Xiaomi Redmi 9T review: Entry-level smartphone with huge battery, NFC, and stereo sound

Poco M3 alternative. Since the price of the Redmi 9T has already dropped considerably compared to its MSRP of 170 Euros (~$204), the smaller sibling of the Redmi Note 9T offers a lot of smartphone for users on a tight budget according to its spec sheet. Moreover, enormous runtimes are possible with the Redmi phone thanks to its huge battery...

Xiaomi Redmi 9T review

The diversity of models in the Redmi 9 series doesn't seem to have an end. Like its sibling models Redmi 9Redmi 9A, and Redmi 9AT, the newest member, the Redmi 9T, is a very affordable smartphone that offers very appealing technical specifications for this price range. For example, the Xiaomi phone has a 6,000 mAh battery, stereo speakers, NFC, a Full HD+ IPS display, and a 48 MP main camera. The following configurations of the Redmi 9T are available:

I. 64 GB storage / 4 GB RAM: 170 Euros (~$204) (MSRP)

II. 128 GB storage / 4 GB RAM: 200 Euros (~$240) (MSRP)

Unlike the Note 9T, the cheaper Redmi 9T doesn't support 5G; it can only access mobile Internet via the LTE standard instead. Due to the use of the Qualcomm Snapdragon 662, performance also falls significantly behind that of the Note 9T 5G.

Case - Redmi 9T with notch

Xiaomi Redmi 9T review

Prospective buyers of the Xiaomi phone can choose between Twilight Blue, Sunrise Orange, Ocean Green, and Carbon Gray. It's common for the design aspect to be debatable, but we are a bit conflicted about the look of our blue variant, which features a distinctive 9T series logo. On one hand, we like the grooved and consequently fingerprint-resistant texture of the plastic back, but on the other hand, the engraved lettering, which we're already familiar with from the realme 8 Pro, takes a bit of getting used to.

However, no "acclimatization" is necessary in terms of stability and workmanship, which are at a very decent level in the Xiaomi smartphone. The built-in volume control buttons also sit relatively firmly in the frame, and the same applies to the power button with the integrated fingerprint sensor, which is often a bit wobbly in smartphones. In addition, the Redmi 9T's case features a nano-coating that protects it from splashing water - but an official IP certification is not available.

The front of the Redmi 9T is made of a scratch-resistant third-generation Gorilla Glass display that is flush with the plastic frame. The 6.53-inch IPS display is surrounded by a moderate bezel on the sides. However, the tall bezel below the display only leads to an average screen-to-body ratio of about 83%.

Connectivity - Xiaomi smartphone with 3.5 mm audio jack

The Redmi 9T's feature list includes an FM radio, a triple card slot so that the dual-SIM function can be used independently of the dedicated SD card slot, a 3.5 mm audio jack, and an IR blaster as well as Miracast.

The internal UFS storage has a capacity of 128 GB in our review sample, where 21 GB is already occupied by the system out of the box. The 6,000 mAh battery is charged at up to 18 watts via the USB-C 2.0 port at the bottom of the case, and the Redmi smartphone can also be used as a power bank. USB OTG is also supported, so memory sticks can easily be connected to the Redmi 9T, for example.

Software - Xiaomi phone with MIUI 12

Google's Android version 10 is used as the operating system. At the time of testing, the manufacturer's in-house MIUI 12.0.07 user interface with security patches from March 2021 is installed on top.

The MIUI 12 user interface offers a lot of customization options and a well-optimized system interface. With the separate notification center, the app switcher, and the design of the control center, it's very reminiscent of Apple's iOS, but that isn't a negative thing.

However, what slightly degrades the MIUI 12 interface in budget Redmi models are the short advertisements that appear as soon as an app is installed - nevertheless, we didn't discover more of these banner ads. The large number of third-party apps is also noticeable, but these can be completely uninstalled.

Communication and GNSS - Redmi phone with NFC

Unlike the Redmi Note 9T, the "normal" 9T can only access LTE networks; a 5G modem for fast on-the-go Internet is not on board. The price range of the Xiaomi smartphone is also reflected in the number of supported LTE frequencies - access to a total of 12 LTE bands is supported. Nevertheless, all relevant frequencies are covered for the German-speaking regions.

