I have sent an error report on this but thought I should post as well. I am seeing poor battery life on the beta on this first full day of use.
First some background. I installed the beta yesterday and had the issue of continuous reboots. I tried clearing device cache but ended up having to do a full reset and restore from a backup. Since the reset/restore the watch has seemed fine. I typically charge my watch in the morning so I started with a full charge this morning at roughly 7am. By noon I was down to 38% and now at 1pm down to 32%. This is much worse than prior to the beta and I really have not changed my usage or settings, beyond turning on the new gestures.
So I have to join the chorus of people reporting definitely poorer battery life compared to before beta. Almost dare to say battery depletes about twice as fast or just below twice.
I have noticed a significant battery drain that occurs when I'm sleeping and the play store turns on my wifi when I open it which is a huge power hog when compared to the Bluetooth. The increased battery drain when sleeping isn't all that surprising considering how many things they're trying to keep track of. I wonder if movement when sleeping turns on the screen as well. I will turn off AOD tonight to see if there is a difference.
I updated to the second beta and while the battery life is slightly better, it is still worse than pre-beta. I have tried disabling some features to improve and turning down the brightness but still need to charge twice a day. I give it a full recharge in the morning and then just a bit before going to sleep to make sure it lasts through the night.
