How to Fix iPhone 12 Pro Overheating

Trying to fix your iPhone 12 Pro overheating?

Apple’s new iPhone 12 Pro is a beautiful addition to Apple’s extensive catalog of iPhone models. The old-school iPhone 5-inspired design caught the attention of many Apple enthusiasts, especially for the reminiscent aesthetic of rectangular cases.

Unfortunately, costing you about $1,000, finding that it overheats with the simplest applications is probably the last thing you expected. This pressing issue is a huge problem and about 1,500 other people, most likely more, share the same issue.

From configuring your settings, resetting preferences, and possibly factory resetting your device, we’ll guide you through multiple solutions that you can do to try and fix this problem. Here’s how you can fix the iPhone 12 Pro overheating issue.

Let’s get started!


1. Foreword.

While other websites might prefer having a longer list for SEO purposes, here at Saint we understand why you came here and will not sabotage your experience at trying to solve this problem with bogus solutions.

The methods below will not tell you to use low power mode, delete apps, turn off your 5G connection, and so on. These features should typically come with the iPhone 12 Pro and your experience should not be limited just so you can stop your iPhone from overheating.

With that in mind, we’ll include alternatives at the end of this article that do involve your settings just so we can cover everything.


2. Remove Your iPhone Case.

Buying a new iPhone usually comes with getting yourself a new phone case. While we understand that this experience can be quite exciting, unfortunately, your new iPhone case could be the source of this problem.

This is especially common with thick black rubber phone cases, so try taking that off and see if that helped cool off your iPhone. While this might feel like a temporary fix, this is a great way to troubleshoot if your iPhone 12 Pro does overheat without the case.

If your iPhone remains cool after removing the case, then chances are you’re going to have to buy a different phone case. Hopefully, try to get one that isn’t as thick.


3. Use An MFi-Certified Charger.

While the iPhone 12 Pro doesn’t come with a charger, this controversial decision from Apple could be what’s causing the problem here. Without the right MFi-certified charger, you run the risk of charging your iPhone with a defective adaptor.

MFi-certification is an abbreviation for ‘Made For iPhones/iPads’. These chargers are certified by Apple and are safe to use for your iPhone. If your iPhone overheats especially when it’s charging, then it may be an issue with your possibly fake adaptor.

Try buying an MFi-certified charger or borrow one from your friends who also have an iPhone 12 Pro. The simple switch could save you a lot of time and possible hazards since fraudulent chargers can be dangerous.


4. Disable Background App Refresh.

Although we did say that we won’t be configuring your settings, the ‘Background App Refresh’ feature takes the cake for being the cause of multiple overheating problems. Even for older devices that have recently updated to iOS 14, the ‘Background App Refresh’ feature can still overheat perfectly good old iPhones and Apple Watches.

The ‘Background App Refresh’ option helps your apps stay on top of everything and continually lets them refresh to bring you the latest news and notifications. Disabling this doesn’t really take out a lot of functionality, but you might receive less recent notifications.

Here’s how you can disable the ‘Background App Refresh’ feature:

  1. First, open up your Settings app and go to the General tab.
  2. From there, look for and tap on Background App Refresh and disable the feature.

Feel free to experiment with the different ways that you can configure and schedule these refreshes. Other than that, use your iPhone for a couple of hours and see if it still overheats.


5. Monitor Your Applications.

Even though your iOS version is still the same as most iPhone models, the new features and hardware from the iPhone 12 Pro can still incur bugs from iOS 14. These issues can be simple, like your operating system running into errors trying to communicate with your hardware.

Try to go over any recent applications that you installed, open them one by one, and see which one heats up your device. A lot of people have this issue with Instagram, their Camera app, or even just simple text messaging.

If your iPhone heats up regardless of the app or with apps that are essential to you, you can go ahead and proceed to the next method. However, if you can isolate this problem and find that the cause is just one app, then you should uninstall the problematic application or update it into a more stable version.


6. Update Your iOS To The Latest Version.

Apple’s iPhone 12 Pro model came out with a lot of bugs that, thankfully, Apple has been made aware of. Depending on when you’re reading this article, you may have an update pending that could fix this issue.

Running the latest iOS version on your iPhone can save you from a lot of software errors and issues, which is hopefully the cause of this issue. If the problem is with your iPhone’s hardware, you may have to take the warranty and have it replaced by Apple.

Updating your iOS to the latest version can take a while, depending on the size of the update. Please keep in mind that this will consume your internet’s bandwidth. Also, try to make sure that you have at least 50 percent battery life before updating your iOS.

Before you do that, here’s how you can update your iOS to the latest version:

  1. Go ahead and open up your Settings app from your home screen.
  2. Now, look for and click on General and navigate to Software Update.

  1. If an update is available, a clear indication should be shown on your screen. Simply tap on Install Now to begin downloading the update.

Once you’ve successfully updated your iPhone 12 Pro to the latest iOS version, try browsing through a couple of apps and see if your iPhone still overheats. Hopefully, this helped you fix your iPhone 12 Pro overheating issue.


7. Give It A Couple Of Days.

Finally, you might want to give it a couple of days. The warranty to return your iPhone lasts about 14 days anyway, so there’s no rush in replacing it with another model that might be just as defective.

If the heat isn’t extremely hot but instead is just warm to the touch, perhaps a software update or a couple of days can make all the difference. Your iPhone 12 Pro isn’t just downloading new apps, it is also reconfiguring your settings and perhaps calibrating the backup data that you restored into it from your previous iPhone.

This process can take a while, but it’s worth noting that these issues can sometimes fix itself. However, please do not hesitate to contact Apple’s customer support to let them know that you’re one of the thousands of people who are experiencing this issue.

In most scenarios, Apple might even provide you with a replacement to try and get the defective model off your hands. Other than that, refer to our other guide for the nitty-gritty solutions that you can try around your settings to help you fix this problem.

Lastly, knowing how to factory reset your device is always a helpful skill for the most desperate of times. Our guide will help you through this complicated process while educating you on the difference between a regular factory reset and DFU mode.

Now that you’ve reached the end of this article, hopefully we’ve helped you fix iPhone 12 Pro overheating. If you have any questions or clarifications, feel free to leave us a comment down below.
