DESIGN

The Mi Smart Band4 launched in India. It has all its electronics in a plastic capsule that fits easily into a silicone band. The display is on the capsule, and a single button is below the screen. On the base of the capsule, there is a 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 plug it in its charger.

The Band 4 capsule does not fit into the charger very well. It kept popping out before eventually slotting in, which was quite disturbing. This is the biggest design-wise weakness of this product.

The Mi Smart Band 4 is very comfortable to wear for long hours. If you wore it throughout the day and while sleeping at night you will never found it to be in the way. It also offers a secure fit.

The 0.95-inch AMOLED display of the Band 4 is a great feature. We didn’t have any issues while reading it under direct sunlight, although we found the font for notifications to be a bit thin.

The touchscreen and the capacitive button below the display are very responsive. We think the user interface of the Mi Smart Band 4 is good. You can swipe up or down to move through screens, which show details of our workout, notifications, heart rate, etc. We can also customize this list using the Mi Fit app on your paired phone. By swiping 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 it’s too slow.

PERFORMANCE AND BATTERY LIFE

The Mi Smart Band4 has tons 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. The biggest problem with this device was that most of the features were disabled by default and we had to manually enable them in the mobile app.

For example, sleep assistant, notifications, and the option to wake the display when you lift your wrist were all disabled when we started using this device first time. The last one, in particular, is such a basic feature that it really should be the default behavior. These settings are not very easy to find.

It’s important to note that when we enabled each one of these features, it gave a warning message informing us that battery life might be reduced because of it. However, potentially missing out on some of the Mi Smart Band 4’s best features is not a reasonable trade-off.

OTHER FEATURES

This band has an exercise tracking mode too. We used this band for our gym sessions and found it to be reasonably accurate. Its heart rate tracking feature was satisfactory too, and the results were pretty good regarding that the Mi Smart Band 4’s price in India is less than Rs. 2,500.

Sleep tracking data was accurate for most of the time except for the “time awake” metric displayed in the Mi Fit app.

This Smart Band is rated swim-proof and can track your swimming workouts too.

Xiaomi claims that it’s battery life is around 20 days. We used the device for a week and found that the battery went down to 63 percent in that time. If you enable all optional features 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.
