Last Updated Dec 18, 2022

If you’ve noticed that your iPhone gets hot while charging, it’s generally a mild issue that you can easily fix with a simple change. However, this can sometimes indicate a bigger problem, such as the battery going bad. 

Read on to learn ten tips and tricks for keeping your iPhone from overheating. These tips will help keep the iPhone from reaching a temperature that could cause irreversible damage. 

Remove the Case When Charging 

If you have a case on your iPhone, it’s very likely the cause of your phone getting hot while it’s connected to the charger. 

It’s normal for your phone to be slightly warm to the touch when it’s charging. However, some cases may not allow this heat to escape. This leaves heat trapped between the case and your phone, which could cause your phone to overheat. 

The best way to prevent this is to remove your case while charging your device. 

Try a Different Charger

It may also cause your phone to overheat if you’re charging it with a charger that is not an official Apple charger. To test the theory, try using an Apple charger instead. 

Consider purchasing a replacement if your original charger has been lost or damaged. Having the correct charger will prevent overheating and potential damage to the battery. 

Now, let’s see the next fix.

Avoid Using Your Phone While it is Charging 

You’ve likely noticed that the temperature of your phone gets warmer when you use it for an extended period. 

This heat comes from the CPU constantly running within the device. When you combine this heat with the heat from charging the battery, you’ll notice that the temperature is much warmer and sometimes even hot. 

Because of this, it’s best to avoid using your phone while it’s charging, especially if you’re already having an issue while charging the device. 

Keep Apps from Running in the Background

The same principle applies if several apps are running in the background while charging your device. Like when you’re actively using the phone, the CPU will heat up while running apps in the background. 

To keep your apps from running in the background, you’ll need to do the following:

  1. Open the settings on your iPhone.
  2. Tap General.
  3. Tap Background App Refresh.
  4. Disable the option to allow apps to refresh in the background.

After you’ve disabled this setting, it’s best to close all your open apps. You can do this by swiping up and to the right in one fluid movement, then swiping up to close any open apps. 

Put Your iPhone in Airplane Mode to Charge 

If you don’t want to disable the setting that allows your apps to refresh in the background, you can put the iPhone in Airplane Mode while it’s charging. 

Putting your phone in Airplane Mode provides a temporary way of stopping the apps from refreshing while it’s on the charger. 

After you unplug your phone, you can disable Airplane Mode, and your apps will continue to update in the background as usual. 

Keep Your Software Updated 

If you don’t keep your software updated, it can cause various problems with your iPhone, including overheating while it’s charging. This is because your device lacks specific bug fixes that are likely included in the latest update. 

You can update your iPhone’s software by following the steps below:

  1. Open the Settings. 
  2. Select General
  3. Tap Software Update
  4. Allow your device to search for the latest update.
  5. Tap Download and Install. 

Once you’ve completed these steps, your phone will reboot. When it comes back on, it’s a good idea to ensure all the apps are up to date because outdated app versions can cause the issue. 

Restore the Factory Settings 

The overheating could also be related to the settings on your device. Since it’s near impossible to figure out exactly which setting is the cause, the best option is to restore the factory settings. 

You can do this by going to: 

  1. Settings
  2. Transfer or Reset iPhone
  3. Reset
  4. Reset All Settings

Now, let’s see how to factory reset your iPhone below.

Factory Reset Your iPhone

If resetting the settings doesn’t work, your best option is a factory reset. This will erase everything from the phone and restore all settings to their factory default. 

If you need help factory resetting your iPhone, follow these steps:

  1. Go to Settings
  2. Go to General
  3. Tap Transfer or Reset
  4. Tap Erase All Content and Settings

Once your phone completes a reboot, you should be able to charge it without it overheating. 

Replace the Battery

If you’ve tried all of the possible solutions and your iPhone continues to overheat while charging, it may happen because the battery is going bad. Unfortunately, the battery will need to be replaced to fix the issue. 


Remember that self repairs yourself will likely void any warranty you have on the phone. To avoid voiding your warranty, you should contact Apple for assistance.

Now you know everything about why your iPhone may be getting hot while charging and how to fix it.
