Mi Smart Band

By SleekMart

Mi Smart Band 4 is an affordable fitness band from Xiaomi. With this, the fourth iteration of the Mi Band, Xiaomi has introduced a colour display and swim tracking, and still offers 20-day battery life. The Mi Smart Band 4 has an AMOLED colour display and lots of watch faces, which are nice to have. The Mi Smart Band 4 costs a little more than the Mi Band 3, but are its new features worth the asking price? We used it for a week to find out.

Mi Smart Band 4 design

Firstly, the Mi Smart Band 4 has all its electronics in a plastic capsule that fits snugly into a silicone band. The display is on the capsule, and a single capacitive button is below the screen. Secondly, the base of the capsule has the heart rate sensor and pins for charging. To charge the Mi Smart Band 4, you need to take the capsule out of the band and place it in its charger.

Moreover, this Band is comfortable to wear for long hours. We wore it throughout the day and while sleeping at night, and never found it to be in the way. The band also offers a secure fit.
In addition, the 0.95-inch AMOLED display of the Mi Smart Band 4 is a great feature. Text looks crisp and colours look nice too. We didn’t have any issues reading it under direct sunlight, although we found the font for notifications to be a bit too thin. The Mi Smart Band 4 doesn’t pop out of the band, which is good.

Further, the touchscreen and the capacitive button below the display are responsive. We think the user interface of this band is quite good. You can swipe up or down to cycle through screens, which show details of your workout, notifications, heart rate, etc. Moreover, you can customise this list using the Mi Fit app on your paired phone. If you swipe left or right, you’ll see the music player. The music controls worked well, but it did take a couple of seconds to load the name of the song and playback controls and we think that’s too slow.

Mi Smart Band 4 performance and battery life

The Mi Smart Band 4 has a lot of useful features such as the ability to track different types of workouts including swimming, sleep tracking, continuous heart rate monitoring, and notifications are displayed too. Our biggest problem with this device was that most of the useful features were disabled by default and we had to manually enable them in the app.
For example, sleep assistant (which helps get precise sleep data), notifications, and the option to wake the display when you lift your wrist were all disabled when we started using this device.

As for performance and tracking accuracy, we put the Mi Smart Band 4 through our standard set of tests. First we went for a 1km run measured using GPS on our phone, and then noted the distance measured by the Mi Smart Band 4. This wearable does not have in-built GPS, so its distance tracking is not likely to be very accurate.

Xiaomi lets you use your phone’s GPS to track the run if you allow Mi Fit access to your location. For this test we disabled Mi Fit’s location access. The Band 4 logged 1.3km as compared to the 1km logged on the phone. We tried the same test again after granting location access to Mi Fit, and the result was 1.11km logged. The second result is acceptable, but it’s more to do with the accuracy of the phone’s GPS as opposed to the accuracy of Mi Band’s tracking.

Subsequently, we also ran our standard step tracking test on the Band, in which we walked 1,000 steps and counted them manually. We saw that the Mi Smart Band 4 had logged 996 steps, which is excellent.

Health

Mi Smart Band 4 has an exercise tracking mode too. We used this for our gym sessions and found it to be reasonably accurate. Similarly, its heart rate tracking feature was satisfactory too, and the results were excellent considering that the Mi Smart Band 4’s price in India is less than ₹2,500.

Sleep tracking data was accurate for the most part, except for the “time awake” metric displayed in the Mi Fit app. We noticed that it would show time awake as 0 minutes even though we distinctly remember waking up multiple times through the night.
Likewise, Band 4 has a pretty decent heart rate sensor.

The band is rated swim-proof and can track your swimming workouts too. We were unable to test this feature during the review period but we did take the product into the shower every day, and it emerged unscathed.

Manufacturer claims that the Band 4 has a battery life of around 20 days. We used the device for a week and found that the battery went down to 63 percent (remaining) in that time. If you enable all optional features such as precise sleep tracking, the battery drains faster. Even then, you can expect the Mi Smart Band 4’s battery to last for over two weeks on a single charge.

Mi Smart Band 4 Companion app

Mi Fit app is of finest quality and it’s much better than the companion apps for several fitness bands priced higher than Mi Band lineup. Our thoughts on the Mi Fit app remain largely the same even now. We think it looks good, and largely makes it easy to find the data you need.

A couple of data points, such as historical data for exercise and running, were slightly hard to find because they weren’t in an obvious spot. However, this is a minor quibble.

We’d have liked to have the Band 4 displayed on the main screen instead of under the Profile tab. This would allow us to modify preferences and watch faces for the wearable more quickly. Speaking of which, there are lots of watch faces for Band 4 and we liked quite a few of them. There are a lot of watch faces. You can even create custom watch faces with photos from your smartphone.

Another nice touch is the ability to customise the vibration pattern for the Band. By default the wearable vibrates a bit too strongly for our liking. The device has the ability to show app notifications, and it even shows caller ID and previews for text messages, emails, and all third-party app alerts. If you get too many notifications, you should set a subtle vibration pattern on the Mi Smart Band 4. You can’t set a different vibration pattern for different apps or people.

Verdict

The Mi Smart Band 4 is another solid product in the Mi Band lineup. We loved its display, comfort, and workout tracking accuracy. Moreover, the Mi Fit app is excellent, and the ability to set custom vibration patterns for notifications is a godsend. However, the Band 4’s default settings leave several essential features disabled. Mi Smart Band 4 is one of the best low-cost fitness bands you can buy right now, and provides many times more worth than its asking price of ₹2,299.
