Mi Band 4 Review: Best affordable smart fitness band


I might have spoiled the review with the title, but let’s get to the review to know why it’s the best budget fitness band and why you should go for it.

From the first Mi Band to the fourth generation, Xiaomi has come a long way. Having been used Mi Band 2 and Mi Band 3, I wasn’t very much interested in getting the latest one. But the AMOLED color display of Mi Band 4 changed my mind. Previous Mi Bands were just bland, with monochrome display, which made them less appealing. This time, Mi Band 4 had an attractive trait, a color display.

After using it for a few weeks, I wanted to give it more time since I wasn’t sure about their claim of battery life. So I waited more and tested it. Well, it’s been five months, and I highly recommend this band if you’re looking for a wearable gadget in a budget. Let’s see why.

Design and Build

I wasn’t an admirer of Mi Band 3. Black and white display, the strap was easy to remove, and the band would fall out of it easily. A friend of mine lost his Mi Band 3 because eventually it got too loose and landed somewhere. However, Xiaomi improved Mi Band 4 with hard to remove.

Talking about removing the band, I found it hard to remove, and then I got used to it. A little bit force and you can take it out. The strap itself is soft and is easy to put on. It is comfortable around the wrist, but tightening it might leave an impact, which is obvious.

The straps are available in different colors in Xiaomi stores as well as third-party makers. You can also change the ‘band face’ and make it the way you like. You can also use custom pictures as a band face in Mi Band 4.

AMOLED Display

The display of Mi Band 4 makes it appealing. It is bright, and outdoor visibility is better than previous ones and also beats other expensive competitors.

The colorful display AMOLED display comes with a touch screen and a capacitive home button, which lets you navigate through the interface.

The most exciting part of the display is that you are no longer stuck with the default band faces, unlike other smart fitness bands. Xiaomi finally adds plenty of band faces, which you can choose from the Mi Fit app. But I don’t find these band faces as exciting as I was expecting. I still like the default ones as they are well designed. But, you can also use custom images, like your photo or a scene.

Mi Band 4 has a lot to offer, keeping its price in mind. Here’s a list of the features that you can find in Mi Band 4:

Mi Band 4 supports notifications from different apps. You can enable notifications of the apps you use on your phone from settings in the Mi Fit app. Select the apps that you want to get notified about on your band, and Mi Band will tell about these apps. Different apps support this feature, but Emojis are not supported yet, and only stars “****” come up instead of that emoji. But, it’s useful to take a look at notifications while your phone is away or in the pocket.

Speaking of notifications, you can also set reminders and alarms from the Mi Fit app or from the band itself. You can also turn on a reminder if you’ve been sitting for too long; the band will sense that and will push notification so that you can move. It is known as ‘Idle alerts, ‘ which you can enable in settings.

You can enable particular app notifications for the band display and turn off for the other apps.

The band supports alarm notifications, WhatsApp, Instagram, Facebook, SMS, and Calls. The other system notifications can be enabled or disabled from the Mi Fit app.

The band also gets weather information from trusted weather providers and shows it to you on the band. It shows today’s weather and the forecast for up to four days of the week. It also shows location and weather conditions.

Heart Rate

There’s a heart rate monitor in Mi Band 4, and it calculates the heart rate continuously, time to time, or manually depending on the configuration from the Mi Fit app. To get ‘near to accurate’ reading, one should fasten the band slightly above the wrist bone and tap to start reading the heart rate. It shows almost accurate heart rate reading, but it is not a reliable device to read heart rate if you’re a patient.

This is one of the features that I use the most. I can easily forward and backward music, control volume, and play or pause a song. But one thing that bothers me is the activation speed, it isn’t fast. You have to wait few seconds and it’ll then enable music controls.
