Xiaomi Mi Band Four overview: The large image

The Xiaomi Mi Band Three was probably the greatest worth health trackers of 2018, and the Mi Band Four goals to enhance on it in just a few key methods. It has a greater show and extra exercise profiles, however with these issues comes a slight worth bump, although the Mi Band Four continues to be considerably cheaper than different health trackers with comparable characteristic units.

The query is, are you actually getting something worthwhile by spending an additional $50 on a competing product, or ought to everybody run out and purchase the Mi Band Four proper now? That’s what we’ll reply in our Xiaomi Mi Band Four overview.

Let’s be sincere: None of Xiaomi’s Mi Band gadgets have ever been essentially the most well-designed items of tech, however the Mi Band Four is an enchancment. It’s nonetheless one of many extra generic-looking health trackers on the market with its easy black band and unassuming case, however the improved show saves the Mi Band 4’s design in my view.

It’s a 0.95-inch RGB AMOLED show this time round — an enormous step up from the Mi Band 3’s smaller black-and-white show. The 120 by 240 pixel density is sharp and the 400-nit brightness means it’s simple to see in direct daylight. It’s a touchscreen show, so that you’ll do most of your on-device navigation by means of faucets and swipes. Swipe up or down to pick out completely different modes or settings, swipe left or proper from the watch face to entry music controls, or swipe proper to return from a special display. You may as well faucet the capacitive button beneath the show to return. Simple.

The health tracker case simply detaches from the silicone band for those who’d prefer to swap it out for an additional band. And don’t fear, there are already loads of third-party Mi Band Four bands obtainable on Amazon. The Mi Band Four case is suitable with Mi Band Three bands, too.

The band that ships with the Mi Band Four is made from silicone and feels comfy. It’s not the very best high quality rubber you’ll discover on a health tracker — it’s slightly too inflexible for my style — however it will get the job executed.

The optical coronary heart charge sensor ever-so-slightly protrudes from the underside of the case, however not sufficient to go away a mark in your wrist after carrying it for just a few hours.

xiaomi mi band 4 review on charger charging cable bad not good

All through my testing, I didn’t discover any connectivity points between the Mi Band Four and my Pixel 3. Maybe that’s because of the Mi Band 4’s up to date Bluetooth 5.Zero help in comparison with the earlier technology’s Bluetooth 4.2 help. 

Under the center charge sensor sit two little pins for charging. When it’s time to cost, merely slide the Mi Band Four case into the included charging cradle and it ought to be topped up in about 45 minutes. A fast observe on the charging cable: I hate it. It’s about 4 inches lengthy, so it’s going to dangle from any USB charging port not sitting immediately on a desk.

The excellent news is you received’t must cost the Mi Band Four fairly often in any respect. With regular use, Xiaomi says the 135mAh battery will final about 20 days on a single cost. I haven’t been utilizing mine for 20 days, however I can inform you the battery is fairly nice up to now. I’m presently sitting at a 70-percent cost after a full cost final Friday, and that’s after three lengthy runs and the center charge sensor being on in 10-minute intervals. 

Health and well being monitoring

The Mi Band Four will hold monitor of all of the fundamentals: steps taken, distance traveled, energy burned, resting and lively coronary heart charges, and sleep. It doesn’t have a built-in GPS, so your distance metrics received’t be very correct for those who’re going out for a run with solely your health tracker. Nonetheless, it comes with a related GPS characteristic, so you may monitor your exercises with GPS for those who don’t thoughts bringing your cellphone.

Notably, the Samsung Galaxy Match doesn’t characteristic related GPS, although the Fitbit Encourage and Encourage HR each do.

One other space the place the Mi Band Four stands out is the variety of exercise modes. It may well monitor the next workout routines: treadmill, out of doors working, biking, strolling, pool swimming, and the generic “exercise” exercise. That won’t seem to be a lot, however its predecessor wasn’t capable of monitor pool swimming or generic workout routines.

Talking of pool swimming, the Mi Band Four can acknowledge 5 completely different swimming kinds and document 12 completely different knowledge units, like swimming tempo and stroke depend. It additionally carries a water resistance score of 5ATM.

