We have in our hands a new flagship smartphone within those included in the Android One range, with large doses of design, triple camera. A fingerprint sensor integrated into the screen itself and battery of great autonomy.

We could ask for improved performance as a result of using a Qualcomm processor of greater potential, as well as a model that scaled its amount of RAM up to 6 GB, but neither should you try to turn the Mi A3 into a gamer’s phone.

The fact of implementing an HD + screen is something that we can ignore but without a doubt. The great absence of the MI A3 is found in the lack of support for NFC technology. Something that has been demanded for a long time by users most similar to the brand.

This considerably limits the use of the telephone in certain environments, such as identification, mobile payments, as well as other similar functions of loyalty cards. They start to become a reality, especially in Europe.

Availability and prices

Retail price: $ 239.99 (64GB)

The new Mi A3 from Xiaomi is the natural substitute of the previous generations Mi A1 and Mi A2 that have had such a good result in the market worldwide. Beyond the expected continuity of the new Android One successor, there is a lot of novelty in this new Mi A3 that we are going to tell you next.

First of all, The most basic version goes on sale from July 24 at a recommended price of $ 249 with 4 GB of RAM and 64 GB of storage.

The Mi A3 you can buy it in the physical stores that the company has in our country, as well as in the official Mi.com store of the company.

If you choose to acquire the superior configuration with the same amount of RAM (4 GB) and 128 GB of storage. You can reserve it in the authorized My Stores and in Mi.com as of July 24. Its estimated price is $ 279, that is, $ 30 more than the basic price.

You can find the two configurations with three different holographic finishes on the back in blue, pure white and gray, slightly varying the tonality when the light hits them.

Design, manufacturing, and usability

Both the front screen and the rear of the Mi A3 are curved and covered by Corning Gorilla Glass 5 material in order to guarantee resistance to drops and scratches, in addition to guaranteeing a terminal thickness of only 8.4 millimeters.

We highly appreciate the presence of a loudspeaker on its front to guarantee the certain audio quality, as well as maintaining the 3.5 mm mini-jack headphone jack to be able to use compatible headphones.

For usability purposes, Xiaomi guarantees in this Android One model the fingerprint unlock system integrated under the screen glass, offering good results for the short period of time we have tested it.

It seems that the area of fingerprint detection has been expanded by 15% compared to previous generations, improving the speed of response and the fact that you can place your finger on a larger surface to successfully achieve unlocking.


The screen size chosen by Xiaomi for the Mi A3 maintains the measurements of previous generations with an AMOLED type panel whose diagonal corresponds to 6,088 inches, in an already extended format of 19.5: 9 very consistent to facilitate its handling.

The specification sheet of the Mi A3 tells us that the resolution offered is HD + of 1560 x 720 pixels, a value lower than what the Mi A2 launched in July of last year offered. Which supported Full HD + at 1080 x 2160 pixels. Where the new model improves is in the nits with a figure of 530 compared to the pixel density of 403 of the previous generation.

Our contact with the Mi A3 has allowed us to see how the illumination of the screen gains integers when consulting in broad daylight, offering a greater dynamic range when it comes to viewing.


The processor that reigns in the Mi A3 is the Qualcomm Snapdragon 665. A model equipped with artificial intelligence capabilities to make it possible for the Mi A3 to improve the results of image capture, as well as its use with features such as Google Lens to recognize objects.

The processor is accompanied by 4 GB of RAM, with the possibility of choosing between 64 and 128 GB of storage. It is always possible to extend this figure aided by the micro SD memory card slot that Xiaomi keeps in its Mi A3.


During the presentation of the Mi A3. Xiaomi has indicated that the Mi A series with Android One has given them very good results since its arrival on the market, with more than 10 million units sold worldwide achieved by the sum of the Mi A1, Mi A2, and Mi A2 Lite.

With this premise, the Chinese brand has not hesitated to reach another milestone and be the first to present an Android One terminal with the triple camera sensor. Recently, we have seen the arrival of the Motorola Android One Vision, but with only two sensors.

This photographic set leads a 48-megapixel main sensor and a lens with a focal length of f / 1, 79 which is accompanied by another 8-megapixel wide-angle sensor with a focal length of 2.2. The third 2-megapixel sensor corresponds to the telephoto lens and is responsible for achieving the bokeh effect in the photos, giving a certain depth of field.

Integrated into the terminal screen and as a waterdrop notch. We locate the 32-megapixel camera with a focal aperture of f / 2.0 in the upper central part. Aided by the artificial intelligence of the Qualcomm chip. We can capture portraits in the panoramic mode so that no one is left out of the selfie.

The AI of the processor is responsible for joining the four pixels to form larger ones of 1.6 microns. Which facilitates the capture of a greater number of details in low light conditions.

Connectivity and battery autonomy

Not surprisingly, Xiaomi has dispensed with guaranteeing compatibility with wireless charging technology in order to maintain a reduced sale price below $ 300.

The same thing happens with resistance to water and dust since it does not comply with more advanced IP certifications that allow us to submerge the terminal underwater, as it happens with premium models.

As expected, we have a Type C USB connector for connectivity and battery charging. Which supports up to 18 watts/hour to speed up times. At this point, it should be noted the great capacity of it. Since it has increased to 4030 mAh. Which means that you can exceed two days of use under normal conditions.

The fact of having opted for an HD + panel instead of the higher resolution Full HD +, will undoubtedly also lead to improved autonomy times throughout the day. Especially if you are one of the users who spend much of their time watching series in streaming.

Against it, we must highlight the great absence of the Mi A3. Which is none other than the lack of support of NFC technology? Which we can carry out mobile payments among other associated advantages? Something that is becoming a factor to consider.


We are talking about the Mi A3 is an Android One model and as such. It comes standard with the Android 9.0 Pie version. The security that you will have the corresponding update once Android Q is available.

Another of the great advantages of these terminals is the approach they provide in the security section. With regular updates guaranteed for at least the first three years since its launch.

Do not look for a customization interface with MIUI 10. Since it is a pure Android One with a clean operating system layer that prevents the appearance of third-party application launchers or additional themes and customizations.

This makes the interface appear to be more agile than we are used to, although if you are a regular user of the brand. You will undoubtedly miss certain functions such as notifications and its status bar.
