Please fix the airplane mode

Battery died from 30% to 0 in about 5 minutes. Charged it back up and while charging with airplane mode and battery saver I'm getting notifications on the watch! Why can't they fix this it's been nearly a year of this crap. The battery drops from 100 to 70 in 1 day after only 2 x 8 mile runs no music, no LTE, no widgets no nothing. Live event sharing never works in an actual race.
