We subjected the Xiaomi Redmi Note 13 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: 5000mAh
- 33W charger (included)
- 6.67-inch OLED display, 1080 x 2400, 120 Hz
- Qualcomm Snapdragon 685 (6nm)
- Tested ROM/RAM combination: 256GB + 8GB
Pros
- Great autonomy, especially in video streaming and calls
- Accurate battery indicator; The 100% displayed on the screen while charging measured 97.7% of the actual charged capacity
- Very high adapter efficiency, with low consumption of residual power from the mains
Against
- Poor battery life outdoors while browsing social apps
- Limited autonomy regained thanks to the 5-minute charging boost
- Relatively high discharge currents during gaming and at idle with the screen off
The battery of the Xiaomi Redmi Note 13 had an overall average performance, but this version showed much higher performance in terms of autonomy and efficiency than its 5G counterpart, the Redmi Note 13 5G.
With moderate use, the Xiaomi Redmi Note 13 lasted more than 56 hours, compared to 50 and a half hours for the 5G version. The device showed great battery life in most cases of outdoor use, except when browsing social apps. In most calibrated use cases, the battery life of the Redmi Note 13 was around average, while the battery life of video streaming and calls was significantly above average.
The Redmi Note 13’s 33W charger, which comes with the device, was able to fully charge the phone in 1 hour and 12 minutes, placing it in the top half of our database. However, the charging boost performance was limited by the power of the charger; a 5-minute charge yielded just 3 hours and 44 minutes of additional battery life.
The Xiaomi Redmi Note 13 showed slightly below average performance in the efficiency tests. The reason was related to the relatively poor efficiency at full charge of 75.7%. However, the Xiaomi Redmi Note 13’s adapter was relatively great, with an adapter efficiency of 92% and lower than average residual power consumption, regardless of whether the device was still connected or not. The discharge currents of the Xiaomi Redmi Note 13 were average, with the exception of video streaming, which was much lower. But the discharge currents during gaming and idling were relatively higher than average.
Compared to other devices in the Essential segment (<$199), the Xiaomi Redmi Note 13 ranked in the top half, thanks to its excellent results in terms of battery life.
Test summary

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.
81h
Light usage
Active: 2h30/day
56 hours
Moderate use
Active: 4 hours a day
35 hours
Intense use
Active: 7 hours a 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 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 until actually fully charged.
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.
The time to full charge table breaks down the time needed to reach 80%, 100%, and full charge.

With your 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.
