My battery is lasting barely half of what it used to prior to iOS 15.4.1. Overnight, without any apps running, and all background refresh off, my battery dropped from 98% to 55%. Before, it would drop, maybe, 5%.
iPhone 12
Thank you. I will be extremely annoyed if this actually works.
I've had the same battery-drain problem since updating my iPhone 11 to 15.4.1. When will Apple issue an update to fix this problem?
We have no way of knowing, maybe you should ask Apple. This is a user to user forum.
