iPhone 15 not charging after update; unrecognized battery

My iPhone 15 has been fine until the update. It’s my daughter’s phone and it’s always low battery. It charged just fine until recently to where it won’t read any charging cables. I did see the message pop up and say Apple don’t recognize the battery. It’s never been worked on at all. How do I get the phone to hold a charge so I can update the phone? Thank you!

iPhone 17 Pro Max, iOS 26

Everything that you are telling us indicates that the battery is failing.


Make an appointment at the Apple Store / Genius Bar or take the phone to an authorized Apple service shop to have the battery replaced. About $100 (U.S.)
