Just a few weeks ago, Xiaomi introduced the Redmi Note 9S. Now Xiaomi is sending that Redmi Note 9 Pro Global into the race. The main differences are the support of NFC, one 64 MP main camera and fast 30 watt fast charging.

Techreviewer is part of the Mi Explorer program.

Design, workmanship and delivery

For many users, the design of a smartphone is just as important as good hardware equipment. Xiaomi's young brand Redmi is keen to provide the user best possible design experience to offer. This was shown by previously released Redmi models, which are particularly colorful and effective.

Redmi is pursuing a similar strategy with the Note 9 Series. The Redmi Note 9 Pro is in the colors "Glacier White", "Interstellar Gray" and "Tropical Green" available. Three colors that give the smartphone a very special elegance. For the test, the smartphone is in the color that is not yet available "Aurora Blue" before.

The Redmi Note 9 Pro is structured as follows:

On front awaits us 6,67 inch DotDisplay, which translates to "DotDisplay". The name comes from the placement of the front camera. The camera is punched out directly into the display. This solution of camera placement, also known as the "punch hole", is considered to be particularly space-saving.

The Redmi Note 9 Pro front with the 6,67 inch display.

The lateral ones Bezelthat surround the display fall with 3 mm (left, right and top) and 5 mm (below) pleasantly narrow. In the upper section there is the elongated and barely visible ear cup. A tiny one Notification LED (white) was integrated directly into the auricle. The display glass has a subtle curve (2.5D Curved) at the edges.

The display follows the transition to matted plastic frame. The color of the frame is matched to the back and does not immediately reveal that it is “only” plastic. There are numerous features around the frame.

The reflective Gorilla Glass 5 back of the smartphone.

The physical Control buttons are located on the right side of the frame and include a volume rocker and a power button. Both buttons are easily accessible with one hand. A first peculiarity is that Fingerprint scanner, which is integrated into the power button. The is opposite SIM slot, which holds two nano SIM cards and an additional microSD memory card.

The smartphone is pleasantly thin at 8,8 mm.

At the top is the Redmi Note 9 Pro IR blaster. This enables the control of television sets. To the right is one of the two microphones. At the bottom of the frame we would have the USB-C socket in the middle. Friends of wired headphones may use one 3.5 mm jack socket looking forward. The second microphone is located to the right of the USB-C socket. Again, we would have the media speaker next to it.

Now we come to the visual highlight of the Redmi Note 9 Pro. Front and back consist of particularly scratch-resistant Corning Gorilla Glass 5. The glossy back comes from the matt case frame. The smartphone appears elegant and dispenses with intrusive play of colors. However, the glossy back also has a disadvantage. Dirt and fingerprints are visible with the first touch.

It is tactile 165.75 x 76.68 x 8.8 mm large smartphone well in hand. Although the smartphone is mostly made of glass, it feels easy to grip. Added to this is the comparatively high level Weight of 209gthat gives a pleasant feeling. The so-called P2i nano-coating the back is water-repellent and allows use even in the rain.

The quality of workmanship is excellent. The What's in the box includes the Redmi Note 9 Pro, a USB-C cable, a SIM needle, a protective cover and a 33W quick charger. Unfortunately we cannot provide any further information on this, since we received our test device without additional scope of delivery.


The Redmi Note 9 Pro has one 6,67 inch display with 2400 1080 x pixels Resolution installed. With 395 DPI the display is pin sharp. The display type is IPS. This LCD technology is known for high color accuracy, wide viewing angles and good contrast.

Display measurement of the Redmi Note 9 Pro with the Spyder5 colorimeter.

In the so-called Cinema format (Aspect ratio of 21: 9), the smartphone is a bit longer and narrower than other models. So if you like watching movies on your smartphone, you can enjoy them in full.

Xiaomi specifies the maximum display brightness itself at 450 cd / m². Other features of the IPS panel are a contrast ratio of 1500: 1 and one 84 percent NTSC color space coverage.

display measurement

The measurements were initially carried out on the Factory setting. The color mode is set to "Automatic", the color temperature to "Standard". The following measurement results show that the white point differs from D65 and has a slight blue tint. But there is no need to worry, because many manufacturers want a white point beyond the D65. A slightly increased blue content ensures a brilliant white and a brighter display.

