Source1Maker product pageus.suunto.com/products/suunto-race-2-all-blackRead 8 October 2026Current exact US table: 18 days smartwatch with daily heart rate and wrist-raise display, no training included. Standby/time-only 30 days with daily heart rate off and wrist-raise display. All-systems dual-band 55 hours, or 50 hours with AOD. All-systems single-band 65 hours, or 60 hours with AOD. The maker gallery battery-mode screen explicitly names Performance 55, Endurance 65 and Ultra 90 hours. Tour 200 hours is lower GPS accuracy with heart rate off. Ultra uses a separate power-saving preset. Exact Ultra GNSS bands, recording interval and AOD conditions are not stated. Days are converted exactly to hours. These are non-solar-augmented maker estimates. The launch release gives older 16/22-day daily-use estimates, which are not substituted for this current table.5Press releaseprnewswire.com/news-releases/suunto-introduces-race-2-and-wing-2-302539904.htmlRead 8 October 2026Launch wording says 16 days with continuous heart rate and 22 days with heart rate off. Current selected US product table now says 18/30 days with explicit no-training/wrist-raise conditions. Current claims are retained, with no explanation for the change inferred.
