    Just got my Apple Watch 3 from about 1 week, I use my apple Watch without sync. I sync the watch just 1 / 2 times a day then put in airplane mode.

    On my second charge first and second day it discharged about 20% / day.
    Yesterday before going to sleep was at about 50% and this morning was drained, if i push the side button i get the time + charge symbol.

    In settings I disabled background app updates, but i guess that app that drained my AW battery is autosleep.

    Any way to get battery usage by app?

    So ... You're using it purely as a watch and step tracker? You are really missing out a lot by putting it in airplane mode

    Yes watch, activity tracker ( I will test it with the bike ) and timer
    It really seems to me that for all the other things much more easy to get my iPhone

    What are you expecting with battery life? If multi-day usage between charging is what you want, then AW is not for you. Leaving the watch in airplane mode kind of defeats the purpose of a smart watch and you can buy cheaper options or fancy jewelry options. Be sure when you are sleeping you have it in theater mode so that the screen is not turning on repeatedly when you move around. I literally wear mine all the time and charge it for an hour before bed and while I am showering in the morning. That pretty much keeps it between 95%-100% when I head off to work.

    I don't really need to get notification on my watch, I prefer to have them on my iPhone.
    I use the AW as sport watch, I choose AW because I like the design bette than a Garmin or other sport watch.

    For activity tracking BT connection with iPhone is not needed, and yes an AW3 ( no cellular ) on airplane mode can last as long as 5 days, keeping the watch on during the night.

    Looks like you are using your AW the way you want to. Best of luck. I personally love using all features of my AW and charging before bed and while showering works perfectly. To each their own.

    Nothing built into watchOS. You might be able to download an app, but otherwise nothing except runtimes will be given. Are you sure the screen didn't come on a lot while you slept? Because theater mode will disable this. That is the only thing that would drain the battery 50% over the 6-9 hours people sleep. Normal battery loss for me overnight with everything running is only 2-4%.

    Thanks for that tip. I'm losing about 20% when I sleep. Will give that a try.

    I enallagi theater mode at night but I also had the AutoSleep App that it is supposed to monitor sleep
    That's why I was supposing that the app drained the battery.

    The night I got the drain I lost 50% of battery overnight otherwise I lose about 10% of battery.
    Do you meant total runtime or by app?

    That is the app that drained it then. AW does put apps in suspended mode if they are not actively running. But again, you really shouldn't worry about your battery. Keeping cycle counts down etc only do so much. The age of the battery does matter as well. My suggestion is just use the AW as you want to. If you find it is not running correctly, that is when you need to troubleshoot. If the app is running it probably is doing something in the background. And the AW app on iPhone one gives total run time, not by app.
