Scoring
Sub-scores and attributes included in the calculations of the global score.

Xiaomi 13
Key performances
These key points are derived from the lab measurements during testing and do not figure into the overall score. The lab measurements, however, are used for the overall score.
Pros
- Good autonomy when streaming videos
- Very fast wired charging with 46 minutes, 20 seconds to replenish the battery
- Very fast wireless charging, taking 56 minutes to replenish the battery
- Low residual power drain of the wired charger
- Good wired and wireless charge efficiencies
Cons
- Poor autonomy when streaming music and calling
- High discharge current when calling in our specific usage tests
- High residual power drain when the device is fully charged and still on the wireless stand
The Xiaomi 13 battery achieved a very good global score, much better than its predecessor the Xiaomi 12.
This was mainly due to decent autonomy, which lasted a good 53 hours and 50 minutes when used moderately. The device showed good performances when streaming videos and when used on-the-go, but the autonomy was quite poor when listening to music.
The charging experience was very strong for both wired and wireless chargers. Both charging methods were very fast, with the wired one taking less than 47 minutes, and the wireless 56 minutes to fully charge the battery. Moreover, a quick 5-minute charge provided an autonomy of 5 hours and 28 minutes on average, which was better than our database average.
The wired and wireless charge efficiencies were good, but the residual power drain when the device was fully charged and still on the wireless stand was high. Discharge currents were all below average, especially when streaming videos, except when calling and streaming music, meaning that the device is well-optimized.
When compared with devices from the Premium segment, the Xiaomi 13 ranks in third place in database. It showed good autonomy (especially on the go, where is achieved a top score for the segment), excellent efficiency and a good charging experience.

Autonomy
Xiaomi 13
188
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.
Battery Life (moderate)

Home/Office
Xiaomi 13
213
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 13
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 13
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 13
181
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 13
184
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.
Charging Time 0-80%

Quick boost

182
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 13
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 13
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 13
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.
