We subjected the Xiaomi 14 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: 4610mAh
- 90W charger (not included)
- 6.36-inch OLED display, 1200 x 2670, 120 Hz
- Qualcomm Snapdragon 8 Gen 3 (4nm)
- Tested ROM/RAM combination: 512GB + 12GB
Pros
- Less than 40 minutes for a full charge
- Low discharge currents in general
- Great charging efficiency
Against
- Weak performance when using outdoors, especially when browsing social apps
- Poor accuracy of the battery indicator; when the screen shows 20% battery remaining, the actual measured capacity is 14.5%
The Xiaomi 14 demonstrated a very good battery experience in our tests. Compared to its predecessor, the Xiaomi 13, the device earned 5 points in our battery score, thanks to improved performance in terms of charging and efficiency.
In battery tests, Xiaomi 14 demonstrated above-average performance. With moderate use, the device lasted more than 53 hours. The device also showed decent battery life in individual test cases. However, the device struggled in outdoor tests, with battery life ranked in the bottom half among our tested devices.
Charging is where the Xiaomi 14 showed the biggest improvement over its predecessor. The device supports up to 80W of charging power, which helped the battery reach a full charge in under 40 minutes, placing it among the best devices we’ve tested so far. The Xiaomi 14’s wireless charging experience was also impressive, taking less than 53 minutes to reach a full charge. In addition to the fast charging time, the device gained 8 hours and 12 minutes of battery life with a 5-minute quick charge, almost three hours more than its predecessor, placing it in the top half of the database.
In terms of efficiency, the Xiaomi 14 showed generally low discharge currents, with the exception of listening to music in 4G conditions, which means that the device is generally well optimized. Wired and wireless charging efficiency was good, but the remaining power consumption when the device was fully charged and still on the wireless stand was relatively high.
Compared to other devices in the Premium segment ($600 – $799), the battery experience of the Xiaomi 14 ranked among the best devices, with its good battery life and efficiency, and its excellent charging experience.
Test summary
Information on SBMARK battery tests: For scoring and analysis in our smartphone battery reviews, SBMARK engineers perform a series of objective tests over a period of one week both indoors and outdoors.

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.

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

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 to an actual full charge.
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.

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, charging speed and discharging speed, which combine both data obtained during a typical robot-based usage scenario, calibrated tests and charging evaluation, 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.
