We subjected the Xiaomi 12 Lite 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: 4300mAh
  • 67W charger (included)
  • 6.55-inch OLED display, 1080 x 2400, 120Hz
  • Qualcomm Snapdragon 778G 5G (6nm)
  • ROM / RAM combination tested: 128GB + 6GB

Pros

  • Low consumption when idle
  • Good autonomy during the call
  • Fast charging
  • Excellent charging efficiency
  • Low residual power consumption of the charger when the device is fully charged and still plugged in
  • Low overall discharge currents

Against

  • Low battery life when using the camera and GPS navigation
  • Long delay (28 minutes) between full charge shown on screen and full charge actually

The battery performance of the Xiaomi 12 Lite earned the device a slightly above-average overall score in our database.

Runtime performance was average, particularly when using the camera and GPS navigation. However, charging performance was excellent. Charging reached its advertised peak of 67W, but that level was only held for a few seconds before dropping to 37W. Charging efficiency, as well as power adapter efficiency, was also excellent. Overall, the discharge currents were low, meaning the software was well optimized.

Compared to devices in the high-end segment ($400-$599), the overall score of the Xiaomi 12 Lite is average. Its range when used moderately and the recharge time were also average, but the efficiency score was above average.

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.

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.

The time to full charge graph breaks down the time required 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 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.