In this mode we were able to get a maximum Luminance of 420 cd / m² determine. The Black Level is 0.38 cd / m². This results in an average contrast ratio by 1100:1. A color measurements against sRGB and DCI-P3 result in an average Delta E of 4,99 and 4,74, respectively. Delta E describes the color deviation of two colors. An average Delta E between 4 and 5 is an acceptable value at the factory. Many smartphones come "out-of-the-box" with slightly oversaturated colors.

It will be interesting as soon as we "Warm" select the color temperature of the Redmi Note 9. Colors appear significantly warmer and we are approaching D65. The luminance is reduced to 400 cd / m² in this mode. Measurements against sRGB and DCI-P3 give a Delta E of 3,59 and 2,93, respectively. These are excellent values ​​for a mid-range smartphone!

The Illumination the panel is even. There are smaller (measurable) deviations towards the edges, which, however, do not exceed the scope of the usual.

Display in everyday life

The display of the Redmi Note 9 Pro was not only convincing in our measurements, but also in everyday life. The maximal display brightness does not reach a flagship level, but is enough to read the display even in sunshine. The Viewing angles is good. Particularly flat viewing angles do not lead to any visible change in color, brightness or contrast.

The only thing that bothered us is the slight shadow that the camera cutout casts. Depending on how you look at the display, it comes into its own more or less strongly.

Display settings and functions

The display is adjustable in many ways. A automatic brightness mode adjusts the display brightness to the ambient light. The ambient light sensor works quickly and precisely. 3 color profiles, 3 temperature profiles and a color wheel are available for color adjustment.

A battery-friendly Dark Mode is integrated in the system and can be activated via the display settings. There is also one on board Reading or night modethat filters blue light. The display is even TÜV Rheinland tested and has a corresponding Eyesafe seal of approval.

Support for is a rather unusual feature for a mid-range smartphone HDR10 Content. YouTube or Netflix can be enjoyed in HDR, even if the maximum display brightness is the limiting factor here.


The Touchscreen reacts quickly and recognizes inputs precisely. The Gorilla Glass 5 is also provided with a coating that ensures better gliding and reduces fingerprints.


Qualcomm Snapdragon 720G

One of the latest mid-range mobile processors is currently working under the hood. The Qualcomm Snapdragon 720G is a 8-nm chip with two fast Cortex-A76 cores (2,3 GHz) and four economical Cortex-A55 cores (1,8 GHz). The "G" in the name stands for "Gaming Performance". In combination with the Adreno 618 GPU, even current mobile games can be played without stutters.

The Redmi Note 9 Pro comes with one 6GB LPDDR4X Memory and a 64GB or 128GB UFS2.1 data store available. The data storage can be with a MicroSD memory card expand by an additional 512GB.


With an AnTuTu score of over 278.000 points, the Redmi Note 9 Pro is one of the faster mid-range smartphones. The smartphone also achieves good results in other benchmark tests, which mainly use the chip's Adreno 618 GPU.

The storage speeds also meet expectations. The LPDDR4X random access memory is with 20 GB / s pleasantly fast. The UFS2.1 data storage reaches an average Read throughput of 470 MB / s and Write throughput of 200 MB / s.

Performance in everyday life

The Snapdragon 720G offers enough power to offer a fluid everyday experience. There are power reserves for upcoming Android generations, even if they are somewhat smaller compared to current high-end devices.

The smartphone met our expectations in our stress test. Apps open quickly and remain in memory for a long time thanks to the lush 6GB of RAM. The change between the apps is smooth. Overall, the user interface reacts smoothly.


The smartphone does not have a> 90 Hz display or stereo speakers, but those who like to play mobile games will still enjoy the Redmi Note 9 Pro. As part of the Qualcomm gaming series the chip is optimized for gaming. Features like HDR, aptX and FastConnect WiFi improve the gaming experience.

