after the update 13.5.1 my battery drains because certain apps run in the background 24 hours a day. after removing the app, it is solved for a while, but the next app takes over this behavior again ??
iPhone SE, iOS 13
Before updating to the latest iOS 13.5.1 as told on your post what was your earlier iOS version. Then you can look into the iOS changes that has happened between the earlier version on your iPhone and this new version that you have updated now.
This will give you a broader idea of the issue, if it is directly linked to the iOS version or is triggered by something else.
Because iOS 13.5.1 was only for security update, you may probably be carrying a legacy issues.
