Umidigi A9 Pro test / review

Umidigi is a brand that is still unknown to the general public in Europe, but it is very active and offers many different models of phones, most of the time with features to stand out such as a larger battery, more memory, good frequency coverage, ... I find that Umidigi has always been a generous brand in this respect. The quality has unfortunately not always been there but I was right to persevere because the last Umidigi I tested got a good score.[b][b]This new Umidigi A9 Pro comes to position itself as a direct competitor of the Redmi Note 9 with a more aggressive price (a little more than 100€ at launch) and some differentiating elements like a much higher level of finish and a Sony camera. This Umidigi could therefore succeed where the Redmi has failed and become a credible alternative to Xiaomi which has long remained without credible competition in this price segment.[b][b][b][b][b]linkManufacturer web site: https://www.umidigi.com[b]linkSite where I have bought the Umidigi A9 Pro: https://s.click.aliexpress.com/e/_9H6t3f[b]

Structure of my tests

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

Timeline

11/11/2020 I bought the Umidigi A9 Pro for 96€ on Aliexpress[b]29/12/2020 after more than a month of waiting, I finally received the Umidigi A9 Pro, the test can finally start.[b][b]

Why this phone?

This Umidigi A9 Pro is the fifth Umidigi I've tested and I chose it because on paper it represents a credible alternative to Redmi Note 9. I could probably test more famous or more expensive phones but I always try to find some pearls for an audience that doesn't want to invest a fortune to buy a phone.[b][b]I was able to get the Umidigi A9 Pro for less than 100€ when it was launched, this is a very aggressive price positioning and yet I don't see any sacrifices in terms of hardware or features. So Umidigi seems to have found the right ingredients to make an interesting phone for an affordable price. This territory was until now reserved for Xiaomi.[b][b]I also like Umidigi's community approach where interaction is possible with the manufacturer, few manufacturers have taken up this kind of challenge.[b][b]

Unpacking

[b][b]The box of the Umidigi A9 Pro is almost anonymous, it is all white with an Umidigi logo. It contains the phone as well as a charger, a usb cable, a manual, a transparent soft cover, a needle for the sim drawer and a manual.[b][b]The contents of the box are nothing unusual but for this price, I didn't expect anything else anyway.[b][b]

First configuration

The Umidigi A9 Pro runs on a streamlined version of Android, the configuration procedure contains nothing more than what is needed to start the phone. So Umidigi will not try to force you to sign up for a cloud or any other service.[b]

Finish

[b][b]Phones sold at around €100 are usually made from plastic materials which are not always of good quality. I was surprised by the Umidigi A9 Pro because its level of finish is far superior to anything in this price range. The phone uses glass and metal and that really makes it look good.[b][b]The phone has been designed in a very classic configuration with the volume and on/off buttons on the right, the sim drawer on the left, a jack connector underneath with a USB type C port and a grille for a speaker.[b][b]The back is made of glass and has a smooth surface which is only interrupted by the photo sensor which is quite visible from the back of the phone. This type of finish reminds me of the Umidigi S3 Pro which had an excellent level of finish but this phone cost more than 250€. [b][b]The phone is delivered with a transparent soft cover that highlights the phone quite well and helps to reduce the difference in level between the back and the photo sensor.[b][b]The level of finish is much better than Redmi Note 9 and is quite comparable to a mid-range phone. [b][b]The volume buttons are located a little lower than on most phones, so I often made the mistake of turning the volume up instead of down. The volume buttons are separated by a space, so it's hard to tell them apart.[b][b]

Benchmark Antutu/3DMark

The Umidigi A9 Pro is an entry-level phone, so don't expect high performance. I scored 145,000 points with Antutu. This score places the Umidigi A9 Pro below Redmi Note 9. This is not a problem in itself as the difference is not huge and the Umidigi is sold at a lower price, so the price/performance ratio is pretty good.[b][b]The Umidigi A9 Pro shows some slowdowns when switching screens or starting applications but again this is perfectly predictable and quite normal in this price range.

