Bạn đang xem: Xiaomi mi band 4 review
In the world of activity trackers, nothing comes close to lớn the mày Band"s value. Cheaper than any Garmin or Fitbit tracker, even the most basic vivofit4 & Inspire, but still packing enough functionality, it also benefits from Xiaomi"s name recognition và is considered a serious choice, not a cheap knock-off no-name tracker.The most recent ngươi Band 4 pushes the value-for-money envelop even further thanks to a colored AMOLED screen, swim tracking, and music controls, which get added on top of the previous generation"s all-day activity, sleep, và heart rate tracking. Overall, the package is very attractive, but cracks are inevitably hiding below the surface, especially if you like spending your time in a pool.

|Price||$30-40 is cheap for what you get. Extremely cheap.|
|Display||It"s bright, visible outdoors, beautiful, và doesn"t affect battery life much.|
|Battery life||Even with auto-wake & heart rate measures every 30 minutes, plus some walks và swims, I can get about 10 days on a single charge.|
|Google Fit integration||One of the few trackers that transfer weight measures, sleep, và activities to Fit.|
THE NOT SO GOOD
|Interface||It"s not as customizable as I"d like. You can"t reorder or hide exercise types, or remove unnecessary items from the More menu.|
|Android app||Clunky and shows ads. It"s sad that you get ads even after having purchased the band.|
|Swim tracking||Worked well for the first two swims, then became completely unreliable.|
Hardware, what"s in the box
Xiaomi continues to lớn use the same size factor in its ngươi Bands: a small tracker that lodges firmly into a rubber band. No fancy clipping mechanism or band materials, the Band 4 is still as basic as it gets. The end result is understated — this isn"t a band lớn wear khổng lồ a formal dinner or your corner office job, but it"s nothing to lớn be ashamed of in casual settings.
The tracker is made of shiny đen plastic, with the 0.95" cảm biến display and trang chủ button on the front, & heart rate sensor plus two pogo charging pins on the back. The matte black rubber band uses a loop and video mechanism. It"s comfortable to wear & doesn"t get unbuckled for no reason.
Compared to the mày Band 3, the tracker is a little thicker và its đứng đầu glass is less curved. The charging pins have moved from the bottom side to the back, but you still need khổng lồ take the tracker out of the band to charge it, so there"s no real benefit to this change.

The most visible improvement is the beautiful AMOLED display. It"s bright, crystal clear even in daylight, và can be adjusted khổng lồ automatically lower its brightness at night. Functionally, it doesn"t do anything new, but it looks gorgeous và I now find the mày Band 3 old và cheap in comparison.
The display responds lớn swipes and touches, letting you swipe up/down through the different menus, tap to lớn select, & swipe sideways or tap the sole button below it to lớn go back. You can customize the order of the main menu items and hide some, but you have no control beyond that. For example, music controls are underMore & there"s no way khổng lồ bring them up to the top cấp độ to make them more accessible. Edit: As pointed out in the comments, you can get to lớn the music controls by swiping from left to lớn right on the home screen. Another annoyance is that the six trackable exercise types are phối in stone, so you can"t remove one or put your favorite exercise first.
Those are a few examples of the limitations you start noticing with the mi Band 4. It"s cheap, capable, but also rudimentary in some ways. The packaging too is very basic, but that"s fine. You get a regular carton box with the band, USB charging cradle, and manual. No fuss.

