We subjected the Xiaomi Redmi Note 13 5G 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
- MediaTek Dimensity 6080 (6nm)
- Tested ROM/RAM combination: 128GB + 6GB
Pros
- Good autonomy in gaming
- Low residual power consumption from the adapter
- Less than average time needed to fully charge the battery
Against
- Power drop greater than 5% during the night when used indoors
- Inaccurate battery indicator, with 20% indicated on screen measuring only 16.9% of actual capacity
- Weak battery life when the phone is idle and the screen is off
- High discharge currents in general
The overall Xiaomi Redmi Note 13 5G battery score was hampered by poor performance in terms of battery life and efficiency, compared to its predecessor, the Xiaomi Redmi Note 12 5G.
Despite its large 5000 mAh battery, the Xiaomi Redmi Note 13 5G’s battery life struggled under moderate usage, with the device lasting for 50 hours and 24 minutes, which ranked the device in the bottom half of our database. Furthermore, the device’s power loss of 5.3% per night in our indoor test was relatively high compared to other devices, indicating high consumption even in sleep mode. Additionally, the device’s battery indicator was inaccurate. Since the screen displayed 20% charge remaining, our experts measured the actual remaining power as 16.9%. However, battery life was relatively decent during gaming and heavy use.
Equipped with a 33W charger, the Xiaomi Redmi Note 13 5G achieved a full charge in 1 hour and 24 minutes, a decent result. However, the device was unable to regain significant battery life in a 5-minute boost charging session, achieving less than 4 hours due to the high discharge currents in the home/office test and the relatively low-power charger .
In terms of efficiency, the Xiaomi Redmi Note 13 5G ranked below average for charging efficiency and discharging efficiency. Nearly a quarter of the energy was wasted during the charging process, and the remaining power consumption was higher than average while the device was still connected. However, the efficiency of the adapter was relatively good and the residual power consumption when the device was unplugged was very low. On the other hand, the discharge current was generally higher than average, especially at idle under Wi-Fi conditions, indicating inefficient use of power.
Compared to other devices in the Advanced segment (< $299), the Xiaomi Redmi Note 13 5G did not outperform many devices, mainly due to its poor battery life and efficiency.
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.
63 hours
Light usage
Active: 2h30/day
50 hours
Moderate use
Active: 4 hours a day
36 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 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.
