How to check battery health on iPhone?
You can check iPhone battery health from Settings to see how much capacity the battery still holds and whether iOS has detected a service issue. This is the fastest way to understand whether poor battery life is caused by normal aging or by something else.
Steps
- Open Settings on your iPhone.
- Tap Battery.
- Tap Battery Health or Battery Health & Charging.
- Review Maximum Capacity and any service recommendation shown on the page.
What the battery health section means
- Maximum Capacity shows how much charge the battery can hold compared with when it was new.
- A lower number can mean shorter screen time and more frequent charging.
- A service message usually means the battery may need professional attention.
Pro Tip
- Check battery health when the phone is cool and not plugged in so the reading is easier to interpret.
- Do not judge battery condition only by one bad day of usage, because brightness, apps, and signal strength can also affect battery life.
- If the percentage is still decent but runtime feels poor, review background activity before assuming the battery is failing.
