MagyarXiaomi Redmi 6 Pro (Mi A2 Lite) Smartphone Review
Xiaomi's newest additions to the Redmi series were introduced at the end of June this year. Customers are able choose between the more powerful Redmi 6 Pro and a lower-priced version without the name affix "Pro". Of course, both models are rather similar to each other, but there are still some significant differences between the Redmi 6 Pro and the normal version.
The Xiaomi Redmi 6 Pro has a Full HD+ panel with a resolution of 2280x1080 pixels and a display diagonal of 5.84 inches. A notch can also be found inside the IPS panel, housing the earpiece and the sensors, as well as the 5-megapixel front camera, which utilizes artificial intelligence for facial recognition. The phone's rear has a dual camera system, which also makes use of said AI features.
The midrange smartphone is powered by a slightly outdated Qualcomm SoC: a Snapdragon 625. It should still suffice for a competitive performance in the price range below 200 Euros (~$227), though. The permanently installed battery has a capacity of 4000 mAh.
The Redmi 6 Pro is available in three variants. The entry-level variant offers 3 GB of RAM and 32 GB of storage space at a price of about 130 Euros (~$148) in China. The import price was roughly 160 Euros (~$182) at the time of testing. Additionally, a version with 4 GB of RAM and a choice of either 32 GB or 64 GB of internal storage is available. Online shops offer this version in a price range starting at 180 Euros (~$205), which is a difference of approximately 20 Euros (~$22) in comparison to the price within China. Users looking to avoid importing the phone from China can instead purchase the Redmi 6 Pro locally as an Android One version.
Considering the street price of about 180 Euros (~$205) for the top model, the competition includes the HTC Desire 12 Plus, Honor 7C, Wiko View Max, Motorola Moto G5s Plus, and the LG K11.
Case - Convenient, High-Quality Xiaomi Phone
The Redmi 6 Pro's outward appearance is reminiscent of the Xiaomi Mi 8 design. The front of the case is made of scratch-resistant 2.5D display glass, which transitions into the 8.75-millimeter metal frame in a slight curve. The 5.84-inch IPS display is framed by narrow bezels at the sides. The top bezel is relatively narrow as well, causing a ratio of 80% between the display and device front.
The rear of the Redmi 6 Pro is made mostly of brushed aluminum and is available in five color options: red, pink, gold, light blue, and black. The vertically aligned dual cam setup protrudes from the case slightly, so that the phone wiggles during inputs on a flat table.
The build and material quality are on a really high level for a phone of this price range. Our only point of criticism was the slightly wobbly volume control buttons at the right side of the case. The pressure points are well defined and pleasantly crisp.
One-handed operation is possible thanks to the Xiaomi smartphone's low width of less than 72 millimeters. However, the phone is not all that pleasant to hold because of the slightly edgy metal frame.
Features - Still Using MicroUSB
Our test device's internal eMMC storage has a capacity of 64 GB, 51 GB of which is still available to the user after subtracting the space required by the operating system. Users in need of a higher capacity can expand the storage via microSD cards, but these cannot be mounted as internal storage. According to the manufacturer, the microSD card slot supports storage media of up to 256 GB. Since cards of that size are of the SDXC standard, even larger storage media should be accepted by the smartphone in the future without any problems.
The Redmi 6 Pro is still charged via a micro-USB 2.0 port on the bottom. Peripherals such as external keyboards or USB sticks can be connected via this port and USB OTG. Wireless transmission to other screens (Miracast) worked flawlessly in our test. In addition to a status LED for incoming notifications, the midrange smartphone is equipped with a fingerprint sensor and an infrared port. Currently, VoLTE is only supported for China Mobile, but this will hopefully be expanded to additional telecommunications companies as soon as an EU model of the Redmi 6 series (Mi A2 Lite) is released.
Software - Redmi Smartphone with Many Customization Options
The Redmi 6 Pro's operating system, namely Google Android 8.1 Oreo, is rather up to date at the time of testing – the same is true for the security patch level from July 2018. The manufacturer wraps the operating system into their own MiUI version 9.6 (stable), which we have already seen in the Xiaomi Mi 6X review, among others.
The MiUI is a strongly customized user interface that does not bear much resemblance to vanilla Android. In addition to visual adjustments, the system software offers many customization options.
Since the Redmi series has been designed for the Chinese market only for now, Xiaomi's own software MiUI does not offer any Google services such as the Play Store, or Google apps such as Gmail out-of-the-box. Instead, Chinese services and Xiaomi's own services are installed. However, a global version supporting Google services and offering additional system languages other than Chinese and English (German among others) will supposedly be released at a later time.
Alternatively, the sister model Xiaomi Mi A2 Lite with pure Android One instead of MiUI is available in Europe.
Communication and GPS - No LTE Band 20, but Triple SIM Tray
Xiaomi uses only Bluetooth 4.2 for the communication modules. The Redmi 6 Pro does not have an NFC chip for near field communication between mobile devices.
The midrange smartphone's integrated Wi-Fi module supports the IEEE 802.11 standards a/b/g/n (dual band), so it uses not only the 2.4 GHz frequency range but also the 5 GHz range. We measured a low attenuation of -34 dBm in close proximity to the router (Telekom Speedport, W921V).
The Redmi smartphone reaches good transfer rates of about 120 Mb/s in interaction with our reference router Linksys EA8500. Only the Motorola Moto G5s Plus is able to keep up with the Redmi 6 Pro here. The reception quality of the Wi-Fi module is good in everyday use and the signal is stable.
The Category 6 LTE smartphone with dual SIM achieves download rates of up to 300 Mb/s in the mobile Internet. Our test device aimed at the Chinese market is limited to local bands, so the LTE modem lacks access to LTE band 20 in the 800 MHz frequency range. The EU version (Mi A2 Lite) does not have these restrictions for Germany, though. Overall, the LTE modem supports nine LTE bands, which is not enough for a "suitable for globetrotting" recommendation.
The Redmi smartphone supports up to two nano-SIM cards at the same time. Thanks to the triple card slot, users do not have to do without an additional memory card while using two SIM cards simultaneously. Neither of the two cards is limited in its frequency range in dual SIM mode.
The Redmi 6 Pro supports the main satellite systems GPS, GLONASS, and BeiDou to locate positions. Outdoors, the satfix happens very quickly with an accuracy of about three meters. Even indoors, the Xiaomi smartphone is relatively fast in regard to positioning with an identical accuracy of three meters.
