We subjected the Xiaomi 13 to our rigorous SBMARK Battery test suite to measure its performance in terms of range, charging and efficiency. In these test results, we’ll analyze how it performed in a variety of tests and several common use cases.
Overview
Key Specifications:
- Battery Capacity: 4500mAh
- 67W charger (included)
- 6.36-inch, 1080 x 2400, 120Hz OLED display
- Qualcomm Snapdragon 8 Gen2 (4nm)
- ROM / RAM combination tested: 128GB + 8GB
Pros
- Good battery life when streaming video
- Very fast wired charging with 46 minutes and 20 seconds to recharge the battery
- Very fast wireless charging, taking 56 minutes to recharge the battery
- Low residual power consumption of the wired charger
- Good wired and wireless charging efficiency
Against
- Poor battery life during music streaming and calls
- High discharge current during the call in our specific use tests
- High residual power consumption when the device is fully charged and still on the wireless cradle
The Xiaomi 13 battery achieved a very good overall score, much better than its predecessor Xiaomi 12.
This is mainly due to the decent battery life, which lasted an impressive 53 hours and 50 minutes with moderate use. The device showed good performance when streaming video and when using it on the go, but the battery life was rather 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. Additionally, a 5-minute quick charge provided a runtime of 5 hours and 28 minutes on average, better than the average in our database.
Wired and wireless charging efficiencies were good, but residual power consumption when the device was fully charged and still on the wireless cradle was high. The discharge currents were all below average especially when streaming video except during calls and streaming music which means the device is well optimized.
When compared to devices in the premium segment, the Xiaomi 13 ranks third in the database. It showed good autonomy (especially on the go, where it gets a maximum score for the segment), excellent efficiency and a good charging experience.

How the Autonomy score is composed
The Battery Life Score is composed of three performance sub-scores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes results from a full range of tests to measure range in all kinds of real-life scenarios.

Active: 2h30/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 a 16 hour period, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device runs out.

Using a smartphone on the go has a negative impact on range due to additional “hidden” demands, such as continuous signaling associated with cellular network selection. SBMARK Battery experts take the phone outdoors and perform a series of precisely defined activities following the same three-hour travel itinerary (walking, taking the bus, the subway…) for each device

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

How the recharge score is composed
Charging is fully part of the overall battery experience. In some situations where range is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score consists of two subscores, (1) Full Charge and (2) Fast Boost.

The full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy it takes for the battery to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and to an actual full charge.
The charging curves, in wired and wireless mode (if available) showing the evolution of the battery level indicator as well as the energy consumption in watts during the charging phases towards full capacity.

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 range gain with a 5-minute quick charge.

How the efficiency score is composed
The SBMARK Energy Efficiency Score consists of two subscores, charge rate and discharge rate, which combine both data obtained during a typical robot-based usage scenario, calibrated testing and charge rating, taking into consideration battery capacity of the device. SBMARK calculates the product’s annual energy consumption, shown in the graph below, which is representative of overall efficiency during a charge and when in use.

The secondary charge score is a combination of four factors: the overall efficiency of a full charge, relating to the amount of energy required to recharge the battery compared to the energy the battery can supply; the efficiency of the travel adapter when it comes to transferring power from an outlet to your phone; the remaining 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 sub-discharge score evaluates how quickly a battery discharges during a test, which is independent of battery capacity. It is the ratio between the capacity of a battery and its autonomy. A small capacity battery may have the same run time as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
