Battery capacityiPublished battery capacity for the stated case size. Rated and typical capacity are distinguished in source notes.

Samsung does not say whether this is rated or typical.2Maker product pagesamsungmobilepress.com/media-assets/galaxy-watch6Read 10 October 2026Same table: 44 mm 425 mAh, 40 mm 300 mAh.

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.
