Recently, much shorter battery life

A couple of weeks ago my FR945 went from about 5-6 days of battery to much less than 2. I reset the watch, am sticking with a stock watchface, made sure seconds and SpO2 are off... And battery still stinks. Any ideas?

In my case, I can report that after rebooting the watch, battery drainage seems to be gone.

So if anyone is having this issue after updating to v12.00 and sensor v6.60, try to reboot the watch

My approach was similar. Also restarted it pressing the button for a long time, charged it fully (left it there for 3-4h) and then it went back to normal.

I did not disabled Bluetooth but I have most of…

I have disabled fully the screen light (had it partially before) and rebooted the watch and it looks slightly better 89% after half a day and a couple of activities of around 1h (swimming in a pool and indoor cycling)

However, now it is not syncing the bike activity with garmin connect…

I was having the same issue, rebooted the watch and the issue is now gone. Give it a try

Yeah I got the latest update. I went from 0.3% per hour to 1.5% per hour. From 13 days battery life to 2. Hopefully restarting the watch will fix that. I am hoping to find a way to roll back from the latest update

I restarted the watch but it did not help. Still the same issue. The battery is getting drained extremely quickly.

With bluetooth off and watch on, I pushed buttom on/off for 30 sec. Turned on the watch and charged it to 100%. Now less than 0,25% per hour

Same problem since v12
Charged at 100% around midnight was 90% at 8:00am.

I did not disabled Bluetooth but I have most of the notifications and alarms disabled

My battery went to *** after installing firmware 12. I was having 7% battery drain per hour. I restarted my watch but still same issue. What fixed my issue was resetting the watch and now my battery drain is around 3% per day.
