iOS 15 Home app and HomeKit have excessive battery drain

After upgrading to iOS 15, I noticed excessive battery usage caused by the Home app. In the battery usage in settings, it says “accessories” under the home app activity.


I see similar behavior on iPhones and my iPad.


In terms of my HomeKit setup, I have several Phillips hue lights, a Kwikset lock, a temp/humidity sensor and 4 cameras configured as HomeKit secure video. I also have an Apple TV HD that serves as my HomeKit hub.


I am not sure what’s causing this battery usage as it didn’t exist in ios14. I am also not sure how to isolate the guilty accessory.


One theory is to blame on device processing for all the cameras such as activity detection. Not sure if that happens in the hub or in the devices.

So more details. I turned off all notifications from every device (cameras, door bells, locks, etc) in the Home app. Home App > Home icon > home settings. I also turned off all face recognition. I did leave the iOS level Home app notification on.


This helped to (almost) completely eliminate Home battery usage.
