Verdict
The Xiaomi 15T has become a real price-performance hit in a very short time. The high RRP of almost 650 euros is forgotten at the current price level of around 400 euros, just a few weeks after the market launch. For an affordable mid-range smartphone, the Chinese manufacturer's new T model actually has everything it takes to become a bestseller.
The 6.83-inch 120 Hz OLED panel is not only super bright, but also offers a high pixel density and eye-friendly high-frequency PWM dimming. In combination with the overall appealing Dimensity 8400, users can also enjoy the Xiaomi 15T for a long time, thanks to its attractive battery life. The same applies to the Leica main camera, which produces very respectable photos in the mid-range.
Even though the 15T will probably only be updated to Android 19, the Xiaomi phone scores with a fairly long update period. If you also use a case for your smartphone, you may forgive the plastic casing for its lack of value. The Xiaomi 15T also lacks other premium smartphone features, such as wireless charging or a fast USB port.

Cons
Price and availability of the Xiaomi 15T
Although the Xiaomi 15T has a base RRP of 649.90 euros (approximately US$750), the price drop shortly after its launch is very pronounced. The mid-range smartphone is already available for around 400 euros from online retailers, including Amazon.de or directly from the manufacturer.

Just in time for the Christmas season, Xiaomi is once again launching its updated T series on the market, which traditionally aims to score with a strong price-performance ratio. The new Xiaomi 15T is no exception.
Equipped with new Leica cameras and a more powerful MediaTek SoC compared to the 14T, the mid-range phone is vying for the favor of price-conscious buyers. Those who highly value zoom photos can also check our Xiaomi 15T Pro review for more information.
Specifications of the Xiaomi 15T
Case - Waterproof Android-Phone
Xiaomi has adopted the design language of the previous models for the 15T. The gold color of our test sample is a new addition. The display has grown to 6.83 inches, and at 194 grams, the Xiaomi 15T is slightly lighter than the 14T model.
The mid-range smartphone is IP68-certified and offers a modern look with a high screen-to-body ratio of over 90 percent. Gorilla Glass 7i protects the OLED display against scratches.
The back is made of glass fiber-reinforced plastic, while the frame is also made of plastic and not aluminum like its predecessor. Despite minor compromises in the feel, the Xiaomi 15T impresses with its good workmanship.
Features - Only USB 2.0 for the mid-range phone
Xiaomi still relies on a USB 2.0 port for its T model without the option of image output. In our copy test, we achieved a transfer speed of just 30 MB/s with a Samsung Portable SSD T7. The connected storage media can be formatted with either NTFS or exFAT. However, USB-OTG is supported, allowing external devices to be connected without any problems.
Xiaomi uses LPDDR5X for the main memory. However, the internal storage uses a fast UFS 4.1 memory.
In terms of connectivity, the Xiaomi 15T already offers Bluetooth 6.0 for improved connectivity and energy efficiency compared to older Bluetooth versions. An IR blaster and NFC are also on board, enabling contactless payment and control of televisions or air conditioning systems. Miracast is available for wireless image transmission.
Ultra-wideband (UWB), a technology for precise positioning of smart tags, for example, is not included.
Software - Xiaomi smartphone with Android 15
The T series is advertised with four Android updates and six years of security updates. Since Xiaomi relies on Android 15 ex-works, Android 19 should be the end of the road. At around 400 euros, this is certainly not a deal-breaker, but Samsung or Google offers a little more future-proofing here.
The Xiaomi 15T was still running HyperOS 2.0 as the operating system during the test, but the global rollout of the major software update to HyperOS 3 has already begun. With an update during the test, the security patches are up to date as of October 2025.
Sustainability
The Xiaomi 15T is listed in the EPREL database with repair class C. This means that the availability of spare parts (in theory) is regulated for at least 6 years. Xiaomi does not provide information on the use of recycled materials for specific models, but only in very general terms, and CO2 emissions are not disclosed.
Communication and GNSS - Calls not via satellite, but without mobile communications
Unfortunately, the Xiaomi 15T does not come with modern WiFi 7, but only WiFi 6E. Nevertheless, the speed in the practical test is very high thanks to the use of the 6 GHz band. In combination with an Asus ROG Rapture GT-AXE11000, we achieved an average of over 1,600 MBit/s, which is slightly slower than the predecessor.
It also supports all current mobile communication standards, including 5G Sub6 and a wide range of LTE frequency bands. This means that the mid-range phone should be able to establish a data connection anywhere.
The Xiaomi 15T does not offer classic satellite communication, but the company's own Astral Communication can be used. This enables a direct connection between two Xiaomi devices without an active Wi-Fi or mobile phone connection. The manufacturer specifies a range of up to 1.3 kilometers for phone calls. However, this function is currently only available for the T series.

The Xiaomi phone quickly performs a Satfix outdoors with a high accuracy of 1 meter. In our practical test, we compare the Xiaomi 15T with a Garmin smartwatch (Venu 2). Both have some inaccuracies, but the mid-range phone's positioning is more than sufficient for navigation tasks.
Phone functions and voice quality - Xiaomi smartphone supports two eSIMs
For the price range in which the Xiaomi 15T operates, it offers very interesting options. In addition to 5G+5G dual SIM with two nanoSIM cards, users can also integrate two eSIMs into the system. A combination of both worlds is also possible.
The voice quality is natural and the noise suppression works satisfactorily. In addition to VoNR and VoLTE, VoWiFi is also supported.
Camera - Android-phone with Leica cameras
Although Xiaomi is positioning its T-series as a photo pro with its Leica camera, the hardware is not quite on par with the flagship competition, in many respects.
Compared to the camera elite, the main camera of the Xiaomi 15T uses a somewhat small 1/1.55-inch sensor, which is also used in the Mix Flip 2. Nevertheless, good photos in daylight are possible with the Light Fusion 800. The images show an appealing sharpness and high dynamic range. However, details are not brought out perfectly with the mid-range smartphone, and the contrast also drops slightly. In low light, the low yield and soft focus are not surprising due to the lack of a sensor.
With only 2x optical zoom, the telephoto camera is useful up to 5x magnification, but beyond that, it quickly becomes pixelated and artificial. We also feel that the exposure is not optimal. The same applies to the telephoto lens: it lacks OIS, as does the main camera, but at least it has autofocus.
The ultra-wide-angle lens has neither optical image stabilization nor autofocus. The imaging performance is decent, but it shows edge artifacts and blurring.
The mid-range smartphone records videos in Ultra HD with up to 60 FPS at best.

