Sleep Mode data not recorded

After ios 18 update sleep data was not working bro the data was not available after the sleep mode ends I lost my 4 days data

hi bro, is your apple watch also updated to latest WatchOS version?

No bro only mobile iphone13

Oh, sleep tracking works better with apple watch bro. otherwise it will be less accurate in detecting the sleep pattern. are you keeping the iPhone closer while sleeping? may be in iOS 18 there could be bugs affecting, so give some time. we are expecting iOS 18.1 with more bug fixes. that will help fixing it.

I’m experiencing the same issue. I’ve updated to version 18.1, but it still isn’t recording any data. I don’t have an Apple Watch, but previously the data was being generated properly. Now, however, it’s not generating any data at all. Is this a bug, or are they trying to encourage us to purchase an Apple Watch?

hi bro, are you using iOS 18.1 beta versions or updated yesterday night and checking the sleep tracking feature? you are keeping the iPhone nearby correct while sleeping?

Hi bro , I’m not using the beta version. I updated the standard version the day before and checked the tracking yesterday, but it didn’t work either. I used to keep my mobile nearby as well.

tried it yesterday and it is recording false data bro. showed as 1 hour 30 mins sleep recorded. I think something is wrong with the latest update possible. submitting a feedback using feedback asisstant app in beta version to let apple know about it too. hoping a fix arrives in upcoming update.