The Redmi phone's WLAN module supports the IEEE 802.11a/b/g/n/ac standard, so the 9T model can be used within the 2.4 GHz and 5.0 GHz frequency bands, and the transfer rates in our Wi-Fi test are correspondingly solid. In combination with our Netgear Nighthawk AX12 reference router, we determine transfer rates of about 300 Mb/s, which is fine for a smartphone in this price range.

Besides "real" dual SIM, the Chinese manufacturer supports Bluetooth 5.0 in terms of communication modules. An NFC chip for near-field communication and contactless payments is also on board.

The device's position is determined by means of the following main satellite systems: GPS, GLONASS, Galileo, and BeiDou. The satellite fix is obtained quickly outdoors and with an accuracy of about 4 meters. Even indoors, the Redmi 9T is able to determine its position quite fast.

In order to be able to assess the positioning accuracy of our test device in practice, we track a route with the Garmin Edge 520 GPS bike computer in parallel for comparison purposes. At 40 meters, the deviations are low, and the GPS log's detailed trajectory is also convincing with its accurate positioning; consequently, nothing stands in the way of using the Redmi 9T for navigation purposes.

Telephone and call quality - Redmi 9T with Wi-Fi calling

Xiaomi Redmi 9T review

The Redmi 9T offers decent call quality. The two built-in microphones provide satisfactory intelligibility in the test. Video calls using the built-in front-facing camera also work smoothly.

The Xiaomi phone supports dual SIM with two physical SIM cards. Phone calls via Wi-Fi are supported, but we couldn't find an option for VoLTE in the settings menus.

Cameras - Xiaomi phone with quad-camera setup

Portrait photo taken with the Redmi 9T

At the front, an 8 MP camera is integrated into the display's notch; it produces somewhat soft-looking selfies with little dynamic range, but the results are absolutely acceptable for Instagram and the like.

Despite the low price, the Redmi 9T has four camera lenses at the back. The quad-camera module consists of a 48 MP main camera with an maximum aperture of f/1.79. The Xiaomi smartphone label hasn't revealed the exact model of the image sensor, but it's allegedly the Samsung GM1, which is also supposed to be installed in the Poco M3. The sensor supports pixel-binning, so that every 2x2 adjacent pixels can be merged into one large pixel.

The quad-pixel technology of the main camera provides 12 MP photos by default, but the photo results are only convincing to a limited extent. The pictures have little dynamic range; they're also relatively dark and blurry. Up to an 8x digital magnification is possible. With increasing darkness, photos tend to suffer more from image noise and strong blurriness.

In addition to the 48 MP main camera and the two 2 MP sensors for macro and bokeh effects, the Redmi 9T has an 8 MP ultra wide-angle camera. Usable results can be achieved with the ultra wide-angle lens when there's a lot of light, but some compromises have to be made in terms of image sharpness and details compared to the main camera. As with other low-priced phones, this is a nice addition, but the ultra wide-angle lens is only suitable for the odd snapshot in terms of quality.

Videos can only be recorded in Full HD and at 30 fps with all cameras, similar to the Redmi 9. A stepless transition when using the ultra wide-angle and standard lenses to zoom is not possible.

We subject the rear-facing 48 MP camera to further tests under controlled lighting conditions. We use the ColorChecker Passport tool to analyze the camera's color reproduction in comparison to the actual reference colors. We take measurements once in full studio lighting and once at 1 lux of light intensity.

Colors are reproduced surprisingly well with the Redmi 9T. White balance could be better, and black and gray tones are not quite right, but no real weaknesses are apparent. Compared with the reference colors, the smartphone shows colors in a brighter way as is typical for smartphones, but the Delta E deviations are low for this price range.

The image sharpness in our test chart isn't very pronounced at the edges, but structures and transitions are easily recognizable at the center of the image.

Accessories and warranty - Redmi 9T with case included

The power adapter of the Redmi 9T
The power adapter of the Redmi 9T

The box contains a modular power adapter with a rated output of 22.5 watts, a USB charging cable, and a silicon case. There's also a factory-preinstalled protective film.

Xiaomi offers a 12-month warranty period with its smartphone.

