How To Fix Apple Watch Not Tracking Sleep Stages/Sleep

There are several reasons why your Apple Watch might not be tracking sleep. You might have accidentally disabled Sleep tracking, wrist detection, etc., or there might be some software bugs preventing the Apple Watch from tracking your Sleep. 

Many people are encountering sleep-tracking-related issues with their Apple Watch. Therefore, we’ve researched thoroughly on this topic and put together this guide to help you resolve this issue. Read along to learn how to fix Apple Watch not tracking Sleep. 

1. Ensure Sleep Tracking Is Enabled

Your Apple Watch will only track sleep if you enable Sleep Tracking. It is a very basic step and most of you might have enabled this feature. However, we accidentally disable features and then wonder why they aren’t working. Therefore, we suggest you check and enable the Sleep Tracking feature on your Apple Watch and iPhone. 

2. Ensure Wrist Detection Is Enabled

The Apple Watch tracks your sleep by using motion and heart rate sensors. For this, the Apple Watch needs to be on your wrist. And, you must also enable the Wrist Detection feature. Disabling Wrist Detection disables heart rate tracking which in turn disables sleep tracking. Here’s how to enable the Wrist Detection feature on the Apple Watch. 

1. Open the Settings app on your Apple Watch. 
2. Navigate to the Passcode option. 
3. Turn on the Wrist Detection toggle. 

3. Set Apple Watch as the Primary Data Source in the Health App

There’s a Data Source option in the Sleep section of the Health app. Apple Watch needs to be at the top of the list among the various data sources. This will ensure that it is set as the primary data source. Failing to do so might be the reason the Apple Watch is not tracking your Sleep. Read along to learn how to set the Apple Watch as the primary data source.

If your Apple Watch is below 30 percent battery, it won’t track your sleep. This is done to preserve battery life. So, a low battery percentage might be the reason why the Apple Watch isn’t tracking your sleep. It doesn’t take a genius to figure out that the easiest fix is to charge your Apple Watch. 

We suggest you charge your Apple Watch above 80 percent before going to bed. And then check the next day if the issue persists. If it does, we still have several other troubleshooting methods below to help resolve this issue.
