When should the battery be replaced?
1. Check the battery health
Go to Settings → Battery → Battery Health. This shows the battery’s maximum capacity as a percentage of what it was when new. The lower the number, the shorter each charge lasts. If you see a service message, Apple itself recommends replacing the battery.
2. Watch for the signs
- It drains quickly, even though you use it as you always do.
- It switches itself off while there is still charge left.
- It has become slow. An iPhone with a worn battery can reduce its performance to avoid shutting down.
- It gets hot while charging or during normal use.
3. Is the battery swollen? Stop using the phone
If the screen is lifting on one side or the back is bulging, the battery may be swollen. Don’t charge it, and bring it to one of our shops. A swollen battery cannot be sent by post.
Is a new battery worth it?
If the rest of your iPhone works fine, a new battery is often a good way to make it last longer. Not sure if it makes sense for an older model? Read repair or sell your old iPhone – or ask us in the shop.
