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.

Heavy use changes HR to once per minute, adds stress and eight hours of sleep-breathing monitoring, 60 minutes weekly calls and longer screen use. Saver disables health functions and GPS. Continuous GPS claim has no explicit multi-band or music condition. Day claims convert exactly to hours. No AOD runtime is inferred.

Days converted exactly to hours. Normal usage has no always-on display and 180 minutes of GNSS exercise per week. Heavy usage turns on the always-on display with the same monitoring and so is stored as heavy use, not as an always-on-only claim. Full test conditions are on the page.
