Pros

  • Good autonomy in gaming
  • Low residual power drain from the adapter
  • Below-average time required to fully charge the battery

Cons

  • More than 5% power decline at night in indoor use cases
  • Inaccurate battery gauge, with 20% indicated on the screen measuring only 16.9% actual capacity
  • Weak autonomy when phone is idle and the screen is off
  • High discharging currents in general

Xiaomi Redmi Note 13 5G  battery’s overall score was hampered by weak performances in autonomy and efficiency, when compared to its predecessor the Xiaomi Redmi Note 12 5G.

Despite its large 5000 mAh battery, the Xiaomi Redmi Note 13 5G’s autonomy performance struggled in moderate usage, with the device lasting  50 hours and 24 minutes, which ranked the device in the bottom half of our database.  In addition, the device’s loss of  5.3% of power per night in our indoor test was relatively high compared to other devices, indicating an elevated consumption even during rest mode. Moreover, the device’s battery gauge was inaccurate. As the screen displayed 20% of power left, our experts measured actual remaining power of 16.9%.  However, autonomy was relatively decent during gaming and intense usage.

Equipped with a 33W charger, the Xiaomi Redmi Note 13 5G achieved a full charge in 1 hour 24 minutes, which was decent. However, the device was unable to regain significant autonomy in a 5-minute boost charging session, yielding less than 4 hours because of high discharging currents in the home/office test and the relatively low-powered charger.

In terms of efficiency, the Xiaomi Redmi Note 13 5G ranked below average for Charge-up efficiency and Discharge efficiency. Almost a quarter of the energy was wasted during the charging process, and the residual power drain was higher than average while the device was still connected. However, the adapter efficiency was relatively good, and the residual power drain when the device was disconnected was very low. On the other hand, the discharging current was generally higher than average, especially when idling under Wi-Fi conditions, indicating inefficient use of energy.

Compared to other devices in the Advanced segment (< $299), the Xiaomi Redmi Note 13 5G did not outperform many devices, primarily because of its poor autonomy and efficiency performances.

Test Summary

About DXOMARK Battery tests: For scoring and analysis in our smartphone battery reviews, DXOMARK engineers perform a variety of objective tests over a week-long period both indoors and outdoors. (See our introductory and how we test articles for more details about our smartphone Battery protocol.)

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.
