iPhone getting hot
An iPhone usually gets hot because it’s working hard: games, video, navigation, charging or lots of apps in the background. Sun and warm surroundings make it worse. A little warmth is normal, but if it gets very hot for no reason – or shows a temperature warning – the battery or another part may be worn.

Why is my iPhone getting hot?
Demanding apps and games
Games, long video calls, the camera and GPS make the processor work, and that creates heat.
Charging
The battery gets warm while charging – especially with a fast charger, or if you use the phone at the same time. Read more in why does my phone get hot when charging?
Sun and heat
If the phone is lying in the sun or in a hot car, it can’t get rid of the heat. The iPhone may then show a warning and switch off features until it has cooled down.
Software faults and background activity
A buggy app, an update in the background or old software can use more power than normal.
Worn battery
An old battery gets hotter and lasts less time. Check the battery health under Settings > Battery.
How to cool your iPhone down
- Close heavy apps, and unplug it from the charger.
- Take off the case, and put the phone somewhere cool and shady.
- Switch it off completely if it’s very hot. Don’t put it in the fridge – the cold can cause condensation.
- Update iOS and your apps once it has cooled down.
