In September, it went from 94% to 93% to 92%, and in October it went from 92% to 91% to 90%. in November it went from 90% to 89% to 88% health.

We were a little concerned last year when the iPhone 12 Pro rolled out with a 2,815mAh battery, which was a regression from its predecessor. Thankfully, the iPhone 13 Pro ups the capacity to 3,095mAh. The iPhone 14 Pro Max actually has a smaller battery capacity than its successor, the iPhone 15 Pro Max. So the iPhone 15 Pro Max will take slightly longer to charge, despite its USB-C port. (The USB-C port on new iPhones has no effect on charging times.) The iPhone 12 has a 10.78 Wh (2,815 mAh) battery, a slight decrease from the 11.91 Wh (3,110 mAh) battery found in the iPhone 11 and identical to the battery found in the iPhone 12 Pro. The iPhone 12 Mini has a 8.57 Wh (2,227 mAh) battery. Like previous iPhones, the battery is not user-replaceable. Chipsets HOEmMZC.