To assess our test device's location accuracy in practical use, we recorded a bike ride with the Redmi 6 Pro and with the GPS bike computer Garmin Edge 520 as comparison device simultaneously. The results of the midrange smartphone and the professional navigation device differ by about 110 meters, with an overall track length of about six kilometers. This is a satisfying result that should suffice for navigation during car or bike rides.
Telephone Functions and Voice Quality
The Xiaomi smartphone's voice quality is good and we did not encounter any problems in everyday use. There were no disruptive dropouts or reception problems during our test. Voices had a clear sound. The quality of the installed microphone was characterized as clear by our call partner.
Cameras - Dual Camera System in the Redmi 6 Pro
The main camera on the Redmi 6 Pro's rear has two lenses with an open aperture of f/2.2 and a phase detection autofocus. The 12-megapixel main camera has a resolution of 4032x3016 in the 4:3 format, while the second camera sensor (Samsung S5K5E8) has a resolution of 5 MP.
We already know the 12-megapixel camera's Sony IMX486 image sensor – it is the same sensor that was installed in the recently reviewed Mi 6X, with pixels in a size of 1.25 μm. In bad lighting conditions, the rear camera unit can be supported by a dual tone LED flash. Image stabilization can be done only via software (EIS), as there is no optical image stabilizer (OIS).
The photo quality is outstanding for a midrange smartphone at a price of 180 Euros (~$205), at least in bright lighting conditions. The photos' dynamic and details are both really convincing and the colors look rather natural as well. Even in low ambient light situations, the Redmi 6 Pro does a well enough job. However, there is visible image noise in low light and the pictures are increasingly out of focus.
Thanks to the second lens, bokeh effects can be created with targeted application of background blur. The quality of the results is not as high as the Xiaomi smartphone's photo quality, though.
Given the device's low price, the Redmi 6 Pro's 5 MP front camera is no selfie specialist. Pictures taken with the OmniVision OV5675 PureCel sensor have a tendency towards overexposure and colors appear too cool - overall, the photos are decent for a low-priced midrange smartphone, though.
The front camera records videos in 720p at 30 frames per second. The 12 MP rear camera records videos in the FHD resolution of 1920x1080 pixels at up to 60 FPS. The results are definitely presentable and the EIS does a decent job, but it cannot replace an optical image stabilizer.
We conducted further tests with the Redmi 6 Pro's camera under controlled lighting conditions. The rear camera's color representation was analyzed via ColorChecker Passport, displaying the reference color in the bottom half of each color patch. Our initial impression of the photos was confirmed. The Redmi 6 Pro's color representation is decent but is notably too dark. The white balance was done well, though.
The image sharpness in the photographed test chart was rather convincing, too. Even at the edges, the sharpness remains adequate. Colors gradients are displayed cleanly, but text on dark backgrounds is visibly frayed.
Accessories and Warranty
The box of the Redmi 6 Pro includes a modular power supply with a nominal capacity of 10 watts (5 V, 2 A), a USB cable, a SIM tool, and a quick-start guide. In addition, the manufacturer also includes a silicon case. Xiaomi has not listed special accessories in its online store so far.
Furthermore, TradingShenzhen adds an EU adapter for the wall sockets that are common in Europe. This adapter is not part of the standard delivery package, though, and it is a service feature by the lender.
The warranty is for 12 months. Please see our Guarantees, Return policies and Warranties FAQ for country-specific information.
Input Devices & Operation - Xiaomi Smartphone with FaceUnlock
The phone is operated via three on-screen buttons in the lower third of the display. Inputs on the 5.84-inch display are picked up accurately and quickly, even in the corners of the touchscreen. As introduced with the Mi 6X, "full screen gestures" can be used for navigation in the MiUI 9.6. These swiping gestures replace the on-screen buttons then. The gesture for the "Home" button is swiping upwards from the screen's bottom. Swiping inwards from the sides replaces the "Back" button, and swiping upwards from the screen's bottom and holding in the middle of the screen opens a list of currently running apps.
The fingerprint sensor integrated on the phone's rear unlocks the device quickly. The phone also does not take long to reactivate the display from stand-by mode. In addition to the usual unlock options, such as pattern, PIN, and password, the smartphone also supports facial recognition, which works surprisingly fast and reliably. Even in dark surroundings, the recognition rates are quite respectable, as long as the display emits enough light.
Sogou for MiUI is used as the keyboard layout. Users preferring a different keyboard app can download and install one from the Play Store.
Display - Good IPS Panel with Notch
The Redmi 6 Pro is equipped with a 5.84-inch IPS display in the 19:9 format, with a resolution of 2280x1080. The pixel density of 432 PPI is absolutely sufficient for everyday use and the image sharpness is really good.
The display reaches its maximum luminosity at 564 cd/m². We measured a similar value in the middle of the screen in automatic mode with activated ambient light sensor on a pure white background. The more realistic APL 50 measurement simulating an even distribution of bright and dark areas on the panel also had a result of about 560 cd/m².
Unfortunately, the Redmi 6 Pro uses pulse-width modulation for brightness control, which leads to fatigue for the user and can even cause headaches for more sensitive users. However, the frequency of 2500 Hz is relatively high, so health problems are unlikely even below a display brightness of 15%.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 2404 Hz | ≤ 15 % brightness setting |  |
The display backlight flickers at 2404 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 15 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 2404 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17365 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
The panel installed in the Redmi 6 Pro is really good for a midrange smartphone, even though the black level of 0.61 cd/m² and the contrast ratio of 908:1 are only average. Our test device had a slightly better contrast in the APL 50 test, during which we measured a ratio of 1015:1 with a black level of 0.55 cd/m².
The analysis with a spectrophotometer and the CalMAN software resulted in somewhat high DeltaE deviations to the sRGB color space, with values of 4.9 (color) and 5.3 (grayscales). In comparison: The ideal range starts at values < 3. At over 7700 K, the color temperature is significantly too high, resulting in a slight blue tint. The IPS panel covers the sRGB color space almost entirely.