The Adreno 618 GPU is high-performing and can even handle hardware-hungry titles. Graphically demanding games such as PUBG or Call of Duty are pleasant to play even with a high degree of texture. Thermal throttling doesn't bother the smartphone. The entire device remains pleasantly cool even under load.

User Interface

We have our test device with us MIUI 11 on the basis of Android 10 to get. Xiaomi has a user-friendly update policy. The manufacturer regularly submits new system updates and security patches. The Update to MIUI 12 has already been announced and is expected to be distributed in summer 2020.

MIUI is the in-house user interface that is used on all Xiaomi smartphones. The user interface is clear and easy to use with a little getting used to. The Google Play Store and other Google Apps are already preinstalled on the smartphone.

Via the integrated Theme manager the appearance of the user interface can be adjusted with just a few clicks. The security Center keeps an eye on the security of the smartphone and among other things manages the app permissions. When delivered, Bloatware is on the smartphone, but can be uninstalled in no time. It is a little more disturbing Advertising, which is shown in some (Xiaomi) system apps. But even this can be deactivated with a few tricks. Instructions for this can be found online.


The back adorns Quad camera system in a rectangular layout. The sensor system includes one 64 MP main sensor (f / 1.89), one 8 MP wide-angle sensor (119 °, f / 2.2), one 5 MP macro sensor (f / 2.4) and one 2 MP depth sensor (f / 2.4).

The Quad camera of the Redmi Note 9 Pro.

The main sensor is the 1 / 1.72 inches size Samsung S5KGW1 with 0.8 μm pixel size. He belongs to the ISOCELL Bright range and makes them Tetracell technology advantage. Two pairs of pixels of the same color (2 × 2 pixels) are created using Pixel binning combined into one pixel. This reduces the photo resolution to 16 MP. Theoretical advantages are a higher light sensitivity with accompanying noise reduction, an extended dynamic range and an increased image sharpness.

Practical test of the main camera

16 MP pictures

In normal photo mode, the smartphone takes pictures with 16 MP resolution. The pixel binning mentioned above is used here. Photos taken in good lighting conditions are pleasantly sharp, strong in the details and of course in the colors. The dynamic range is surprisingly large, so that light and dark parts of the picture show details as it were. Even the Auto HDR mode hardly ever has to intervene.

You can find these and other test recordings in full resolution under this Link.

64 MP pictures

To take photos at full 64 MP, there is a dedicated one in the MIUI camera app 64 MP mode. The photos taken in this mode hardly differ from the 16 MP photos. Convince yourself:


Instead of optical zoom, there is only one in the absence of a telephoto camera digital zoom. The enlargement is almost infinitely possible from 2x to 10x. With increasing magnification, the recording quality also decreases rapidly.

Macro and portrait mode

The 5 MP macro camera creates detailed, almost noise-free photos. The color matching is a bit cooler than that of normal photo mode. The autofocus, which is also available in macro mode, is an advantage.

Likewise portraits can be seen. In most cases, the motif is neatly separated from the background and the blurring effect is pleasantly subtle. The degree of blurring can be adjusted later. If the lighting conditions decrease, extraction errors may occasionally occur. Various filters (beauty and effects) can be activated in portrait mode.

Camera AI

The Camera AI is a nice gimmick to create more colorful pictures. Depending on the subject, different settings are activated. The dynamic range increases and colors are particularly rich.


The Redmi Note 9 Pro delivers acceptable recordings even in poor lighting conditions. The smartphone cannot keep up with current flagship models here, but measured in terms of price, the shots are on an upper mid-range level.

Above all, colors remain beautifully preserved. Details are also still clearly recognizable, even if particularly fine details are lost at the cost of noise reduction. A special night mode is available. In this mode, the image dynamics are increased and colors shine even more vividly.

