The return of the Poco brand in 2020 was followed by many models that have positioned themselves as the smartphones with the most interesting price / performance ratio. Each model has thus established itself in its price segment with a model exceeding the competition in terms of performance. The Poco range starts with the M range (which represents the entry level) with phones like the M3 or the M3 Pro, then there is the X range (which represents the mid-range) with phones like the X3 or the X3 Pro and there is finally the F range with for example the Poco F3 which represents the top of the Poco range. The Poco range is therefore much easier to understand than the Redmi or Mi range. [b][b] On the occasion of the big promotional day of November 11, Poco is launching a new model of the M range with the Poco M4 Pro 5G. This new phone is launched barely 6 months after the previous model (the Poco M3 Pro) and while taking the same basics, the Poco M4 Pro will push the limits of the entry level a little further. The Poco M4 Pro offers more performance, more memory, and a few other changes that I will detail in this review. [b][b] The Poco M4 Pro will launch on November 11, 2021 with a promo you shouldn't miss. [b][b]
I test the phones according to a pre-established structure (see below) to provide you with as much information as possible. Unfortunately, this takes a long time. Some tests like network performance tests take several days and for photo tests I sometimes have to wait until the weather is suitable to take pictures in good conditions. I am therefore obliged to publish the tests step by step, so I invite you to come back if the test is not complete at the time of your visit.[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
The list below shows the prices for the Poco M4 Pro 5G from more than 50 sites around the world. If you are not satisfied with any price, you can subscribe to a price alert to be the first to be notified when the price drops.[b] No price available for this product (not yet or not anymore) [b]
helpThe above links are affiliate links from companies such as Amazon, Gearbest, Aliexpress,... If you appreciate my work, I would be grateful if you could purchase these products through these links. It costs you absolutely nothing but I get a small commission that allows me to buy the material I test. Thank you very much!
Timeline
11/02/2021: I was lucky enough to be loaned a Poco M4 Pro to be able to test it. Unfortunately, I will not have as much time as usual to take the test, but I will try to give you as much information as possible.[b]
Why this phone?
I have bought just about every Poco model that has been released since 2021 and so far Poco has never disappointed me. Poco has managed to establish itself as a benchmark in the market in a very short time, the miracle recipe is to offer maximum performance for the price. The Poco make performance more accessible and this performance is not intended only for gamers because the responsiveness of a phone is an important criterion for a very large audience. [b][b] Price and performance are therefore two essential elements in choosing a Poco, but the advantages do not end there. The Poco M4 Pro is also equipped with an enduring 5000 mAh battery, it runs under a Mediatek architecture which often results in good performance at the GPS level. 5G is also supported, most European frequencies are available. The Poco M4 Pro is therefore a fairly complete phone and it can easily compete with other big, well-known brands.[b]
Unpacking
Poco boxes are very easy to identify, few brands use the combination of yellow and black, this color combination gives a strong visual identity to the Poco brand. The boxes of other manufacturers are much more anonymous than those of Poco. [b][b] The Poco box contains the phone, transparent cover, Poco stickers, manuals, needle for sim drawer, USB cable and charger. The contents of the box at Poco are very standardized, no more is needed anyway.

First configuration
The configuration of the Poco M4 Pro follows the same path as other phones using MIUI 12.5 except that for the Poco brand, all attempts to register for Xiaomi services have been withdrawn. The configuration procedure under MIUI 12.5 is more graphic and apart from a few screens imposed by Google, Poco / Xiaomi has managed to make these screens a little more pleasant.

