Race S: Extremely high battery use rate
-
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.

@2b2bff Do you have sleep tracking and 24/7 heart rate monitoring enabled?
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.

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…
