We subjected the Xiaomi 12T 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
- MediaTek Dimensity 8100-Ultra (5 nm)
- Tested ROM / RAM combination: 256GB + 8GB
Pros
- Decent performance on the go
- Very fast charging
- 9 hours and 15 minutes of autonomy recovered after a 5 minute charge
- Excellent charging efficiency
versus
- Poor autonomy while playing
- High residual consumption of the charger
- High discharge currents overall
The Xiaomi 12T’s battery performance was average overall, although the device’s overall score is slightly above average, thanks to its charging capabilities.
Runtimes were average in our typical usage scenario thanks to the large 5000mAh battery, although discharge currents were above the average in our database.
Outdoor performance was decent thanks to the excellent autonomy while scrolling through the social apps. The other use cases, however, were average.
When tested in calibrated mode, the battery life of the device was also average, except for games, which consumed a lot of power.
Charging performance, on the other hand, was excellent thanks to its 120W charger, which filled the capacious battery in 32 minutes and 52 seconds. A quick 5-minute charge produced 9 hours and 15 minutes of additional battery life, placing this device among the best in our database.
Charge efficiency was excellent, but PSU efficiency was slightly below average. The residual consumption of the charger when the device was fully charged and still connected was above average, which happens regularly with large chargers like this. The residual consumption of the charger was also high, about double the average.
All discharge currents were above average, especially during gaming, which means this device is not optimized for such a use case.
Compared to devices in the same high-end price range ($ 400 to $ 599), the Xiaomi 12T’s overall score was above average. The charging score was excellent, but the range was below average, despite a decent performance on the go. The efficiency was poor due to the high discharge currents, although it achieves the best segment score in charge.
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.