Finish
Xiaomi manages to launch countless new phones every year, their secret? The recycling! The Poco M4 Pro takes many elements of the Redmi 10 for its exterior appearance. The 6.6-inch screen takes up 84% of the space, a border around the bezel is visible, and the selfie sensor is visible through a punch in the middle of the top of the phone.
At the rear, there is a large black block as on other Poco but this block varies from one model to another but the M range is the only one to use the black block. This time Poco has opted for a horizontal black block completely integrated into the back of the phone. The rest of the phone uses metallic gradient even the back is made of plastic material that won't warp when touched. The back is perfectly smooth except for the block containing the photo sensors, it comes out a few millimeters as for the Redmi 10.
At the bottom we find an audio output jack, a usb type C port and one of the two phone speakers.
At the top we find the other speaker, an infrared emitter and a sound sensor.
On the sides we find on the right the ignition button (with fingerprint sensor) and the volume buttons. On the left we find the sim drawer with two locations (sim + sim or sim + sd). [b][b] Poco brand phones have never been considered a benchmark in terms of exterior appearance or level of finish but I find that this Poco M4 Pro offers a good level of Finishing off for an entry-level phone, the phone has a very functional / practical look and it's quite successful.

Specifications
[b]The information below comes from the Device Info HW application. The application provides detailed technical information about the tested phone. I tested the Poco M4 Pro in its 6Gb / 128 Gb version, you will find all the detailed characteristics in the following screens. [b][b] What I take away from these characteristics: [b] - the screen is the same as the Redmi 10 [b] - Mediatek architecture (cpu / gpu), it should lead to good gps performance [b] - 90z screen [b] - Samsung SK5JN1 sensor like on the Redmi 10 but it seems to have slightly different characteristics [b][b]

CPU / GPU Performance
CPU : MediaTek Dimensity 810 GPU : ARM Mali-G57 MC2 Memory (RAM) : 6 Gb Storage : 128 Gb
[b][b]The Poco M4 Pro runs on a Mediatek architecture for the CPU and GPU. The CPU is a MediaTek Dimensity 700, it is a priori the same as on the Poco M3 Pro but I see that the clock frequency is higher on the Poco M4 Pro. Poco are performance-oriented phones, even at the entry level. The Antutu test that will follow will give an idea of the in-game performance of this new Poco. [b][b] For the graphics part, the Poco M4 Pro is based on a Mali-G57 MC2 GPU, here on the other hand nothing new because this GPU was already present in the Poco M3 Pro. [b][b] Important note This Poco should in principle use a Mediatek Dimensity 810 CPU and not 700 but for some reason mine was running on a Dimensity 700 while the 810 should be even more powerful. My test will therefore focus on the 700.[b]
Benchmark Antutu/3DMark
I obtained a score of 295298 points with Antutu, this places the performance level of the Poco M4 Pro at the level of a Xiaomi Mi 11 Lite and it exceeds a whole series of entry or mid-range phones such as the Redmi Note 10 Pro. The Poco is where I expected it to be, it's an entry-level phone that tickles the performance of a mid-range phone. For example, it exceeds the Samsung Galaxy A52 when it costs significantly more.

Number of smartphones in the ranking:133 Position of this smartphone in the ranking:38/133
Note: this ranking only contains the phones I tested as well as a few others that I added for reference. [b]Gaming[b]To test the performance in game, I download the mobile PUBG game and evaluate the in-game experience, graphics level and depth of vision. This game is quite demanding and should help you evaluating the performance of a phone. The Antutu score already gave a good indication of what to expect from the in-game performance of the Poco M4 Pro. PUBG Mobile runs smoothly on the Poco and it does so even with a high level of graphics. The in-game experience is very good and over the 8 minutes of video I did not experience any slowdowns and the phone did not heat up. There are more powerful phones like the Realme GT for example, but the price / performance ratio leans very strongly in favor of the Poco M4 Pro /[b][b][b]
Network performance
The Poco M4 5G makes 5G more accessible to everyone, most European 5G frequencies are supported, so you should be able to use this Poco all over Europe.[b]
Choose your country to check if your phone is compatible:
The frequencies displayed below will allow you to see if this phone is compatible with your operator or if you will be able to use it in the country where you are going on vacation.
Signal 4G (from December 2020)[b]I decided to change the methodology for measuring the network because I noticed that the configuration of the mobile network changes over time. This makes it more difficult to compare phones because the conditions are no longer exactly the same.[b][b]To overcome this problem, I set up a device that captures 24 hours a day about ten parameters from the mobile network (ex: cell id, rssi, rsrq, snr, frequency,...). I then place the phone next to the device for 24 to 48 hours taking the same measurements so that I can compare them. [b][b] Overview of the phones tested with this methodology[b][b]

