Q: upgrade 9.3.2 over heating

Hello fsldubai143,

Thanks for that info and choosing the Apple Support Communities. I know that having your phone not work properly after updating is not what you expect.

The following articles will be helpful in troubleshooting your issue, including restarting, adjusting battery settings, and possibly backing up and restoring the phone software.

1. Restart your iPhone, iPad, or iPod touch

2. Temporarily turn off settings like Background App Refresh and Location Services and test your issues, as this article on batteries and Apple devices suggests:

Batteries - Maximizing Performance - Apple

3. Make a backup of your personal data and restore the the iPhone back to factory settings, as this can narrow down a hardware or software issue.

How to back up your iPhone, iPad, and iPod touch

Import photos and videos from your iPhone, iPad, or iPod touch

Use iTunes on your Mac or PC to restore your iPhone, iPad, or iPod to factory settings

Cheers!

Thanks for the reply, that info really helps. If you used iTunes to restore your iPhone's software and tested the issue with the iPhone setup as new, as mentioned in the last step, then you would need to get your iPhone serviced by an Apple repair tech. You can click this link to see your options.
