User level: Level 6 (10,782 points)After upgrading to 27.2 on my iPhone yesterday my Apple Watch Ultra has very poor battery life. The watch is on 26.6 as it does not support 27. I think the issue relates to background app refresh.
The watch was at 100% at 10am, but had dropped to 88% by 11am. By 12:30pm it was down to 78%. I turned off all background app refresh and the fast battery drop stopped and it was still at 56% by the time I went to bed 12 hours later.
Is anyone else seeing this issue with iOS 27.2 and WatchOS 26.6?

Are you using the original Apple Watch Ultra, since it is not upgraded to watchOS 27?
Force restarting your watch would be the first thing to try to stop the battery drain. Press and hold the Digital Crown and the Side button together for about 10sec, until the Apple logo comes up again.
If this does not stop the battery drain, unpair the watch and connect it again to your iPhone, this helped users in the past.
Unpair and erase your Apple Watch - Apple Support
Also restart your iPhone, just to be sure:

Haha. Wow. A restart? Rocket science. Thanks?
