So, let’s get it to it shall we?
In a nutshell, this is how the Xiaomi Band Detect Sleep
The Xiaomi Band tests sleep using the accelerometer and the heart rate monitor. It tests the movement during deep sleep and a slower heart rate indicates REM sleep. This data is not as accurate and has a 78% accuracy rate. The Xiaomi band also does not measure how long it takes for the user to fall asleep.
How Xiaomi Band Detect Sleep
I mean honestly, if the Xiaomi smart band can actually track our sleep that would be pretty cool. So, I decided to act on this conundrum and decided to jump into the rabbit hole of wearable tech and sleep tracking. And I finally found out How Xiaomi Band Detect Sleep:
The Xiaomi Band has certain sensors like Accelerometer, Gyroscope and PPG (Heart Rate Sensor) to track body movements and heart rate to determine whether the user is in a light sleep stage or deep sleep stage. The latest Mi Band 6 also uses respiratory data to determine the REM sleep cycle of the user and provide comprehensive sleep pattern and health data. Most importantly, it can allow the user to improve their quality of sleep and contribute to optimizing their health.
So, why is it important to keep a track of your sleep?
- Tracking your sleep essentially leads to improving your sleep and thus your health. By tracking your sleep you can sleep at the right time and sleep for the right amount of time.
- Most of the people actually sleep for a far less amount of time than their body requires. Doing this on a consistent basis leads to adverse health effects. So, using a sleep tracker like the Xiaomi Mi Band helps keep a track of how much time your body actually deserves.
What Sleep Parameters does the Mi Band track?
For example, the Mi Band 5 estimates the amount of time the user spends in all three stages of sleep. This band tracks the users sleep while the data is recorded in the Mi fit app. This can help identify if the user is suffering from sleep issues. It specifically analyses how much time you spend in each stage of sleep.
- Basically, this band will provide the user with information regarding their sleep condition and most importantly it will also tell the user how to improve their sleep. The information and sleeping habits are represented in a pictorial graph.
The Xiaomi Band specifically reads the three stages of sleep and gathers various data from the duration the user spends in each sleep stage.
How the Mi Band tracks Light Sleep
The Mi Band 3, 4 and 5 tracks light sleep by using a combination of an accelerometer and the heart rate sensor. During light sleep, the body slows down and movements are extremely minimal. As you drift between being awake and asleep, your heart rate also tends to slow down. But only by a bit. The Mi Band captures this first phase of the sleep cycle by reading the minimal to zero movements and the slow drop in heart rate. Light sleep is known to help with both physical and mental recovery. Which is why power naps work wonders.
How the Mi Band tracks Deep Sleep
Once, you’ve been in the light sleep stage for a few hours, you gradually drift off into deep sleep. This heavy sleep shuts off both the body and mind, which is why it’s harder to wake up. During this sleep stage, the body will not move and will be extremely unresponsive to external stimuli. Most importantly, the heart rate drastically slows down. The Mi band captures both these parameters and understands that the body has transitioned into the deep sleep stage. Deep sleep helps with psychological recovery and muscle recovery. This is also the time when the body supports the immune system.
How the Mi Band tracks REM sleep
REM sleep or Rapid Eye Movement Sleep is the final stage of our sleep cycle. Most importantly, this is the stage of sleep where we dream. While the Mi Band 3 and 4 can’t track this stage, Xiaomi’s latest Mi Band 5 makes use of the Accelerometer, Gyroscope, PPG sensor and respiratory data such as blood oxygen to track the REM cycle.
Once, the user wakes up, they are notified by the Mi Fit app as to the status of their sleep cycle. To access this information all the user has to do is click on the notification or run the Mi fit App.
- A human being goes through multiple cycles of these stages and the number depends on the individual. Everyone’s optimal cycle is different. So, a comprehensive tracker like the Mi Band 5 does is extremely useful.
- You simply have to click on the tile that mentions the duration of sleep to get specific details regarding the length of your sleep, sleep quality analysis, a overall sleep score. The Xiaomi Tracker also compares your sleep pattern with other people for an objective result.
- Other than asking you how your feeling for even accurate recommendations, the Mi band also let’s you access your sleep statistics in terms of days, months, and years. This comprehensive information will allow you to improve your sleep in asytematic and gradual fashion.

Mi Band knows you are sleeping when you activate the sleep tracker and your movements are limited which is checked by the accelerometer. It also uses the heart rate monitor to figure out if the user is sleeping. A slower heart rate is considered to be sleeping.
What is the Xiaomi Band Sleep Tracking Accuracy?
The Xiaomi Band sleep tracking accuracy is not that great when compared to a traditional sleep tracker like a Polysomnography machine. But when compared to sleep trackers like Fitbit, the Xiaomi band is slightly better but not as good as the Fitbit. The sleep tracking accuracy rate is around 70% for the Mi Band.
How does Mi Fit Calculate Deep Sleep?
Deep sleep is tracked using the same accelerometer. The assumption that the Mi Fit app makes is, when there is lesser movement, then the user is in deeper sleep which is not true. The deep sleep calculation of the Mi Fit is not accurate and should not be considered medically relevant.
