I'm using the highest setting, Ultra, and it's already at 55% capacity in three days. Two of those days I slept through it, using half again. The first day used 35%, and the remaining four days only used 45%. I need to use it sparingly, otherwise it might run out of power. I wrote something very interesting, and I should be able to release it next week. PS: Claude is the least efficient. With Max, using Fable 5.1 for moderate inference, and only as an auxiliary tool, it was down in three days.
