Setting up

  • Download the Mi Fit App from Google Play.

The Mi Fit App can do the following for you:

• Track every workout
It records stats of running, cycling, walking, etc.
• Analyze your sleep
It tells you how you fared compared with other uses in terms of your amount of deep sleep, light sleep, and awake time. According to this, Mi Band 2 uses an extra sensor called the “Proximity Sensor” to detect the presence of skin, and a sensor called “Actimetric Sensor” which records and measures your movement while you are sleeping. This data is later converted into a graph by the help of the Mi Fit app.
• Measure your heart rate (on demand only) and alert you if it goes too high or your pace is too low
According to this, Optical Heart Rate sensors consist of Infrared emitter, and an optical sensor. Oxygenated and deoxygenated blood have different optical properties so as the infrared ray passes through your skin the blood absorbs some of it, and the rest is sent back. The optical sensor receives the reflected infrared ray, and a graph is made. This is used to determine your Heart Rate.
• Tell you how much battery your Xiaomi Mi Band 2 has left
• Help you set health goals like your target number of steps, etc.
• Set up alerts for your messaging app to be sent to your Mi Band 2
• Warn you that you have been idle for 60 minutes and you need to get your butt and blood flow moving well (perfect for those who have desk jobs)
• Help you customize the display in your Xiaomi Mi Band 2
• Unlock your screen automatically when your Band 2 is near
• Alert you of incoming calls (you have to take the call from your phone). You cannot receive a call from this smartwatch.
• Alert you of incoming SMS (you have to read the details from your phone). You cannot reply from this smartwatch.


The serious downside of the free Mi Fit App is it does not allow you to continuously track your heart rate. You have to press your band every time you need to record it. This is what you need the Mi Band Tools App for. It also:

• Alerts you of low heart rate
• Monitors your heart rate automatically in your customized interval
• Exports your heart rate readings to CSV
• Integrates with Sleep as Android

  • Charge your sensor before synchronizing

During storage, the battery might have run out. You need to have at least 10% juice to update your firmware and connect it to your smart phone.

  • Synchronize with your Mi Fit first and then the the Mi Band Tools app fill follow.

  • Snap your sensor to your band and enjoy!


Warning

Both the band and the charger contains Pb (lead) in excess of the threshold limit. Do not under any circumstance eat or bite the band. If you are weary of leaching, several bands are available on the market.


Preliminary Review

So far, the band is working well. Syncing it with the app was easy, too. The great thing about it is that it fits many wrist sizes well including mine (i.e. kid’s size). The band does not irritate me. For now, I take it off during I shower but keep it on while I wash dishes and nothing has faltered. The display is limited but I guess it’s fine as it is considering the price of around 3000 yen.

I need not connect it with my phone’s Bluetooth unless I need call/SMS/app notifications. It stores the reading and syncs data whenever my phone’s Bluetooth is on. Since I turned on my app notification (Line), I do keep my Bluetooth on but my phone’s battery still lasts the whole day so it’s fine. I noticed that the sensor’s battery drains faster, though. I started having around 50% battery and on the second day, the battery is down to 36%. I turned on my heart rate monitor at a 2 minute interval so maybe that is why.
