iOS 10 Bedtime - sleep analysis not working

i had the same problem for a while.

try not to put your phone on silent during the night. then it works. i just left it on, plugged in my headphones and then it somehow activated the sleep analysis and saved everything to the history.

maybe it's not the case. but it worked for my iPhone

I had the same experience, but have discovered you can manually enter your sleep patterns using the Health app. Launch the Health app, choose Sleep, tap the Sleep Analysis chart (which -- if you're in the same position described -- will only have your first night sleep times populated). Tap the plus sign (upper right), and you can manually enter the start and stop times for when you're "In Bed," "Asleep," and "Awake." Tedious, I know, and it seems there's got to be another way -- in addition to pairing the App with other devices.

Have you tried unlocking your iPhone first and then checking the sleep data? I have swiped up from the bottom and pressed the bedtime button from the lock screen and it shows no data, but if I unlock the iPhone first then swipe up and press the bedtime button the data is populated.

I have the same issue - the sleep data is only partially recorded and intermittently records nothing (more often recording nothing than recording). All settings are set to allow permissions. The phone has been fully restored a number of times and this has happened for months ever since I got the phone - it's iPhone 7 always updated to latest iOS. Could this be a hardware fault with the handset itself?

Continued - I thought it might be because I was wearing no wristband but I just got Apple Watch and the data is still intermittent and missing. Far less accurate than the original sleep tracking wristbands from years ago.

I just figured it out! It only records data if you turn it off correctly and there is only one way (that I know of) to do this. When you hear the alarm, press "stop". If you try to simply turn it off between snoozes like I was doing (and probably most others by the look of this topic) it will not record for that night. Let me know if you figure out a way to stop between snoozes.

I've been talking to apple support about this and they suggested turning off the 'scheduled' option in the 'do not disturb' area of settings while at the same time having the bedtime alert set to 'at the time' rather than x number of minutes before. I tried it last night and it worked so fingers crossed this may be the fix - I also pressed stop rather than snooze as someone here suggested so I'm not sure which change worked

Settings > do not disturb > scheduled

Bedtime > options > bedtime reminder > at bedtime

I spoke too soon - the fixes suggested by suppprt didn't work on a second night running so it's still just randomly recording and none of the suggested or above fixes have worked for me. Back to the drawing board. I have a support case running over this and will post here if a fix is found for mine but so far nothing.

To turn it off between snoozes and still have it record sleep time: when the phone is in standby (on but with dark screen), press home button, see notification of sleep mode running, swipe left in notification, then tap "clear".

Apple support have been trying to sort mine out but so far nothing they suggested has worked. I have found that other downloaded sleep apps still work for me though (while using Apple Watch) and the results get recorded in the health app but the source appears as the downloaded app rather than the clock.

I was facing the same issue. The app recorded my sleep data for 2 days & then stopped, without me having changed any settings. I went in to my Settings > Privacy > Health (App) > Clock, turned off the (2) permissions for 'Allow Clock to WRITE data' & 'Allow Clock to READ data' and then turned these back on. The missing Sleep Data from the night before was now on my Bedtime & Health Apps. Hope this helps. :)

I Have also been wondering how bedtime works. How does it analyze sleep? With just motion? Does it have to be on my bed or can it be on my nightstand? How does this compare to an app like sleep cycle? I've been using that for many months now, and it still seems better than IOS bedtime. Does Bedtime wake me up according to my light sleep cycle, or only at the time I set?

bedtime is an inbuilt feature in an ios 10. you have to first set the wake up time and go to bed time. on basis of which it sets your sleep duration. it also alarm you at bedtime and at the wake up time. you can also reject the alarm at bedtime and it will not consider it in your sleep duration and graph will be according to that. it will now analyse the motion of your iphone. sleep cycle is not inbuilt but more reliable and accurate than bedtime.

I Don't think this answers the question on why is it only recoding history for the first night but stop recording history.

Glad I am not the only one who seems to be having the same issue. Worked for two nights. I have noticed no data has been collected since Sept. 16th on my sleep analysis. And just like you, I haven't touched anything in the settings. I was really enjoying this feature 😟