The legibility of the display outdoors is pretty good in general. The screen content remains legible even in direct sunlight.
The Redmi smartphone has outstanding viewing-angle stability. No changes in color and only a very slight decrease in brightness are noticeable when the IPS panel is tilted strongly.
Performance - Old Snapdragon SoC, Good Performance
The Qualcomm MSM8953 Snapdragon 625 is a midrange SoC from 2016, manufactured in the 14 nm FinFET process. It has eight Cortex A53 processor cores, working at a clock speed of up to 2 GHz. The installed GPU is an Adreno 506, offering support for modern APIs such as Vulkan and OpenGL ES 3.1.
Supported by 4 GB of RAM, the midrange device delivers a good system performance. Apps also have pleasantly short loading times. However, there are some small, non-reproducible system stutters, especially during more demanding apps and multitasking.
The Redmi 6 Pro is at the front of the comparison field in our benchmark package, clearly ahead of the Snapdragon-450 and MediaTek rivals. The Snapdragon 625 can shine especially in AnTuTu and Geekbench. The Xiaomi smartphone also did very well in the system benchmarks.

* ... smaller is better
The speed of the 64 GB internal eMMC storage is outstanding for its class, leaving the competition with no chance. Especially when writing and reading small data blocks, the performance of the Redmi 6 Pro is in a league of its own.
Things look different for the speed of the microSD card reader, though. The transfer rates are decent but are not any better than the competition. The Redmi 6 Pro does not exhaust the possibilities of our reference card Toshiba Exceria Pro M501.

