Battery drain
-
I was experiencing the battery drain (1% / hour). After a couple of recharges from 20% to 100%, and turning off and on it seems like battery is performing as normal now. I don’t know if battery will drain fast again after my today’s workout (will update).
-
I will turn off the notification from Cell on my watch to see the impact on the battery.and see if it is worth it. it looks like notifications are pretty battery foody…
I will finish discovering why my battery never last more than 10 days. I am tired in looking now.
-
Ok - I’m finally back to a normal rate (and actually have seen some definite improvements in drain during activity).
Started with 40% after update
Drained down to less than 10% and full charge
Still saw worsened battery life so allowed another drain to sub 10%Soft reset, full charge back to 100%
Now I’m at 94% after two days of all day/night wear and 3 hours of GPS activities.
-
My Vertical just went from 19% to 9% during night. That’s new. Soon 0% and then I will charge it to 100%
-
Still valid:

@Egika ok thanks, for the problem of abnormal battery consumption do you have to follow the guide so between 10% / 20% recharge or completely discharge the battery to re-calibrate it?
-
@MeazzaS9 as written in the FAQ section. A discharge to 10-20% battery followed by a full charge will be sufficient.
-
@Egika ok thanks, some say to bring it to 0 and then reload. I wanted to be sure
-
@Dimitrios-Kanellopoulos everything is perfect now!
- Soft reset
- Full circle 0-100%
Stable and powerful again.
Even the indication of battery at full charge saw me 100% and not 99% as previews updates

That’s not becouse of update. I got Vertical since November 2023, and sometimes it was charge always to 100%, battery jumps 98 ->99 and 99-> 100 at same “length- time”, but sometimes stop at 99%, and this 1% was added like after additional 30 minutes or something.
-
@Marton-Attila just same…
-
Do a full recharge from 0%- 100% did fix the problem for me altso.
-
I did a full discharge cycle yesterday (0-100%), left the watch on a table overnight (upside down, no OHR), and it is now at 90%. Something is surely amiss.
Battery drain during activity seems to be ok, but there are clearly some issues with daily wear.

I have a weird issue with my batteri on the recent firmware. I discharged it fully to 0% and waited for the watch to turn off. Then I charged it to 100% and left it on the charger at 100% for a few hours to make sure it was fully charged. I did this because from battery level 40% and below the battery level dropped drastically, up to 15% during one day even without activities.
Then I used it for a day like normal and saw that the battery drained to 97% after one day, which is all normal. Then I was out in the sun for 20 minutes and now the battery is back at 100%… I’m fairly sure the solar charging didn’t charge 97>100% after 20 minutes of sun exposure… So it seems like the battery calibration is just pure hit and miss?! Never experienced this type of inaccurate battery level on any device since NiMH and NiCd batteries went away…

@borgein I see this behavior with solar charging with a hight battery load above 95% too… but not only after the latest update, but just before for some month. You can load from 97% to 100% in some minutes
At the battery level above 95% there was a crazy behavior with solar charging from the beginning, but always a bit different. Sometimes I didn‘t see the solar symbol loading in plain sun above 95%… and they wrote here this was to protect the battery from overcharging… 
but nevertheless, I like my watch! -

I saw this. Not sure what you’re trying to tell me. I am on 2.35.34 and have now fully drained the battery twice (which would have been near impossible on previous firmware in such a short time) and am still seeing odd behavior. Is @Dimitrios-Kanellopoulos suggesting there is a fix in the works?

@duffman19
I understood from @Dimitrios-Kanellopoulos 's post, that current FW already contains a battery drainage fix, and that full discharge/charge is the only trick to do.
Now, I may be wrong, if in your case it is not working. I have no battery issues, so just sharing hints for any of those who are asking for the same. -
Another big loss overnight, this time 83-67% over 8 hours. This is again off wrist, face down on a table, this time with Battery Saver turned ON (so that didn’t work).
I recorded a 2.5 hour run yesterday and lost 4% in Performance mode, so that puts it at a potential 62.5 hours of total run time from 100%, right in line with Suunto’s estimate.
I have not been wearing the watch 24/7 the past few days as I’m currently testing others. However, I’m seeing about a 2% drop per hour while the watch sits off wrist. That puts the total run time at 50 hours from 100% while NOT recording an activity. So something is askew.
I thought perhaps the overnight drain was due to the fact that I still had sleep detection enabled, so it was actively searching for my asleep/wake times, but I’m seeing the same dramatic drop during the day.