I wouldn’t usually point out you could begin an exercise from the Mi Band Four itself (as an alternative of urgent “start” from the app), however you may! All different Mi Band gadgets earlier than the Mi Band Four relied on manually beginning actions from the app or from computerized exercise recognition, so this small tweak is certainly a welcome one.

I took the Mi Band Four on a number of out of doors runs and in contrast it with my Garmin Forerunner 245 Music and Wahoo Tickr X coronary heart charge strap. Although it doesn’t have as many sensors because the Forerunner, the Mi Band Four was truly fairly correct. Step counting and energy burned metrics from the Mi Band Four have been very near the Forerunner 245 Music’s metrics. The one main outliers throughout my testing have been distance and tempo metrics, however that’s as a result of the Mi Band Four doesn’t have GPS and I didn’t check the related GPS characteristic throughout these runs.

Coronary heart charge recordings — each resting and lively — with the Mi Band Four are respectable. I’ve connected just a few comparability screenshots on a run I took with the Forerunner 245 Music and Wahoo Tickr X.

Garmin Forerunner 245 Music coronary heart charge readings


It’s a bit exhausting to inform from the screenshots (the Mi Match app doesn’t show coronary heart charge recordings very nicely) so I’ll stroll you thru it.

  • Max coronary heart charge:
    • Wahoo Tickr X (management): 170bpm
    • Xiaomi Mi Band 4: 173bpm
    • Garmin Forerunner 245 Music: 176bpm
  • Common coronary heart charge: 
    • Wahoo Tickr X (management): 142bpm
    • Xiaomi Mi Band 4: 155bpm
    • Garmin Forerunner 245 Music: 145bpm

The Forerunner and Mi Band Four stayed fairly near the Tickr X chest strap all through the exercise. All three gadgets had an identical max coronary heart charge, although the Mi Band Four was on the excessive facet by way of averages. The Mi Band Four truly did a greater job of catching the slight dip on the ~10-minute mark, although it didn’t go almost as little as it wanted to: The Tickr X acquired all the way in which all the way down to ~55bpm whereas the Mi Band solely dipped all the way down to ~150bpm.

Each the Forerunner and Mi Band additionally caught the dip on the ~16-minute mark, however the Mi Band Four clearly glitched at that time. It flatlined for a couple of minutes, jumped again up at ~18 minutes, solely to flatline once more till ~21 minutes.

We see this stuff occur with wrist-based coronary heart charge sensors very often, so it’s not stunning to see it occur to the Mi Band 4. General, it offers you a good suggestion as to the place your coronary heart charge typically is, however don’t depend on it absolutely for higher-intensity exercises.

Sleep monitoring is one other one of many Mi Band 4’s strongest areas. It’ll monitor your deep/gentle sleep and time awake, and it’ll offer you a sleep rating from 1-100 by evaluating your knowledge to different Mi Match customers’ knowledge.


All through my time with the system, I haven’t seen any main points with sleep monitoring — the Mi Band Four all the time appears to report my time asleep and time awake fairly precisely.

Smartwatch options

For a tool this small and low-cost, Xiaomi was capable of pack various sensible options into the Mi Band 4.

Earlier than we get too far into it, I’m utilizing the Mi Band Four meant for areas outdoors of China, so my overview unit doesn’t help contactless funds with Alipay, nor public transportation funds. It additionally lacks Xiaomi’s Xiao AI assistant. For extra info on the Chinese language mannequin, head right here.

The Mi Band Four can relay name, textual content, e-mail, and nearly another notification you obtain in your smartphone. Notifications come by means of to the Mi Band Four immediately. You may’t reply to any of them, and because of the little show some messages could be exhausting to learn, however it’s nonetheless a pleasant characteristic to have.

I’m shocked at what number of customization choices Xiaomi included within the Mi Match app. You may’t discover a few of these little conveniences in each health tracker:

  • Vibration sample: Every notification kind could be programmed with a customized vibration sample so you may inform the distinction with out even trying on the display.
  • Schedule for auto display get up: You may set the Mi Band 4’s show to activate whenever you raise your wrist at sure hours of the day. Which means the system received’t burn your eyes accidentally whenever you’re attempting to go to sleep.
  • Night time mode: After sundown (or at your most well-liked time), your Mi Band 4’s display brightness can be lowered.
  • Don’t disturb: Many health trackers have built-in DND modes, however the Mi Band 4’s could be turned on even with out your cellphone close by. In the event you’re getting bombarded with notifications and wish them to cease, switching to DND mode could be executed in only some faucets.