After installing the ngươi Fit app & signing in with an account, you hit the + button on the vị trí cao nhất right và proceed to địa chỉ cửa hàng your ngươi Band 4. The process is fairly easy & quick, as long as the band is plugged into a nguồn source và turned on.
Mi Fit is reminiscent of all of Xiaomi"s software — tiny fonts, light grey icons and text, lots of unnecessarily wasted screen space, & weird UX decisions. You can"t customize the trang chủ screen to show the metrics you care about, you can manually log sleep but not exercises (battery dead, forgot khổng lồ wear the tracker), and you need two or three taps to see your day"s workout(s).
Left: Home. Middle: Status (sleep, HR, weight). Right: My workouts (steps, workouts, calories).
Having used the phầm mềm for nearly two months now, I still find it unintuitive in many cases. The main large thẻ on the homescreen is one touch target, so tapping on sleep or heart rate or weight takes you to lớn the same My status tab and not each corresponding data page. Another oddity is how each tracked metric"s screen (sleep, HR, weight, steps, workouts, và calories) is organized. Some have a bottom tab lớn view their long-term history, the HR one doesn"t. Some display a daily graph by default, but the workouts one starts with the weekly graph. Most have a daily/weekly/monthly view, but the resting HR is only available in a monthly view. Those inconsistencies are mostly aleatory and they"re frustrating in everyday use when you tap, expecting khổng lồ find an option somewhere, only to be disappointed that it"s not.
Left two: Daily HR, monthly resting HR. Right two: Daily steps.
The one thing I did enjoy about the app are the added snippets below the sleep & steps graphs. They"re very good at conveying stats in a clear way, explaining your averages, whether you fell asleep earlier or later than usual, slept more or less, & how you compare khổng lồ similar users.

The phầm mềm also has aFriends tab for socializing with other mi Fit users, and aProfile tab where you can set goals and manage your mi Band 4. Beside activity tracking, the band can be a bare-bones smartwatch, thanks lớn call, SMS, and app notifications, event reminders, và alarms. It can also vibrate and notify you when you"ve been idle for too long. More settings are available in the app for lift-to-wake (with daily schedule), heart rate detection intervals, night mode (lowers the screen"s brightness), and auto-locking the band when you take it off.

This is also where you can download and set new designs for your band"s display. There are about 50 different options, varying from simple digits lớn cartoons and popular characters. Unfortunately, the ones you save to lớn your phone don"t all get transferred lớn the band — only the currently chosen one is. So even though the band lets you pick between a few designs from its own menu, you just get 3 basic designs & the last one you sent from your phone. I wish I was able khổng lồ save at least five designs on my band.

Tracking with the ngươi Band 4
I had been wearing the mi Band 3 on one wrist & the Fitbit Alta HR on another for a few months, khổng lồ double kiểm tra how they compare. While the numbers were never the same between the two, they were awfully close, & that"s stayed the same when I moved to the Band 4. Daily steps, heart rate (resting, during the day, during exercise), và sleep are 5-10% different from Fitbit"s, a good sign. Lớn me, the exact numbers don"t matter as much as the overall trend, day after day. If my step count goes from 4000 to 4500, that"s not important, but if it"s up from 4000 to 8000, that"s significant.
Mi Band 4 vs Fitbit Alta HR.
While passive tracking isn"t something I worry about a lot, I"m much more interested in active tracking, especially now that I"m swimming again. That"s actually one of the main reasons I bought the ngươi Band 4 và why I was so excited khổng lồ try it out.
Xiaomi took measures to avoid any wrong activations of the display with the water. After launching a swimming workout, the screen locks and requires a deliberate swipe up then down khổng lồ view exercise stats, and then a long tap-and-hold on the trang chủ button khổng lồ pause or stop tracking. In practice, it works well in the pool và I never noticed any weird vibrations or unwanted touches while swimming.
Left: Starting a swimming workout. Right: Stopping a swimming workout.
The first two times I swam with the mày Band 4, I couldn"t believe how good it was. I hadn"t expected a cheap $35 (approx.) band to be this accurate at swim tracking, but it nailed the entire distance perfectly. That"s even more surprising when you consider that I vị an underwater flip at one kết thúc of the pool but take a breath at the other end, that I swim 9 lengths (225m) in freestyle then switch khổng lồ a backstroke for the 10th length (25m), and that I take a super short break between each 250m round và do six in total (1500m).
Sadly though, every swim after that was completely wrong. One round (250m) became 427m or 479m, four rounds (1000m) became 1917m or 1979m, và so on. I even stopped all my shenanigans và tested a few continuous swims, all in freestyle and with underwater flips, no breaks, no backstroke, và still the results made absolutely no sense whatsoever. A hard reset và a manual choice of the length of the pool didn"t help in fixing this.
The total distance isn"t even a multiple of 25m, the pool length setting I choose, so did I swim khổng lồ the middle of the pool, teleport lớn the edge, then stop the workout? và how 10 laps would yield a swim length that"s not a multiple of 10 (929m) still baffles me. Something is clearly wrong with the hardware or with Xiaomi"s algorithms.
