On iPhone 14 and earlier it may be called Battery Health & Charging.
What the number means
Maximum Capacity is the battery's charge compared with when it was new. It drops as the battery ages.
- Apple designs iPhone 14 and earlier batteries to keep 80 percent of their capacity at 500 full charge cycles, under ideal conditions.
- iPhone 15 models: 80 percent at 1000 full charge cycles.
If the iPhone says the battery's health is significantly degraded, Apple says that is not a safety issue, but the battery needs service to get full performance and capacity back.
When to replace it
- The phone dies before the end of the day.
- It shuts off with charge still showing.
- Battery Health shows the significantly degraded message.
- The screen lifts or the back bulges: stop using it and read Swollen phone battery: what to do.
