Battery drain

BastMaSVSRS9PP

Yes it has been shared multiple times in this forum but this post has been created in May 2023!!! One and a Half year later the issue still persists. One and a half year!!! I’ve been patiently waiting but the last battery drain event during a trail running / camping trip weekend got me upset

Winter and ski touring and such is coming up. I really want it to work seemingly without fiddling around with soft resets constantly . I love my Suunto it’s a wonderful watch but this is one issue driving me nuts.

@duffman19 I have put my watch on it’s side this week - instead of face down… maybe… less drain?

@larrybbaker Why not just turn off 24/7 wrist HR tracking when you leave the watch on the table?

larrybbaker

@iterumtenta it is off.

@larrybbaker I did a very short experiment, but it is telling none the less. Last night I took my watch off and placed it on its side. Overnight (~8 hours) it lost 0% (91-91%). In the morning, I turned it face down. It lost 6% in less than 3 hours (91-85%). I then recorded a 2 hour activity and saw a 3% drop (as expected). I have since left the watch face up and it has yet to drop a percentage (only about 2 hours so far).

For my watch, position clearly makes a difference. Something about having it face down causes a severe battery drain. Whether it’s related to the ambient light sensor or perhaps the gyroscope/accelerometer, I really don’t know. It makes no sense, but it is clearly happening.

@duffman19 interesting since that is supposed to be it’s “sleep mode” if I recall.

Last night, I performed a soft reset and left the Vertical on the table as usual. However, I didn’t notice that the top right button was accidentally pressed, which kept it in the activities menu and resulted in a 15% battery drain overnight.

I have Vertical Solar for the first week. What is your average battery consumption per week? Is 40% per week normal? I use 24/7, average an hour/hour and a half of activity each day, notifications off. I can’t use solar much anymore, no sun when it’s fall/winter

@martintrail With this use, normal day use is around 2-4% max/ day with no exercice. 1 to 1h30 activity / day should add around 2% of consumption/day.
If it’s you’re first battery cycle, you need a full cycle first, battery should calibrate properly.

hr always ON

*daily use everything OFF hr / steps / no connections with mobile / etch… only watchtime use.

Godzilla battery!!

@gerasimos hard reset yesterday…
full setup
full charge to 100% at 08.15

test training (walking) to see if things work at 08.30 for 7 min
battery at 12.15 : 93%

so 7% In 4 hours

@thanasis A friend of mine has a S9PP with a new battery and it lasts only a few days. In the evening the watch has 20% and in the morning 2%-3%. The watch is unusable at the moment.

martintrail

my battery consumption is higher than others here report. I get 8-10% a day with use as I write. I’ll wait for it to discharge to 0 and then we’ll see. So far it’s not too bad, but nothing great either

Ultrawalker

My Vertical had monday evening 79% battery when i left my watch in the closet.
2 days later without using watch i only have 57% left…
All those updates later Suunto can’t solve the problem of huge battery drain…
When will this be solved? Or never…???

larrybbaker

I tried resting my watch on its side as opposed to face down when not using it. I am still seeing the unusual drop. What is interesting to me is that it seems like up to 65% of battery is a slower loss but once it gets below that it seems to drain faster?

gerasimos

@thanasis never dohard reset.
I just drained battery once time 0% and the others about 15%-20% and full charge again.
After last update i charge as usual and i have the results above.
Small faster drain Problems i had only in the first software for two or three cycles of charge again now im ok

martintrail

@Ultrawalker I also noticed that it doesn’t discharge as quickly during activity as it does during normal wear. That’s really weird.

thanasis

@gerasimos it drained 14% today . That’s a lot !!

@thanasis never dohard reset.
I just drained battery once time 0% and the others about 15%-20% and full charge again.

Is it useful to drain battery till 0%? I am not sure if it is a good action or not for battery life…I am just curious as I read a lot of different opinions about this.

gerasimos

@thanasis i think this drainage it’s a lot… Maybe you can go at local Suunto service and measure the power and capacity of battery if it’s ok .
