      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. 🤡

          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

          As I mentioned earlier, even when I use the watch in power-saving mode, it hardly lasts 5-7 days. They really messed up everything.

            @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.

                      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.
