We subjected the Xiaomi Redmi Note 11 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)
- 6.43-inch, 1080 x 2400, 90Hz OLED display
- Qualcomm Snapdragon 680 4G (6 nm)
- ROM / RAM combination tested: 128GB + 4GB
Pros
- 2.5 days of autonomy in moderate use, with excellent night management (only 1% lost on average per night)
- Decent performance on the go, especially when using the camera
- Above-average autonomy in calibrated mode
- Low residual consumption whether the device is connected or disconnected
Cons
- Poor autonomy when streaming videos on 4G
- High discharge current while playing
The Xiaomi Redmi Note 11 comes with the same battery and charger as its predecessor, the Redmi Note 10, so we expected its performance to be more or less similar. But a new chipset and higher screen refresh rate may have changed the game when it comes to battery performance.
With 2.5 days of battery life when used moderately, the performance of the Redmi Note 11 was above average, compared to other devices in our database. But it didn’t match the Redmi Note 10’s nearly 3 days of runtime. Weaker runtime performance was a factor that lowered the Redmi Note 11’s overall score compared to its predecessor.
The charging score of the Redmi Note 11 was also below average compared to other phones in the database. But compared to other phones in the essential price segment, the charging of the Redmi Note 11 ranked in the top 3, with excellent charging and adapter efficiency.
Test summary
About 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.

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 while following the same three-hour travel itinerary (on foot, by bus, by 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 battery life 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 it takes the battery 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.
Charge Up

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.
