Battery drain after update for I phone 11

I have an iPhone 11 and downloaded the latest version update which is 26.2.1 to my iOS Apple phone and now my battery is staying dead and will barely take a charge. With Wi-Fi off and Bluetooth off it still is barely charging my phone. It’ll cut off on me. Does anybody know a fix for this?


iPhone 11, iOS 26

If you have the original battery in your phone it likely needed to be replaced some time ago. iPhone 11 was released in 2019, almost 7 years ago. Open Settings > Battery > Battery Health - if it is 80% or lower as I suspect it is, the battery is failing and that had nothing to do with the update. You need to either pay Apple to replace the battery or trade the phone in on a new iPhone.
