iPhone overheating

Recently, several reports have emerged, and many users have complained about overheating problems with the iPhone 15 series.

While the overheating issues were fixed for most iPhone 15 users, some claim that their iPhone 15 tends to overheat even after installing the update. For instance, one user started having overheating issues until after he updated his iPhone 15 Pro Max to iOS 17.0.3.

Also, some claimed screen burn issues due to overheating, and many have experienced this issue specifically while using the camera or charging. So, if you’re one among those who have faced issues after updating to iOS 17.0.3, continue reading to find the potential cause and the fix.

Why do iPhones overheat?

  • Intensive app or game usage
  • Background processes and multitasking
  • Environmental factors, such as high ambient temperature
  • Battery issues, like degradation or excessive charging
  • Software bugs or glitches
  • Resource-intensive tasks, such as video streaming or rendering
  • Overloaded CPU and GPU

  • Keep your iPhone out of direct sunlight, and don’t block the heat dissipation areas

  • Avoid overcharging your iPhone and use compatible adapters
  • Remove the phone case while charging to dissipate heat
  • Use Wi-Fi instead of cellular data for data-heavy tasks
  • Uninstall unoptimized third-party apps

If none of the precautions help fix the issue, follow the below fixes, which involve modifying a few settings, updating, and resetting the iPhone. Unfortunately, if that doesn’t help either, we have a secret solution up our sleeve; please keep reading to find it out.

Advanced tips to stop your iPhone from overheating

Disable background app refresh

Optimizing your iPhone’s performance and preventing overheating can be achieved through various settings and controls. One critical aspect to consider is the Background App Refresh feature.


This feature allows apps to update their content in the background, but it can also consume unnecessary resources and contribute to your device’s temperature rise. Hence, here are steps on how to disable it:

  1. Open the Settings on your iPhone, and once loaded, navigate to General and tap on it.
  2. Once you’re in, you will find several settings, so look carefully for Background App Refresh.
  3. Check the apps enabled in Background App Refresh and disable it for the apps that you believe consume a lot of resources, or turn off the feature entirely.

Turn off location services

Location services, primarily reliant on GPS, often lead to substantial energy consumption, resulting in increased heat generation. To mitigate this issue and conserve battery life while reducing heat emissions, follow the steps below:


  1. Access your iPhone’s Settings and proceed to Privacy.
  2. Within the Privacy menu, locate and tap on Location Services.
  3. To reduce heat generation, switch off the Location Services feature and use it when needed.

Update iPhone to the latest iOS version

It is important to update the iPhone to the latest iOS version, as it addresses the bugs and provides the fixes. If you’re on older iPhones, we suggest you wait and check the forums for fellow iPhone users using the same model as yours to put out their experience so you can proceed with the update.

However, suppose you’re an iPhone 15 user. In that case, it is mandatory to update your iPhone as Apple has officially recognized the heating issue and has released an update, iOS 17.0.3. Follow the below steps to download and install it:


  1. Start by launching the Settings app on your iPhone from the homescreen or App Library.
  2. Once you’re in settings, scroll down and tap on General and then Software Update.
  3. If an update is available, tap on Download and Install.
  4. Once the process is done, your iPhone asks for a passcode to reboot, and the update will be applied during the restart.

While Apple is actively working on software updates to address the overheating issue, iOS 17.0.3 was a step in the right direction.

However, for those facing the issue, wait longer as more updates are expected to follow. Hence, we suggest you keep your iPhones up-to-date to get rid of the heating issue.

Factory reset iPhone

Resetting your iPhone can be a powerful remedy for addressing overheating issues. It clears out unnecessary processes and restores your device to a fresh state, often resolving heat-related problems. Here are straightforward steps for resetting your iPhone:

  1. Open the Settings app and scroll down, tap General, and then Reset.
  2. To reset all settings, tap Reset All Settings. This will erase your customized settings without deleting your data.
  3. For a complete factory reset, tap Erase All Content and Settings. This option will erase all your data, returning your iPhone to its original state.
  4. Remember to back up your data before choosing the second option, as it will wipe everything from your device.
