We subjected the Xiaomi Redmi Note 12 Pro+ 5G to our rigorous SBMARK Battery test suite to measure its performance in terms of autonomy, charging and efficiency. In these test results, we’ll analyze how it performed in a variety of tests and several common use cases.
Overview
Key Specifications:
- Battery Capacity: 5000mAh
- 120W charger (included)
- 6.67-inch, 1080 x 2400, 120Hz OLED display
- MediaTek Dimension 1080 (6nm)
- ROM / RAM combination tested: 256GB + 8GB
Pros
- Exceptional autonomy recovered after a quick 5-minute recharge
- Only about 31 minutes to fully charge the battery
- Decent battery life while gaming
Against
- Above-average discharge currents in almost all use cases
- Low autonomy during the call
- Inaccurate battery gauge with 17.4% of actual battery capacity shown as 20%
- Below average overall autonomy
The Xiaomi Redmi Note 12 Pro+ 5G achieved a good overall score above the average in our database. Compared to the Redmi Note 12 Pro 5G, it offers an excellent charging experience thanks to its 120W charger but with a small weakness in terms of autonomy and efficiency.
The Redmi Note 12 Pro+ 5G battery lasted just under 2.5 days with moderate use, which is just above the average in our database. When testing specific use cases, battery life was slightly below average overall and decent when gaming, but the device showed mixed results during calls.
The main selling point of the Redmi Note 12 Pro+ 5G device is its charging performance. Charging took exactly 30 minutes and 43 seconds to fully recharge the battery, while a 5-minute quick charge provided an additional 10 hours and 27 minutes of battery life, giving the device its best quick charge score yet. However, it took almost 5 minutes for the device to come out of deep discharge, the state where the battery is empty. That’s a long time when compared to its full charge time of almost 31 minutes and when compared to other phones with similar charging powers. This could significantly affect the user who has to wait 5 minutes just to turn on a device with a low battery.
The charging efficiency of the device and its adapter was very good. But the remaining power consumed by the 120W charger whether the fully charged device was plugged in or not was above average. The battery also discharged higher than average discharge currents in almost all use cases, especially during calls, indicating that the device is not well optimized.
When compared to other devices in the high-end segment ($400-$599), the Xiaomi Redmi Note 12 Pro+ 5G also ranked above average. However, its efficiency score was below average for this segment, even though its range score was above average. The device’s charging performance was among the top three we’ve tested for this segment.

How the Autonomy score is composed
The Battery Life Score is composed of three performance sub-scores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes results from a full range of tests to measure range in all kinds of real-life scenarios.

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 a 16 hour period, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device runs out.

Using a smartphone on the go has a negative impact on range due to additional “hidden” demands, such as continuous signaling associated with cellular network selection. SBMARK Battery experts take the phone outdoors and perform a series of precisely defined 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 to ours bots repeatedly perform actions related to a specific use case (like gaming, video streaming, etc.) at a time. Starting with an 80% charge, all devices are tested until they have used at least 5% battery power.

How the recharge score is composed
Charging is fully part of the overall battery experience. In some situations where range is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score consists of two subscores, (1) Full Charge and (2) Fast Boost.

The full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy it takes for the battery to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and to an actual full charge.
The charging curves, in wired and wireless mode (if available) showing 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 graph breaks down the time required 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 range gain with a 5-minute quick charge.

How the efficiency score is composed
The SBMARK Energy Efficiency Score consists of two subscores, charge rate and discharge rate, which combine both data obtained during a typical robot-based usage scenario, calibrated testing and charge rating, taking into consideration battery capacity of the device. SBMARK calculates the product’s annual energy consumption, shown in the graph below, which is representative of overall efficiency during a charge and when in use.

The secondary charge score is a combination of four factors: the overall efficiency of a full charge, relating to the amount of energy required to recharge the battery compared to the energy the battery can supply; the efficiency of the travel adapter when it comes to transferring power from an outlet to your phone; the remaining 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 %.

The sub-discharge score evaluates how quickly a battery discharges during a test, which is independent of battery capacity. It is the ratio between the capacity of a battery and its autonomy. A small capacity battery may have the same run time as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
