Mibro Air: test / review
Category: Smartwatch

Mibro is a Chinese brand founded in 2015 which specialises in the manufacture of toys, including a whole range of robots for children. [b][b]Mibro has launched into the marketing of watches connected with this first Mibro Air. Why this change? Behind Mibro is the Chinese giant Xiaomi. It is therefore very likely that Xiaomi wants to use the Mibro brand to reach a different audience than the one already acquired by the Xiaomi brand.[b][b]The Mibro Air is therefore a first, but with the support of a company like Xiaomi, we can expect the watch to be more than a prototype full of bugs.[b][b][b][b]linkManufacturer web site: https://mibrofit.com[b]
How are my tests different from others on the web?

- I usually buy the devices with my own money, so price is just as important as you are!
- I keep the devices for at least a few weeks (sometimes more) to see what they are worth in real conditions.
- I answer (when possible) your questions to help you decide before you buy
- no one pays me to do these reviews, so I'm completely neutral and independent...
- My pages are not filled with ads

10/12/2020: I received the Mibro Air after a long waiting time (due to the covid and the large number of orders on the internet).[b][b]

Waarom deze smartwatch?

When I choose a phone to test, it is the purchase price that plays a decisive role in my choice. The same applies to watches. The Mibro Air is available for an introductory price of 28€, it is the cheapest watch I have had the opportunity to test.[b][b]What can I expect for a watch at 28€? On paper the Mibro Air offers the same functionality as a 50€ watch, it only needs GPS to be able to measure itself against a 100€ watch. If Mibro is supported by Xiaomi, it is very likely that the brand will follow the same kind of commercial strategy by offering low-priced products without too many concessions on quality.[b][b]

Structure of my tests

I test products according to a pre-established structure (see below) to provide you with maximum information. Unfortunately, this takes a lot of time. Unlike some sites where products are tested on a single day, I use the products I test for a minimum of a few weeks and sometimes even a few months. If the test is not complete at the time of your visit, I invite you to come back later or ask your question in the comment section below.


[b][b]The box of the Mibro Air reminds me of a Xiaomi product, the colour codes are more or less the same. The box contains the watch packed in a foam protection, a magnetic charging cable and a manual.[b][b][b][b]


The Mibro Air connects via Bluetooth to any smartphone using the Mibro Fit application. The Bluetooth connection is working properly, I have not encountered any problems. It is also possible to interrupt the Bluetooth link from the watch in order to avoid too frequent data exchanges with the phone, this possibility is intended to extend the battery life.[b][b]

Battery range

Mibro announces an autonomy of 10 days in normal use and 25 days on standby. I think Mibro was a bit too optimistic because after a few weeks of use, I get an autonomy of 3 to 4 days with normal use (1h to 1h30 of sport, some use of the watch features). By disabling the automatic ignition with each movement of the wrist it is possible to gain an extra day or two but I have never achieved 10 days of autonomy.[b][b]I find that the automatic ignition from the movement of the wrist is too sensitive, the watch really lights up very often and I suppose this explains why the autonomy is not as good as announced.[b][b]

Screen quality

The Mibro Air uses a 1.28 inch TFT screen. The screen is very bright and can be used outdoors without any problems. [b][b]In this price range you will not find an amoled screen but this small TFT screen does a good job because even if the blacks are not quite black, the contrast is good enough to ensure good readability on the screen.[b][b]Mibro has designed an operating system that uses a very sharp font and is large enough so that no reading effort is required. With watches such as the Amazfit, the messages on the screen are sometimes so small that they are not legible. I had absolutely no such problem with the Mibro Air.[b][b]The screen resolution of 240x240 is also in the middle range, you can see the pixels if you approach the watch but this has never been a problem for me.[b][b]The screen can turn on automatically every time you lift your wrist or you can turn it on from the button on the right. Wrist movement detection is very sensitive, so the screen comes on quite often if you decide to use this setting.[b][b]The Mibro Air may not have the best screen on the market but in this price range it probably offers one of the best value for money.[b][b]