Games
The ARM Adreno 506 is a fast but slightly outdated GPU; nonetheless it supports all current APIs.
We took a look at some more-demanding games from the Play Store with the app GameBench. The first-person shooter Dead Trigger 2 and the racing game Asphalt 8 were displayed at a constant 30 FPS on highest settings.
The sensors and touchscreen reacted promptly during our tests, but the speaker is easily covered by the user's fingers.

Emissions
Temperature
In idle mode, the Xiaomi smartphone remains consistently cool, showing no signs of any hotspots. Under load, temperatures rise especially on the front of the device, sometimes even crossing the 40 °C mark. This is still acceptable, though, and it should not pose any problems for everyday use.
The waste heat inside the midrange smartphone is of greater interest to us. We tested the Qualcomm-SoC's temperature behavior with the GFXBench battery test, which repeats a test scenario 30 times in a row while recording the battery level as well as the frame rate. The Redmi 6 Pro's throttling is negligibly low under load during the demanding Manhattan test (OpenGL ES 3.1). The results show a rather constant frame rate with fluctuations lower than 1%, so performance drops under load are unlikely.
(±) The maximum temperature on the upper side is 40.6 °C / 105 F, compared to the average of 35 °C / 95 F, ranging from 21.9 to 56 °C for the class Smartphone.
(+) The bottom heats up to a maximum of 39.5 °C / 103 F, compared to the average of 33.8 °C / 93 F
(±) In idle usage, the average temperature for the upper side is 32.1 °C / 90 F, compared to the device average of 32.7 °C / 91 F.
Speaker
The Redmi 6 Pro is equipped with only a mono speaker at the bottom. At a maximum volume of 81 dB(A), the speaker is sufficiently loud and powerful, though. The sound quality is only suited for short video playback. As was to be expected, the sound is lacking bass entirely.
The sound tends to be dominated by the mid-frequency range, which is reproduced in a non-linear fashion. Furthermore, a dip in the high frequencies starting at around 8 kHz and in the super high frequencies starting at around 15 kHz is visible in the pink noise chart.
The Xiaomi smartphone comes equipped with a 3.5 mm headphone jack. Audio output via the headphone port as well as via Bluetooth shows no irregularities and is adequate for the price class.

Power Consumption
The power consumption overall is fine. During average idle operation, it is about as high as it is for other smartphones with a Snapdragon 625. Our measurements show a high fluctuation range for the Redmi 6 Pro, though.
As a result, the Xiaomi smartphone has a higher power consumption total than the Snapdragon 625 average and its direct competitors. Only the Wiko View Max has even higher power consumption.

Battery Runtime
The Redmi 6 Pro's battery has a capacity of 4000 mAh, and it had good results in our Wi-Fi test with the display brightness adjusted to 150 cd/m². Despite the somewhat high power consumption, Xiaomi coaxes almost 15 hours out of its midrange smartphone. Our battery test with video playback also did not suffer from the more inefficient power consumption. Even under full load during our stress test, the Redmi 6 Pro still lasted five hours. Merely the results in idle mode are not all that good.
The charging time amounts to about 2.5 hours, which is adequate considering the high battery capacity.

Verdict - Getting the Price Right
The Redmi 6 Pro is a rather well-made smartphone belonging to the low-priced midrange. The release of the Xiaomi Mi A2 Lite at the latest will introduce a serious new rival for the local smartphone competition in the price range below 200 Euros (~$227).
The Redmi 6 Pro offers a lot for a low price – however, we can only give a clear buy recommendation in Germany for the Android One version.
The Xiaomi smartphone has a good, bright IPS display with very stable viewing angles. In addition, it has an appealing camera, fast eMMC storage, long battery life, a triple tray for dual SIM, and biometric unlock features that work extremely well. Furthermore, the system performance as well as the outward appearance and surface feel of the case do not give away the fact at all that this smartphone costs only 180 Euros (~$205).
The quality of the mono speaker at the device's bottom was not very convincing, though. Xiaomi also could have installed a more up-to-date processor in its 2018 model. Local use is hampered by the low amount of supported LTE bands in the Chinese version.
