Leaker Majin Bu initially mistakenly reported on the iPhone 17 Pro battery, later correcting it and revealing details about both the iPhone 17 Pro and iPhone 17 Air batteries. The iPhone 17 Pro will reportedly have different battery sizes depending on the region, with US models larger due to the absence of a physical SIM card tray. The iPhone 17 Air battery is said to be 2,900mAh, 2.49mm thick, and housed in a steel case, raising questions about its SIM card compatibility. Further details will be revealed at the official iPhone launch next month.
