Foreword: Xiaomi Mi A2

Xiaomi Mi A2 is a new mid-range smartphone based on the Chinese Xiaomi Mi 6X. Key hardware features include an 5.99 Zoll Display, a powerful Snapdragon 660 system-on-chip and a dual main camera.

Compared to the Chinese model, the Mi A2 supports additional Molbilfunk frequencies and bands, including the ones that are common in this country LTE band 20, The smartphone is not delivered with MIUI, but with bloatwarefreien Stock Android, As an Android One certified device, users receive an 2-year warranty on system updates and an 3-year warranty on security patches.

Design, workmanship and delivery

Visually, the Xiaomi Mi A2 is strong at the Xiaomi Note 5 Redmire ajar. The Dimensions of the unibody metal housing 158.7 x 75.4 x 7.3 mmand Weight is pleasant 168 g, Due to the flat and at the same time rounded design, the smartphone looks much slimmer than comparable models. The smartphone is available in the colors Blue, gold and black.

Here you can buy the Xiaomi Mi A2.

The Xiaomi Mi A2 is constructed as follows:

front side is the 5.99 inch large display. Depending on the color choice, this is outlined in black or white. Striking are the rounded display edges, which contribute to the round look. Above the display is the narrow receiver in the middle. To the left, Xiaomi has placed the 20 megapixel front camera and the proximity sensor. To the right of the receiver are the LED flash and the notification LED, which, however, only lights up white.

Xiaomi Mi A2 front side with display

Through the unibody design, form the housing frame and the back a unit. The particularly slim case frame rounded off to the rear is equipped with a volume rocker and power button on the right side. The dual SIM slot is on the opposite side. The frame top includes one of the two microphones and an infrared transmitter. In the middle of the bottom of the frame is the USB-C socket. To the left of the USB-C socket is another microphone, to the right of the socket a mono speaker. An 3.5 mm headphone jack does not exist!

Xiaomi Mi A2 unibody back with camera

The back of the smartphone is equipped in the upper third with the dual main camera. Regarding this, the design of the Mi A2 has to be criticized. The camera protrudes remarkably out of the case so that the smartphone lies on the back, resting on the camera. Also in the upper third of the back is located centrally a circular fingerprint scanner. The plastic antenna strips are decent inconspicuously embedded in the back of the case.

The quality of workmanship is straightforward. The smartphone is flawless and clean. The control buttons sit in the housing without play. Of the What's in the box In addition to the Mi A2 includes a flexible protective cover, a SIM needle, a power adapter with EU plug (5V 2A), a USB-C cable, a USB-C to 3.5 mm jack adapter and a user manual.

Xiaomi Mi A2 Scope of delivery

Scope of delivery of the Xiaomi Mi A2

Display

The display of the Mi A2 triggers at one Diagonal of 5.99 inches with 2160 x 1080 pixels on. This results in a Aspect ratio of 18: 9 and a razor sharp Dot density of 403 PPI, Although this is not a Tri-Bezel-Less smartphone, it is Screen-to-body ratio at least 77%.

display measurement

Display measurements showed a maximum Luminance of the display about 381 cd / m², The measured Black Level is 0.224 cd / m², This results in a static Contrast ratio of 1: 1700.

The distributed over the display luminance is maximum 25 cd / m². From the Color and Grayscale presentation is with an average DeltaE from 5.2 departed. The color temperature is rather cool because of the increased blue content.

Display in everyday life

In everyday life, the display convinces by a crisp presentation and a strong color reproduction. The display also excels in terms of its Viewing angles, Particularly flat viewing angles lead to no color distortion or to any impairment of the color contrast. Although the maximum display brightness is not at the top level, it is sufficient to be able to read the display even in sunshine. What slightly affects the readability is the slightly reflective display glass.

Display settings and functions

In addition to the brightness adjustment, there are no settings options for the display. Also color adjustment options are missing. The display functions amount to one night mode, which filters the blue portion according to schedule, as well as one adaptive brightness adjustmentaccording to which the display brightness is adjusted automatically according to the ambient light.