Input devices and handling - Xiaomi phone with fingerprint scanner

The 6.53-inch LC display accurately responds to inputs all the way to the touchscreen's corners. However, the affordable Redmi phone doesn't offer a refresh rate beyond 60 Hz like the Moto G30.

An active fingerprint sensor is integrated into the power button. The biometric fingerprint recognition is reliable, but the sensor's speed leaves much room for improvement. It takes a good second to think before the screen is woken up from standby mode.

Another way to unlock the device is 2D face recognition using the front-facing camera. The recognition rates are convincing, but this type of unlocking is quite unsafe.

Display - Redmi phone with IPS panel

Subpixel grid
Subpixel grid

The 6.53-inch 60 Hz LC display has an aspect ratio of 19.5:9 with 2340x1080 pixels and a pixel density of just under 400 PPI. Xiaomi uses pulse width modulation to control the display brightness at levels below 25%.

For an entry-level phone, the maximum brightness with a completely white screen background is a satisfactory 467 cd/m², which isn't very much in absolute terms, but it's above the manufacturer's specifications (400 nits). The Redmi Note 9T counterpart has a higher brightness than the 9T, and it's also much more homogeneous.

In addition, we test the display's brightness with an evenly distributed ratio of dark to bright areas (APL50). We determined a maximum brightness of 486 cd/m² here.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 880.3 Hz ≤ 25 % brightness setting

The display backlight flickers at 880.3 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 25 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 880.3 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9679 (minimum: 5 - maximum: 151500) Hz was measured.

Considering that this is a low-priced smartphone, the analysis performed with the spectrophotometer and the CalMAN software reveals very low average Delta E deviations from the sRGB color space of 1.35 (colors) and 1.4 (grayscales), respectively. The color temperature is very well tuned at around 6,400 K.

In comparison with the IPS competition, the LC display of the Redmi 9T has a very satisfactory black level of 0.25 cd/m². Thanks to the solid brightness, the IPS panel is also able to achieve a good contrast ratio.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

The Xiaomi phone's liquid crystal display performs solidly outdoors, and content is usually reasonably legible in sunlight. However, reflections on the display result in problems when viewing the screen outdoors.

Viewing-angle stability is at a good level, even if the panel dims in a visible way. Even at very flat viewing angles, however, display content is reproduced with relative color accuracy.

Performance - Xiaomi phone with Snapdragon SoC

The Redmi 9T has problems with benchmark apps
The Redmi 9T has problems with benchmark apps

The Qualcomm Snapdragon 662 is manufactured in an 11 nm process, and it has a Kryo 260 CPU unit. Four Cortex-A73 cores run at up to 2 GHz, and the remaining Cortex-A53 cores run at a clock rate of 1.8 GHz. The Qualcomm Adreno 610 is used as the graphics unit.

The system often runs smoothly with our 4 GB version, but we constantly had to cope with brief stutters. Scrolling is a bit choppy in complex websites in particular. Application loading times are neither especially fast nor especially slow due to the UFS 2.2 storage. It should be noted that the 64 GB version comes with UFS 2.1 storage and should consequently be a bit slower.

We normally get a more accurate impression of the SoC by means of a comprehensive benchmark package. However, tests like GFXBench or 3DMark cause problems under the Redmi 9T's current MIUI 12 software. Some Xiaomi models apparently have a firmware lock that prevents benchmarks from establishing network connections. In our case, the Redmi 9T is connected to the Internet, but the firmware lock prevents the benchmark from connecting to the servers to download benchmark files and device list updates. The Redmi phone's performance in benchmarks should be roughly on par with that of the Poco M3.

Games - Gaming with the Redmi 9T

We look at the gaming performance with the app from our partner GameBench. Playing PUBG Mobile on the Redmi 9T is only possible at very low graphics settings, and we weren't able to get frame rates above 30 fps out of the Redmi phone either. Even the Armajet shooter, which theoretically supports frame rates of 144 Hz, is only playable at an average of 38 fps, but strong drops (<20 fps) have to be tolerated here as well.

The games that we tested run without issues on the Redmi 9T, and there's nothing to complain about in terms of controls and sound either.

