Increased battery drain with 27.09

Yes

Yes, Same here. I was was worried about my Device until  i read this post. 
@garmin, anything  you can Check and Improve her please? 

I did get the newest update pushed yesterday and noticed significantly better battery  life, returning to normal/

Great News, thx. What is your Version Now?! 

As always, restart the watch.  Usually fixes battery drain issues.  Most of the time they happen for me after the GPS is on and then seemingly stays on even though the activity has concluded. The same thing happens when using GPS to get current atltitude.

I will try that. My FR265 was in the high nineties when I went to bed and eighty-one when I woke up. 

Forerunner 255
After update to 27.09 battery was drained empty within one day. After restarting the watch battery life is now about 4 days.
Before update it was 10-12 days...

Hallo, same issue. Since today. 6% in 1hour. Whats that???

Same here.
The only thing i changed in my habits is due to an injury i do not [RUN] anymore, just [ELLIPTICAL] and [INDOOR CYCLING]. Just saying.

Restarted it, too.

In case it is not clear, please do a forced restart by doing a long press on power button and not the regular shutdown. See if that helps.
