Anyone experiencing high battery drain should start with a hard reset (holding the power button for up to 15 seconds). If this does not resolve the issue, more information will likely be needed from you…

hello Former Member,

what i can tell for sure is that currently (with only spo2 activated during night and daily steps tracking) the battery life of the 945 is way worse compared to the 935. with 1-2 workouts…

Can't we have statement from Garmin if they have noted that there is an issue with battery drain and they plan to solve it?

i just charged my 945 yesterday evening. unplugged it at ~21.45. didn't wear it til 6AM, now at 1:30PM i'm already down to 84% without any activity - never had that before 2.80

you tried the hard reset?

0 juh82 over 5 years ago in reply to f|33tStA

yes, twice already, will take a while to see if it helps, but from what i read, it just helps for some hours in several cases.

Former Member sorry, but after 48 hours the battery drain comes back, again 14% a day instead of arround 7% a day, seems the hard reset fix only the first 24 hours

Same here and alarms didn't work this morning for the first time (never problem before the hard reset).

I'm a bit dissapointed with the watch...
I used Fenix 5s for two years and changed to F945 mainly because of the battery
It turned out that my old fenix's battery was the same as this new watch...
I have to charge f945 every 5/6 day (ohr, bluetooth on + 3 short gps activities)
Sad...

you have any idea what we can do, will there come a beta or something similar as for FR245 (seems the beta fixed the battery drain there)?

Same here, it worked pretty well for a while concerning battery consumption but suddenly it's much bigger without changing anything

Just to "prove" the opposite: went on a run today with a fully charged 945 and had music streaming. It took 15% battery during the 1h 15min run which I think is a very good value. After my sudden battery drain and subsequent hard reset, the watch is behaving very nice.