Touchscreen

The touchscreen recognizes maximum 10 simultaneous inputs (Multi-touch). Inputs are detected precisely. Unintentionally occurring Ghost Touches have not made themselves felt in the test. The display and touchscreen are protected by Corning Gorilla Glass 5, a particularly scratch-resistant protective glass. After three weeks of use without protective film even micro scratches have failed. A special one Coating of the protective glass increases the lubricity on the touch screen.

Performance

Qualcomm Snapdragon 660

The system-on-chip of the Xiaomi Mi A2 forms Qualcomm Snapdragon 660, This mid-range processor, manufactured using the 14 nm method, consists of a total of 8 Kryo 260 cores together. The nuclei divide in turn two clusters on which 4 clocks with maximum 2.2 GHz clock rate and 4 with 1.8 GHz clock rate. The graphics unit the system-on-chip is one Adreno GPU 512, Compared to last year Xiaomi Mi A1 the Mi A2 is faster, especially with regard to graphical applications. Hardwareseitig demanding games such as PUBG Mobile are fluently playable.

The storage facilities amounts to one optional 4GB or 6GB Memory (LPDDR4X) and one optional 32GB, 64GB or 128GB flash memory, Despite compatibility, Xiaomi has opted not for fast UFS memory but for eMMC5.1 memory in terms of data storage. A memory expansion by MicroSD memory card is not provided!

Benchmark

With 131.128 achieved points in the AnTuTu benchmark test the Mi A2 meets the expectations. Even in several 3DMark test runs, which claim mainly the Adreno 512 GPU, the smartphone cuts a fine figure. Disappointing it is in the memory test. Especially the internal eMMC5.1 memory is well below expectations. A Read speed of about 165 MB / s and Write speed of 107 MB / s are clearly too low. Even with different measuring methods, no higher storage speed could be achieved. The speed of the memory is about 7150 MB / s still acceptable.

Performance in everyday life

In everyday life, the Snapdragon 660 delivers enough power smooth user experience to ensure. Apps open without delay, and even multiple apps open at the same time will not let the smartphone slow down noticeably. The user interface responds quickly and animations are displayed smoothly. The previously criticized memory speeds do not affect the everyday use.

Gaming

In the test, the Xiaomi Mi A2 was allowed the demanding Gaming title "PUBG" put. At high graphics settings, the mobile game is consistently fluid playable. Delayed loading of textures does not occur. After a 30-minute session, the hottest point is measured Temperature at almost 40 ° C.

User Interface

Depending on whether you look for the Xiaomi Mi A2 or the identical Xiaomi Mi 6X decides, the smartphone will come with Stock Android 8.1 or Xiaomi's in-house MIUI 10, based on Android 8.1. In the following, I will talk more about the stock Android interface of the Mi A2.

As an Android One smartphone, the Mi A2 has some advantages. Become through direct cooperation with Google Updates and security patches even faster distributed to the users. In addition, users of an Android One device get one 2 year warranty on system updates and 3 year warranty on security patches.

The user interface comes without annoying bloatware out. Except for a few Xiaomi apps are just the classic Google Appsincluding the Google Play Services preinstalled on your smartphone. If you do not want Google Apps, you can easily uninstall them via the App Manager.

The user interface is controlled via virtual Onscreen buttons, Unfortunately, the arrangement of the keys can not be determined individually. The disturbing thing is that the back button is not like most smartphones on the right, but on the left. It is not possible to hide the buttons completely and control the smartphone via gestures.

In practical use, the user interface proved to be extremely stable. The structure is clear and unexpected system crashes did not occur. If you like to stream movies and TV shows (Netflix) you do not need HD resolution. Although it is a certified Google mobile device, the Widevine DRM only with L3 supported!

camera

Also with regard to the camera equipment, a lot has happened. The dual main camera of the Xiaomi Mi A2 is made up of a 12 megapixel Sony IMX486 image sensor with f / 1.75 aperture and 1.25μm pixel size as well as one 20 Megapixel Sony IMX376 image sensor, also with f / 1.75 aperture and 2.0μm pixel size, together. Especially in low light conditions, the second sensor of the main camera should provide excellent results. At least in theory. The front camera also uses the 20 megapixel Sony IMX376 image sensor, but with f / 2.2 aperture.

