Battery drain again

over 1 year ago

Hi,

why is it so difficult to design a device that simply works, reliably works

For no obvious reason my 255M lost 15% battery over night despite being in Power Saver and Flight Mode next to the bed on the drawer.

Now in the morning, despite still being in Power Saver and Flight Mode it lost 20% during 1hour

Why? No custom Watchface, no using, just in power saving on my arm.

    I imagine this is somehow related to the extra features (wifi) of the 255M...

    I had a bad week with time for very few activities. My FR255 is at 72% battery after 6 days of full-time wear with about two hours of "automatic" GPS activity, which I think is a multiband mode?

    Edit: I forgot to say I am on firmware 16.19, and also I leave the phone connection toggled off almost all the time.

    If it suddenly uses more power, it is probably stuck in some kind of loop, trying to reach something. We have seen it before when the watch is stuck searing for sensors, headphone or even the Connect app on the phone after trying to change watch settings. My first idea would be to restart the watch.

    Guys, all granted. But why would my watch being in Power Save and in Flight Mode search for anything? This combination of power saving and cutting of all connection is supposed to be the least energy consuming active regime... if the watch searches for anything in this situation it is clearly a design/firmware flaw ... in if so many.

    Hi. Just bought the watch a couple of days ago. I noticed this sudden overnight drainage this morning. The watch was charged to 100% during the day yesterday (so I must have had over 80% in the evening)  only to see that the battery is 35% in the morning. I read about similar problems but they were posted a year or so ago. I would have thought that Garmin fixed the problem by now.

    Most of the time when Garmin owners have battery issues, it is not a general issue for everyone, but certain watches that have got themselves stuck into some unfortunate loop of some kind. It typically happens durning upgrades. Most of these issues are fixed by restarts.

    again 20% gone over night despite power saving and flight mode.

    For now, my problem was solved by a restart. We’ll have to wait and see if it comes up again.

    I restart regularly and still this happens. It seems to be connected to workouts. I have not done a workout bow for a couple of days: The watch lost barely 2% per day. Then yesterday evening I did a workout, put the watch in power saver and flight mode afterwards.... but still it lost 20%. So obviously the watch seems to have worked on. I should have restarted maybe. 

    But still, overall: crappy job by Garmin.
