How to prevent overheating problem on iPhone 12?


1. Get Rid of the Faulty iPhone Case.

We have created several roundups of the best iPhone 12, 12 mini, 12 Pro, and 12 Pro Max cases, including clear, bumper, cute, and leather covers. If you need a case with a better heat dissipation design, do check out our lineups.

2. Be Sure to Force Quit Apps If You Aren’t Using Them

Swipe up from the iPhone home button and hold along the middle of the screen to access the app switcher. After that, swipe up on an app card to quit the app. Quit all the open apps.

3. Make Sure You are Using MFi Certified Chargers

They are also the main culprits behind the “Accessory may not be supported” error. So, always stay away from uncertified chargers.

4. Hard Reset Your iPhone 12 to Fix Overheating Issue

Press and release the volume up button. After that, press and release the volume down button. Next, hold down the side button until the Apple logo shows up. Once your iPhone 12 has rebooted, try using it for some time to check if you have got the better of the overheating issue.

5. Disable Background App Refresh

Go to the Settings app on your iPhone -> General -> Background App Refresh. Now, you can either completely turn off background app refresh on your iOS device or allow only a few important apps to refresh in the background. I would suggest you turn it off right now. If that resolves the issue, you can allow some important apps to refresh in the background later.

For those unfamiliar, background app refresh enables apps to run smoothly. That’s why it’s turned on by default.

6. Stop Continuous Location Tracking

Navigate to the Settings app on your iOS device -> Privacy -> Location Services. Now, turn off the Location Services switch to disable it altogether. If you don’t want to disable it, allow only specific apps to track your location. For better control, iOS offers three options to choose from:

    While Using the App: Allow an app to access your location only when you are using it.

7. Update All Apps and Remove All the Storage-Hogging Files

I would recommend you optimize the storage of your iOS device by cleaning up all the storage hogging files. Cluttered storage causes the device to become sluggish, and that invites two other major problems, including unexpected iPhone 12 battery drain and overheating.

Tap-on-Update-All-option

iOS lets you automatically update apps. So, if you often forget to update apps on your iPhone, be sure to use the automatic update feature. Go to Settings app -> App Store. Now, turn on the switch right next to App Updates. Besides, you can also choose to update apps manually. To do so, navigate to App Store -> your profile. On this screen, you will get the option to update one app at a time or update all apps at once.

Check iPhone storage - fix iPhone 12 Overheating Issue

Before removing the clutter on your iPhone 12, head over to Settings app -> General -> iPhone Storage. Here, you can check out the breakdown of how the storage has been consumed on your iPhone 12. Also, take a close look at all the apps and the amount of storage each one uses on the device.

Once you have checked out the storage consumption, clean up the redundant files and useless screenshots. Additionally, make sure to delete all the apps that you hardly use.
8. Reset All Settings

Removing the existent settings and putting the device to factory default is the sort of solution that comes in handy while dealing with complex iOS issues. That’s the reason why I never miss out on it. Do note that when you reset your device, iOS only removes the existing settings, including Wi-Fi and website settings. All of your apps, media, and data will remain secure, so you don’t need to worry about losing anything.

9. Update Software

If your iPhone 12 is still overheating and none of the solutions mentioned above work in resolving this problem, the issue might be due to a software bug. Apple releases software updates quite frequently to fix bugs and also enhancing the overall performance.

10. Restore Your Device As New

Restoring the device as new is considered to be the last resort, so you should move ahead with this solution carefully. It will wipe out all the existing data on your device, including photos, videos, and music.
