Is it normal to have a quick battery drain overnight? Like it drains 3% to 5%? I charged it last night to 100 and have 16 days left. When I woke up my battery has gone down to 95% at 15 days left. I have my pulse ox on manual and my watch is an instinct e 45mm.

Is the passcode entry animation on garmin instinct 3 and instinct e the same?