[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.[b][b]The Umidigi A9 Pro is not a gaming-oriented phone, but it offers sufficient performance to provide an acceptable gaming experience for most games. 3D games will need to be set to a lower graphics level but the experience is not bad. PUBG Mobile works fine on the Umidigi A9 Pro but I've encountered some slowdowns in the fast movements and the loading of textures is quite visible but for this price, I find this Umidigi does very well.[b][b][b]

Network performance

Umidigi often produces phones compatible with a large number of 4G frequencies and this is again the case with the A9 Pro. The Umidigi A9 Pro is compatible with 21 4G frequencies.[b][b]

3G frequencies : B1 (2100), B2 (1900), B3 (1800), B4 (1700/2100 AWS 1), B5 (850), B7 (2600), B8 (900), B12 (700), B13 (700), B17 (700), B18 (800), B19 (800), B20 (800), B26 (850), B28 (700), B34 (TDD 2100), B38 (TDD 2600), B39 (TDD 1900), B40 (TDD 2300), B41 (TDD 2500), B66 (1700/2100)

Signal 4G (before december 2020)[b]The ability to pick up the network correctly is an essential element for a phone but it is only very rarely measured. To measure a phone's ability to pick up the network, I perform a large number of measurements on the same cells to be able to compare phones under similar conditions. The signal is measured in dBm, a value of -90dBm indicates a worse signal than -70dBm. These measurements are therefore taken under real conditions and not in a laboratory, they are not scientific but give a good indication of performance. [b][b]Network signal sensitivity rating

[b][b]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 have tested other Umidigi models before this one and so far only the Umidigi Bison has scored well in the network sensitivity test while all other models were at the bottom of the ranking. The Umidigi A9 Pro is fortunately close to the performance of the Umidigi Bison.[b][b]Out of 981 measurements I obtained an average signal of -94 dBm while with my test device I obtained an average signal of -90.4 dBm. The difference is not very important, it is in the middle. What is interesting, however, is that the Umidigi manages to manage the signal fluctuations better because I measured a difference of barely 2 dBm between the minimum and the maximum, whereas my test device generated a difference of 7 dBm.[b][b]On the following graph, the signal from the Umidigi produces almost a perfect roundness which shows the stability of the phone where the test device is subject to many fluctuations.[b][b]

[b][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

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

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]

GPS performance

[b]To test the quality of the GPS signal I use the Offline Maps application and I make the same train trip in pedestrian mode. Why? In pedestrian mode, the GPS does not artificially correct the signal to stick to the road, it has no markings, so you can see the actual position. I then use an application to measure the accuracy of the signal. Not yet available / tested[b][b][b]Top 10 - GPS accuracy ranking

Charging score : 37.05

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 Umidigi A9 Pro has a capacity of 4150 mAh and has discharged from 100% to 1% in 552.00 minutes with 100% brightness, it has discharged from 100% to 1% in 1562.00 minutes with 50% brightness. I obtain in this way an average discharge speed of 0.18% per minute with 100% luminosity and 0.06% per minute with 50% luminosity, the consumption is therefore 7.52 mA per minute with 100% luminosity and 2.66 with 50% luminosity. To be able to compare the efficiency of the phone and its influence on the battery, you have to compare the 7.52 (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 Umidigi A9 Pro has a capacity of 4150 mAh and has been charged from 1% to 100% in 112.00 minutes. This gives me an average charging speed of 0.89% per minute and therefore an increase of 37.05 mA per minute. To compare the performance of the Umidigi A9 Pro compared to other phones, you should use the 37.05 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 Umidigi often sells phones with an above average battery capacity, this is not the case for the Umidigi A9 Pro as the capacity is limited to 4150 mAh. I can't consider this a weakness because many phones are marketed with a battery of equivalent capacity, it's just that Umidigi used to use batteries with a higher capacity.[b][b]I charged the battery from 1 to 100% in 112 minutes, this is the fastest phone I have been able to test so far. The charging curve is quite curious as the charging is very fast at the beginning, it fluctuates a bit and then flattens out for a long time towards the end.[b][b]

[b][b]I obtained a battery life of 552 minutes with the screen brightness at 100%, which is an average score, I got about the same score with the Xiaomi Mi 10 Lite. By lowering the brightness to 50%, I obtained a battery life of 1562 minutes, which is also an average score that is quite comparable to other phones of equivalent capacity. Decreasing the brightness by 2 has the effect of multiplying the autonomy by more or less 3. The Umidigi A9 Pro has a maximum brightness above the average and this may explain such a difference, the brightness of the screen is therefore not linear, it is progressive.[b][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]

