Charged it at 7:55pm. Went to sleep with the watch woke up around 80%. It's 2pm and it's at 22%. I haven't used the watch other than wear it to keep time. Its just doing the regular things like heart beat and tracking steps. Haven't used it for work out or any of the other stuff. Battery health is at 99%. Just got this last week. Is this normal use? Thought it was quoted 36 hours battery life under regular use.
My Series 4 is weirdly inconsistent when it comes to battery life. Normally, I wear it between about 7am to 9pm, and it usually has about 50% left at the end of the day. Right before I upgraded to WatchOS 10, I had a day when it was down to about 25% by 5pm. Yesterday, it was more or less normal (ended the day at about 45%), but this morning it went from 100% to 96% in a couple of minutes right after I took it off the charger. Since then, however, battery usage has been basically normal.
