Autonomy (53)
How long a battery charge lasts depends not only on battery capacity but also on other aspects of the phone’s hardware and software. The DXOMARK Battery autonomy score is composed of three performance sub-scores: (1) Stationary, (2) On the go, and (3) Calibrated use cases. Each sub-score comprises the results of a comprehensive range of tests for measuring autonomy in all kinds of real-life scenarios.

A robot housed in a Faraday cage performs a set of touch-based user actions during what we call our “typical usage scenario” (TUS) — making calls, video streaming, etc. — 4 hours of active use over the course of a 16-hour period, plus 8 hours of “sleep.” The robot repeats this set of actions every day until the device runs out of power.
The Mi 11 Ultra is the clear winner in the autonomy battle during our TUS testing, lasting 56 hours 28 minutes, which is 10 hours more than its rivals. The Xiaomi device lost more than 2% its battery charge during the night, compared to the Find X3 Pro’s 1.5% and the Samsung Galaxy S21 Ultra 5G (Exynos)’s hefty 4%.

Best: Samsung Galaxy M51 (96)
Using a smartphone on the go takes a toll on autonomy because of extra “hidden” demands, such as the continuous signaling associated with cellphone network selection, for example. DXOMARK Battery experts take the phone outside and perform a precisely defined set of activities while following the same three-hour travel itinerary for each device.
Except for GPS, Xiaomi device achieved an average performance in all use cases, but it did well enough in Call to earn a better overall mark in this sub-attribute than its rivals.

Best: Samsung Galaxy M51 (100)
For this series of tests, the smartphone returns to the Faraday cage and our robots repeatedly perform actions linked to one specific use case (such as gaming, video streaming, etc.) at a time. Starting from an 80% charge, all devices are tested until they have expended at least 5% of their battery power.
Apart from gaming, where it lasted considerably longer than its rivals, the Mi 11 Ultra put in a largely lackluster performance, but still beat the Find X3 Pro and the Galaxy S21 Ultra 5G (Exynos).

Charging (96)
The DXOMARK Battery charging score is composed of two sub-scores, Full charge and Quick boost. Full charge tests assess the reliability of the battery power gauge; measure how long it takes to charge a battery from zero to 80% capacity and from 80 to 100%; and measure how long and how much power the battery takes to go from an indicated 100% to an actual full charge. With the phone at different charge levels (20%, 40%, 60%, 80%), Quick boost tests measure the amount of charge the battery receives after being plugged in for 5 minutes.
The Xiaomi Mi 11 Ultra’s 67W charger lets it outperform the Samsung, but does not quite match the performance of the Oppo Find X3 Pro at 65W.

The Mi 11 Ultra needs only 44 minutes to completely fill its 5000 mAh battery, which is significantly faster than the Samsung, and only 7 minutes behind the Oppo. However, the Mi 11 Ultra is the fastest for wireless charging, requiring only an hour to fully charge its battery — a better performance than either the Find X3 Pro at 1 hour 43 minutes or the Samsung S21 Ultra (Exynos) at 2 hours 32 minutes.

Efficiency (59)
The DXOMARK power efficiency score consists of two sub-scores, Charge up and Discharge rate, both of which combine data obtained during robot-based typical usage scenario testing, outdoor mobility testing, charging evaluation, and power measurements, and then take into consideration the device’s battery capacity.
The Mi 11 Ultra’s performance is below average for efficiency when compared to other ultra-premium devices in our database.
