    I have the original Apple Watch and sleep with it on in airplane mode. I only lose 5-10% of my battery at night. I have a friend who just bought the Apple Watch 2. She slept with it on (in airplane mode) and it went from 100% to 60% overnight. Has anyone tried sleeping with the new watch, and if so, had a similar or better result?

    I have the AW2 and have been using the Sleep Watch app. Last night I charged it right before going to bed so it was at 100%. This morning it was at 94%. I don't put it in airplane mode.

    @SamNatale How have you found the Sleep Watch app? I've been considering getting it, as I haven't found any other apps that try to auto-track your sleep (without having to manually start/stop) the way the FitBit does. Have you found it to be accurate? Reviews on the App Store seem to be mixed.

    This is an interesting thread. When I get my series 2 am going to give things a good test. Airplane mode is a solid idea, just not sure if really necessary!

    I used Sleep++ for a few months and I didn't need to use Airplane mode. But I don't toss and turn. I usually wake up in what seems exactly the same position I was in when achieving Lights Out. I doubt my display came on much if at all. I woke up with very little battery used overnight.

    The few times I've slept with mine on was on an overnight flight. I put it in airplane mode and the battery drain (as best as I can recall) was definitely less than 10%.

    I will wait to see how the battery life is on my AW2 when it arrives. If it is really good, I will sleep with it and ditch my fitbit surge, which is what I'm sleeping with right now. I don't sleep with it in airplane mode bc I get paged at night and need to be notified.

    Speaking of being notified, I set an alarm for 3:00 (1500) but didn't realize that I set it 0300. The Taptic response on my wrist in the wee hours was—startling—to put in mildly.

    Lol. I use the 24 hour clock, so that doesn't happen to me much.

    Works fine. I've gone to bed fully charged and I'm at around 96% in the morning. It's rudimentary, sleep hours and heart rate average. My Fitbit Surge also told me if/when I was restless. I suggested that to the developer, they seem open to adding it.

    That seems about right. Losing 6% charge over an 8 hour time period..Personally i don't think airplane mode actually does anything. I've tried one on in the Apple store and its really nice though

    I need to amend my earlier response. Sleep Watch updated their app to include more information. They now display your sleep quality on your iPhone, from Awake to Deep Sleep. So you get a visual on your restlessness. Seems to be pretty accurate too. I believe it now gives me as much information as my Fitbit Surge did.

    No appreciable drain on the battery as far as I can tell. And I never put the watch in Airplane mode at night.

    I went to bed with mine last night, using Sleep++ to measure my sleep. It was at 92% at 11pm when I enabled Airplane mode, woke up at 7am with 73% battery. Would you guys consider this normal? I thought it would loose less battery over a night.

    AW2, went to bed last night at 99% woke up at 97%. About 7 hrs sleep. Sleep Watch, no airplane mode.

    That's about the average battery use that I've been seeing.

    Is "Wake Screen on Wrist Raise ON" during sleep?

    That is amazing, only losing 2% per 7hrs. Maybe its because of the App, I've been wanting to get Sleep Watch. Would you recommend it based on your experience? Reviews are not that great.

    Please share what your settings are.. I would like to try your settings to see if I can get a similar result. (Brightness settings?, Reduce Motion On/Off?, Haptic Settings?, Background App Refresh On/Off?, etc). Thanks

    I'm guessing the variance in nighttime battery life (or depletion for that matter) depends mostly on how much someone toss and turns or lays still.

    ...Because most people leave Wake Screen on Wrist Raise ON when they retire for the evening.

    Have you done a test without engaging AirPlane mode, for a comparison? Are any of your Watch's apps allowed to refresh while in background? Is it possible your Watch brushes against your skin while sleeping? Do you sleep with your hands against your face, like people in TV commercials?

    I just did a test without turning Airplane Mode ON. So, I went to sleep yesterday around 12:00am, woke up at 7:00am. Using Pillow app this time on the Watch to measure my movements/sleep cycles. App refresh is always ON on my Watch, and I leaved Wake Screen on Wrist Rise ON on purpose. I went to sleep at 100% on the AWS2, woke up at 83%. So, in my case, Airplane mode ON or OFF makes practically no difference at all.

    I am still not sure about buying Sleep Watch ($4.99) to test it with that app. Waiting for SamNatale to share what his settings are for comparision. I think I am still consuming way more power than I should over a night. I will try same thing tonight but with Wake Screen on Wrist Raise OFF to see how much that helps.

    I suspected this would be the case. It might be significantly different if you were on a graveyard shift and slept during the day. I say this as I get virtually no email, texts, notifications, or alerts during the night. I do get a couple of email alerts in the early hours–0500-0600 or so. Obviously this can vary greatly among different users.

    I further suspect that Wake Screen on Wrist Raise will make a noticeable difference where AirPlane mode did not. Using the Do Not Disturb function on the Watch stops calls and alerts. For most of us, I don't think using it will help much if at all, similarly to using AirPlane mode. But a DND function that applied to WSWR might make a big difference. If you needed to see the display, you'd tap. I'd like a timed toggle in Settings and a manual toggle in the Control Center.

    I use the Sleep++ app and switch to a watch face with no complications on it so that it's not constantly refreshing. I also have background refresh turned off. My battery goes down about 7-8% and I have a first gen Apple Watch.

    Great idea! Switching watch faces can be even easier than my DND suggestion. I have a 'Movie' watch face (same as Rene suggested in another thread)— the Modular face with all complications OFF, and the time in red.

    Ok, another suggestion– a customizable Night Mode, where you program the hours of operation, notifications, WSWR, and brightness. And as with the iPhone, manual control as well.
