Battery consumption high
-
Hello, I would like to ask for advice. I have the watch now for 3 weeks and noticed the battery is discharging quite fast. I have been writing down the time and percentage yesterday and today as an example:
18.09.2025
07:00 - 60%
12:04 - 56%
19:32 - 48% (44min activity)
21:58 - 46%19.09.2025
07:33 - 40%
13:01 - 36%
14:03 - 35%It’s about 20% a day, I don’t play with it during the day. Watch was discharged and charged multiple times already. Is this normal? Thanks.

@OutdoorMan I am seeing a similar discharge rate on Race 1. My watch discharged from 14% in at 5pm yesterday to 4% this morning - that is 10% in 15 hours. The watch was laying on a table the entire time…
This requires an urgent fix!
-
@sky-runner noticed the same on my SR (15-20%/day). Soft reset fix the problem (bringing back to 6-8%/day), but after a while it reappears. Haven’t figured out yet what triggers it.
Wearing SR with SA on Android 13.
Previously owned/tested: SV, S9, S3. -
@SergioB @sky-runner it’s 21:13 and I am on 32% with just 44 min activities since yesterday 7:00 / 60%, so it’s almost -50%. I think it’s a lot. I am thinking about returning the watch (still within the 30 days return window), as I am not in the mood to be a tester for my own money.
-
@SergioB Yes, the high discharge stopped after I turn down the power and restarted the watch. I suspect this is related to external HR sensors. That is what Suunto has significantly changed in the last update. In my case I connected the watch to 2 different external sensors.
-
6% during the night (8 hours). Only 24/7 OHR is running, nothing else. Restarted it several times, no change.

I reproduced high power consumption on my second Suunto watch - Race S.
Today I finally upgraded it to the latest software. After that I connected it to Coros HR armband sensor and went for a run. At the end of the run it was at 17%. 7 hours later the battery went down to 12%. That isn’t normal. It didn’t have this issue before the update.On the other hand, my other watch (Race 1) stopped discharging after I I restarted it. Before the restart it was consuming roughly 0.5-0.75% per hour. After the restart the battery actually went up 1% and after that it went down 1% in about 8 hour of laying on a table, which is what I’d expect.

If you do a search you will see some of us are having major battery drain with suunto vertical too, for me over 40% a day sometimes. Something is seriously wrong I’m sending mine to suunto repair
-
@gone-troppo I doubt it is a hardware issue all of the sudden considering that my Suunto S started to have this issue right after the software update that I postponed by a few weeks and only did yesterday. So sending it to a repair won’t do anything. But perhaps it is more complicated than that.

This is mine, this is since first charge the day i received watch:
12.9. 19:15 Charged to 100%
13.9. 19:15 battery 91% (1h8m GPS)
15.9. 07:00 battery 81%
15.9. 13:00 battery 68% (2h5m GPS + AOD + Navigation)
15.9. 22:13 battery 65%
16.9. 20:36 battery 58%
17.9. (1h20m GPS) - didn’t write down percentages this day
18.9. 16:21 battery 43% (1h17m GPS)
20.9. 07:44 battery 31%
20.9. 20:19 battery 13% (3h30m GPS + 1h pause + Navigation)
21.9. 19:20 battery 8%
And it is new watch so i play with it little bit more than usual but not too much.24/7 HR + Blood oxygen + Sleep tracking + Raise to wake + BT notifications. Medium/Low brigthnes. And i wear it all the time.

Based on data on website
we should expect discharge around 1.8% each hour during GPS activity. And around 0.26% per hour during smartwatch with tracking enabled. And it says “up to” so i expect this numbers to be in best case scenario. And page not specify if sleeptracking and bloodoxygen tracking is taken to 16day battery life.

Pareil sur ma Suunto race S. Je dois la charger tout les 2-3 jours. Avant c’était tout les 5 jours

@Sixeela29 can you speak English please?

@Tomas5
Same on my Suunto Race S. I have to charge it every 2-3 days. Before it was every 5 days.

Hello, same for me with a Race 1 which I have since Nov 2023. Since the last FW update I have a daily discharge around 15 to 20% and before the update I was around 10 to 12%. With exactly thé same configuration and same usage. I have made a lot of trials and battery discharge manual records ; I have made a lot of trials to recover an acceptable discharge (start, stop, soft reset, no OHR, no Phone notifications,…) but no improvment seen. I have not tried to reinstall the previous firmware because I am a little bit tired with New FW coming with bugs with every time need to go back with previous firmware. I have made it too much time with the SR since I have it. It was not the case with my old A3 peak ; each new FW were coming with new features or improvments but no regression.

@Chris_Dx seems that a restart of the watch solves the problem for a while, until I connect the HR strap again. Then the battery drain starts again and also the weird ghost vibration, which is described in another thread. That’s at least what I have noticed.
-
@Chris_Dx Try turning off Discovery in System Connectivity menu. That might have made the difference in my case because the high discharge stopped and didn’t reoccur in the last two days.
It possible that Discovery mode makes other Bluetooth devices respond even outside of activity.
It looks like the last update has turned Discovery on.
The last update has had so many issues!
