    Wouldnt that just translate back to it drawing 510ma of current? If you use 510mah in an hour that means you are drawing 510ma of current. That also means for all day battery life you would need a 8000mah battery at least which would make quite the chunky watch lol.

      No, the safeword is "0.002 cents"

        mAh ≠ mA/h

        So it would be

        mAh / h => mA

        Then?

          Yeah, this seems like a metric specifically chosen s.t. it makes intuitive sense to the average person AND it has a nice physical interpretation. Similar to how EU efficiency labels show power draw in W as kWh per 1000h of use

            Really? I have a camera that is rated "3.7 V, 2 A" but only draws that amount from the battery when the flash capacitor is recharging. Yes, the normal current draw would be more helpful, and in case of a watch, the standby current.

            This may be the charging current but it would be pretty unusual to pick a value slightly above what legacy USB can deliver (500 mA).

            The max rating is important so your powersupply/battery can be sized accordingly. No powersupply can provide a abitrary current at their rated voltage.

              The battery has the storage capacity to pass 510 mA in an hour. If you discharge at half the capacity of 255 mAh (0.5C) it will be empty after 2 hours.

              If it was to draw 51 mAh (0.1C) it would last 10 hours.

              But if it would draw 1020 mAh (2C) it would only last 30 minutes

              This is the winning response I think.

                That sounds nice for appliances that run intermittently like refrigerators

                  It's got a constant rate of frequency acceleration?

                    I'm particularly fond of kWh per year tbh: E/t•t/t

                      Yup, this is just saying 510mA in a weird way