Practical test of the main camera

Photo mode

In practice, the shots shot at day are quite on one ordinary middle-class level, Especially the color coordination the recordings convinced. Of the dynamic Range is as often restricted, but does not reach a level that makes recordings unusable. Of the level of detail the recordings are good overall. noise does not occur. Could also convince the sharpness distributionthat is preserved over the entire image area. The autofocus works mostly precise and fast. The shutter release time is low.

All full-resolution test shots can be found under this one article

Zoom

In contrast to Xiaomi Mi A1 is waived an optical zoom. Zooming is possible up to 8 magnification. With 2 magnification already shows a loss of detail and photos appear increasingly muddy.

HDR

The HDR mode makes worse recordings. On the one hand, photos appear even sharper and image highlights come into their own, while at the same time they make shots much darker shade many times unnatural.

Bad lighting conditions

Under bad lighting conditions, according to Xiaomi, especially the 20 megapixel "low-light sensor" points. If you switch to the manual recording mode, you can easily switch between the main and second sensor (low-light). Although the photos taken with the second sensor are more colorful and brighter than those of the main sensor, they also offer no significant increase in quality due to their strong image noise.

The best result is achieved by the 12 Megapixel main sensor in automatic recording mode. The shots shot with it are much less noisy and find a pleasant mix between the two manual sensor modes.

Bokeh

The Bokeh mode Mi A2 works mostly reliable. Especially people are extracted clean. However, objects do not always achieve a satisfactory result. The finer the object, the sooner extraction errors occur.

video mode

The Xiaomi Mi A2 is one of the few Xiaomi smartphones that comes with 1080p at 60 images-per-second record, tape. The maximum supported video resolution is 4k at 30 pictures-per-second, What was said about the photo-recording quality is also transferable to the video-recording quality. at good lighting conditions the recording quality is not objectionable. With increasing poorer lighting conditions Also decreases the recording quality accordingly. A clear image noise is noticeable and the autofocus begins to pulsate.

A electronic image stabilization is available. However, only recordings up to 1080p @ 60 are stabilized. Small to medium-sized Bildwackler be stabilized clean. To criticize is again the recording quality, With a bitrate of only 94 kbit / s the sound sounds slightly tinny.

Practical test of the front camera

Who likes to shoot selfies, will have fun with the front camera of the Mi A2. Both during the day and at night, the photo and video recording quality can be seen. The colors are natural and the level of detail is high. On Front-LED flash improves the recording quality in low light conditions.

The functions around the front camera are abundant. In addition to different Beauty Modes is there a Auto-HDR mode and one Portrait or Bokeh mode. Portrait shots succeed very well despite the purely software-based calculation.

connectivity

Telephony

The Xiaomi Mi A2 offers one Dual SIM slot (2x Nano) and supports the in Germany usual mobile radio frequencies as well as bands. However, the smartphone is not designed for global use. Here is an overview of the bands:

  • GSM: B2 / B3 / B5 / B8
  • WCDMA:B1/B2/B4/B5/B8
  • LTE FDD:B1/B2/B3/B4/B5/B7/B8/B20
  • LTE TDD: B38 / B40

Telephony and mobile surfing work smoothly with the Mi A2. The smartphone is extremely strong. Just as convincing is the voice quality. Spoken is transmitted without interference in both directions. By using two microphones noise is filtered.

Wi-Fi and Bluetooth

The smartphone supports Dual band AC WiFi (802.11 a / b / g / n / ac) as well as Bluetooth 5.0, The reception range and data throughput are decent both in the 2.4GHz and in the 5GHz network. The same applies to the Bluetooth module, which establishes and holds connections without errors.

GPS and sensors

The smartphone communicates with you to determine the position GPS, AGPS, GLONASS and Beidou, A GPS fix can be found quickly and the location can be determined to a few meters. Whether urban or rural navigation, a different position determination did not occur in several test routes. On E-Compass is available.

The others sensory equipment amounts to a proximity sensor, an ambient light sensor, an acceleration sensor, a gyroscope, a G-sensor and a Hall sensor. On Infrared transmitter allows to control it with appropriate app, such as the already pre-install Mi Remote App, TV and other devices with infrared receiver.

Fingerprint scanner

The back Fingerprint scanner Mi A2 convinces with its high recognition rate. The Entsperrzeit is however comparatively high. A safe face recognition is not implemented.