Despite its price positioning, the Mibro Air has the same functionality as other products of this type.[b][b]The following functions are available from the main menu:[b]- message[b]I have received a few messages from Whatsapp and a few sms, you have to make sure you allow notifications for this to work.[b]- do not disturb mode[b]This mode is programmable, you can set the start and end times of the "do not disturb" mode, for example not to be disturbed by notifications in the middle of the night.[b]- activity summary[b]- sports (12 modes available)[b]- camera (triggering of the phone's camera)[b]I have not been able to get this mode to work, but I have tried it on 2 phones.[b]- heartbeat[b]- music playback control[b]This feature allows you to play, pause, skip to the next title and back to the previous one. I've tested it with Deezer, it works except that pausing to play moves to the next track rather than resuming playback.[b]- timer[b]- sleep measurement[b]- phone search[b]This function makes your phone ring if it is within range of your watch.[b]- stopwatch[b][b]


The reliability of the measurements is an important element in the choice of a watch and unfortunately the Mibro Air still has to correct some youthful illnesses because the results obtained are not always good.[b][b]- Heart rate measurement[b]I did several indoor cycling sessions comparing the heartbeats coming from my Polar H10 belt and the measurements taken by the Mibro Air. The differences between the two devices are significant.[b][b]Session 1 / Polar H10[b]Pulse max: 152[b]Average Pulse: 148[b]Session 1 / Mibro Air[b]Max. pulse: 102[b]Average Pulse: 90[b][b]Session 2 / H1° Polar[b]Max. pulse: 154[b]Average Pulse: 139[b]Session 2 / Mibro Air[b]Max. pulse: 104[b]Average Pulse: 91[b][b]I have never measured such a gap between the Polar H10 and a watch. Xiaomi does use good heart rate sensors on other products, so I assume that the measurement deviation is a software problem. [b][b]- Pitch measurement[b]With a normal walk, I measure a difference of 10 to 15% with reality. The Mibro Air has more steps than reality, I often get this kind of result with other watches. The measurements of the Mibro Air are therefore in line with what I have seen on other watches.[b][b]- Sleep measurement [b]I do not have the possibility to verify the accuracy of the data provided by the watch but the data collected seems quite realistic and is quite similar to what I have obtained with other watches. The watch gets trapped by your inactivity in the evening, if you watch TV after 9pm and don't move around much, this time may be counted as sleep time.[b][b]


To manage the Mibro Air on your phone, you need to download the Mibrofit application. This application is free of charge and offers many possibilities. I don't know if this application existed before the launch of Mibro Air but it is quite complete. [b][b]The main screen displays the main indicators, from there it is possible to get a detailed report on each type of measurement. [b][b]The activity screen allows activities to be triggered from the phone and by using the sensors in the watch to add heartbeats for example. I noticed that activities started from the watch are not included in the activities on the application, this is probably a bug.[b][b]The profile screen allows you to configure and customize the watch. There were only 4 dials to download at the time I tested the watch.[b][b]Overall the application is quite well designed, it is less complex than the one proposed by Amazfit but on the other hand it is clear that the translations were not made by a human being. The translations are sometimes incomprehensible and sometimes even amusing (ex: each time the screen loads, the application displays "desperate loading"). There is still a bit of work and youthful illnesses to be corrected but I imagine that with the Xiaomi support, Mibro will eventually reach the same degree of maturity as its competitors.[b][b][b][b]


The Mibro Air is compatible with all phones that can download the MibroFit application. I have tested it on several Android phones without encountering any problems, I don't have a phone under iOS to see if it's the same with Apple.[b][b]

