Battery drain

duffman19

@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.

@martintrail
2.37.48 installed
1st November 100% charge battery
18 November 38% remaining

-training hours 29 (trail run mainly- openwater swim - mtb)

always PERFORMANCE battery mode-
sometimes with map navigation and backlight ON at 6 night sessions.
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

timecode

@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 .

thanasis

17% drop in 24 hours with just 7min of test training .
Obviously there is an issue
The only change made : I switched to this watch face :

gerasimos

@misu763 its not official suggestion and not necessary. With this way recalibrate the battery if you have issues after big software updates and only for once time… you dont need do this every time

gerasimos

@thanasis i don’t think watchface cause drain problems… only the background backlight , wifi / Bluetooth ON etch in watch time mode.
I have always off WiFi and Bluetooth and my watch connected automatically in my phone after first pair.
Everyday my setup:
Sleep tracking off
Blood oxygen off
Hrv tracking 24/7 off
Mobile notifications off
Brightness medium / standby off / raise to wake off / backlight OFF

Activities always performance everything ON

Also i have Ocean watchface still 33% from 1 November

thanasis

@gerasimos turning mobile notifications off is not
Something that I want to do and I don’t think that Suunto are calculating their estimations on such conservative an approach .
Thanks !!