Audio

The Mono speaker gives a good sound, unless you set the volume too high. At the highest volume level, the speaker sounds shrill and tends to oversteer.

Who one Headphones or external speakers To connect to your smartphone, you need to use Bluetooth or the supplied USB-C to 3.5 mm jack audio adapter. An 3.5 mm headphone jack is not available as already mentioned! The sound via Bluetooth and the adapter is not objectionable.

Accumulator

The capacity of the non-replaceable battery is 3010 mAh, To come through the day with a battery charge is difficult even with moderate use. The average reached Screen-on-Time was included with medium display brightness just under 5 hours, Above all, the use of location services quickly drains the battery and clearly requires optimization.

The smartphone is charged via USB-C. Wireless Qi charging is not possible. A Quick Charge Although it is not listed in the specifications, with a Quick Charge 3.0 quick charger, the smartphone charges much faster. The Supplied charger Charges the battery 2 hours, On QC 3.0 charger Charges the battery in only 80 Minutes.

Summary

The Xiaomi Mi A1 was one of last year's Xiaomi highlights. With the release of the Xiaomi Mi A2, however, the hype surrounding the Android One smartphone has vanished. Unfortunately, the manufacturer has decided to completely cancel many functions. For example, the Mi A2 does without an 3.5 mm headphone jack, a memory card extension and also the optical zoom of the main camera. Some things have even worsened significantly. Above all, the reduced battery life.

Other things make the Xiaomi Mi A2 but also much better. So the design looks sleeker and also with Qualcomm's Snapdragon 660, the smartphone is very well positioned. Main and front camera are in the good middle class level, although the recording quality in direct comparison to the Xiaomi Mi A1 has not attracted too much.

Overall, the Xiaomi Mi A2 is a recommended mid-range smartphone in the 200 € price range. Anyone interested in the smartphone, should necessarily look at the other mid-range models of the manufacturer. Especially the Xiaomi Redmi Note 5 is a very hot competitor!

Looks great. I did not have the Snapdragon 660 on the screen yet, but the benchmarks I've just reviewed give an almost 70% performance boost to the Snapdragon 625. I'm already looking forward to the first camera samples.

The battery is really a pity. So I praise my note 5, which lasts much longer. Wanted to buy the Mi A2 for my wife, because of Android One. That's better with MIUI. Do you know if this is possibly fixed in future updates or if it is a hardware error?

Hello, after your review, I decided to buy the Mi A2. I really like the smartphone. The display is top and fast is the phone too. Only this Android OS bothers me a bit. Unfortunately, there are some features that I still know from TouchWiz. For every function to install an extra app, I also find suboptimal. Now my question. Do you know if you can install other firmwares on the phone? I would like to try this MIUI, but I did not find anything. I hope you can help me. Best regards and keep up with the reviews!

Hi Timo, because of your test I also bought a Xiaomi Mi A2 before 2 weeks. The smartphone is really great and I'm surprised what you get for the price. Even my Samsung at the time was much more expensive, can not compete. Thanks again for this great insider tip. ????

Can I confirm so too. Have the Mi A2 now since 3 weeks and am super satisfied with the smartphone. What's wrong with the WiFi I have not noticed. I have no disconnections and when I surf the web there is nothing to suspend the speed. What bothers me just a bit is the battery. He could last a little longer. But with the last updates that was already much better.

I bought the A2, the camera was crucial.
My question, how do I get the pictures on my PC,
because there is no software as with other providers.
A manual does not exist yet.

1) The battery is 4000 mAh ...... and not 3010mAh !! "The Xiaomi Mi A2 Lite is powered by a 4000 mAh battery and it runs and runs and ..."
2) "Depending on whether you are looking for the Xiaomi Mi A2 or the identical Xiaomi Mi 6X ...... .." what is a Xiaomi Mi 6X?
3) "If you do not want Google Apps, you can easily uninstall them via the App Manager ... .." is the GoogleSearchBalken on the home screen meant, certainly not, because this can not be removed ......... !! an impudence!
4) it would be normal or desirable, but it is not: the back button on the right, is really weird, (I'm not a leftist, right?) ......... even features like Xiaomis full-screen gestures to complete To dispense with the onscreen buttons, there is not on Vanilla Android 8.1
