Should this be the case, you may refer to this post for potential solutions. Read on to find out what causes your new iPhone to overheat and what must be done on your end to fix the problem?

Overheating problems in mobile devices are generally attributed to three main factors including software issue, hardware damage, and environmental factors. Software-related overheating problems are typically transpiring within the system like when faulty new apps or software updates are installed. Hardware-related overheating issues are apparently those that occurred due to bad hardware components like a defective battery. Finally, environmental factors range from the ambient temperature or location where the device is placed. Apple normally designed their iPhones to work in temperatures between 0 and 35 degree Celsius. That said, using the iPhone beyond 35 degrees centigrade will likely cause it to get warmer than usual and possibly the underlying cause for an iPhone overheating problem. Otherwise, it could be the rest of other possible triggers.

Potential solutions to fix iPhone 8 Plus overheating problem

The following solutions are used to deal with overheating problem triggered by software glitches and errors. Try these methods to rule software problems from the possible triggers before you proceed to applying hardware problem fixes.

First method: Quit background apps.

While keeping apps open or running in the background is recommended is beneficial for multitasking purposes, any of these background apps can crash, get rogue and trigger the iPhone processor to work relentlessly. For starters, follow these steps to force close apps on your iPhone 8 Plus:

  1. Double-tap the Home button. Doing so will show your most recently used apps.
  2. Swipe right or left to switch between apps previews.
  3. Then swipe up on an app’s preview to close the app.
  4. Follow the same process until all apps are closed.

After quitting all your background apps, restart your iPhone 8 Plus or do a soft reset by pressing the Side/Power button until the Slide to Power off appears. Drag the slider to power off the iPhone completely. After 30 seconds press the Side/Power button again until the device power cycles.

Second method: Locate and remove frequently crashing apps.

Your iPhone integrates a menu wherein you can find logs of data and file crashes. Referring to these logs will give you a hint on which from your apps is not performing stable or keeps crashing. There is a higher chance that some rogue apps are causing your iPhone processor to be revved up to a hundred percent. The apps that appeared more often in the diagnostics and data logs are likely the culprits.

To view and access this menu on your iPhone 8 Plus, head over to Settings-> Privacy-> Diagnostics and Usage-> Diagnostics and Data.

You’ll see a bunch of apps and data logs on the next screen. Try to scrutinize which among apps, is appearing repeatedly more often, like around 10 to 20 times a day. If you see any app with the said frequency logs, then that is  more likely at fault. As resolution, you can try clearing disable or uninstall the app from your device completely.

Third method: Reset all settings.

Resetting all settings will rule out incorrect power settings from the possible trigger. This reset is different from a factory reset. What it does is to remove and all of your preferences for Wi-Fi, Bluetooth, DND, Brightness and Wallpaper, Privacy and Sounds and restores them to factory defaults. All these are carried out without deleting any of your data stored  in the phone’s internal memory. That said, you don’t have to worry about losing any personal information even if you’re prompted with warnings before confirming action. Here’s how it’s done:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Tap Reset.
  4. Select the option to Reset All Settings.
  5. If prompted, enter the correct passcode for your device.
  6. Tap Reset All Settings to confirm.

Wait for a few minutes for the reset to complete. Your iPhone then reboots when the reset is finished. Consider performing all settings reset if your iPhone started to overheat after making changes to some settings.

Fourth method: Update iOS to the latest version.

Installing the latest software update on your device will not only add new features and enhanced your device functions but also offer fixes to certain bugs. Hence it could be the key to fixing bug-inflicted overheating problem on your iPhone 8 Plus. Here’s how to check for and install new software update for your iPhone:

Navigate to Settings-> General-> Software Updates menu.

If an update is available, you will be prompted with an update notification. Create a backup of all your important information then proceed with the update download and installation if everything is set.


Fifth method: Factory reset or iOS restore.

You may opt for a full system reset or restore your iPhone 8 Plus to factory defaults if the problem persists up to this point. It’s is however worth to note that this is going to be a tedious job as it involves backing up data before the reset and setting up the iPhone afterwards. Nonetheless it may still be worth a shot especially if you’re certain that the overheating problem is attributed to software bugs and glitches. Should you wish to proceed, you can do a full system reset through your iPhone Settings menu or using iTunes.

If the overheating problem instigated after installing a new software update, it’s possible that the update contains a bug that triggers your iPhone processor to work continually and eventually caused the device to get hotter or overheat.

Other Helpful Tips

  • Cool down. Giving your iPhone ample time to cool down is actually the first recommended workaround that you should do if you noticed your device is starting to get warmer. It’s normal your iPhone to become warmer with prolonged use like when playing mobile games or streaming videos.
  • Remove any cover/protective casing. Some iPhone cases especially non-Apple made aren’t actually fit with your device. Some are too tight while others a little loose. There also some that can somehow fit but not may hinder some of the iPhone’s physical components without you noticing. As a result, your device may not be able to vent or excrete the heat and so eventually overheats.
  • Don’t leave your phone in the car. The temperature inside the car is apparently hotter than outside. Thus it’s very likely for your iPhone to become warmer when left inside the car for a longer period of time.
  • Use only Apple charging equipment. While it’s normal for your iPhone to heat up while charging, some non-OEM chargers don’t meet with your iPhone’s power input/output requirements. This will likely cause some conflicts and overheating could be one of the symptoms.

If none of the aforementioned solutions and tips helps and your iPhone 8 Plus is still overheating, then at this point, you should consider opting for service. The overheating problem you’re dealing with could be a hardware problem that needs some fixing. You may contact Apple Support for other options. Otherwise, visit the nearest Apple Genius bar in your place.
