What You'll Learn
The Mi Band 2 can automatically detect when you fall asleep and wake up
The Xiaomi Mi Band 2 is a fitness tracker that can automatically detect when you fall asleep and wake up. It uses a built-in accelerometer to detect motion and a heart rate sensor to estimate when you fall asleep. The Mi Band 2 can track several sleep metrics, including sleep duration, sleep and wake times, and sleep quality analysis. It also identifies sleep during the daytime if you sleep for a longer period.
The Mi Band 2 has a vibrating alarm that will gently wake you up in the morning or after a nap. It also has an alert to let you know when you need to get up and move around, which you can set to notify you at specific times during the day. The device vibrates when you've passed your daily goal.
To track your sleep using the Mi Band 2, you can use the Mi Fit app. The app allows you to view the number of minutes you weren't sleeping, specific falling asleep and waking up times, and the amount of light and REM sleep you got. The app also displays today's activity, the most recent heart rate measurement, your night's sleep, and your most recent series of goals. You can view graphs by day, week, and month, and break down each graph's timeline into sleep, activity, and walk.
The Mi Band 2 is an affordable option, costing around $30. It has a built-in optical heart rate monitor that can track your resting heart rate and your heart rate during activities such as hiking, sprinting, or jogging. The automatic heart rate tracking feature can be used while you're sleeping, but it will drain the battery.

It can also identify deep and light sleep
The Xiaomi Mi Band 2 is a great option for those who want to track their sleep patterns without breaking the bank. The device automatically tracks sleep, including the duration of sleep and the number of minutes spent awake during the night. It also identifies deep and light sleep.
Sleep tracking is of three types: light sleep, deep sleep, and rapid eye movement (REM) sleep. Light sleep is a transitional stage between being awake and falling asleep. During this stage, you can be woken up easily, and body movements are minimal. The Mi Band 2 uses an accelerometer and heart rate sensor to track light sleep. When your body movements and heart rate slow down, the device detects that you are in the phase of light sleep.
Deep sleep is a state of complete unconsciousness, during which your heart rate and blood pressure drastically slow down. This stage of sleep is vital for building immunity and recovering from physical fatigue. It also improves declarative memory, such as semantic and episodic memory. The Mi Band 2 can identify deep sleep by tracking your body's reduced movements and heart rate.
In addition to tracking sleep stages, the Mi Band 2 also monitors your sleep breathing quality. This is done through blood oxygen sensors that measure your blood oxygen saturation percentage. By tracking your sleep patterns and quality, the Mi Band 2 can help you understand your sleeping habits and make improvements where necessary.

The device has a vibrating alarm
The Xiaomi Mi Band 2 is a $30 fitness tracker that can automatically track your sleep. It can detect when you fall asleep and wake up, and it can also distinguish between deep and light sleep. The device has a vibrating alarm, which is a great way to gently wake up without disturbing others. The vibration is strong enough to wake even heavy sleepers, although some light sleepers have reported that it doesn't always work for them.
To use the vibrating alarm, you will need to enable Bluetooth unlocking and set up a PIN, pattern, or password for your phone. This is because the Mi Band 2 requires synchronization with your phone's default clock app to function as an alarm. You can also use custom applications like Sleep as Android or Notify and Fitness to set up the vibrating alarm, which offer more features than the default Mi Fit app.
The Mi Band 2's vibrating alarm can be customized to suit your preferences. For example, you can set it to vibrate for a certain duration or intensity, or even set it to vibrate only for the first minute of the alarm. Additionally, you can combine the vibrating alarm with a traditional alarm or radio by setting it to go off a few minutes after the band vibrates.
While the vibrating alarm is a convenient feature, some users have reported issues with accidentally turning it off in their sleep or while rolling over. To prevent this, you can create custom actions or use a separate device, such as your phone, to disable the alarm.

It uses body movements to monitor sleep cycles
The Xiaomi Mi Band 2 is an affordable fitness tracker that can automatically track your sleep. It uses a combination of body movement detection and heart rate monitoring to determine when you fall asleep and wake up, as well as to identify the different stages of your sleep cycle.
The Mi Band 2 has a built-in accelerometer that detects body movements and a heart rate sensor to estimate when you fall asleep. During sleep, the device continues to track your heart rate and uses the data to provide insights into your sleep quality. It also identifies sleep during the daytime if you sleep for an extended period.
The Mi Band 2 can distinguish between light sleep and deep sleep based on body movements and heart rate changes. Light sleep is characterised by minimal body movements and a slower heart rate, while deep sleep is associated with a further decrease in body movements and a more significant drop in heart rate. The device can also detect when you wake up briefly during the night, even if you fall back asleep within a few minutes.
In addition to movement and heart rate, the Mi Band 2 considers other factors such as breathing patterns, temperature, noise, and light to analyse your overall sleep pattern and quality. This data is synchronised with apps like Google Fit and Zepp Life, which provide a more detailed analysis of your sleep, including sleep duration, sleep regularity, and breathing quality.
The sleep tracking feature of the Mi Band 2 is a valuable tool for understanding your sleep habits and patterns. By monitoring your body movements and other physiological indicators, the device can provide insights into the quantity and quality of your sleep, helping you make informed decisions to improve your sleep hygiene and overall health.
