The new Xiaomi Mi Band 4 is out.
I got mine 3 days after the launch. And now I’m ready to share my thoughts on it. So here comes my Xiaomi Mi Band 4 review.
Released in mid-June (2019) this fitness band is proving to be a huge success. In just 8 days 1 million of fitness trackers were sold, as reported by Xiaomi’s global spokersperson Donovan Sung on his personal Twitter account. Is it much better than its predecessor Mi Band 3? What are the main differences between the two? Should you upgrade?
What it’s like the Xiaomi Mi Band 4? Is it the best fitness tracker for your needs?
Answers to all these questions you will find in this Mi Band 4 review.
[UPDATE] It’s February 2020. I’ve been using Xiaomi Mi Band 4 for more than 7 months. It’s working great. Its battery life is the same as good as promised. With my use I charge it once in 3-4 weeks. Right now it’s been 29 days since the last charge, and it’s still at 10%. I use it to track steps and sleep, as an alarm and timer daily. I take it off my hand only for charging.
The screen is mostly ok, in bright sunshine – hardly visible.
I haven’t really used Workout modes. I have tried them, but figured out that I don’t need them. It was strange to see that if you choose running mode, your steps during that run aren’t added to the total number of steps.
Overall it’s a great cheap fitness tracker I can recommend.

Xiaomi Mi Band 4 Review: First Impressions
The size. It’s not too small and it clearly isn’t too big.
It’s light and nice to touch. You can barely feel it when it’s on your hand.
The color screen. It really does make a difference.
My girlfriend has had the Mi Band 3 for some time. And it comes with a black and white screen, same like all previous Mi smart bands. The new Mi Band 4 on the other hand comes with a bigger and better color screen. While preserving same as great battery life of around 20 days and almost identical weight.
Bigger screen means you see everything better, plus you can see longer messages and notifications right on your band. And it’s also easier to navigate through the features.
The new Mi Band 4 on the other hand comes with a bigger and better color screen.
How about visibility in daylight? It’s ok. But remember that the screen is still pretty small.
This Mi fitness tracker has only one button. It’s right under the screen. It’s touch button and it’s flat.
Finding what you need is very easy, since there are only few features. Plus you can easily re-arrange them using the Xiaomi Mi Band app (Mi Fit). Some of the features can be activated and changed only using the app. Hence the band is suitable also for those with big hands.
Xiaomi Mi Band 4 Review: Setting Up
Inside the box there is a Mi Smart Band 4, a wrist strap, a special Mi Band charging cable / dock and a user guide.
Before you can start using your Mi Band tracker you will have to charge it.
Take it out of the strap. There are no any special methods. Just push it.
And plug it in the charging dock. The charging dock comes without the charger itself. So you will either have to connect it to your laptop’s USB port or to use your phone’s or camera’s charger.
It’s the USB 2.0, so you will not be able to directly connect it to new MacBooks.
How to Use Mi Band 4
After you have charged your Xiaomi Mi Band 4, you’re ready to set it up.
Go to either Apple App Store or Google Play Store to download the Mi Band application. Search for Xiaomi Mi Fit.
You need the app to set up your Mi Band.
Login using Facebook or register.
Choose Add device to add your Xiaomi activity tracker.
Afterwards you can use the app to change the settings of your Mi Band.
For example, to change the theme or set up an alarm.
To see information about your recorded activities.
To see your progress.
To learn more about how you are doing.
The app also tells you how you are doing compared to others of your age, sex and in your location.
How good or bad are you sleeping compared to them.
How much or little you weight compared to others of your age, sex and height.
And so on.
Xiaomi Mi Band 4 Review: Features
The Xiaomi Mi Band 4 is a basic fitness tracker.
It doesn’t have the same features like most of 100+ USD trackers. It doesn’t have GPS, for instance.
But still it’s so much more than just a watch.
First of all it’s a fully waterproof fitness tracker. Meaning you can go swimming with it. Not only it will survive it, but it will also identify different swimming strokes. Giving you ability to analize your performance later.
It does count steps and calories burned during the exercising.
It calculates the distance you’ve done (it’s approximate distance; recorded without GPS).
The band offers a Workout mode. When you use this mode and your phone is with you, your actual distance is going to be recorded. Because the band will use your phone’s GPS.
Activties in Workout mode: Outdoor running, Treadmill, Cycling, Walking, Exercise, Pool swimming.
It does show weather information from your phone.
And also call, message and app notifications, as long as they are turned on.
One of the features I, personally, love the most is the vibrating alarm clock feature.
One of the features I, personally, love the most is the vibrating alarm clock feature. First yime you have to set up alarm on your phone, using the Xiaomi Mi Fit app. After that you can turn off or on the alarm directly from your band.
You can use it as a stopwatch or timer, as well as a remote to switch between songs on your phone. In China you can use it to pay with Alipay.
The Mi Band 4 has a heart rate monitor feature.
The Mi Band heart rate monitor uses photoplethysmographic (PPG) heart rate sensor. It’s similar to one used by companies like Fitbit and Garmin. Does it provide accurate results? Not always. So, should you rely on it? As a medical device no.
And it also features a sleep tracker.
The Mi band sleep tracking feature will let you learn more about your sleep patterns and habits, plus will give you some useful tips.
Xiaomi Mi Band 4 vs Xiaomi Mi Band 3
Xiaomi Mi Band 4 vs Xiaomi Mi Band 3. What are the main differences?
The biggest difference is the screen. The Band 4 has an AMOLED color screen.
Skip the AMOLED part, if you don’t care about the technology being used. It will not matter for most users. But everyone will notice that it’s a color screen, not black and white screen. It’s an overall better screen and it’s also larger. By 39.9% larger than the one of the Mi 3 fitness band.
The Band 4 has a customizable first screen. On my band I have 45 different themes to choose from. While other sources say that there are 77 faces to choose from.
Thanks to its new six-axis sensor the Band 4 is better at tracking different swim activities. If you do swim, it might be one of the selling points for you.
The Band 4 also has a built-in micraphone. Which you can use to control Xiaomi’s AI assistant (currently available only in China).
Should you by the Xiaomi Mi Band 4?
Let’s look at the pros and cons.
- It’s cheap;
- It has a great battery life (in my case between 3 to 4 weeks);
- It’s customizable (screen and wrist straps);
- It has a great app;
- It has a lot of features for a simple fitness tracker.
- It doesn’t have a GPS;
- Its heart rate monitor isn’t going to be the most accurate one;
- Poor visibility in bright daylight.
Do you use a fitness tracker? Which one? Do you like it?
Book Your Trip Like a PRO
1. Book Your Flight
2. Book Your Accommodation
Booking.com, Agoda.com and Airbnb. I use Booking and Agoda at least a dozen times a year, and Airbnb – when looking for a long-term stay. My best tip is to ALWAYS compare the price. Sometimes the same hotel is cheaper on Booking.com, other times – on Agoda. Always compare the price!
3. Buy Your Travel Insurance
World Nomads and SafetyWings are two companies I can recommend. World Nomads offers some extra benefits, that will be important for those doing some higher risk activities, while SafetyWings is significantly cheaper. SafetyWings is only $9.25 / week.
