We subjected the Xiaomi 13T to our rigorous SBMARK Battery test suite to measure its performance in terms of battery life, charging and efficiency. In the results of these tests, we will analyze how it performed in a series of tests and in several common use cases.
Overview
Key Specifications:
- Battery capacity: 5000mAh
- 67W charger (included)
- 6.73-inch OLED display, 1080 x 2400, 144 Hz
- MediaTek Dimensity 8200 Ultra (4nm)
- Tested ROM/RAM combination: 256GB + 8GB
Pros
- Fast charging to full capacity
- Low discharge current at night
- Excellent autonomy when using outdoor navigation
- Excellent charging efficiency and adapter
Against
- Relatively high residual power consumption while the phone is still connected to the charger
- Weak autonomy when using both internal and external calls
The Xiaomi 13T’s battery experience was pretty average compared to other devices we’ve tested. The device offered adequate battery life in all our test cases. The charging experience and efficiency results were in line with expectations.
The Xiaomi 13T showed above-average performance in terms of battery life, lasting more than two days when used moderately every day. Battery life in outdoor navigation, video playback and indoor games is also very good. However, the device’s performance was less than optimal in the calling use case, both indoors and outdoors.
The Xiaomi 13T was equipped with a 67W charger, which effectively reduced the full charging time to around 51 minutes. The device also had a relatively accurate battery indicator. The UI display at 100% accounted for more than 97% of the total capacity, ranking the device at the top of our database. On the other hand, even though the charger was quite powerful, the results of the quick-boost tests were below average. After a 5 minute charge at 60% power you only get 4 hours and 30 minutes of battery life.
Charger efficiency and overall charging efficiency were decent, while residual power consumption while the device was plugged in was relatively high.
In summary, although the device may lack some distinctive features such as fast charging or long-lasting battery life, the battery performance of the Xiaomi 13T was well balanced under the various aspects of the test.
Compared to other devices in the premium segment, the battery experience of the Xiaomi 13T was average, while the charging efficiency was slightly below average.

How the autonomy score is composed
The battery life score is made up of three performance subscores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes the results of a full range of tests to measure battery life in all types of real-life scenarios.
76 hours
Light usage
Active: 2h30/day
54 hours
Moderate use
Active: 4 hours a day
34 hours
Intense use
Active: 7 hours a day
Home office
A robot housed in a Faraday cage performs a series of touch-based user actions during what we call our “Typical Usage Scenario” (TUS) (making calls, streaming video, etc.) – 4 hours of active use over the course of 16 hours. -a period of one hour, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device runs out of power.

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

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

How the charging score is made up
Charging is a full part of the overall battery experience. In some situations where battery life is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score is made up of two sub-scores, (1) Full Charge and (2) Quick 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, from 80 to 100% as shown by the user interface, and until actually fully charged.
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 time to full charge table breaks down the time needed to reach 80%, 100%, and full charge.

With the phone at different charge levels (20%, 40%, 60%, 80%), the Quick Boost tests measure how much charge the battery receives after being plugged in for 5 minutes. The graph here compares the average battery life gain with a 5 minute fast charge.

How the efficiency score is composed
The SBMARK Energy Efficiency Score is composed of two sub-scores, Charge Rate and Discharge Rate, both of which combine data obtained during a typical robot-based usage scenario, calibrated tests, and charge rating, taking into account 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 a charge and when in use.

The charging subscore is a combination of four factors: the overall efficiency of a full charge, related to the amount of energy needed to fill the battery compared to the energy the battery can provide; the efficiency of the travel adapter when it comes to transferring power from an outlet to your 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 subscore evaluates how quickly a battery discharges during a test, which is independent of the battery’s capacity. It is the ratio between the capacity of a battery divided by its autonomy. A small capacity battery may have the same battery life as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