[b][b]I did not have the opportunity to take as many measurements as usual to assess the network performance of this phone but still managed to take 570 measurements and got an average signal of -96.78 dBm. With my probe I obtained an average signal of -93.71 dBm, so there is a difference of about 3 dBm, it is not a very important difference. The Poco therefore has good network sensitivity, it is located in the high average.[b][b][b]Download/Upload speed[b]To test the download speed, I have identified some 4G cells offering good performance where I test all my devices several times to see what download and upload speed they can achieve.[b]Top 10 - speed ranking in download 1.

Number of smartphones in the ranking:30 Position of this smartphone in the ranking:0/30
Note: the theoretical maximum speed of a telephone is often limited by the configuration of the mobile network and the congestion of the network at the time of the measurement. So maybe you could get a higher speed on another network [b][b]
Wifi performance
To test a phone's ability to receive the network properly, I take measurements near my router and then remotely (and always at the same place). This gives me an average in dBm where a value of -90 dBm indicates poorer performance than a value at -30 dBm.[b]

Note: I have a 400Mbps line and a modem capable of delivering higher speed, but I can never be sure how much bandwidth is available when doing a test. [b]
GPS performance
[b]To test the accuracy of the GPS signal, I use two positioning applications to evaluate the difference between the actual position and the position indicated by the phone. This test is done outdoors with nothing to obstruct the signal. An accuracy level of up to 3 meters can easily be corrected by an application (e.g. Google Maps).[b][b] Phones equipped with Mediatek GPS chips are often more efficient than others and this is confirmed once again with this Poco M4 Pro. The GPS accuracy is within 1 meter and besides the first connection is quite fast, I usually have to wait longer to get a signal. I also checked the frequencies used but found only one per network (E1, B1, L1).[b][b]Top 10 - GPS accuracy ranking 1. Oukitel C21 1m 2. Redmi 9a 1m 3. Doogee S96 Pro 1m 4.

Number of smartphones in the ranking:28 Position of this smartphone in the ranking:8/28
Note: An accuracy of 3 meters or less can easily be corrected by a good GPS application. Phone performance also plays a role in how fast your display updates, so good accuracy could be compromised by too slow a display. [b]
Battery range
To test battery life I developed an application that measures the battery level minute by minute until the battery is empty. This application consumes about ten percent of the phone's resources and I do a test with 100 brightness. This test aims to reproduce a contemplative use of a phone (e.g. surfing the internet, reading articles, spending time on social networks). These results are not valid for intensive gaming/streaming use.
Capacity : 5000 Fast charge : Yes W max : 33 Range (100% brightness) : 634.00 Range (50% brightness) : 1600.00 Charging time : 123.00 Discharge speed (100%) : 0.16 Discharge score (100%) : 7.89 Discharge speed (50%) : 0.06 Discharge score (50%) : 3.13 Charging speed : 0.81 Charging score : 40.65
From March 2020, I replaced my subjective battery test with a technical test to better measure the real behaviour of the battery. Now I test the autonomy and charging time under absolutely identical conditions. I perform several measurements, so this test alone takes several days during which I cannot use the phone for anything else.
Battery life - methodology To test the battery life, I measure the battery consumption every minute in strictly identical conditions to be able to compare phones and also to allow you to evaluate your phone in the same conditions. I rule out any influence of applications that could interfere with the measurement. The autonomy is not linear, the battery sometimes discharges much faster at the end. This is a frustrating phenomenon but with my measurements, you will know if you need to find a charger quickly.
Battery life The battery of the Poco M4 Pro has a capacity of 5000 mAh and has discharged from 100% to 1% in 634.00 minutes with 100% brightness, it has discharged from 100% to 1% in 1600.00 minutes with 50% brightness. I obtain in this way an average discharge speed of 0.16% per minute with 100% luminosity and 0.06% per minute with 50% luminosity, the consumption is therefore 7.89 mA per minute with 100% luminosity and 3.13 with 50% luminosity. To be able to compare the efficiency of the phone and its influence on the battery, you have to compare the 7.89 (or 50%) score with that of other smartphones, the figure should be as low as possible.
Charging time - methodology To test the charging time, I always use the same charger with the same cable. I measure the charging time minute by minute to see the evolution of the charge as well as the charging speed. The charging speed of a battery is not linear, it is often faster at the beginning and slower at the end. The charger is compatible with fast charging.
Charging time The battery of the Poco M4 Pro has a capacity of 5000 mAh and has been charged from 1% to 100% in 123.00 minutes. This gives me an average charging speed of 0.81% per minute and therefore an increase of 40.65 mA per minute. To compare the performance of the Poco M4 Pro compared to other phones, you should use the 40.65 per minute score, this score should be as high as possible.
Important note: the charging speed is not always linear, the graph below gives you an indication of the battery behaviour.
The following table lists the phones tested with the technical battery test, they are ranked in order of efficiency. A higher battery capacity should logically result in a higher battery life but it is not always the case and it does not give any indication of the efficiency of a phone.