Ultra wide angle

The 8 MP ultra wide angle camera fine with me. In contrast to the main camera, the images show a bit more noise and a slightly reduced level of detail. Distortion correction does a good job. The blurring at the edges of the picture is limited.

video mode

The Redmi Note 9 Pro is able to record videos in 4K with 30 pictures-per-second to record. On reduced 1080p Dissolutions are even fluid 60 pictures-per-second possible. The video encoder is between H.264 and H.265 selectable. A electronic image stabilization can be switched on at 4K and 1080p @ 30.

Given that it's a mid-range smartphone, the video quality is acceptable. The colors are displayed accurately and the image is extremely sharp. Noise does not appear. The recorded one Stereo sound is clear. In addition to the main camera, videos can also be recorded using the ultra wide-angle camera and the macro camera. The maximum resolution is reduced to 1080p @ 30.

Filters can be placed directly over the holder. However, the resolution is reduced to 720p. Special recording modes, such as a 960 FPS Slow motion mode or a Short video modeare available in the MIUI camera app. You create a particularly cool effect with the Kaleidoscope mode.

Practical test of the front camera

Our impression of 16 MP front camera with f / 2.48 aperture is rather mixed. Especially in high-contrast situations in which the dynamic range is exceeded, the details are visibly lost and colors sometimes appear washed out. The image noise increases visibly under poor lighting conditions. The front camera of the Redmi Note 9 Pro is still sufficient for one or the other selfie.

Functions such as an HDR mode, the camera AI or various filters are available. The front camera records videos with maximum 1080p @ 30 resolution.


The connectivity of the Redmi Note 9 Pro.


The Redmi Note 9 Pro is a Dual SIM smartphone, which can be operated with two nano SIM cards. Both SIM slots are able to connect to the 4G LTE cellular network. Volta, i.e. voice telephony via 4G and VoWiFI (WiFi calling), voice telephony via WLAN, are supported. Here is an overview of the Redmi Note 9 Pro Global tapes:

The smartphone shows strong reception in mobile communications. The voice quality is excellent in both directions. Speech is understandably received by the recipient. The noise-reducing microphone effectively filters out disturbing noises.

Wi-Fi and Bluetooth

For wireless connection establishment Dual AC WiFi and Bluetooth 5.0 supported. The data throughput in the WLAN is in no way inferior to that of more expensive smartphones. The Redmi Note 9 Pro convinces with good transmission and reception performance.

There was a catch at the time of this test. In standby mode, the smartphone loses the connection to the router. Routers from AVM (FritzBox) are particularly affected. The problem is known and Xiaomi has already announced a bug fix.

GPS and sensors

The Redmi Note 9 Pro takes up position determination GPS, A-GPS, Galileo, GLONASS and Beidou back. The location is determined quickly and with high accuracy. During a test drive through the city and over the country, there were no abnormalities. The navigation was consistently precise, as you can expect from a good smartphone.

NFC is available. Mobile payment, for example with Google Pay, works. The Fingerprint scanner is integrated directly into the side power button. The scanner is easily accessible and quickly unlocks the smartphone. The IR blaster enables the control of television sets. With the Mi Remote App, the right application is already pre-installed on the smartphone. The other sensors include a proximity sensor, an acceleration sensor, a brightness sensor, a gyroscope and an e-compass.


The Mono speaker the Redmi Note 9 Pro is no sound miracle to be expected. There are no basses and overall the sound is a bit flat. The differentiation is good and the maximum volume is pleasant.

On a 3.5 mm audio jack was not waived on this smartphone. Wireless Bluetooth headphones benefit from Qualcomms aptX Codec.


A highlight of the Redmi Note 9 Pro is clearly that 5020 mAh battery. It is hardly possible to bring him to his knees in just one day. We were able to achieve a consistent result in the benchmark Screen on time of 15 hours measure up.

The battery lasts on average for everyday use 2 daysbefore the smartphone has to be connected to the electricity. To get the large battery recharged as quickly as possible, the Redmi Note 9 Pro uses one 30 watt fast charging technology. It only takes a full charge 75 Minutes.

You really helped me with the test report. 🙂 I still have one question. Other test reports read more often that the back is made of plastic. You write that it is made of glass. What's the right answer? LG
