There are several reports in the community of other members experiencing the same issue. It’s a possible bug, but better to error on the side of caution and get your device properly diagnosed.


Please have Apple perform diagnostics on your iPhone. It can be done in person at an Apple Retail Store or at an Apple Authorized Service Provider. You can also contact Apple Support and request remote diagnostics.

Welcome and thank you for reaching out. 🤗


It is normal for an iPhone to run warmer than usual for a day or two after a major iOS update due to background processes like indexing.


However, if the issue persists, there are several steps you can take to resolve it:

  • Wait it out — Background tasks like photo indexing and data syncing can cause the phone to heat up temporarily after an update.
  • Update your apps — Third-party apps may need updates to run efficiently on the new iOS version. Check the App Store for any available updates.
  • Check your charger — Using a high-wattage charger can cause the phone to heat up. Try using a standard 20W charger or a different power source.
  • Remove the case — Some cases can trap heat and prevent the phone from cooling down properly.
  • Enable Low Power Mode — This reduces background activity and can help lower the iPhone’s temperature.


If your iPhone continues to overheat, you may want to contact Apple Support for further assistance.


Good Luck! 👋🏼😉
