A slew of reports talked about the iPhone 14 series being thicker, in part thanks to the larger camera sensor, which will also cause these models to tout a bigger bump, but also because Apple needs to make room to accommodate bigger batteries. If you needed to know the size of the cell in each iPhone coming later this year, a leak shares the capacities of all four models.

With the ‘mini’ version not lined up for a release, Apple will have no excuse to use smaller-sized batteries in every iPhone 14 model launched. According to the image shared by ShrimpApplePro, that appears to be the case, though he does suggest his audience to treat those numbers with a pinch of salt. To recap, the iPhone 14 and iPhone 14 Pro will have a 6.1-inch screen, and this will be the smallest display size out of the entire lineup.
