Innovation is the need of the hour, and therefore Xiaomi brought some cool new amazing features to the new Xiaomi Mi Band 3.

Weather forecasting

  • With the increase in the screen real estate, Xiaomi made sure that they can display a little bit more information. And with that, they came up with the most useful feature, the weather forecasting.
  • Weather forecasting works right through your smartphone itself. Xiaomi Mi Band 3 directly updates the weather data from your phone, but the phone needs to be connected to the internet. This will enable the Xiaomi Mi Band 3 to fetch data more efficiently.

What all you can see?

  • Temperature,
  • Quality of air in percentage,
  • Maximum and minimum temperature,
  • Forecast of the weather for three today
  • Tomorrow and day after tomorrow- temperature prediction
  • Xiaomi claims that this features will even reduce the use of their smartphone as the data will be readily available on their Xiaomi Mi Band 3.


  • So, the predecessors, Xiaomi Mi Band and Xiaomi Mi Band 2 had the haptic feedback for notifying for the messages and notification.
  • Xiaomi Mi Band 3 combined that haptic feedback and took advantage of the large screen size displaying a lot of notification information.

Find the phone feature: Xiaomi Mi Band 3 review

  • Well, in the previous versions of the Xiaomi Mi Band we have seen that the smartphone can activate the band’s motor. This enabled us to locate the band. Which is good but isn’t practical.
  • But in Xiaomi Mi Band 3, we can locate the phone also.
  • This feature enables the users to find their phones with the help of their Xiaomi Mi Band 3. You are required to push the find my device button.
  • And the Xiaomi Mi Band 3 will play some beep sounds via your smartphone (device connected to the band).

Note– there is only one downside, during our Xiaomi Mi Band 3 review, we found that your smartphone may not play those sounds if the device’s volume has been set to the lowest or are disabled. These results applied to our testing device, the iPhone for Xiaomi Mi Band 3 review.

Secondary display

  • There is an additional display provided within the main display which only shows important information like, the heart rate, step counts, and calories.
  • This feature, they are calling it as ‘dashboard.’ Using the Mi-Fit app, you can choose what all information you need to put in the ‘dashboard’ menu.

  • This display applies only when you need the information to be displayed in a jiffy.
  • All you need to do is, rotate your write towards yourself and the secondary display will automatically light up.
  • More so, beneficial for sports enthusiasts and runners.

Step counter and sleep monitoring

  • So these features need not be explained all over again. As these features were present since the first version of Xiaomi Mi band, there are no enhancements in this department.
  • The pedometer functionality also doesn’t need any explanation. The sleep monitoring works well, and the step counter is accurate.
  • The device syncs the data to your phone and which later on is transferred to the Mi account.

  • Here is a screenshot of the Mi Fitness app.
  • Where I slept, for 9 hours to be precise, but after waking up in the morning, there was no significant activity.
  • So, the app shows 10 hours and 52 minutes of sleep activity last night. Well, I can’t blame the Xiaomi Mi Band 3 for my laziness after all.

Water resistance

  • As per the claims, the Xiaomi Mi Band 3 can sustain a pressure of 5 atm which equals to the pressure at 50 m depth under water.
  • We tried to test their claims by soaking the Xiaomi Mi Band 3 in water for half an hour. And to our surprise, Xiaomi Mi Band 3 is harmless.
  • The watch worked just fine; there were no hiccups.
  • Apart from this, all the sensors were also working flawlessly.

  • But we still don’t recommend you to take this with you for a bath on a daily basis. And yes, keep it away from hard and salty water.

Other features

There are at present two releases for Xiaomi Mi Band 3. One is the Bluetooth version, and the other is NFC based device.

Check out the cheapest projector by Xiaomi.

We would recommend you to go for the NFC based device for quicker response. Furthermore, if you are on a smaller budget, you can also opt for the Bluetooth variant.
