After the iOS 16.4.1 update my iPhone battery health went down
I have an iPhone XR that is about 4 years old. Realizing updated versions are out there, this one was expensive but new ones are even more expensive. After the 16.4.1 update, my battery simply just started dying? Until then I could go about a day and a half. now lucky to get 8 hours out of it. Any ideas? I called apple support and was told the update was supposed to fix a bug???
