What the symptoms may tell you
A short runtime can come from battery wear, heavy app use, weak signal, background activity or temperature. A percentage reading alone is not a complete diagnosis.
Safe checks to try first
- 1Review Battery settings for recent app activity and battery health where your model shows it.
- 2Compare normal use over a day with a day of unusually heavy camera, navigation or hotspot use.
- 3Check for a recent software update and note whether drain began immediately afterwards.
What to avoid
Do not continue to use or charge a swollen, damaged or unusually hot battery.
Next step
Send the iPhone model, battery health reading if available, age of the battery and a description of normal runtime.
What I can help with
A straightforward battery replacement is offered by model quote. It cannot fix every source of high power consumption.