The Xiaomi 15T reveals a very decent color reproduction under controlled lighting conditions. In our measurement, the colors are slightly brighter than the reference, but the DeltaE deviations are still significantly lower than those of the Flagship models (we tested the China version).
Accessories and warranty - Xiaomi phone comes without power adapter
The mid-range phone comes with a USB-C cable, a TPU case, and a SIM tool. A protective film is also pre-installed ex-works. The matching fast-charging power adapter or other accessories are optionally available in the manufacturer's online store.
The Warranty for the Xiaomi 15T is only 12 months in Germany and can be extended with the in-house Care insurance package against accidental damage and theft. Depending on the insurance scope, this costs between 74 and 104 euros at the time of testing.
Input devices and operation - Xiaomi 15T with Face Unlock
The Xiaomi 15T has a touchscreen from Tianma with a sampling rate of up to 2,560 Hz. However, this high refresh rate is only active in Game Turbo mode. The company's own wet-touch technology is also on board, enabling sensible operation with wet hands, and it worked well in the test.
An in-display sensor is available for biometric unlocking. The optical fingerprint recognition works reliably and quickly in the test, but not at the level of a Xiaomi 17. There is also an insecure 2D face recognition using the front camera.
The X-axis vibration motor of the Xiaomi 15T generates haptically appealing vibrations and conveys a feeling of value.
Display - Large OLED screen with DC dimming
Xiaomi uses an AMOLED panel with a 1,280p resolution and 12-bit color depth for its mid-range phone. With a diagonal of 6.83 inches, the pixel density is therefore a very good 447 ppi. The display can also automatically adjust the maximum frame rate of 120 Hz to 60 Hz or 90 Hz.
According to the data sheet, a peak brightness of 3,200 nits can be achieved. For our everyday usage scenario (APL18 sample), we are pleased to even exceed the manufacturer's specifications with 3,310 cd/m². With HDR content, we achieve a brightness of 3,267 cd/m². The Xiaomi 15T is therefore ideally suited for video content with a high dynamic range: HDR10, HDR 10+, Dolby Vision and HLG are available.
As is usual for smartphones with OLED screens, Xiaomi uses PWM to control the brightness. According to the manufacturer, the standard dimming method of the Xiaomi 15T for high brightness ranges is DC dimming, while high-frequency PWM dimming (3,840 Hz) is used for low brightness. We can also confirm the latter based on our measurement.

The display backlight flickers at 120 Hz (worst case, e.g., utilizing PWM) . The frequency of 120 Hz is very low, so the flickering may cause eyestrain and headaches after extended use. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8152 (minimum: 5 - maximum: 343500) Hz was measured. | |||

With HyperOS in the second generation, the Xiaomi 15T has various color profiles, a white balance and an adjustment of individual parameters, such as gamma values, to choose from. With a look at our tests of the Xiaomi 17 and 17 Pro the setting options should be somewhat reduced after the update to HyperOS 3.
We examine the color calibration with the Calman analysis software and a photo spectrometer. In the "Pro" profile, we found the smallest deviations from the reference colors and a high color fidelity. However, the Predecessor was slightly better calibrated in our measurement.

There are no problems with the mid-range phone's readability outdoors and content is also recognizable in direct sunlight. The viewing angle stability is also very good and there are no color distortions.
Performance - Android-phone relies on Mediatek
When it comes to the SoC, Xiaomi does not reach for the highest performance shelf for its 15T model, the Dimensity 8400 is still a decent chipset for the mid-range. A Poco F7 Pro with the Snapdragon 8 Gen 3 is a good deal faster than the Xiaomi 15T with its Cortex-A725 cores, especially when it comes to single-core performance. However, the Xiaomi phone makes a convincing performance in AI calculations.

For graphics calculations, a Mali-G720 MP7 is installed. The Xiaomi phone is therefore very well positioned for the mid-range. The GPU is sufficiently fast, even for demanding games - the Xiaomi 15T achieved 25 fps in the 4K test of the GFXBench. A big leap in performance compared to the Predecessor in the tier tests.

Games - Xiaomi 15T also interesting for gamers
The Xiaomi 15T is not a gaming smartphone, but its large, high-resolution screen and stereo sound still offer a really good gaming experience. The Mali-G720 MP7, which, unlike the Immortalis-G720, probably has to do without ray tracing, only managed 60 fps in our test. We determine the exact frame rates with the GameBench software.
Xiaomi itself lists several titles for the 15T model where 120 fps should be possible, including Call of Duty and Mobile Legends. The stable display for Genshin Impact confirms that the Xiaomi phone has sufficient GPU power for current games.

Speaker
The stereo speakers with Dolby Audio support sound good, but have very little depth. The Pink Noise also shows only a linear progression in the treble. Headphones or external speakers can be connected via the USB-C port. If you prefer to use Bluetooth for wireless output, there are many audio codecs and the new 6.0 standard, including Auracast.