helpHow to read these figures? The battery capacity is an important element in determining the autonomy of a phone but it is not the only factor. A phone with a large battery may have a shorter battery life if it consumes more power. If I had to take an example from everyday life, I would use the universe of the car. If a car has a large fuel tank, it should be able to drive a longer distance unless its average fuel consumption is higher. The battery efficiency score works the same way, it should be as low as possible and represents the energy consumption of the phone. These differences in efficiency are often related to the brightness of the screen, large bright screens will tend to consume more energy and even if they have a large battery, their range will be shorter.
In summary
It took me 123 minutes to charge the battery from 1 to 100%, that's a great score that will put the Poco in the top 10 fastest phones I've tested. The 33W fast charge not only charges the battery fairly quickly but the Poco's charge is almost linear, the charging speed starts to slow between 80 and 90% but the last 20 percent only takes about 30 minutes.
I didn't have time to do my full runtime test, so I focused on testing with the screen 100% on. I got a battery life of 634 minutes, it's a very similar score to the Redmi 10 which uses the same type of screen and most likely has the same type of battery. Based on the Redmi 10, the battery life at 50% should climb to 1600 minutes. In the end, the Poco M4 Pro ranks in the middle with a moderately greedy screen. [b][b] With normal use, you should be able to last two to three days with a fully charged battery.[b]
Photo camera test
To test the quality of photos produced by a phone, I do a technical test (resolution, sharpness, chromatic aberration,...) in studio (identical conditions) to evaluate the technical part objectively. From the second half of 2020, I built my own laboratory to take completely objective technical measurements. I then take pictures in real conditions to see how the camera performs. I then evaluate these photos according to my criteria but I publish the photos so that you can evaluate the result according to your criteria.[b]
The Poco M4 Pro is equipped with a Samsung S5KJN1 main sensor that is also found on the Redmi 10, I note however some differences in the technical information of the sensor. The Redmi 10 did not dazzle me with its performance, I hope the Poco has managed to correct the situation with better image processing. The Samsung sensor is accompanied by a Sony IMX 355 ultra wide angle sensor, this sensor is present in almost all models of the Poco or Xiaomi range. [b][b] Gcam works on the Poco M4 Pro, so I will be able to compare the optimization of the Google application against the Xiaomi photo application. If the sensor is bad, Gcam will not be able to produce good photos, but if the sensor is not well optimized, Gcam can sometimes improve the quality of the photos.[b]
Photo quality
Photo quality (indoor/studio)[b]The studio test is carried out under the same conditions so that the results can be compared on an equal basis. I calibrate my lighting for each test to obtain the same brightness and colour temperature. This test is a preliminary analysis of the technical qualities of a camera. Most phones fail this test, so you should also read the results of the other tests in the following paragraphs.[b][b] Main sensor: Samsung S5KJN1
I have already tested this sensor on the Redmi 10 but I notice a small difference in the brightness, the photo taken by the Poco is a little better exposed. Overall I find the same characteristics as on the Redmi 10, the sharpness in the center is correct and the color temperature is a little too warm. I also tested the HDR and AI modes, you will find these photos in the gallery below. [b][b]
In this photo, the characteristics of the Samsung sensor are more visible. The sharpness in the center makes it possible to read the small texts on the Canadian banknote but this sharpness deteriorates at the periphery. Even if the texts are still legible, I can clearly see a blur line in the Hungarian banknote (bottom left) and the English banknote (top right). The photo is a little underexposed, this problem will also be visible in the outdoor photos. The colors are a little too warm, this will also be seen in the outdoor photos. [b][b] Ultra wide angle sensor: Sony IMX 355
This must be at least the tenth time I test this sensor and the remarks are invariably the same. Ultra wide-angle sensors have a lot of flaws, but the Sony IMX 355 doesn't fare too badly. The sharpness is not extraordinary but I have seen much worse, the deformations are very present but here too I have seen much worse and the photo is generally underexposed, here too it is the same with all the ultra large sensors angle. [b][b]
The loss of sharpness with this sensor is very noticeable on banknotes. The Samsung sensor offered enough sharpness to ensure good readability of the texts on the Canadian banknote, this is no longer the case with the Sony sensor and the problem worsens even more on the periphery. This smoothing will also be visible in outdoor photos. The colors are on the other hand more vivid than with the Samsung sensor, my technical colorimetry test will confirm this point as well. [b][b][b][b]Photo: technical test[b]I was inspired by industrial technical tests to create my own technical test to evaluate the technical quality of a camera. This test is an objective assessment of a camera's ability to render a scene correctly. [b][b]I test the following elements:[b]- centre sharpness, peripheral sharpness[b]- colour fidelity based on 24 reference colours[b]- level of chromatic aberration[b]- dynamic range (ability to capture dark and light areas without loss)[b]- distortion[b][b]The technical evaluation may differ from the subjective evaluation as the feeling of a photo will be influenced by the processing provided by each manufacturer.[b][b] Main sensor: Samsung S5KJN1

