v11.25/v11.28: Is battery drain back?

I apologize for addressing again this problem, but I may need some help: I'm in the beta program and I was on 11.25 beta until today when I decided to charge my watch and it updated to 11.25. I had a great long period before this and I was surprised at the very low drain on my battery (4-5% daily). Now, after the update via Garmin express, I noticed that the battery is running super fast! Approximately 1% per hour. I did, as I usually do lately, restart the watch after the update via a hard reset.

Any suggestion short of factory resetting?

Thanks

Gianluca

PS: I should point out that, during installation, I had some problems. The watch would loose connection (using original cable) and it stopped at 83% for a long time. I interrupted the process and Garmin express reported that the update had been successful
