380mAh1Maker product pagesuunto.com/en-us/Products/sports-watches/suunto-run-2Read 14 October 2026The What's New table lists 380 mAh against 295 mAh for Suunto Run, and the page says 29% more battery capacity. The safety guide gives a 3.87 V battery, so 380 mAh is about 1.47 Wh.

Claimed battery lifeiMaker endurance claims with distinct operating modes and case sizes. With solar describes augmentation of that estimate, not hardware capability. Use false for ordinary claims without solar augmentation, true for explicitly solar-aided claims, and omit it when solar qualification is unclear. Source notes state AOD, GNSS, music and solar conditions. Do not create a normal-use row from an AOD-only claim. Low power denotes the maker battery-saver mode. Keep its typical, light-use and always-on claims separate from standard-mode claims. GPS power saving identifies an intermediate reduced-accuracy GNSS saving preset. Source notes retain the maker's preset name and published conditions. Max battery GPS is the distinct maximum-saving claim. When the maker has only one GPS saving preset, it is GPS power saving.

Days are converted to hours exactly. The headline says 10 days of daily training use, a separate claim whose conditions are not stated, so it is not stored. Tom's Guide lists 24 h as multi-band always-on, which conflicts with the maker's 18 h always-on figure, so the maker table is followed.
