iPhone 15 Pro Max reaches 1000 charge cycles after three years
An iPhone 15 Pro Max user reports the device has completed 1,000 charge cycles after three years of use.

Battery design targets higher cycle counts
Apple states that older models are built to keep 80 percent capacity at 500 cycles. The iPhone 15 series and newer devices double this target figure. These phones are designed to finish 1,000 charge cycles before health drops below the 80 percent threshold.
Cycle count tracking starts with new models
The iPhone 15 lineup was the first to show the battery cycle count on screen. A full cycle occurs when the device uses its total capacity, even if split across multiple charges. The user notes that their specific phone recently hit this milestone.
Previous performance management controversy explained
Users previously reported slowdowns as batteries aged during a 2017 event known as batterygate. Apple clarified that slowing down was intentional to prevent unexpected shutdowns on degraded batteries. The company later added a toggle to override this performance management feature.
