Xiaomi 12T

Rating: 5

I received a Xiaomi 12T.

Just the right high performance with 8100-Ultra

Xiaomi 12T is a smartphone powered by MediaTek Dimensity 8100-Ultra.

The Dimensity 8100-Ultra uses the TSMC 5nm process and combines GPU performance on par with the Snapdragon 888 and power-saving performance on par with 8+ Gen 1.

Despite being a mid-to-high-end model, it has many useful features for everyday use, including a 108MP camera, 120W fast charging, and a 1.5K resolution display with 120Hz refresh rate support.

This review is based on version, 8GB+256GB version.

  • 1.5K display
  • AMOLED with 120Hz refresh rate support
  • Relatively low power consumption MediaTek Dimensity 8100-Ultra
  • 5000mAh battery with 120W fast charging
  • Built-in stereo speakers
  • Weaker for night shots
  • Weaker heat generation measures than 12S Ultra

Xiaomi 12T

Accessories include a protective case, 120W charger, USB Type-A to C cable, and instruction manual.

Protective film is attached from the beginning.


Xiaomi’s first smartphone with a 1.5K display

Most previous Xiaomi smartphones have been FHD or 2K resolution, but the Xiaomi 12T is in between, with 1.5K resolution.

It offers higher resolution than FHD and lower power consumption than 2K.

The flat display allows easy viewing to the edges of the screen, and the central punch hole is small and unobtrusive.


The panel is diamond pixel array.


The maximum reached 875 nits during HDR video playback with automatic brightness adjustment on.


The touch latency measured by the WALT Latency Timer was 8.3ms from touch to kernel, 3.7ms from kernel to Java, and 28.0ms for screen rendering, for a total of 40ms.

Although devices with MediaTek SoC often have large latency in screen rendering, the latency was kept at a level comparable to that of the Xiaomi 12S Ultra.


Widevine L1 allows streaming in HD quality on Amazon Prime Video (beta) and others.


Equipped with an in-screen fingerprint sensor

The Xiaomi 12T has an in-screen fingerprint sensor for quick authentication there.

It can also be used with face unlock.

Fingerprint-resistant back

The back of the Xiaomi 12T is smooth and fingerprint resistant.


The weight is 205.6g including the factory attached protective film.


108MP triple camera

The Xiaomi 12T has a triple camera configuration with a 108MP Samsung S5KHM6 as the main camera.


The photos taken are stored here.


Saturation is not extremely emphasized, and red and magenta are easily distinguished.


I tried shooting at 1x, 0.6x, and 2x in that order.

At 0.6x, the details are crushed because of the use of an 8MP ultra-wide angle camera.




Flare and ghosting are likely to occur when the lens is aimed at a strong light source.


Stereo speakers with Dolby Atmos

The Xiaomi 12T has Dolby Atmos-compatible stereo speakers.


The audio output delay was 126.6 ms when measured with the WALT Latency Timer.


5000mAh battery that can be fully charged in 25 minutes

The Xiaomi 12T has a 5000mAh battery and supports 120W fast charging.

It is a good combination of high capacity and fast charging.

USB Type-C

The battery is charged at a maximum of about 98W when boosted, and once above 50% it is held in the 30W range and then gradually rises to the 40W range.




Buttons are concentrated on the right side

There is nothing on the left side of the Xiaomi 12T.


The power and volume buttons are all on the right side.

The frame is plastic and does not conduct heat very well even when heated.


CPU performance is low, but GPU is on par with 888

The MediaTek Dimensity 8100-Ultra has a slightly lower CPU performance than the Snapdragon 870, but the GPU performance is about the same as the Snapdragon 888.

Since the GPU is often used for heavy processing in apps, it makes sense to have sufficient CPU performance while supporting it with a strong GPU.


In Geekbench 5, the Genshin disguised version has 753 single-core and 2990 multi-core, while the normal version has 922 single-core and 3007 multi-core.

We are throttling by package name, which seems to have a significant impact on the single cores.


In PCMark Work 3.0, which measures performance in everyday use such as document manipulation, the score was 13624.

This score is close to that of a Snapdragon 8 Gen 1 / 8+ Gen 1 equipped smartphone.


In the 3DMark Wild Life Stress Test, the score was 5900, with a temperature rise from 30°C to 47°C (17°C increase), 25-43 FPS and 10% battery consumption.

Stability is quite stable at 99.6%, and the temperature rise is slow and excellent.


Storage is UFS 3.1, with particularly fast sequential read/write.


Since GAME TURBO allows performance settings, game performance is measured in performance mode.

Playing Genshin at the highest quality and 60 FPS setting and measuring with WeTest PerfDog, the average power consumption was 100.76 mW per FPS at 57.7 FPS.

Battery temperatures rose to a maximum of about 45°C, but the side frames did not get as hot.

There were occasions where the FPS dropped to 30FPS after 15 minutes, possibly due to throttling caused by the temperature rise.

The frame rate and power savings are similar to the Snapdragon 8+ Gen 1, but the heat generation measures seem to be a bit lacking.


In World of Tanks Blitz, playing at 120FPS settings and all graphics settings at their highest values, the average was 111.1 FPS, with a power consumption of 41.45 mW per FPS.

With the realme GT Neo 3 150W with Dimensity 8100, the frame rate was easy to drop, but with the Xiaomi 12T with 8100-Ultra, the level is comparable to Snapdragon smartphones.

The temperature rose to 37.9°C.



  • 1.5K display
  • AMOLED with 120Hz refresh rate support
  • Relatively low power consumption MediaTek Dimensity 8100-Ultra
  • 5000mAh battery with 120W fast charging
  • Built-in stereo speakers
  • Weaker for night shots
  • Weaker heat generation measures than 12S Ultra


The Xiaomi 12T has a high performance but low power consumption thanks to the MediaTek Dimensity 8100-Ultra with TSMC 5nm process and a good battery life.

Even when the battery runs out, it can finish charging in less than 30 minutes thanks to 120W fast charging.

It is an excellent middle-high smartphone with the only major negative point being the camera’s slightly poor night shot performance.
