Pros

  • Less than 40 minutes to a full charge
  • Low discharging currents in general
  • Great charging efficiency

Cons

  • Weak performance when using outdoors, especially when browsing social apps
  • Poor battery gauge accuracy; when screen shows 20% of battery power left, actual measured capacity is 14.5%

Xiaomi 14 demonstrated a great battery experience in our tests. Compared to its predecessor, Xiaomi 13, the device gained 5 points in our battery score, thanks to its improved performance in charging and efficiency.

In autonomy tests, Xiaomi 14 demonstrated an above-average performance. Under moderate usage, the device lasted more than 53 hours. The device also showed decent autonomy in individual test cases. However, the device struggled in outdoor tests, with the autonomy ranked at 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 less than 40 minutes, placing it among the best devices we have 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 a quick charging time, the device gained 8 hours and 12 minutes of autonomy from 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 discharging currents, except for listening to music under 4G conditions, meaning that the device is generally well-optimized. 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 relatively high.

Compared to other devices in the Premium segment ($600 – $799), the battery experience of the Xiaomi 14 ranked among the top devices, with its good autonomy and efficiency, and its excellent charging experience.

How Autonomy score is composed

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.

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.

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

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.

How Charging score is composed

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 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.

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.

How Efficiency score is composed

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.

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

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.
