It really does not work like that…if 10%=3 hours it doesn’t mean that 100%=30 hours (small example). As the battery percentage is lower, it’s voltage gets lower aswell. The watch still demands the same power from the battery so the battery struggles to provide it, therefore getting discharged faster. You will notice your phone or your watch going drained faster from 30% to 10% than from 100% to 70%
