  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.

Fourth solution: Reset all settings on your iPhone XS.

Your iPhone settings can be customized based on your preferences. However, applying an invalid settings modification can also cause adverse symptoms. If your iPhone started to overheat after making some changes to your settings, then that could be the underlying cause of the problem. If you still can recall which options and settings were changed and how they were changed, then you can just revert them back to their previous configurations. But if that’s not possible, you can reset all settings instead. Unlike a master reset or factory reset, this process does not affect any saved data on the internal memory of your device, therefore you wouldn’t lose personal information. Here’s how it’s done:

  1. Tap on Settings from the Home screen.
  2. Select General.
  3. Scroll to and tap on Reset.
  4. Select the option to Reset all settings.
