Night Battery Drain

4605486 over 1 year ago

I have the Problem, that my watch drops 15-20% Battery over Night while wearing it to sleep.

Espeacially if my Battery hits 35-40% then almost every time i wake up the next morning with 15-20% less.

Like today i lost around 15% Battery over Night.

I tried soft reset and complete reset of the watch.

This Problem occoured already more then 5 times and especially if i hit 15-40% Battery capacity.

Oxygen saturation is always on demand. No activity is tracked between the Period of Battery drain at Night .

Is there some Solution or is this a Software bug or Hardware defect?

I an the owner of the post. Try to charge your watch a 100%, and try to sleep without airplane mode and Bluetooth on (I know I don’t like too but I’m doing some test)

for the moment it’s works…

try to turn off Oxygen saturation

Oxygen saturation is on demand I am not using this feature at all.

It's Always disabled.

this is normal because the watch can work normally even with 1% battery capacity in smartwatch mode

Battery drain of 15-20% in 1 night is not Normal for this watch. And not if this happens every time when I hit 35-40%.

This happened already many times.

This doesn't sound normal to me at all. I'd say its either due to the latest firmware or an issue with your unit. Can you contact Garmin support?

I see, thank you I will do that!

Chances are the screen is turning on throughout the night.

Sleep mode is helpful. But if you look into the DND menu on connect you'll see an option to turn off gestures. DND can be set to turn on when sleep mode is active.

Sleep mode is enabled before sleep with DND. Turn off gestures as well.

All this functions are like you described.

Contact Garmin - it's unusual behaviour

yeah- if sleep mode is enabled, and you are not doing O2% at night- that's unusually high. Should be no more than a couple %. Might want to contact Garmin on this one.

I guess the other question would be- how much are you losing during the day- with and without AOD (not including gps activities).
