Apple WatchOS 7 sleep tracking: What it can and can’t do – CNET

Sleep tracking on WatchOS 7: so far, it’s consistent but not complex.


Scott Stein/CNET

Apple Watch never did native sleep tracking before — unless you downloaded third party apps — but it will soon. Apple WatchOS 7 adds a new sleep app and tracking features, including a wind-down mode, sleep schedules and even an alarm. The first public beta for the Apple Watch is here and I’ve been trying it out to see how it compares next to a Fitbit Versa 2 and Oura ring, all of which I’ve been wearing at the same time.

First of all, don’t update to the WatchOS 7 public beta if you can help it. Betas are experimental, it needs iOS 14 public beta to also be installed on your iPhone and Apple’s final version of WatchOS 7 should be here in the fall, maybe in a month or so based on previous years. I tried the beta on an Apple Watch Series 5.

But I was curious to sleep with the Apple Watch, because I’ve tracked my sleep before. On Fitbits, on the Oura ring, with bed devices, with Withings and more than I can count. 

This tracking has limits. Much like what Apple’s Kevin Lynch told me in June, WatchOS 7 sleep tracking is more about bedtime awareness and total time in bed. Along with that, there are wind-down and bedtime reminders.

Setting a sleep schedule feels familiar

Setting up sleep tracking feels very much like an extension the years-old iOS feature inside the Clock app that allows bedtime reminders and triggers a yellow shift in the light from your phone’s screen to enter a wind-down experience.

Sleep schedules get set up on the Apple Watch, or in Apple’s Health app. I picked 8 hours, spinning the clock around so my bedtime would be midnight, waking at 8am. I work from home now and the kids aren’t in school.

Consistent, but I go to bed way too late.

The Apple Watch dims and becomes bedtime-watch at night

I realized, as it was time for bed, that the watch screen was really dim, like the Watch Series 5’s ambient always-on display mode, but all the time. It looks like a basic watch face, shutting down complications and other details. Tapping and turning the crown brought me back to other features if I needed them…but I liked the idea here. Also, a dimmer, more low-key watch can mean saving battery life, which is smart anyway.

I get a gentle tapping alarm on my wrist

In the morning, the Apple Watch thumps with a wake-up alarm. I feels it like a steady tap. I think I missed the first few minutes it was going off. It offers a snooze option, which I do. It reminds me of silent alarms I’ve used on Fitbit and even Pebble way back. I love the idea as a way I won’t wake up the family if I have to get up early, but I wish the pings were a little more…pingy.

Morning to you too, Apple Watch (my battery life after wearing a full day and then sleeping without charging).

Morning gives me a little wake-up screen

I like the new greeting display, which shows battery life, time and weather. It’s a smart dashboard sort of look and it reminds me how much battery is left. After wearing it for a full day the day before, 26% was better than I expected.

I have to pick a new time to charge

Now that I’m not charging the watch overnight, when do I charge? It usually takes about an hour or so. I forgot my first day and the remaining battery life crept until 2:30pm before going dark. 

The day-plus battery on current Apple Watches just doesn’t feel like enough. I wouldn’t be surprised at all to see an extended-battery Apple Watch this fall, maybe even with enhanced sleep tracking sensors.

The Apple WatchOS 7 sleep app shows just overall sleep time, while devices like the Fitbit Versa 2 (right) show estimated light/deep and REM phases, plus a sleep score.

You could loop in more advanced Apple Watch sleep tracking apps

There are, to be clear, more complex third party sleep apps for Apple Watch. Apple points to these as ones you could use to enhance your analysis. However, I’d prefer Apple just did it and kept it all in the self-contained ecosystem. I’m not wild about adding extra apps with other authorizations when it comes to health tech.

It’s mostly a bedtime reminder and I wonder when more will happen

Just a few days in, the sleep feature seems about as straightforward as I expected. And, as bare bones. Being aware of sleep schedules is helpful and I love the system’s new powering-down and wake-up pings, which feel like necessary parts of making the Apple Watch a wear-to-bed device. But the battery life of the Apple Watch doesn’t feel ideal at all for sleep tracking and I’d like to see more analysis than just total hours and minutes in bed. Maybe something will come with the Apple Watch 6. Maybe Apple is going to announce a sleep study to pursue future features. But so far this feels like one shoe dropping in a larger Apple sleep tech solution.
