battery issues after ios 26.2 on iPhone 13

after I updated my iPhone 13 to iOS 26.2 it is constantly restarting and showing the battery with different levels of charge everytime it restarts. It Goes from 90% down to 10% in a matter of 3 minutes. Only stops restarting when connected to energy. Anyone else experiencing the same?

Your battery is failing. Contact Apple Support for info on how to have it replaced.

Fix the Boot Loop:

Being you can get into it, I'm not so certain it is in a Boot Loop. So, see if you can get out of it. If that does not work, then clear your caches. Caches are created for remembrance of app usage (i.e. power) so that they open more affectively, and in a more productive state. If your iPhone is just restarting after an update, then it is undoubtedly suck in a Boot Loop. Use my User Tip for That: How to Fix an iPhone in a Boot Loo - User Tip

Clear the Caches:

Being it stops restarting when connected to energy, clear your caches. Use my User Tip for That: How to Clear "System Data" in your iPhone's Storage: - User Tip
