use your phone, so that’s something to keep in mind.