Operating system

[b][b]The Mibro Air uses a proprietary operating system that is freely inspired by what can be found on other better known brands such as Samsung.[b][b]The main screen is configurable as on most watches, 3 screens are available on the watch and it is possible to download others through the Mibro Fit application. At the time of the test, there were only 4 additional screens available. However, it is possible to customize the dials to change their position information, for example. There is a personalisation menu in the watch but it doesn't seem to work, so you have to go through Mibro Fit. The personalisation screens of Mibro Fit are not easy to read because some screens are yellow on a white background, the contrast is not sufficient to read the information correctly.[b][b]The screen above the main screen gives access to several shortcuts:[b]- night mode[b]- do not disturb mode[b]- change of brightness[b]- battery indicator[b]- switch off the watch[b]In the night mode, you can set the times when you do not want to be disturbed.[b][b]On the left screen you can access the following widgets:[b]- activity summary[b]- weather forecast[b]- heart rate[b]- sleep analysis[b]- sport modes[b][b]The screen on the right-hand side allows access to the main menu of the watch, which is organised in a circle as on the Samsung Galaxy Watch 3. This menu allows all the watch's functions to be displayed on the same screen, but the watch dial does not turn as on the Samsung watch, so you have to turn the wheel with your fingers. This system works quite fast, you will probably sometimes skip a step and have to go backwards but the menu is quite easy to use.[b][b]The main menu contains the following options:[b]- do not disturb mode[b]- message[b]- activity summary[b]- sport modes[b]- control of the phone's camera[b]- heart rate[b]- music control on the smartphone[b]- settings[b]- timer[b]- phone search[b]- sleep ratio[b]- weather forecast[b]- stopwatch[b][b]The settings allow you to change the following options:[b]- automatic ignition when you raise your wrist[b]- standby time (before turning off the screen)[b]- information on the watch software[b]- bluetooth connection with the phone[b]- restart[b]- switch off[b]- back to factory settings[b][b]The bottom screen provides access to messages and notifications. You can receive notifications from the following applications: [b]- phone (calls)[b]- sms[b]- mail[b]- skype[b]- whatsapp[b]- facebook[b]You can enable or disable each type of notification from Mibro Fit.[b][b]The Mibro Air therefore offers a fairly complete range of functions, there is nothing revolutionary here, but the watch is very easy to use and the menus are logically constructed.[b][b][b]

Encoutered bugs

Compare Mibro Air with the others

I assigned a score of 1 to 10 for each test that determines the strengths and weaknesses of a product. I am using 0 for criteria that have not (yet) been tested. A score of 1 to 3 indicates poor performance (and yes, it does), a score of 4 to 6 indicates average performance, a score of 7 to 8 indicates good performance, and a score of 9 and 10 indicates exceptional performance. .
The score is calculated based on my measurements and when there are no measurements, it is a subjective opinion based on my experience.

The scores are not static, they change over time because the performance of new products changes and this must be taken into account.

Test / Review conclusion

Mibro had not yet marketed a watch, so this Mibro Air is a first. The launch price is ultra competitive and this undoubtedly gives an indication of the future positioning of the brand. For 28€ you can find other Chinese watches but the finishes will not be of the same level and the software of the watch will not be as good. With Mibro you can expect the range to evolve and the software to follow the same path, this will probably not be the case for watches of unknown brands in the same price range. As you will have understood, price is clearly the strongest argument for this watch.[b][b]Beyond the price, the watch has an interesting potential with its well-designed operating system and its Mibrofit application offering many possibilities. The Mibro Air unfortunately still has a few youthful flaws, the most important in my opinion is the unreliability of the heart measurements. I am not a great sportsman, I do at least 1 to 2 hours of sport per week and I am recording my progress. The heartbeat measurement is not reliable at all and that takes away some of the interest of the Mibro Air. If these measurements were correct, the Mibro Air would probably be one of the most interesting watches in this price range.[b][b]The battery life is not extraordinary either but at this price I can't do the difficult thing and having 3 to 4 days of battery life is not insurmountable. I think a different setting of the automatic ignition could greatly improve the situation.
