Your iPhone becomes unusually hot, slows down, or shows a temperature warning. Overheating can be caused by software bugs, background processes, or hardware issues. These steps help cool the device and prevent further damage.
1. Remove the Case
- Cases trap heat and slow cooling.
- Remove the case until the phone returns to normal temperature.
2. Stop Charging
- Unplug the charger immediately.
- Charging generates heat, especially with fast chargers.
3. Close Background Apps
- Swipe up and close all running apps.
- High‑intensity apps (games, GPS, video editing) generate the most heat.
4. Move to a Cooler Environment
- Avoid direct sunlight, hot cars, or warm rooms.
- Place the phone in a shaded, cool area.
5. Restart the iPhone
- Hold Side button + Volume button → Slide to power off.
- Turn it back on after 30 seconds.
6. Update iOS
- Go to Settings → General → Software Update.
- Updates often fix overheating bugs.
7. Check Battery Usage
- Go to Settings → Battery.
- Look for apps using excessive power.
- Delete or update apps that consistently overheat the phone.
8. Reset All Settings
- Go to Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings.
- This does not delete your data.
9. When to Seek Repair
- iPhone overheats even when idle.
- Device shuts down due to temperature repeatedly.
- Battery health is below 80%.
- Overheating started after a drop or liquid exposure.
If overheating continues after these steps, the issue may be related to the battery, power IC, or internal hardware. A technician can diagnose the exact cause.
