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.

I am loosing 3-4% during the night (6-8 hours).
I am still facing battery drainage.
I have read here, and my only guess now are watchface and the complications… There must be an issue here. why some of us have battery drainage and other not?
During an exercise and gps on, the battery have always behaved normally, and it is nice to see (only had an issue with suunto app+ when they are multiple, there was a bug of battery drainage as well)

I have turning everything off/low, wifi off, notifications off, rize to wake off, no backlight etc… only Bluetooth is always on with my phone and are pretty much all the time close to each other.

Now I have the original watchface vrtival with weather , day/night, and pressure trend.

I am loosing in average 10% a day. i think i have tested everything, calibration, soft and hard reset.

I am running out of ideas. I want to send my watch for repair, but it is a shame, i ma sure it is software the issue.

what to do guys?

Outdoorsy

@Antoine-Lancrenon Just a suggestion. If you think it’s a software issue, you could rollback to pervious version and see if that helps. There are some posts that show how to install previous version.

I have not installed the latest software on my SV after reading about the issues posted here. My battery usage has been very good.

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).

Nope… still the same. Draining fast af.

Antoine Lancrenon

@Outdoorsy I had pretty much the same behavior before the update… May be it is even worse may be little bit. But since I bought the watch, i have never had more than 10-14 days of battery.

whether i have activities or not, it is pretty much the same. but i am usually doing 2h GPS tracking/activity a day, and some day more. but as I said, the battery drainage is between activities (watch mode and night basically)

is the h24 HR tracking is the culprit? i want to use my watch full potential. and HR tracking is part of my daily routine…

thank you for thoughts

I had same issue (Suunto Race, 11 % per day after new update). My experience is that is connected with weather widget which I added to my watch face. Now I have only steps and date and battery consumption seems to be same like before the newest update. (I noticed on some other discussion that there is same issue with Sun rise widget). I think that widgets depended on internet have higher battery consumption.

Ars Vitae

@Antoine-Lancrenon Did you do exactely what many here advise? I mean, did you let the battery discharge below 20% and then charge it to 100% (while not forgetting to restart the watch after charging it to 100%) ? If yes, I can advise you also to make that watch reboot after battery discharge. Then you will see that your watch battery will gain some more percentages of “life”. For me it was from 16 % to 23 % after rebooting. Then let your battery to be discharge again below 20 %. Then charge your watch to 100%, reboot and it’s done. Sometimes, if it’s not enough, you need to repeat this operation. Some crazy stuff but I’ll try to explain later how I understand this battery drain after each firmware update.

@Tomas-Fejfar sunrise/sunset does not depend on internet connection though.

@Marton-Attila my Race S has the same issue. I noted it after a long hike. Before the hike it worked normally (8% drain with 1 hour activity, no gps per day), afterwards the hike the battery drains really fast (more than 20% with 1 hour activity, no gps per day)

Tomas Fejfar

@isazi OK but I can definitely confirm that I am back on my 5.5 - 7 % daily battery consumption without weather complication.

Patrick Rx

@Tomas-Fejfar I enabled Suuntoplus apps Weather and Weather forecast for the hike. I disabled it this morning in the hiking profile without starting any activity (just disabled the presets for the next activity start).
Since then it seems to be draining the battery normally again.

Tomas Fejfar

@Patrick-Rx I was referring to the weather complication on the watch face. My apologies for any confusion.

duffman19

My SV went from 33-15% last night, same huge drain as the last few nights. I removed all complications from the watch face and have done two complete drain/recharge cycles.

duffman19

@Ars-Vitae Can you explain my battery loss? I’m losing 2-3% / hour when I’m not wearing the watch. I’ve performed two full discharge/recharge cycles and multiple resets.

Yeah I also see this on my SV Ti Solar. I have done recharge cycles, but from around 40% the battery capacity drops at an alarming rate. Also when I fully charge my watch, after a full charge cycle, and a day of wear, it goes down to 97% then up to 100% again without ever touching the charger… This is from the solar ring after just being outside for 20 minutes in the sun. It seems to me like the watch uncalibrates the battery by itself in some way. Buggy and unreliable.
