You can try the following steps in order from simplest to most complex:
1. Immediately Cool Down Your Apple iPhone 12 Pro Smartphone Battery and Basic Checks
Physical Cooling: Immediately stop using the phone, remove the case, and move it to a cool, well-ventilated area (such as an air-conditioned room) to cool down. In extreme cases, you can turn off the phone to accelerate cooling.
Check Accessories: Ensure you are using an Apple MFi-certified charging cable and adapter.
2. Optimize Software and System Settings
Turn Off Background Apps and Refresh: In Settings > General > Background App Refresh, turn off background refresh for infrequently used apps.
Manage Power-Draining Apps on Your Apple iPhone 12 Pro: In Settings > Battery, view the battery usage rankings for the past 24 hours on your Apple iPhone 12 Pro. For apps with abnormally high battery consumption, try turning off their background refresh or uninstalling and reinstalling them.
Enable Low Power Mode: Enable Low Power Mode in Settings >Apple iPhone 12 Pro Smartphone Battery. This can effectively reduce battery power consumption and heat generation on your Apple iPhone 12 Pro.
Turn off unnecessary connections: When not in use, turn off 5G, Personal Hotspot, Wi-Fi, and Bluetooth in Control Center.
Update your system and apps: Ensure your iOS and all apps are up-to-date. This can fix many software bugs that cause overheating.
3. Reset settings (without deleting data)
If the above methods don’t work, try going to Settings > General > Transfer or Reset iPhone and selecting “Reset All Settings.” This will reset system settings such as network and keyboard, but will not delete your photos, apps, or other personal data.
4. Replace your Apple iPhone 12 Pro battery
If your Apple iPhone 12 Pro Smartphone Batteryhealth is below 80%, replacing it with an official or reputable Apple iPhone 12 Pro battery is one of the most direct and effective ways to resolve the overheating issue.
