GoKawiiliPhone 15 Pro Max battery health hits 81% at 1,000 charge cycles
A writer's iPhone 15 Pro Max has reached 1,000 charge cycles, the threshold Apple designed the device to endure before battery health falls below 80 percent, and it now reports 81 percent health. The phone hasn't triggered iOS's battery service warning, but the owner says daily screen-on time has dropped sharply from over 12 hours when new to barely lasting until evening now.
