What the differences mean

Days per charge uses each maker's own two ratings: days = 1 ÷ (23 ÷ everyday hours + 1 ÷ GPS hours), so every day has one hour of GPS and 23 hours of normal wear. These are ceilings built from rated maxima, not measurements.

GPS hours per 100 dollars at today's maker prices: Active Max 64 ÷ 1.6999 = 37.6 h (23.5 h on the 40 h estimate); Balance 2 33 ÷ 2.9999 = 11.0 h; Venu 4 45 mm 20 ÷ 5.4999 = 3.6 h; Series 12 10 ÷ 3.99 = 2.5 h.

GPS hours on the same footing

A battery headline like 12 days is a smartwatch-mode figure. What matters during a run is the GPS figure, and each maker states it differently:

Not recommended

Apple Watch SE 3 for distance training. Apple rates it at 7 h of outdoor-run tracking, the lowest in this table. That's enough for one long run, but not for a long run plus the rest of the day on the same charge. Apple's 18 h everyday figure already includes one 60-minute workout, so it needs charging every night. If you want an Apple Watch for running, the Series 12's 10 h and 24 h ratings give you more headroom.
