We subjected the Xiaomi Redmi Note 11S 5G to our rigorous SBMARK battery test suite to measure its performance in terms of range, charging and efficiency. In these test results, we will analyze how it fared in a variety of tests and several common use cases.
Overview
Key specs:
- Battery capacity: 5000mAh
- 33W charger (included)
- 6.6-inch, 1080 x 2400, 90Hz LCD display
- MediaTek 810 size (6 nm)
- Tested ROM / RAM combination: 128GB + 6GB
Pros
- Exceptional autonomy during our typical use scenario (80 hours)
- Excellent performance when testing on the go
- Low discharge current when recalling calibrated settings
- Decent charging efficiency
- Excellent adapter efficiency
versus
- Struggles while streaming video
- High current discharge while playing
The overall battery performance of the Xiaomi Redmi Note 11S 5G earned it a place in the top 10 devices in our database. The default settings of the Redmi Note 11S 5G provided excellent performance, with 3 full days of battery life with moderate use and very good battery life during all tests on the go, especially when using social apps. But when it came to our calibrated tests, the performance was average. We believe this difference is due to the low brightness level of the display in default mode, which would provide more battery life but could affect the overall user experience.
The charging time of the Redmi Note 11S 5G was longer than average: it took 54 minutes to charge 80% of the large 5000 mAh battery and 1 hour and 20 minutes to fully charge it. The charging power curve showed that the maximum power was 29.6W, never reaching the advertised 33W. However, thanks to its excellent autonomy, the Redmi Note 11S 5G recovered on average 4 hours and 44 minutes of use after 5 minutes of charging, a figure higher than the average in our database.
Compared to other devices in the advanced segment, the Redmi Note 11S 5G is above average thanks to the factory default settings optimized for autonomy. But when measuring runtime with calibrated settings the device’s performance was average, as were charging performance and efficiency.
Test summary
Information on SBMARK battery tests: For the score 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. (See our introductory article and how we test articles for more details on our Smartphone Battery Protocol.)

How the autonomy score is composed
The range score is made up of three performance sub-scores: stationary, moving, and calibrated use cases. Each sub-score includes the results of a full range of tests to measure autonomy in all kinds of real-life scenarios.

Light use
Active: 2h30 / day

A robot housed in a Faraday cage performs a series of touch-based user actions during what we call our “typical use scenario” (TUS) – making calls, streaming video, etc. – 4 hours of active use over a 16-hour period, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device is discharged.

Using a smartphone on the go puts a strain on autonomy due to additional “hidden” needs, such as the continuous signaling associated with the selection of the cellular network. SBMARK Battery experts take the phone outdoors and perform a well-defined set of activities 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 ours robots repeatedly perform actions related to a specific use case (such as games, video streaming, etc.) at a time. Starting at an 80% charge, all devices are tested until they have consumed at least 5% of the battery charge.

How the Charge score is composed
Charging is completely part of the overall battery experience. In some situations where autonomy is minimal, knowing how fast you can charge becomes a problem. The SBMARK battery charge score consists of two secondary 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, 80 to 100% as shown by the user interface, and up 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.
The full charge time graph breaks down the time it takes to reach 80%, 100% and 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 graph here compares the average runtime gain from a 5 minute quick charge.

How the efficiency score is composed
The SBMARK energy efficiency score consists of two secondary scores, Charge up and Discharge rate, which combine both data obtained during a typical use scenario based on robots, calibrated tests and charge evaluation, taking into account the 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 charging and in use.

The secondary charge score is a combination of four factors: the overall efficiency of a full charge, relative to the amount of energy needed to fill the battery versus the energy the battery can provide; the efficiency of the travel adapter when it comes to transferring power from an outlet to the 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 secondary score evaluates the discharge rate of a battery during a test, which is independent of the battery capacity. It is the ratio of the capacity of a battery divided by its autonomy. A small capacity battery may have the same runtime as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
