I have read through all posts and want to offer my 2 cents
My iphone 11 pro was normal until I started using the keynote app. It heated up real fast to a point that it is uncomfortably hot (within 1 min). Whenever I switch to other apps, the phone starts to cool. If I switch keynote on, phone starts cooking again. That’s obviously very weird, then I found this thread.
So following the discussion, I made sure my iOS is up to date on 13.1.1. Then I checked my “battery” tab in the settings, 10 min of using keynote consumed 15% battery, while the whole day of using other apps only make up 85%. Keynote is essential to me in my job, so deleting it is not an option. I also didn’t want to “reset all settings”. Instead, I closed settings>general>background app refresh. That totally fixed the problem
To sum up, here is what you can do if your phone is heating up abnormally
- make sure it’s running the latest iOS
- check which app consumed the most energy under settings>battery>battery usage by app, delete the problematic app if it’s not essential
- close the “background refresh” of that app (check other battery saving tips online, it could be other tricks)
- if none of the above worked, reset all setting (settings>general>reset>reset all settings)
- still no luck, contact apple for replacement
