Fone Arena The Mobile Blog Xiaomi launched the Mi Smart Band 4, successor of last year’s Mi Band 3 in India earlier this week.
The upgraded version features a larger color AMOLED full-touch display with a mini watch face, and features music and volume controls, stroke tracking with stroke recognition and more.
I have been using Mi Smart Band 4 ‘s new fitness band since last time, here is the review.
Box contents Design and Build The Band 4 has the same elliptical design as the Mi Band 3, but the touch button below the screen is slightly smaller than the predecessor.

Design and Build:———-
It weighs 22.1 grams, slightly heavier, but you won’t notice it since it’s just 2 grams more.
The dimensions should be same, since both the bands are similar.
It has a polycarbonate body, similar to Mi Band 2 and 3.
It has 5ATM water resistance, so you can even wear when swimming.
There is 3-axis accelerometer 3-axis gyroscope sensor, and Bluetooth 5.0 compared to Bluetooth 4.2 in the predecessor to connect to Android and iOS devices.
Since the Bluetooth chip is programmable, so it can store data even when it is disconnected from the smartphone.
Coming to the band, it is made of skin-friendly thermoplastic polyurethane and the strap is adjustable to extend from 155 to 216mm, depending on your wrist length.
Xiaomi says the Mi Band 3 and Mi smart Band 4 straps are interchangeable.
The holes in the band are perfect and the clasp made of aluminum alloy holds the band securely so it doesn’t come out unless you pull it out.
mi smart band 4 Display and features
You only get Black colored band in the box, but you can purchase different colored straps later.
Together you can see the heart rate which has flashing green LED lights, when you use it to measure heart rate then it will prove more useful for you.
You can also see the charging pins on the back, which has been moved from the bottom in the previous generations.
Display and features Coming to the display, the Band 4 has a large (120 x 240 pixels) AMOLED 24bit color touch screen display with up to 400 nits brightness
Similar to previous Mi Bands, you can set it to turn on when you lift your hand, and the screen turns off in a few seconds to save power.
It still attracts fingerprints and is not completely scratch resistant since I can see some tiny scratches on the band.
When mi fitness band 4 will be available in India?
mi has launched its gadget Mi Smart Band 4 in world class business.
Touch screen is smooth, and the touch button below the screen acts as a back button.
I thank him for the 400 nits brightness, you have no external visibility issues like the Mi Band 3. Not too much trouble!
Even I had faced similar issues with the Mi Band 2.
You can raise or lower it from level 1 to level 5.
Level 2 is enough for indoor, but you need to bump up the brightness to 4 or 5 to view the screen when you are in bright outdoors.
You can’t expect and ambient light sensor for auto brightness adjustment in the price range, but I felt the process of adjusting the brightness a bit tedious since you
need to scroll all the saw to the settings and adjust the brightness.
Wish there was an easy notification shade-like option to access brightness adjustment like the Amazfit smartwatches.
One good addition to the Mi Band 4 is music controls.
You can just swipe from left or right on the touch screen to view music control panel that lets you play, pause, skip tracks and also adjust volume when
you play any music or any kind of content like YouTube videos or podcasts when the band is connected to the phone.
The status option shows steps, distance and calories burnt.
There is also idle alerts count to show how long you have been sitting without moving.
Duration for this can be controlled using the app, which we will talk in the software part.
There is also heart rate option to quickly measure your heart rate in few seconds.
There is also weather option that shows when you connect the band to the phone.
Next up is the workout feature that has outdoor running, treadmill, cycling, walking, exercise and pool swimming, and it is also has capable of recording 12 different data sets
including the pace of your swimming, stroke count, distance and more, and you can select the pool size from 10m to 200m.
I haven’t tried swimming features personally, so can’t comment on the performance.
Sleep tracking has improved, and it shows light and deep sleep as well as awake time as usual.. For workouts, it warns that routs won’t be recorded for running
or walking, if the band is not connected to the phone since it grabs GPS data from the phone due to lack of built-in GPS.
It fails to get GPS data from phone sometimes, and I have experienced this when running, so the distance might not be accurate.
It shows time, distance and pace for workouts like running.
You can press and hold the touch button to pause a workout in the middle, and resume it or stop it.
Here is my cycling stats that shows GPS data, total time, average speed, calories burnt, average speed, time for every 1km and heart rate zones.
You get similar stats for outdoor running and other workouts.
From the band you can also enable DND with an option for auto DND that is activated when you go to sleep.
There is also Alarm, Stopwatch, Timer, Find device that turns on alarm sound on the phone when it is connected to the phone over Bluetooth, Silent to put the
phone to silent, band display that lets you change the band’s watch face.
Heart Rate Sensor The Mi Band 4 uses LED lights and photo-diodes to illuminate blood vessel for a while and monitors the heart rate via the change of green
You can’t say this is 100% accurate, but heart rate recordings — both resting and active are decent.
It is almost similar to the smartwatches like the Verge Lite.
For the price this does the job perfectly.
You can use the button or use the app to check the heart rate.
It stores the data with date and time.
It take 5 to 10 seconds to measure heart rate and is not continuous, but you get continuous heart rate tracking during workouts, which will also drain the battery.
Software Xiaomi new features for Android and iPhone in Mi Fit app
Kept improving more.
The Mi Fit 4.0 that was released back in May brought new UI.
This shows the summary in a card on the homepage, it shows steps, sleep, heart rate and weight data.
Users can see detailed statistics by clicking on this card.
The new UI looks clean and minimal and is certainly a refreshing change.
When you go to profile and choose the Mi Smart band 4, you can see a lot of options, including option to change watch band faces.
There are lot of watch faces to choose from, and you can also set custom watch face that lets change the background by taking a photo or choose a
photo from the gallery to show up in the background.
There is also an app called Mi Band 4 Watch Face that lets you choose custom watch bands and export it to the watch.
It takes time, but it’s worth it if you want a nice band face.
You can only view one new face on the band at a time apart from the default ones.
Other features on Mi Band app Battery life Compared to 110mAh battery on the Mi Band 3, this has a 135mAh battery to compensate for the larger and brighter screen.
The company promises a 20-day battery backup.
I have been using it for about a month, and I have charged only once, since I don’t have the band always connected to the phone for notifications.
This might vary depending on frequent use of the display with increased brightness, use of heart rate monitor during workouts and notifications turned on.
There is a change in the charger, which now hold the core unit inside the box.
This is definitely a great improvement, since it firms sits inside the charger without any movement.
It shows the charging level when connected, and it takes about 2 hours to charge fully.
Mi Smart Band 4 is the price. …..
It ticks the all the boxes by adding things that were missing in the predecessor.
It has a large AMOLED color display with lot of band faces, improved measurement with additional gyroscope sensor, still has 5ATM water resistant and offers a good battery life.
The Mi Band 4 is available from Amazon.in and mi.com.
