Xiaomi 11 ultra

The Best Android 

phone of 2021 

The best smartphone of 2021? With the Mi 11 Ultra, Xiaomi tried to create the best flagship smartphone in the Android space. The Mi 11 Ultra comes with a “massive” camera system. However, in one particular area, it is no better than an entry-level Android smartphone. Read our review to learn whether the Xiaomi smartphone is worth buying despite this shortcoming.The Xiaomi Mi 11 Ultra, which turned out to be a huge hit in China, packs the best hardware that is currently available in the smartphone market. Thanks to the largest camera sensor to ever be featured in a smartphone, the Mi 11 Ultra’s camera gets the highest DXOMARK score at this point in time

The rest of the specifications sheet also looks very impressive. This is why the Mi 11 Ultra costs about as much as the Galaxy S21 Ultra—at least in Europe. In Germany, the version with 12 GB of RAM and 256 GB of UFS 3.1 memory has an MSRP of 1200 Euros  The Mi 11, which launched in December, cost 400 Euros less. Buyers can save a lot of money by importing the Mi 11 Ultra from China. For instance, TradingShenzhen sells the Chinese version of the Mi 11 Ultra for just 830 Euros. TradingShenzhen lent us the Chinese version of the Xiaomi Mi 11 Ultra for this review

Display

The Xiaomi Mi 11 Ultra features a 6.81-inch OLED panel from Samsung. The display has a native resolution of 3200x1440 pixels and supports adaptive refresh rate technology. The refresh rate can fluctuate between 30 and 120 Hz, depending on the screen content. Here, the Samsung Galaxy S21 Ultra has a clear edge because it can reduce its refresh rate to 10 Hz and therefore save more energy.

The 10-bit panel of the Mi 11 Ultra has a very high brightness of 891 cd/m². The brightness is distributed very evenly across the screen. In our APL50 test, in which the screen displays a pattern that consists of evenly distributed dark and bright areas, the Xiaomi smartphone achieved 1252 cd/m², which is a very impressive result. Xiaomi claims that the Mi 11 Ultra can achieve a brightness of 1700 cd/m². We were unable to confirm this claim in our testing. However, the Mi 11 Ultra will probably be able to achieve a higher brightness in a 10% stimulus window (APL10). In any case, the Mi 11 Ultra offers enough brightness for HDR content.

Softwere 12.5

The Mi 11 Ultra runs Android 11 (security patch level at the time of our review: April, 2021). The Xiaomi smartphone comes with a custom launcher known as MiUI (current version at the time of our review: 12.5).

Xiaomi’s custom launcher looks very nice and offers a lot of customisation options. In terms of design, Xiaomi’s Android skin bears a lot of resemblance to Apple’s iOS.

Spapdragone 888 - perfomens

Xiaomi’s flagship smartphone is powered by the Qualcomm Snapdragon 888. The SoC features one Prime Core with a maximum frequency of 2.84 GHz, three Cortex-A78 high-performance cores with a maximum frequency of 2.42 GHz, and four Cortex-A55 cores with a maximum clock speed of 1.8 GHz. The Qualcomm Adreno 660 serves as the GPU.

In our suite of benchmarks, the Snapdragon 888 in the Mi 11 Ultra is able to achieve impressive results. Nevertheless, the Mi 11 Ultra is not able to beat the Asus ROG Phone 5. The Xiaomi smartphone does not perform very well in the PCMark benchmark. Under sustained load, the Mi 11 Ultra does much better than the Mi 11—it does not shut down from overheating and is able to complete our benchmarks. However, there are very big fluctuations in performance, because the smartphone has to throttle down from time to time to avoid reaching extreme temperatures.

Snapdragon 888

In normal use, the Mi 11 Ultra cuts a very fine figure, because the thermal performance is not as important here. The system performance is on a very high level, and the applications start very quickly. The Xiaomi smartphone features very fast UFS 3.1 memory. However, the internal memory could have been faster. The Snapdragon 888 is capable of higher data transfer rates.
