Race S: Extremely high battery use rate
-
@elbee, my friend, we keep complaining here and take out our frustration; that’s it. I am sure Suunto software developers aren’t bothered to read anything; even if they are, they are busy adding functionality as the marketing team forces them.
The issues of poor battery and forced customisation by the Suunto software design team, whatever they think is good, have been escalated in different topics so many times, but the end result is that they do what they want to do; once you buy it, it’s your problem.
Once I was chatting with the support team about the battery just a few weeks after getting a new watch, and they wanted me to upgrade to a new one rather than give me any concrete reply.
After Suunto moved from Finland, they have been going down day by day.

I have a Race S, and 2 weeks ago i did a factory reset because of something, i don’t recall what.
But now the battery also goes down much faster than it used to, equivalent to what other people here are reporting: 7-10% per night.
Bluetooth announce is off
i now even put oxygen stuff disabled (for night monitoring)
and DND for the night -
Right now, the Suunto Race S has fewer features than a Wear OS smartwatch, yet its battery life is even worse. It’s truly disappointing.

I did that a few times already without any improvements. And the end result is that you spend more time reconfiguring the watch.

@withManish I get to about 4 days easily. With AOD and notifications enabled. And about an hour of GPS tracking per day…
-
@2b2bff Do you have sleep tracking and 24/7 heart rate monitoring enabled?
-
Bought my Race S in December 2024. With no activities recorded but with sleep tracking turned on the battery went from 98% to 73% in 25 hours. This does not seem excessive.
-
@jobtoll The manufacturer claims that if you train with GPS for 5 hours a week and keep heart rate and sleep tracking enabled, the battery will last at least 5 days. However, I’m only getting 3 days, which is really disappointing.

Indeed, I have

Where have you read this?

How much battery life do you get? This is what is claimed on the website.
I have a setup such as “Daily heart rate off, display wakes on wrist-raise”, yet I get 7 days, hardly forget even 10 days.

@snow 5, just as a watch, it hasn’t been working for 7 days; generally, 5-6 days max. This all started after the firmware upgrade. Otherwise, it used to give 10+ days on a charge as a watch, and with 10+ hours of GPS-only (no heart rate), it used to give me 7 days of battery easily. (Don’t have Bluetooth on for any notifications)
I have noticed that 2 to 3 hours of GPS use drains 6-8% of the battery.
I have already lost hope with Suunto on this matter. -
I’ve noticed that significant battery drain is caused by the 24/7 heart rate monitoring mode. Previously, the watch would measure heart rate every 3 to 5 minutes; however, after the software update, it monitors continuously—24/7—without any breaks unless you take the watch off your wrist.

@2b2bff
Does this look a lot to you? -
@snow
No way. One night with hr enabled is about 10% batter.
One full day with 1 to 2 hrs activity with gps is some 25%-30% at least -
Does this look a lot to you?
It is not ample, but given the small size and AMOLED with AOD it is ok. My Epix Pro 47mm that has about the same screen size, but a bigger housing, gets me one additional day…
Fenix 6S Pro, with a smaller housing, but MIP has been another day extra with about the same usage after 3 years of using it…

But this is not the point. The point is that compared to first FW versioms now battery is crap. Before it was ok, now it not -
Besides the quite frequent 15% battery usage in 1 night (charge to 100% in the evening, wakeup with 85% in the morning), which can be mitigated by frequently rebooting my watch I now also had a annoying high battery usage during a hike.
I started the hike with 48% and a expected runtime of 13 hours. Aod is off. Gnss settings default and used navigation.
After almost 7 hours the watch went into battery emergency mode: no gps, no map, no heartratesensor. (The last one I couldn’t care less, but no navigation was quite annoying)
I ended the hike just over 7 hours with 1% left. A couple of minutes later it just shutdown.This is really far from the advertised and expected time.
(Unfortunate suunto doesn’t have ‘resume later’ so during stops I count pause the time but not the gps)

For me and my usage it is now 4 and has been 5 days… not a big issue - for ME…
“Crap” is different…Suunto Race S
