iOS 18.2 Heating issues and battery drain

Do you all face the same issues as I do? Here it is:

I’ve installed the new version of iOS(18.2) and i’m struggling with a few issues:

1- Overheating a lot overheating only when i tried to use the new Ai features like GenMoji and Playground app , I just wanted to try out these features.

2- Extremely battery drain , again related to the new Ai features.

My question is why is this happening ?

For me, iPhone 14 Pro Max, updated and while on a wireless charger within 5 minutes stopped charging and it noted that it would continue when it cooled down. It was extremely hot.


When on a charger, it slowly drained. I checked what was using my battery and it had a mile tracker app running in the background, and it was at 99% of the batteries usage. Not used the app for quite a while so I deleted it and it seems to be charging again now.

things I’ve tried

  • hard reset of iPhone
  • complete reset of iPhone ( erased all data and started from fresh
  • deleting every app
  • background app refresh all off
  • location services off
  • dark mode
  • changed battery 3 times and tested battery capacity with usb tester ( also swapped it with my gfs iPhone 12 battery that lasts her 2 days just to be super sure )
  • i charged phone to 80% , turned phone off and left it off overnight to check if battery is losing charge internally by itself ( it wasn’t)
  • iPhone 12 so no apple intelligence to disable
  • putting it in airplane mode for a long period
  • iPhone in low power mode
