Xiaomi Mi Band 4 Review

Shahriar Siam

The Xiaomi Mi Band 3 was acceptable, however the Xiaomi Mi Band 4 is competing for significance.

For not exactly the cost of two film tickets, a few tubs of popcorn and two supersized soft drinks, you could be getting dynamic with a shading show, pulse screen and an associated GPS. The band even packs swim following, and not at all like its antecedent, its screen is anything but difficult to see inside, and out.

The body of the band is not any more forcing, fitting in Mi Band 3 lashes, and it's additionally no less easy to understand, with a straightforward menu framework.

What the update brings, be that as it may, is a greater, level screen for less fiddly swiping, and a somewhat bigger limit battery, so the additional shading and splendor don't bring about more awful battery life - amazing, allowed the 21 days cited on a solitary charge.

Xiaomi is selling the Mi Band 4 now all inclusive. In particular, in the US it very well may be purchased on Amazon for $39.99, and in the UK, it's accessible through Xiaomi's legitimate store for £34.99. In case you're in Australia, it's accessible from both Amazon or the authority Xiaomi Store for AU$59.

There's likewise a more costly form accessible in China, however the main additional component it packs is NFC, and that is stacked up to empower installment benefits that aren't bolstered in the US or UK.

Design and display

The tracker is light on the wrist at 21g, in this way, by correlation with a smartwatch like the Amazfit Verge or the Samsung Galaxy Watch Active, we didn't see we were wearing it.

The front of the Mi Band 4's center unit is the touch screen just as a capacitive catch underneath it. Communication over these components is a mix of swipes and taps. Its underside is the place the pulse screen sits, close by a pogo pin connector for charging.

Concerning the tie, the basic clasp framework is secure, agreeable, and is produced using thermoplastic polyurethane. Accessible in dark, it probably won't appear to be a gathering on your wrist, however a scope of styles and hues can be gotten on the off chance that you look for old Mi Band 3 lashes (they play pleasantly with the Mi Band 4).

The screen on the Mi Band 4 is greater than that of the Mi Band 3, estimating 0.95 inches. It's additionally higher goal, and communication is better this time around as well, with less missed taps and swipes.

Perceptibility is additionally essentially better gratitude to the reality brilliance moves up to 400 nits. This implies inside or out, it's anything but difficult to see, and when joined with shrewd motions to wake it up with a wrist turn, it's the primary Mi Band gadget to feel like it could be a smartwatch substitution.

You can take the Xiaomi Mi Band 4 swimming or into the shower too as it's likewise waterproof up to 50 meters, much the same as the Mi Band 3.

Fitness tracking 

Step following on the Xiaomi Mi Band 4 counted pleasantly with different trackers in everyday use, and is consistently on.

On the back of the tracker is a pulse sensor that sits straightforwardly on your skin. Paradoxically, it isn't generally on, so it won't persistently be recording your pulse when you're approaching your day.

Rather, you have to initiate it to get a score through to your wrist and have it recorded in the Mi Fit application on your telephone. This should likewise be possible by starting up an exercise, which connects with consistent following for the length of your meeting and gives you how you're doing on the band's presentation.

You'll discover the tracker will record your separation when you're running as well, and works related to your telephone's GPS, for an associated GPS experience. For easygoing sprinters who wouldn't fret taking their telephones with them when making the rounds, this ought to be fine, yet in the event that you need something more lightweight, you'll need an across the board arrangement that the Mi Band doesn't offer.

The tracker additionally has modes for cycling and swimming, however we haven't tried it for both of those exercises yet. After longer than seven days of showers and a submersion test however, we can bear witness to its waterproofing.

You can start up exercises from the band itself. On the other hand, when we assessed the Mi Band 3, a telephone was required to dispatch instructional meetings, and this is a colossal success for the most recent adaptation. It even salutes you when you hit achievements like 1KM, which is a pleasant touch.

This all meets up to make Xiaomi's new tracker a fundamentally the same as looking piece of unit, however one with essentially more incentive for easygoing exercisers and contraption fans the same.

Our principle fuss with the tracker is that highlights like the stopwatch or clock can't be gotten to during an exercise. The primary screen is bolted to exercise observing, and this was especially disappointing for us during rec center exercises. Other than that however, we discovered almost no to protest about when given the deal cost of the Mi Band 4.

Specs and other features 

The Mi Band 4 highlights a 3-pivot accelerometer and a 3-hub gyrator. This is essential for step-following, yet in addition empowers the inestimable movement to-wake motion that gives the band the usefulness of a handy wrist watch.

The Band 4 likewise offers rest following, and gratitude to the thin and light weight structure we didn't see we were all the while wearing the tracker in bed. It estimated somewhat less profound rest than the Samsung Galaxy Watch, yet generally rest times were practically identical.

In contrast to more premium gadgets, it doesn't give REM rest subtleties, similar to some top-end Fitbit items or a devoted tracker.

The default show grandstands the time decent and obviously. There's additionally an action circle, outwardly showing how much exercise you've done today, there's a battery rate marker and the date.

You can likewise fire an assortment of warnings to your wrist, including calls, messages, cautions, updates and application notices, and these can be modified through the cell phone application.

App and compatibility

The Mi Band 4 highlights Bluetooth 5, and it works with telephones running Android 4.4 or more, or iPhones running iOS 9.0 or more. To get it associated and matched up, you simply need to download the Mi Fit application to your telephone from the App Store of Google Play Store.

Application set up is simple, and through your cell phone, you can modify the band, from downloading fun watch faces through to setting cautions and occasion updates.

The application additionally separates the information into days, indicating your resting design, step tally, pulse, weight (on the off chance that you decide to enter it physically) and the sky is the limit from there. The interface looks wonderful, however the UX is somewhat finicky. Catches aren't in every case clear, so we didn't generally have the foggiest idea what to press to get to what we were after.

So while the Mi Fit application covers the nuts and bolts and do what you need it to, with no point by point breakdown of information to keep you roused, and unintuitive UX plan, our most delighted in time with the Mi Band 4 was the point at which we were utilizing the gadget itself.

Battery life 

The Xiaomi Mi Band 4 games a 135mAh battery. We utilized the tracker for a little more than seven days with a few instructional meetings in there, and our battery perusing went somewhere near 32%. That counts up with Xiaomi's case of 20 days, however your last day-tally will rely upon your watch face, action following and general utilization.

Energizing the Xiaomi Mi Band 4 is pretty fiddly. You need to pop the tracker out of its band and opening it into an exclusive charger, so this won't work with a smaller scale USB or USB-C link. It charges rapidly, in any case, besides, you'll just need to energize it around 18 times each year if Xiaomi's 21-day battery life demonstrates valid over the long haul.


Pros Cons
Very cheap Only connected GPS
Slimline design No multitasking apps
Heart rate monitor Doesn't auto-stop tracking


The Xiaomi Mi Band 4 gets right what its antecedent got off-base - outside perceptibility is extraordinary, and you can begin exercises from your wrist, decreasing the band's dependence on your cell phone.
