Is Your iPhone Getting Too Hot?
iPhones are designed to operate between 0° and 35°C (32° to 95°F). When your device exceeds this range, iOS will show a temperature warning and throttle performance. Persistent overheating can degrade battery life and, in extreme cases, damage internal components.
Why Is My iPhone Overheating?
The most common reasons include:
- Charging while using the phone (especially with wireless charging)
- Running demanding apps like games, video streaming, or AR apps
- Direct sunlight or leaving the phone in a hot car
- Background app refresh running too many processes
- Outdated iOS with known thermal management bugs
- A case that traps heat
- A degraded battery working harder to hold charge
Immediate Cooling Steps
1. Remove the Case
Phone cases — especially thick rubber or leather ones — trap heat. Remove the case and let the metal back dissipate heat directly.
2. Move Out of Direct Sunlight
Never leave your iPhone on a dashboard, windowsill, or outside in direct sun. Even 10 minutes can cause serious overheating.
3. Stop Charging Temporarily
Charging generates heat. If your phone is already hot, unplug it and let it cool to room temperature before resuming charging.
Software Fixes
4. Close Background Apps
Swipe through your recent apps and close everything you’re not actively using. Background processes accumulate and generate heat.
5. Turn Off Background App Refresh
Go to Settings → General → Background App Refresh and either disable it entirely or turn it off for specific apps.
6. Reduce Screen Brightness
The display is one of the biggest heat sources. Swipe into Control Center and lower brightness. Enable Auto-Brightness under Settings → Accessibility → Display & Text Size.
7. Enable Low Power Mode
Go to Settings → Battery → Low Power Mode. This reduces background activity and processor load significantly.
8. Update iOS
Apple regularly patches thermal management issues. Go to Settings → General → Software Update and install any pending updates.
9. Check Battery Health
A battery below 80% capacity works harder and generates more heat. If your battery health is low, consider a replacement — it often resolves chronic overheating.
When to Worry
If your iPhone overheats while doing nothing, shows the temperature warning frequently, or the back gets uncomfortably hot to hold, there may be a deeper hardware issue. Book a diagnostic at Apple Support.