[b][b][b][b]Outdoor photo quality[b] Main sensor: Samsung S5KJN1 The Google Gcam photo application works on the Poco M4 Pro, it is quite slow in use but allows you to take photos with a sometimes more extensive rendering than 'with Poco's default photo app. I will therefore take the opportunity to compare the rendering of the two applications. [b][b] Poco photo application: [b]
This photo was in the afternoon in November when the sun was already very low. I didn't use AI or HDR. Overall the photo looks pretty good if you look at it on a phone screen, the exposure is okay, the colors look okay too, and I don't have any areas that are too dark or too light. If I look at this photo on a computer screen with the photo displayed at 100% of its size, I find that the sharpness is really not sufficient to render the foliage decent. The colors are also warmer than they should be and I have a loss of detail in some areas. [b][b] Gcam photo application: [b]
I took this photo in the same place and at the same time with Gcam. The photo looks darker, the colors are darker, and the entire photo appears to be covered by a thin film of yellow. On the other hand, the level of detail is more important, it is necessary for example to compare the sky or the area with the leaves under the water in the lower left. The strength of Gcam lies in the optimization of the photos and this pays off here for the level of detail but on the other hand the exposure and the colors are less good than with the Poco photo application. [b][b] Poco photo app in RAW mode and correction: [b]
I took this photo with Poco photo app in RAW mode (Pro with RAW mode ), I corrected the exposure and increased the color saturation. I could probably have done even better by spending more time in Photoshop but this shows that the information captured by the Poco allows you to do interesting things if you take the trouble to take photos in Pro mode with the RAW option. . [b][b] In the following photos, you will find photos taken in several places in sometimes a little different conditions. When you see several photos of the same place, it means that I have tested the AI, HDR or night mode. As a whole this Samsung sensor is able to produce correct photos when the light is good, but as soon as the light drops, the photos are too dark and the colors take on a brownish tint. The sharpness also varies greatly depending on the light conditions. These photos somewhat confirm the technical verdict where we will classify the Poco M4 Pro in the average of this price bracket for photo quality. Gcam allows you to recover certain details from photos, but Gcam does not solve everything. [b][b]
15add_a_photo
[b][b] Secondary sensor: Sony IMX 355 [b]
The technical test revealed that the Sony IMX 355 was better than the main sensor on colorimetry and dynamic range, it shows quite well in this photo. If I limit myself to a phone screen, I find that sometimes the photos taken with this sensor are better than those taken with the main sensor. Unfortunately this is not the case in reality, the level of detail is much less good. As I wrote above, the photos produced by ultra wide angle sensors are never better than those produced with a wide angle sensor but this Sony stands out a word from the others by producing better quality photos than other sensors of its category.

