Pros
- Fast charging to full capacity
- Low discharge current during the night
- Excellent autonomy in outdoor navigation use case
- Great charging and adapter efficiency
Cons
- Relatively high residual power drain while the phone is still plugged in the charger
- Weak autonomy in both indoor and outdoor calling use case
Xiaomi 13T’s battery experience was quite average when compared to other devices we have tested. The device offered adequate autonomy in all our test cases. The charging experience and the efficiency results were in line with expectations.
Xiaomi 13T showed an above-average performance in autonomy, lasting more than two days if used moderately every day. The autonomy in outdoor navigation, video playback, and indoor gaming was also very good. However, the device’s performance was less optimal in the calling use case, whether indoors or outdoors.
The Xiaomi 13T was equipped with a 67W charger, which effectively decreased the duration to a full charge to around 52 minutes. The device also had a relatively accurate battery gauge. The 100% UI display represented 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 quick-boost tests were below average. Only 4 hours and 30 minutes of autonomy were gained after a 5-minute charge at 60% power.
The charger efficiency and the overall charge efficiency were decent, while the residual power drain while the device was plugged in was relatively high.
In summary, while the device may lack some standout features such as fast charging or durable autonomy, the battery performance of the Xiaomi 13T was well-balanced across various test aspects.
Compared to the other devices in the premium segment, the battery experience of Xiaomi 13T was right in the middle, while the charging efficiency was slightly below average.

Autonomy
Xiaomi 13T
195
Autonomy score is composed of three performance sub-scores: Home / Office, On the go, and 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.

Home/Office
Xiaomi 13T
221
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.
On the go
Xiaomi 13T
195
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 outdoors and perform a precisely defined set of activities while following the same three-hour travel itinerary (walking, taking the bus, the subway…) for each device
Calibrated
Xiaomi 13T
198
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.
Charging
Xiaomi 13T
218
Charging is fully part of the overall battery experience. In some situations where autonomy is at a minimum, knowing how fast you can charge becomes a concern. The DXOMARK Battery charging score is composed of two sub-scores, (1) Full charge and (2) Quick boost.
Full charge
Xiaomi 13T
224
Full charge tests assess the reliability of the battery power gauge; measure how long and how much power the battery takes to charge from zero to 80% capacity, from 80 to 100% as shown by the UI, and until an actual full charge.

Quick boost

212
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 chart here compares the average autonomy gain from a quick 5-minute charge.
Efficiency
Xiaomi 13T
154
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, calibrated tests and charging evaluation, taking into consideration the device’s battery capacity. DXOMARK calculate the annual power consumption of the product, shown on below graph, which is representative of the overall efficiency during a charge and when in use.
Charge up
Xiaomi 13T
205
The charge up sub-score is a combination of four factors: the overall efficiency of a full charge, related to how much energy you need to fill up the battery compared to the energy that 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 your phone is fully charged and still plugged into the charger; and the residual consumption of the charger itself, when the smartphone is disconnected from it. The chart here below shows the overall efficiency of a full charge in %.
Discharge
Xiaomi 13T
194
The discharge subscore rates the speed of a battery’s discharge during a test, which is independent of the battery’s capacity. It is the ratio of a battery’s capacity divided by its autonomy. A small-capacity battery could have the same autonomy as a large-capacity battery, indicating that the device is well-optimized, with a low discharge rate.
