Firmware 2.20.28 Battery drain

Brad_Olwin

@dirk-münster I just tested this with one S9P on wrist and one on the desk all night. On wrist from 99% to 91% and on the desk from 99% to 97%. I would definitely try a battery recalibration. This does not seem an issue from my tests. I will keep this running for a bit.

I did a hard reset. I think it helped. 4% at night on a table with sleep monitoring.
The ability to back up the watch settings is very much needed!

There was a new update “2.20.30”. Maybe the issue is already fixed No info about what’s new with this update on the official web page.

@simon
the changes don’t specifically describe the drain as I see it…

Hi,

I have the same issue with 2.20.30

Not sure if it was related to me not wearing the watch, but before the firmware update I could wear it for more than a week, then I noticed that it lost more than 30% in one day without any activity at all from my side. I don’t have sleep tracking enabled.

I have noted down the battery level for today and will see how it evolves over the next days and report back.

Will this be fixed in a new firmware?
Thanks

@thibaut
did you empty the battery, fully charge the watch and then do a 12s soft reset?

Just as a reminder, a couple of days after the last firmware update my S9B got stuck on a black screen, and I had to soft reset it. Not a problem at all (it hasn’t resurfaced) but after the soft reset I experienced tremendous battery drain during the day, but none during night, and also non in battery saving mode (when the watch is on its last %) . Turned out that somehow (probably when I was trying to solve the black screen issue) illumination was set to always on. Sometimes the solution is rather obvious, duh.

big battery drain until 2.20.30 (running 2h with 14% battery down) and no more WHR (because tattooed on both wrists)… unbelievable disaster work in 2022 from suunto.

@set_218
but did it become better with 2.20.30?

@set_218 Sorry, I can’t confirm.

1 week since last charge, with 4 hrs of windsurfing and 3 hrs of running, and the watch is down to 51%

@surfboomerang
similar here… no wind, no surfin… but battery in a 3 year old watch is within reason

@freeheeler

I did not yet do the soft reset. I will do when it reaches 0% then and I charge it to the 100%.
Also the backlight is turned off.

I did go running this afternoon and the battery dropped down 10% for a 1:38 run. I never really paid attention before how much energy a run would take, but it feels much higher than before.

@freeheeler

no. also with the 2.20.30 update the battery status is a disaster. like the first big update years ago on the spartan series.

load the S9P on 99% yesterday 5pm. no sports or activity. just wearing it 24/7 with whr + sleep counter. Now -> 86%

@set_218
and did you empty the battery, fully charge the watch and then do a 12s soft reset?

Set_218

@freeheeler

no… not now. i am reading this solution too late… hope it will work.

freeheeler

@set_218
I’m sure it will

Dimitrios Kanellopoulos

Let it dry out of battery and charge full.

Usually it should waste 20% per day max with backlight on (adaptive) many notifications and all 24/7 tracking on

Consumption per hour of gps + whr should be around 4%

thibaut

Hi,

I wrote before that my backlight was not on, but this was wrong. I just didn’t see it as it was set to low.The update must have changed my backlight settings. I turned the backlight off and the battery usage seems to have returned to normal usage

Thanks everyone for their help