The Mi Band Four additionally helps completely different watch faces. There are a good quantity of watch face choices obtainable within the Mi Match app. Roughly half of them are colourful digital faces, whereas the opposite half characteristic cute, big-eyed cartoon animals. To every their very own.

There are additionally built-in vibration alarms, a “find my Mi Band” characteristic for those who misplace it, on-device climate, and the power to regulate your smartphones music out of your wrist. I’ve discovered music controls to be notably useful when strolling round the home and listening to podcasts.

The Xiaomi Mi Match app

xiaomi mi band 4 review xiaomi mi fit app google pixel 3

Xiaomi’s Mi Match app is what you’ll use to pair the Mi Band Four to your cellphone and think about all of your exercise stats, in contrast to the Galaxy Match which makes use of a number of apps for system settings and well being monitoring.

There are three sections of the Mi Match app — exercise, pals, and profile — that are all fairly simple. Associates is the place you may join with different Mi Match customers to see their exercise and well being information, and the profile part comprises all of your private information, targets, and settings.

The exercise part comprises 4 sub-sections: standing, strolling, working, and swimming. Strolling, working, and swimming are solely used for manually beginning these kinds of actions out of your cellphone. The standing part is the place you’ll discover the present day’s actions and targets.


Additional studying

I don’t like how tough it’s to examine into your exercise or exercise historical past. There’s no button for it, so chances are you’ll end up tapping round till you stumble throughout it. You may entry your historical past by tapping the exercise card within the standing tab, swiping over to my exercises, tapping steps right this moment, then historical past on the underside of the display. As somebody who continuously checks into exercise development over time, it is a little cumbersome. 

When you’re there, the Mi Match app will show tons of knowledge, even all the way down to the small five-minute actions it data all through the day. 


In the event you’re a diehard Google Match person and may’t surrender the app for something, excellent news: You may sync your Mi Match knowledge with Google Match. When you join your accounts within the Mi Match settings menu, all actions recorded by the Mi Band Four can be despatched over to Google Match. Personally, I haven’t skilled any of the latest Google Match points others have, so simply know that your expertise with syncing Mi Band Four knowledge to Google Match would possibly range.

Don’t miss: Google Match information: Every part you must find out about Google’s health platform

Mi Match can also be suitable with WeChat for individuals who need to sync their health knowledge with WeRun.

For essentially the most half, the Mi Match app is a well-rounded, easy-to-use health platform (other than the benefit of checking exercise historical past). The app may benefit from much more social options and compatibility with different health purposes, and I did discover just a few bugs within the app all through my time utilizing it. General although, it’s completely serviceable in its present type.

Worth for the cash & the competitors

Right here’s the place the Xiaomi Mi Band Four actually shines. It’s obtainable within the U.S. for simply $40, lower than half the worth of the Fitbit Encourage HR and Samsung Galaxy Match, that are the Mi Band 4’s major opponents. That is an unimaginable asking worth for what you get, and I’ve no downside recommending the Mi Band 4 to anybody in search of a primary exercise tracker.

In the event you’re not a fan of the Mi Match app, possibly regulate the Encourage HR as an alternative. The Fitbit app is without doubt one of the finest on the market and supplies a extra refined expertise general. Additionally, the Encourage HR’s characteristic set is similar to the Mi Band 4’s, so it actually is determined by which model and ecosystem you’d like to purchase into.

Xiaomi Mi Band Four overview: The decision

Annually, Xiaomi provides extra options to its Mi Band lineup and retains the worth hikes to a minimal. With an improved show, extra train profiles, and a rock-bottom worth, the Xiaomi Mi Band Four squares itself away as probably the greatest low-cost health trackers of 2019. In the event you known as it the finest low-cost health tracker, I don’t know if I’d argue with you.

In the event you want an affordable health tracker or just need to improve from a earlier Mi Band system, it is best to significantly take into account the Xiaomi Mi Band 4. What do you must lose?
