Quick Fixes
1. Remove the Case Temporarily
Cases trap heat. Remove it for 5–10 minutes to cool the device faster.
2. Close Heavy Apps
Swipe up → Close apps like Instagram, TikTok, Amazon, Facebook. These apps frequently spike CPU usage.
3. Lower Screen Brightness
Settings → Display & Brightness → Reduce brightness. High brightness is a major heat source.
4. Turn Off Background App Refresh
Settings → General → Background App Refresh → Off. Reduces background CPU load.
5. Disable Location Services for Unneeded Apps
Settings → Privacy → Location Services. Set most apps to "While Using."
Advanced Solutions
1. Reset All Settings
Settings → General → Transfer or Reset iPhone → Reset All Settings. Fixes overheating caused by corrupted system preferences.
2. Update to Latest iOS
Apple has released patches improving thermal control on iOS 26.
3. Turn Off 5G Temporarily
Settings → Mobile Data → Voice & Data → 4G. 5G modems run hotter in weak signal areas.
4. Remove Recently Installed Apps
Some apps cause runaway CPU usage. Delete → Restart → Reinstall.
5. Avoid Using the Phone While Charging
Charging + heavy use = guaranteed heat buildup.
