Battery life detail
Battery life detail	Without solar: smartwatch up to 36 days; battery saver up to 92 days; GPS only 120 hours; all satellite systems 80 hours; all systems plus multi-band 60 hours; all systems plus music 22 hours; max battery GPS 210 hours; expedition GPS 77 days. With solar: smartwatch 90 days and battery saver unlimited assuming all-day wear including 3 hours daily at 50,000 lux; GPS only 320 hours and all systems 144 hours assuming continuous 50,000 lux; multi-band 90 hours under the maker's 50,000-lux/SatIQ conditions. Solar claims are conditional, not ordinary indoor runtime.	Headline figures are 51 mm without solar: up to 30 days smartwatch and 48 days battery-saver watch mode. 47 mm: smartwatch 21 days/28 with solar; saver 34/58 days; GPS-only 67/92 h; all satellites 48/59 h on current UK web table (September 2026 owner guide instead says 49 h with solar); multi-band 37/43 h; all satellites plus music 13 h; maximum-battery GPS 132/283 h; expedition 34/58 days. 51 mm: smartwatch 30/48 days; saver 48/107 days; GPS-only 95/149 h; all satellites 68/92 h; multi-band 52/65 h; music 18 h; maximum-battery GPS 186/653 h; expedition 50/118 days.
