About DXOMARK Battery tests: For scoring and analysis in our smartphone battery reviews, DXOMARK engineers perform a variety of objective tests over a week-long period both indoors and outdoors. This article highlights the most important results of our testing. (See our introductory and how we test articles for more details about our smartphone Battery protocol.)

Thanks to its big battery (5000 mAh) and its incredibly fast charger (120W), the Xiaomi 11T Pro achieves a score that places it in the top half of the DXOMARK Battery database and second place in its segment.
We compared the Xiaomi 11T Pro’s performance in several key categories with three other devices in our Premium segment, the Oppo Reno6 Pro 5G, the OnePlus 9, and the Apple iPhone 13; battery capacity, tested charger, display type, and resolution, and processor specifications for the four devices are shown in the table below.

Autonomy (61)
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.
The Xiaomi and Apple devices share the same Autonomy score of 61, even though the 11T Pro has a much bigger battery than the iPhone 13 (5000 mAh vs. 3227 mAh). However, the Oppo takes top honors in this category by one point.
The 11T Pro’s battery gauge is not accurate. When the UI shows 20% charge remaining, the true charge remaining is only 14.7%.

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 Xiaomi 11T Pro racked up 61 hours 38 minutes in our TUS test, besting the other devices in this comparison.

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.
Another best of the batch performance in this category, thanks to the Xiaomi’s impressive performance in calls and social apps. But the iPhone did much better in navigation, and the OnePlus 9 Pro did better in camera.

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.
The Xiaomi 11T Pro turned in a below-average performance in every category except for call and gaming, with a much lower performance in music streaming compared to its rivals.
Charging (113)
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 11T Pro’s charging performance was simply outstanding — it is the best device our experts have tested to date. With its 20W charger, the iPhone 13 lags far behind its rivals.
Unlike the OnePlus and Apple devices, neither the Xiaomi nor the Oppo offer wireless charging.

The Xiaomi shares the top score with the OnePlus 9 (thanks to the latter’s wireless charger, which earned it bonus points). The 11T Pro fully charges in 30 minutes and reaches 80% in only 18 minutes. Its only drawback with regard to wired charging is that when it begins charging at 0%, it takes 3.5 minutes to get out of slow charging mode and reach peak charging, which impacts the full charge duration. (Phones typically exit slow charging in a few seconds.)
The Xiaomi charger’s 120W peak lasts only 15 seconds, but the charger plateaus at 75W for 12 minutes, which is huge.

The 11T Pro is far ahead of its competitors, providing on average 10 hours 30 minutes of use after charging for only 5 minutes. By comparison, the iPhone lasts on average only 2 hours 48 minutes following a 5-minute charge.

Efficiency (65)
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 Xiaomi device comes in last for Efficiency among its rivals in this review.

The Xiaomi bests the iPhone for charge-up efficiency (80.1% vs. 64.3%), but the Oppo and the OnePlus outperform the other two devices, with 82.2% and 81.3%, respectively.
The 11T Pro’s residual power drain when unplugged very high at 112 mW, whereas the iPhone’s is only 33 mW.
Discharge

Given the Xiaomi 11T Pro’s quite poor results in our calibrated tests, it is in last place here.
Conclusion
Despite efficiency results that point to the need for better optimizing and despite no wireless charging, the Xiaomi 11T Pro’s results for Autonomy and Charging add up to an impressive performance.
