The new iOS app 1.2.4 has been draining my iPhone SE (new version), It's using 60% of battery power (background). I temporarily turned off background refresh for Hubitat. FYI I'm on the 15.2 beta 4, but the problem only seems to have cropped up when I got the new Hubitat app installed.
Is high accuracy presence turned on? In the past that has killed my battery like nothing else, and so I always leave it turned off.
I turned it off and power cycled the phone. Seems better now. thanks!
