I use my iPhone 15 Pro Max for high-end mobile gaming, 4K video recording, and continuous GPS navigation while charging over MagSafe in a hot environment. Within 10 months, my Battery Health dropped down to 84% with around 450 charge cycles completed.
What is the realistic charge-cycle threshold for genuine Apple OEM lithium-ion batteries under continuous heavy load before throttle states (throttling CPU via peak performance capability) occur? How does degradation differ between pre-iPhone 15 (500 cycles) and iPhone 15/16/17 models (1000 cycles)? When should I visit an authorized repair center for a genuine battery replacement?
