What you get

Xiaomi seems to have a winning recipe with its Mi Band series and the MI Band 4 is clearly their best band yet. Weighing only 22.1g, the Mi Band 4 is one of the most comfortable and lightweight fitness trackers on the market. The overall design hasn’t changed that much from its predecessors, however, it does sport a new 0.95-inch AMOLED display with a 240×120 resolution, 2.5D curves, and an anti-fingerprint coating.

The new display has 400 nits of max brightness, vibrant colors, and the new themes and screen savers provide the user with a totally new experience. In total, the display is 33% larger than the previous model. The capacitive button on the bottom has been adjusted to be flush with the display and is the only other noticeable change on the front of the Mi Band 4.

On the back, there is an upgraded 24/7 heart-rate sensor and charging port. It’s a very simple design that has worked for Xiaomi over the years and it’s not surprising that they haven’t made any radical cosmetic changes.xiaomi mi band 4


As stated earlier, the heart-rate monitor on the Mi Band 4 has been upgraded from the previous models and now has better accuracy. It can track various fitness activities such as Cycling, Battle Ropes, Running, Swimming, and Power Walking. It also features 5ATM waterproof rating, making it suitable for underwater activities up to 50 meters. Additionally, it has a sedentary reminder, event reminders, ability to unlock your phone, and more. 

You’ll need to start the activities manually as the Mi Band 4 doesn’t pick up on them automatically. It’s likely that Xiaomi chose a better battery instead of additional sensors. Additionally, the MI Band 4 doesn’t have built-in GPS but gets its location while paired via Bluetooth with your smartphone. For fitness tracking, the pedometer is used for tracking steps.

The Xiaomi Mi Band 4 uses the Mi Fit app to synchronize health and sleep data with your smartphone. It offers user-friendly progress graphs for fitness activities and sleep monitoring. It also syncs information with Google Fit. You can also use a third-party app called Notify & Fitness for Mi Band for additional features.

Other features the Mi Band 4 includes are SMS and push notifications. To set this up, go to the Mi Fit app, profile, and app notification setup. From there, you can toggle which applications you’d like to receive notifications. Another cool feature is the ability to control music through the Mi Band 4 while it’s connected via Bluetooth.


The Xiaomi Mi Band 4 is powered by a 135mAH battery and has an energy-efficient Bluetooth 5.0 chip. This gives you up to 20 days of battery life. The new AMOLED display requires a little more power, but it’s hardly noticeable. The MI band 4 takes approximately 2 hours to charge to 100%. 


With the updated battery life, heart rate monitor, and display, the Xiaomi Mi Band 4 is the most complete Fitness Tracker on the market, especially at its price point. It’s likely that you’ll spend more money on matching bands than you will on the band itself. Mi Band 3 straps also fit on the Mi Band 4. 

If this is your first time purchasing a fitness tracker, you won’t be disappointed, and if you have an older model, you’re seriously overdue for an upgrade.