Video quality
Stabilisation[b] Video stabilization is not often possible with entry-level phones because their performance does not allow them to smooth video quickly enough. The Poco M4 Pro offers a sufficient level of performance to stabilize videos at 1080p (30 or 60 fps). The stabilization is not perfect but it is sufficient to absorb a large part of the vibrations. The performance is therefore not only useful for games but we can also see the effect on video stabilization here.[b]Video normale conditions The Poco M4 Pro can shoot 720p or 1080P 30fps / 60fps, 4k resolution is not available. I have 3 videos to show what the sensor is capable of. The first video is shot in landscape mode at 1080p 30fps, the second uses the same basics but is shot from the Gcam app and the last is in portrait mode at 1080p as well. The brightness was not excellent on the first two videos and we can clearly see that the exposure level is too low, the videos are too dark. The third video was taken at a time when there was more sun and the result is much better. [b][b] The exposure jumps are quite noticeable, the fluidity is not always excellent and the focus takes time to adapt to the movement. These are pretty common things for entry-level sensors, so the Poco M4 Pro isn't a video champion but it's far from the worst.[b]Video low light[b]Not yet available / tested[b][b]
External audio quality
[b]This test is intended to give you an overview of the volume and sound quality during calls and when listening to music through the external speakers. [b][b] External speaker test The Poco M4 Pro is equipped with two external speakers, one above and one below the phone. These speakers can produce moderately powerful sound where highs are predominant. I got values above 80 decibels for the peaks of the soundtrack used, it is a normal volume in this price category. Volume / call quality test The volume of the listening speaker is a little below average, I reach 50 decibels without using the speaker. The sound quality is quite correct on the other hand. If I use the loudspeaker to receive a call, the volume rises considerably, sometimes exceeding 70 decibels. Here too the sound quality is quite acceptable although it is very focused on the treble.[b]
Audio quality (headphones)
To test the quality of the phone's audio output, I connect the device's audio output to a measuring tool, then play sounds on all frequencies and measure the differences between the original sound and the sound produced by the phone. In this way I measure the phone's ability to correctly reproduce all sounds.[b]
Analysis of the sound produced by the Poco M4 Pro via the output jack shows that the Poco M4 Pro covers most frequencies correctly, it presents a slight deviation in the highs which move away from the reference from 10khz. I think the Poco M4 Pro uses the exact same hardware as the Poco M3 Pro because I got the exact same results. The sound produced by the Poco M4 Pro is of good quality on all frequencies, it cannot compete with high-end phones but that is not its vocation anyway. [b][b]
The sound produced by the Poco M4 Pro is not among the most powerful because I get a lower sound level than the average with the sound volume at maximum . The advantage of a more controlled volume is that the sound does not present any distortion.[b]
Screen quality
To test the screen, I use a colorimetric probe that measures the color accuracy of a screen, as well as other parameters to see if a screen is able to correctly reproduce an image. I also test the brightness level to determine if the screen will be able to display an image in full sunlight.[b]
Screen size : 6.6 Resolution : 1080 x 2400 Ratio : 20:9 Type : LCD IPS % occupancy : 84 dE white : 1.8 dE red : 0.9 dE green : 2.8 dE blue : 0.3 dE jaune : 3.3 dE cyan : 1.5 dE magenta : 5.0 White temperature : 6090 Contrast : 1174:1 Brightness : 398
Colorimetry[b]
The screen of the Poco M4 Pro is an NVT-ts, it is the same type of screen as the Redmi 10. This screen displays a resolution of 2400 by 1080 with a frequency of 60 hertz by default but which can be configured to go up to 90 hertz. Like most Xiaomi screens, the factory setting is wrong. To obtain the best colorimetry, it is necessary to choose the standard mode and usually this is sufficient to obtain a good colorimetry. With the standard mode I got a delta E of 5 where I usually get a delta E lower than 3. To improve the colorimetry, you have to choose a cool color temperature in addition to the standard mode. With this setup, I get a delta E of 2.52. The temperature of the white is 6081 Kelvin, the temperature should have approached a little over 6500 Kelvin but the difference is not very visible to the naked eye. The blue hues are just a little behind.[b][b]Top 10 - ranking of the best screens by colorimetry 1. Xiaomi Mi 10 Lite 5g dE = 0.73 2. Xiaomi Mi 10t Pro dE = 0.83 3. Realme Gt dE = 1.17 4.

