Race S: Extremely high battery use rate

@sky-runner this thread is in the Race S forum and has Race S in the title. I guess it is related to the Race S then?
I know this is a thread in Race S forum because it was me who started it.
I suspect this is a software issue so it is likely the same across all models. Anyway, I haven’t had a chance to verify this with Race S. Perhaps I’ll do that next week. Currently I am using Vertical 2 and Race S is unused. -

Indeed as software issue, but maybe connected with the changed HR sensor algorithm? In that case it is a solution solely for the Race S. But who knows…
Interested about your results… -

@Tieutieu Not for me. I’m still seeing 20% drain per day.
With new firmware and not in airplane mode i get like 12% per 12h without any activity. No phone notifications . Seems a bit high no?
I get the watch very recently and in the past firmware i used a lot airplane mode -
Same problem here, charged last night 97% 24 hors later with two hors of trail running and map navigation. 63% I am having this issue since march.

My suunto vertical also experiences this extreme drain. You won’t get much out of this forum other than people posting to say how great their watch is. This is a an issue suunto no doubt know about but are in denial about or don’t know how to fix.

@gone-troppo I think reporting both cases is not wrong and may be helpful to further diagnosis. Last fw fixed my 20% drain per day.

It might have fixed it for now just because the watch was restarted and the watch state was reset. It might reappear again. In the past I had this issue on and off. I suspect this issue is connected to external HR sensors but perhaps it is more complicated.

In my case, with the Vertical 1 Titanium Solar, I’m confident the issues started with version 2.43.12 released in June 2025. I had been monitoring battery consumption, which increased from about 3% per day during normal use to around 7%. It’s not a dramatic spike, but it reduces battery life from roughly 21–22 days down to no more than 14–15 days.
Wouldn’t it be enough to check what changed between version 2.40.44 and 2.43.12? -
I recently disabled sleep tracking and it makes a huge difference on battery usage. Now with my usage (no aod, 7 - 10 hours gps usage a week) the battery last for over a week, were I used to charge it every 4 of 5 days.
I find sleeptracking not that useful so I don’t miss anything there.
What does puzzles me is that disabling sleep tracking also disables hrv. But that is also a minor loss. The day after a training hrv is lower and after a rest day it is higher. No surprises there.

@elbee
Still, before the latest upgrade battery lasted substantially longer with sleep tracking enabled
