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. The three battery modes are Performance (default), Endurance and Power saving. They map to the 24 h, 30 h and 40 h rows as in the maker's all-modes line.

Smartwatch mode (claimed)iMaker normal-use smartwatch claim without solar. A watch with only an explicit AOD-mode claim has no value here. Workloads differ and source notes must be read.