Number of smartphones in the ranking:52 Position of this smartphone in the ranking:22/52
Note: the colorimetric difference is measured in dE. After three, the human eye will perceive a colorimetric difference, so the dE should be the lowest. The tests were all carried out with a colorimetric probe. [b]Brightness / Contrast[b]The screen of the Poco M4 Pro is not very bright in its factory configuration. You have to activate the sun mode to increase the brightness. I measured a brightness of 398 cd / m² with my probe and with this level of brightness the readability of the screen should be good in just about all conditions except bright sunshine. Ideally, more than 500 cd / m² are needed for the screen to be perfectly readable under the sun. [b][b] I measured a contrast ratio of 1174: 1 with my probe, it is an average value for this kind of screen. The Poco M4 Pro is equipped with an IPS LCD screen, it would have had to be equipped with an Amoled screen to achieve really high contrast.[b]
Biometry
The Poco M4 Pro uses a fingerprint sensor on the side, this sensor works great like most Poco / Xiaomi models. 2D facial recognition is also available.[b]
Operating system
[b]The Poco M4 Pro runs under MIUI 12.5 out of the box, this version offers a more graphical experience for the configuration and brings some improvements compared to the previous version such as the possibility of using its phone as a desktop computer like Samsung Dex , the operating system is also lighter and consumes less power. It is also possible to install apps in a sandbox if you have doubts about the security level of an app. [b][b] MIUI also comes with a whole series of unwanted apps, these apps are completely harmless, just ignore them but they cannot be uninstalled. These apps never really bothered me but I know they irritate some users. The advertisement is also present with for example the security scan which is launched with each installation of new applications, these advertisements can be deactivated in the settings.[b]

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
[b]The Poco M4 Pro is exactly where I expected it to be, offering some of the best price / performance ratio without having to make too many concessions on everything else. It takes the basics of what we find in other phones in the same price range but rises in mass with its performance. Is this phone only going to be useful for gamers? No, clearly not, the performance will provide everyday comfort for everyone and the other specificities of the phone will meet the expectations of a wider audience. [b][b] In addition to performance, this Poco M4 Pro has other qualities. For example, it is equipped with a 90 Hertz screen with almost perfect colorimetry if the configuration is adapted (see description / video). It has good wifi sensitivity and allows downloading at very high speed. The battery offers good autonomy with a relatively fast charge. [b][b] It's on the photo part where I'm a little disappointed because even if it is able to take correct photos when the light is good, it is quickly put in difficulty when the light is less good. The photos are then too dark and lack detail. [b][b] Poco has succeeded again, even the main brand Xiaomi can not do better in the fight for the first place in the price / performance ratio.[b]Strengths[b]Performance CPU / GPU [b] Colorimetric screen [b] Fast charge [b] Screen 90Hz [b] Sensitivity and speed wifi [b] Fast GPS fix [b][b][b]Weaknesses[b]Medium quality photo [b] Screen brightness [b][b][b]Alternatives to this product[b][b]The Poco M3 Pro represents a slightly less powerful alternative to the Poco M4 Pro.
