iPhone 12 Pro Max Overheating
iPhone 12 Pro Max Overheating

Overheating doesn’t just make your iPhone hot to touch. It can also lead to rapid battery drain, unresponsive touch screen, and, in extreme cases, automatic shutdown. iPhones, like all smartphones, are designed to work within a certain temperature range. When it exceeds this range, your iPhone alerts you and takes measures to protect itself.

It appears that both the iPhone 13 Pro Max and iPhone 12 Pro Max have overheating problems (especially after iOS updates). This has been reported by several people, and we have seen a number of such phones pass through our store. Due to their hardware, the Pro versions typically run a little hotter, but if the overheating gets out of hand, you run the danger of breaking the phone or worse.

If you’re experiencing this problem, the first thing you must determine is whether your phone just received an iOS update or not. If so, performing a forced restart is the first step in examining it. Take these actions:

Step 1: Forced Restart

1) Push the Volume Up button, then immediately release it.

2) Quickly press and release the Volume Down button.

3) Hold down the SIDE button while waiting for the Apple logo to show. This could take up to 20 seconds. When prompted to slide the power off, DO NOT let go of the side button.

If your phone restarts on its own after the forced reset, Excellent! No big deal. If not, we carry on.

Step 2: Disable Background App Refresh

Background App refresh might be draining your battery and making your phone active even when not in use.  Your phone will be working harder than it should and won’t have adequate down-time to cool off.  It may help you to disable Background App Refresh in the settings:

Go to Settings > General > Background App Refresh. Tap Background App Refresh > Off to turn Background App Refresh off completely.

STEP 3: Disable Airdrop and Bluetooth

Turning off these features may reduce overheating because they place a strain on the processor and they are always active.  To disable:

Go to Settings > General >AirDrop and select AirDrop turned off

STEP 4: Upgrade iOS

Sometimes upgrading to the latest iOS release can fix this problem automatically without you having to do anything.  Check your iOS version and see if there’s a new update available.

STEP 5: Exit all open applications

Closing unused apps lessens the demand on the processor and may improve device cooling.  Close everything that is open to see if it lessens the load on your phone.

Step 6: Review battery life and uninstall battery-hungry applications

Overheating can be reduced by locating and deleting apps that use the battery unnecessarily.

Go to Settings > Battery. Information about your battery usage and activity appears for the last 24 hours and up to the last 10 days. Insights and suggestions: You might see insights about conditions or usage patterns that cause iPhone to consume energy. You might also see suggestions for lowering energy consumption.


The device’s settings can be reset to fix a number of issues, including overheating.

STEP 8: Reinstall iOS (No Data Loss)

The iOS system can be repaired and reinstalled, resolving overheating concerns, by using a utility like UltFone iOS System Repair.  https://www.ultfone.com/ios-system-repair.html

STEP 9: Use iTunes to Factory Reset your iPhone (Data loss)

As a final resort, using iTunes to conduct a factory reset may resolve persistent overheating issues, but data loss will occur.  This would basically restore your phone’s OS back to the factory condition.

If none of the above solutions work, you should take your phone to an iPhone repair shop like GadgetMates to see if disassembling it and inspecting its internal components might reveal any information about the problem.
