Here, in this article, we have discussed the simplest and straightforward methods to Fix Overheating Issues in iPhone 8 or 8 Plus.

When an iOS device heats up and becomes noticeably warm, heat is just escaping from the interior components, which may be a good thing. That being said, the ARM chips utilized within these devices are remarkably efficient in the amount of warmth they produce. They only become noticeably warm when being overworked for a big amount of your time.

iPhones are designed to work between 32 F (0C) and 95 F (35C). If you’re living during a place that gets warmer than 95 F, your iPhone may get too hot. Further, your iPhone may display a warning message if you set it during a warm environment. For example, if you allow your device during a car on a hot day, your iPhone may show this message: “iPhone must calm down before you’ll use it.” Just close up your device and place it during a cooler place. this enables your device to chill down and perform normally again.

The first troubleshooting step that you want to do is restart your iPhone. This may seem simple to you but a lot of minor bugs and app issues are fixed by just turning a device off for a few seconds.

  • Press and hold the Top (or Side) button until the slider appears.
  • Drag the slider to turn your device completely off.
  • After the device turns off, press and hold the Top (or Side) button again until you see the Apple logo.

A soft reset or forced restart should be able to deal with it. Here’s how it’s done:

  • Press and quickly release the Volume Up button.
  • Press and quickly release the Volume Down button.
  • Press and hold the Side/Power button until the Apple logo appears.

Toggle Airplane Mode

Another simple yet very effective solution to random errors is the Airplane Mode trick. It works by simultaneously restarting the phone’s wireless system and thereby eliminates random errors. Here’s how it’s done:

  • Tap to open the Settings app from the Home screen.
  • Scroll to and tap on the Airplane Mode menu.
  • Tap the Airplane mode switch to turn it on. Doing so will disable your iPhone’s wireless radios as well as its Wi-Fi features.
  • While the Airplane mode is enabled, perform a soft reset on your phone.
  • Once the phone is finished booting up, go back to Settings-> Airplane mode then toggle the switch to disable the feature.

Enable Wi-Fi and reconnect to your Wi-Fi network afterward and see if the problem is fixed.

Remove iPhone Case

Many people use a case to protect the iPhone from damage, but it also prevents heat radiation. So if your iPhone is hot and you are using a case, remove it to cool down your iPhone 8 or 8 Plus.

Disable Network Services

If you are using your iPhone in areas with weak or poor network coverage, then you might as well consider disabling its network features to save battery and prevent overheating problem to occur. In cases like this, you can enable Airplane mode to temporarily disable other iPhone features that require network connectivity including Bluetooth, GPS, Wi-Fi, and Cellular Data.

Use Low Battery Mode

If your battery status is low and your iPhone 11 is overheating, you can adjust your battery settings to low power mode. Less power consumption will generate less heat in your device.

To enable low power mode, simply navigate to Settings > Battery > Low Power Mode and slide the bar to enable this mode.

Disable Unwanted Background Applications

The Battery Usage feature allows you to see which apps eat a lot of battery life and cause the iPhone overheating issue. Simply go to Settings, tap on Battery, and check the Battery Usage. Then you can see the most power-consuming apps, just go back to the Home screen to close or remove them.

Check for Software Update

Most likely, Apple is already aware of the problem and working on a fix without giving out any official statement. Assuming that it’s indeed a software issue, the official fix will likely be entrenched into the new firmware update that’s rolled out next so you better not miss it.

  • Open the Settings app from the home screen.
  • Tap General.
  • Tap Software Update.
  • If there is an update available, follow the onscreen instructions to install the updates on your iPhone.

Perform Factory Reset

Last but not the least, you can reset your iPhone settings and data completely to run your device in the default settings.

  • Go to the iPhone Settings > General > Reset.
  • Select Erase All Contents and Settings > choose Erase Now.
  • You have to enter the passcode if prompted.
  • Tap on Erase iPhone.
  • Then tap on Erase iPhone again to continue the action.
  • If prompted, enter your Apple ID and password.
  • Then tap on Erase to continue.
  • Wait for it and it will reboot your iPhone.

Restore your iPhone in iTunes via Recovery Mode

It’s an advanced type of iOS restore you can do when dealing with more intricate system errors that caused a device to malfunction. In this case, you will need to put your iPhone in a recovery mode state first and then restore iOS in iTunes.

  • Press and quickly release the Volume Up button.
  • Press and quickly release the Volume Down button.
  • Press and hold the Side/Power button when you see the Connect to iTunes screen. Do not release the buttons when you see the Apple logo since you’ll need to enter recovery mode.
  • On the next screen, you should see the option to Restore or Update.
  • Select Update first to update iOS. Otherwise, select the option to Restore.

Wait for iTunes to attempt to reinstall iOS without erasing your data. iTunes then downloads the software for your device. If the download takes more than 15 minutes, your iPhone exits the Connect to iTunes screen. If this happens, wait until the download is finished then go back to the previous steps to enter recovery mode again.

Restore your iPhone in iTunes via DFU mode

It’s regarded as the deepest type of system restore you can do on your iPhone. It allows your device to communicate with iTunes on a computer without loading the operating system or bootloader

Here’s how to perform a DFU mode restore on your iPhone 8:

  • Close any running programs on your computer.
  • Connect your iPhone to your computer using the Apple-supplied USB connector or Lightning cable.
  • While your phone is connected, press and hold the Side/Power button for about 3 seconds.
  • Keep pressing on the Side/Power button then press and hold the Volume Down button for about 10 seconds. If the Apple logo appears, it means you’ve held the buttons too long and that you’ll have to start all over again.
  • If you see no logo, release the Side/Power button but keep holding the Volume Down button for another 5 seconds.
  • If the screen stays black afterward, it means that you have successfully entered DFU mode. At this point, you will be prompted with an alert message on your computer saying that iTunes has detected your iPhone. If you see that message, follow the onscreen prompts to complete the DFU mode recovery process.
  • If you see the Plug into iTunes screen, it means you haven’t entered DFU mode and that you will need to start all over again.

If none of that works, then most likely what you’re dealing with is a hardware problem.