Hardware

Selfie / resolution : 24
Resolution : 48
Sensor : Sony Exmor
mm wide angle : 7.03 mm

The Umidigi A9 Pro is equipped with a Sony Exmor sensor but I have no information about the model. Umidigi often uses Sony sensors where many brands use Samsung or Omnivision sensors. These Sony sensors are however more expensive while the prices of Umidigi phones are rather competitive.[b][b]Unfortunately, Umidigi has not yet been able to exploit the potential of these Sony sensors because on most of the previous models I tested, the photo processing was not very good. This was moreover one of Umidigi's biggest weaknesses (along with the network sensitivity), if Umidigi could solve this problem, they could face Xiaomi on equal terms.[b][b]So I'm curious to see if this Umidigi A9 Pro will fill this gap.[b][b]Default app[b]The photo application of the Umidigi A9 Pro is simple and intuitive, giving quick access to the main functions of the camera.[b][b]The main menu consists of:[b]- Beauty[b]- Video[b]- Image[b]- Portrait[b]- Extra (giving access to Night, Panoramic, Pro)[b][b]It is possible to activate AI and HDR but not at the same time.[b][b][b]

Photoquality

Photo test / studio[b]

[b][b]For this first studio test I took photos in normal mode, night mode, Pro mode (photo above), AI mode and HDR mode.[b][b]In normal mode the photo is slightly underexposed but the cleanliness is good, there is a slight grain visible in the blue areas. [b][b]In Pro mode it is possible to compensate the loss of light to obtain a white close to reality, the sharpness is good and the depth of field better than in normal mode. The pro mode is able to deliver good photo quality for a camera of this price.[b][b]With AI mode, the photo processing does not seem very different from the normal mode and with HDR mode there is a loss of sharpness and not really a difference in exposure time. HDR mode is quite slow.[b][b]From a technical point of view, the photo sensor of the Umidigi A9 Pro is capable of producing good photos if one takes the trouble to use the pro mode. The other modes offer good quality for this price with a slight underexposure.[b][b]

[b][b][b]Photo test / sunny[b]

[b][b]I couldn't test the Umidigi A9 Pro with a nice sun because in winter even when the weather is sunny the light is not very strong. The photos for this test were taken in the middle of the afternoon.[b][b]As for the technical test in the studio, I took pictures of the same subject with different settings. What jumps out is the colouring of the photos, which is too reddish. This is a recurring problem at Umidigi because with the same sensors in other phones I don't have this kind of problem. It is possible to reduce this problem a little bit with the pro mode by using a different white balance.[b][b]I haven't found a magic formula to make the photos succeed every time I try, so you always have to look a little. Sometimes the normal mode produces correct photos, sometimes it is necessary to use the AI or HDR mode. The HDR mode should allow to give back a little brightness to the dark areas but you should not move because the HDR on the Umidigi is very slow and if you move, the sharpness after recomposition of the photos will be less good. The AI mode tends to exaggerate the colours which can sometimes give an unnatural result but to each one his preference.[b][b]This new Umidigi has some of the same problems as the previous models but for less than 100€, these defects are more acceptable than on other models sold for more than 200€ such as the Umidigi S3 Pro.

Audio quality

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]

Frequency Response[b]This test is intended to test the device's ability to correctly reproduce all frequencies. The white line in the middle of the graph is the ideal situation and the other colors come from tests on different phones. A deviation from the reference line indicates a deviation from the ideal situation. To see good sound at all frequencies, it is therefore necessary to get as close as possible to the reference line. Not yet available / tested[b][b]Dynamic Range[b]This test is designed to test a phone's ability to play sounds at different volume levels. Here too, the phones must be as close as possible to the reference.Not yet available / tested[b][b]Noise Level[b]This test aims to identify if the device under test is able to reproduce sounds without too much noise. A high score indicates a low parasite rate, a lower score indicates a higher presence of parasites.Not yet available / tested[b][b]Concert recording[b]The purpose of this test is to measure the recording quality of the phone when there is a lot of ambient noise. Since I don't have the opportunity to go to a concert every time I test a phone, I simulate the noise of a concert in a closed environment.Not yet available / tested[b][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]

Compare Umidigi A9 Pro 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.
