      @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.

                  ~5.2%/h, multi-band, bt enabled for chest strap H10, rise to wake, using only map view with bottom field enabled

                    @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?

                          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

                            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…