The Redmi 9T heats up to almost 43 °C (~109 °F) under continuous load. In everyday use, the Xiaomi phone's heat development isn't a problem because the case usually only gets lukewarm. Normally, we also analyze the temperature behavior of the Snapdragon SoC during continuous load with the battery test of the GFXBench app. Unfortunately, the app doesn't work under the Redmi 9T's firmware (at the time of testing).

Speakers

Speaker test: Pink Noise
Speaker test: Pink Noise

The Redmi 9T makes use of two speakers that produce stereo sound when playing music or videos. Together, the two sound sources offer an appealing quality for this price range and reach a maximum volume of a good 84 dB(A). Our measurements show a relatively linear frequency response for mids, and highs are well represented too.

If you want to add some bass to the sound pattern, you can resort to wired or wireless headphone solutions. Besides the classic 3.5 mm audio jack, the Bluetooth 5.0 standard is available as well. Besides SBC and AAC, aptX, aptX HD, LHDC, and LDAC are among the supported codecs.

Battery life - Xiaomi smartphone with huge battery

Energy consumption

The Redmi 9T's power supply is provided by a 6,000 mAh battery that is charged at 18 watts with the included Quick Charge power adapter. As a result, the Xiaomi smartphone is fully recharged within 2.5 hours. Furthermore, the Chinese manufacturer has stated that the 9T's battery is supposed to offer a particularly high number of charging cycles (>1,000).

Power consumption is a bit high compared with the Poco M3's rates; the system doesn't seem to have been optimized yet in this regard.

Battery life

One of the major strengths of the low-priced Redmi phone is its battery life. The 9T delivers excellent runtimes when browsing in our Wi-Fi test, and the same applies to the rates in our continuous video playback test, which was also performed with an adjusted display brightness of 150 cd/m². Even heavy users should easily get through the day with one battery charge under intensive use; this could even be two days. Due to the relatively high power consumption under load, the Redmi 9T runs out of power after just over 5 hours in the battery stress test.

Verdict on the Redmi 9T - A small amount of compromises for little money

In review: Redmi 9T. Test device provided by nbb.com
In review: Redmi 9T. Test device provided by nbb.com

With the Redmi 9T, the Chinese manufacturer has managed to create a really good entry-level smartphone with a well-rounded overall package for little money, just like with the Poco M3. Thanks to NFC support and the ultra wide-angle camera, its features are even a bit better than those of its sibling model under a different brand.

Considering the price range of the Redmi 9T, there are hardly any real sacrifices to be made - at the time of testing, prices start at around $190.

Users who have already had the chance to experience panels running at over 60 Hz will surely find the Xiaomi phone to be a bit less smooth. In addition, the aging Kryo 260 cores of the built-in Snapdragon 662 don't turn the Redmi 9T into a performance monster below the $200 mark - rather the opposite is true.

Among the plethora of Redmi 9 and Redmi Note 9 models, the Redmi 9T hardly offers any added value, but it's still a good choice for budget-conscious buyers.

The very long battery life combined with the very decent, relatively high-resolution panel and the stereo speakers results in a strong overall package compared with the competition.

Price and availability

The Redmi 9T (64 GB / 4 GB) can be found on newegg for just under $175, while the maxed-out version with 128 GB of storage costs $193 on newegg and $196 in Walmart's online store.

If you're in the UK, you can find it on Amazon at prices starting at just under £185 (~$257) or at around £198 (~$275) for the 128 GB version.

I have always been very passionately interested in mobile technologies, especially smartphones. Being a tech enthusiast means the half-life of my devices isn’t exactly long, and being the latest hardware is not enough to suffice as the manufacturer and operating system play a minor role – the most important aspect for me is that the device is state-of-the-art. After posting for Mobi Test I joined Notebookcheck in 2016, where I have been pursuing my enthusiasm for technology by reviewing the latest smartphone, tablet, and accessory trends.

I've been fascinated with technology ever since I got my very first Android smartphone, which was quite a while ago. The power packed into such a small footprint still amazes me. Learning to program made my understanding of technology deeper, and at the same time, it expanded my interest to the area of desktop computers and laptops. All this led me to enjoy reading and watching reviews of new devices, and that's how I stumbled upon Notebookcheck. I immediately found their reviews to be very comprehensive, and luckily, I've even had the chance of translating them since 2019. When it comes to the huge field of technology, I'm currently also interested in specializing in Java programming.
