BatteryThe Mi 11 Ultra is Xiaomi’s 2021 flagship packed with an array of high-end hardware. Powered by the top-end Snapdragon 888 chipset, the device comes loaded with 12 GB RAM and 256 GB of storage, as well as a 5000 mAh battery with fast 67W wired and wireless charging. The display is a 6.81-inch WQHD+ AMOLED with a 120 Hz refresh rate, DCI-PS color gamut, and HDR10+.
It’s not lacking in the photography department either, and its triple rear camera has only recently been toppled from the top of the DXOMARK Camera rankings. You can use the rear camera to capture selfie images using a tiny 1.1-inch AMOLED screen (126 x 294) that is installed next to the camera array. It serves as a preview screen for taking selfies with the primary or ultra-wide camera, and doubles as a notification screen or always-on display.
Today we’re interested in its selfie-cam potential, however, and the Xiaomi Mi 11 Ultra’s front-facing module offers a 20 MP-resolution sensor coupled to a fixed-focus f/2.3 aperture lens. Front-facing video is captured in full HD 1080p resolution at either 60 or 30 fps, and there’s a slow motion 720p/120 fps mode if you want to get creative.
So will the Xiaomi Mi 11 Ultra’s selfie shooter live up to the high standards set by the rear camera? Let’s find out as we unveil the scores and compare some pictures.
Key front camera specifications:
- 20 MP 1/3.4″ sensor
- f/2.3 aperture lens
- Video: 1080p/60&30fps, (1080p/30 fps tested) and 720p mode

With an overall Selfie score of 94, the Xiaomi Mi 11 Ultra improves on the score of 88 set by its predecessor, the Mi 10 Ultra. That’s primarily due to improved front camera photos, where the latest model puts in a slightly better performance across almost all test categories. There’s less of an improvement for video, however, and with the Mi 11 Ultra at 92 and the Mi 10 Ultra at 91, the two models essentially offer generally comparable front camera video image quality.
With a price tag of around $1200, the Mi 11 Ultra is squarely in our Ultra Premium segment of more expensive devices. Compared to the best-performing Ultra Premium selfie cameras, Xiaomi’s 2021 flagship unfortunately doesn’t fare quite as well, only just squeaking into the top 20 and quite a ways behind the leading Huawei P50 Pro at 106 points.
Its strengths include accurate and stable selfie photo exposure, as well as pleasant skin tone rendering and accurate white balance in most photos. Depth of field is also wide and detail on faces positioned a little distance from the camera is good. The fixed-focus lens missed focus on close-range selfies, however; fine textures are lost and some luminance noise is visible in all photos; and contrast on faces can be disappointing in certain conditions.
Shooting video, strengths are broadly the same, with generally accurate face exposure, wide depth of field and pleasant color. The devices handles noise a little better in videos, too, with smooth files captured in all but the most challenging conditions. Video dynamic range is limited, so expect some highlight clipping when recording in bright light; and the level of video detail is generally low, especially in low light. Video stabilization is generally effective, but we did notice slight residual motion effects and differences in sharpness between frames in some conditions.
Below you can find a detailed analysis and image samples for all Photo and Video sub-attributes, as well as comparisons with one of the Xiaomi Mi 11 Ultra’s brand-mates, the standard Mi 11 variant, and with one of the Mi 11 Ultra’s competitors, the Samsung’s Galaxy S21 Ultra 5G (Snapdragon).

These samples show the Xiaomi Mi 11 Ultra’s noise performance in an indoor scene. Luminance noise is visible in all conditions and especially in low light.
For these tests we switch to the camera’s bokeh or portrait mode and analyze depth estimation, bokeh shape, blur gradient, and repeatability, as well as all other general image quality attributes mentioned previously. The score is derived from perceptual analysis of real-life images.
These samples show the Xiaomi Mi 11 Ultra’s bokeh mode performance in an indoor scene. Similar to the Xiaomi Mi 11, the Ultra model captures bokeh with a pleasant shape, but some depth artifact errors are visible and no blur gradient effect is applied.
In these tests we check images for optical artifacts such as vignetting, flare, lens softness in the corners, distortion, and chromatic aberrations, as well as for processing artifacts such as ghosting and fusion errors, hue shift, and ringing.
This sample shows flare artifacts in a backlit image. Other artifacts including color quantization and hue shift effects are also occasionally visible on the Xiaomi Mi 11 Ultra.
Video
In our Video tests we analyze the same image quality attributes as for still images, such as exposure, color, texture, and noise, but we also include such temporal aspects as speed, smoothness and stability of exposure, white balance, and autofocus transitions.
The Xiaomi Mi 11 Ultra achieves a Selfie Video score of 92. A device’s overall Video score is derived from its performance and results across a range of attributes in the same way as the Photo score. In this section, we take a closer look at these sub-scores and compare video image quality against other devices.
