We subjected the Xiaomi 12T Pro to our rigorous SBMARK battery test suite to measure its performance in terms of range, charging and efficiency. In these test results, we will analyze how it fared in a variety of tests and several common use cases.
Overview
Key specs:
- Battery capacity: 5000mAh
- 120W charger (included)
- 6.67-inch, 1220 x 2712, 120Hz OLED display
- Qualcomm Snapdragon 8+ Gen 1 (4 nm)
- Tested ROM / RAM combination: 256GB + 8GB
Pros
- Decent performance during calibrated tests
- Decent performance on the go
- Very fast charging
- 9 hours and 33 minutes of autonomy recovered after a 5-minute charge
- Excellent charging and charging efficiency
- Low discharge currents when streaming video and making calls
versus
- Poor battery life when streaming music
- High residual consumption of the charger itself
- High discharge currents in a typical use scenario
The Xiaomi 12T Pro battery showed an overall average performance in our tests, but its overall score was above average in our database.
The runtime in our typical usage scenario was average, with discharge currents above the average of our database.
Outdoor runtime was decent when scrolling through social apps and making calls. Other use cases, such as the camera and GPS navigation, were average. When tested in calibrated mode, the battery life of the device was decent, except for music streaming.
The charging performance of the Xiaomi 12T Pro was excellent thanks to its 120 W charger, which filled the large 5000 mAh battery in just 29 minutes and 5 seconds. A quick 5-minute charge produced 9 hours and 33 minutes of additional battery life, placing this device among the best in our database.
The efficiency of the charge was excellent, as was the efficiency of the power supply. The residual power consumption of the charger itself was high, about double the average, which happens regularly with such powerful chargers. Discharge currents were above average during the typical use scenario and when streaming music in calibrated mode. But discharge currents were low during our video streaming and call tests, indicating that the device is well optimized for such use cases.
Compared to devices in the same Premium price range, the Xiaomi 12T Pro’s overall score was excellent, bolstered by its decent runtimes, which included the best on-the-go score for the segment. But the efficiency was slightly below average due to the high discharge currents.
Test summary
Information on SBMARK battery tests: For the score and analysis in our smartphone battery reviews, SBMARK engineers perform a series of objective tests over a period of one week both indoors and outdoors. (See our introductory article and how we test articles for more details on our Smartphone Battery Protocol.)

How the autonomy score is composed
The autonomy score is made up of three sub-scores of performance: Home / Office, On the go, and Calibrated Use Cases. Each sub-score includes the results of a full range of tests to measure autonomy in all kinds of real-life scenarios.

A robot housed in a Faraday cage performs a series of touch-based user actions during what we call our “typical use scenario” (TUS) – making calls, streaming video, etc. – 4 hours of active use over a 16-hour period, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device is discharged.

Using a smartphone on the go puts a strain on autonomy due to additional “hidden” needs, such as the continuous signaling associated with the selection of the cellular network. SBMARK Battery experts take the phone outdoors and perform a well-defined set of activities while following the same three-hour travel itinerary (on foot, by bus, by subway …) for each device

For this series of tests, the smartphone returns to the Faraday cage and ours robots repeatedly perform actions related to a specific use case (such as games, video streaming, etc.) at a time. Starting at an 80% charge, all devices are tested until they have consumed at least 5% of the battery charge.

How the Charge score is composed
Charging is completely part of the overall battery experience. In some situations where autonomy is minimal, knowing how fast you can charge becomes a problem. The SBMARK battery charge score consists of two secondary scores, (1) Full charge and (2) Fast boost.
Full charge

Full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy the battery takes to charge from zero to 80% capacity, 80 to 100% as shown by the user interface, and up to an actual full charge.
The charging curves, in wired and wireless mode (if available) show the evolution of the battery level indicator as well as the energy consumption in watts during the charging phases towards full capacity.
The full charge time graph breaks down the time it takes to reach 80%, 100% and 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 graph here compares the average runtime gain from a 5 minute quick charge.

How the efficiency score is composed
The SBMARK energy efficiency score consists of two secondary scores, Charge up and Discharge rate, which combine both data obtained during a typical use scenario based on robots, calibrated tests and charge evaluation, taking into account the battery capacity of the device . SBMARK calculates the annual energy consumption of the product, shown in the graph below, which is representative of the overall efficiency during charging and in use.

The secondary charge score is a combination of four factors: the overall efficiency of a full charge, relative to the amount of energy needed to fill the battery versus the energy the battery can provide; the efficiency of the travel adapter when it comes to transferring power from an outlet to the phone; the residual consumption when the phone is fully charged and still connected to the charger; and the residual consumption of the charger itself, when the smartphone is disconnected from it. The graph below shows the overall efficiency of a full charge in%.
Discharge

The discharge secondary score evaluates the discharge rate of a battery during a test, which is independent of the battery capacity. It is the ratio of the capacity of a battery divided by its autonomy. A small capacity battery may have the same runtime as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
