Pros
- Fair autonomy when streaming videos
- Excellent autonomy when scrolling the social app on the go
- Low discharge current when using the camera on the go
- Very fast charging, only 18 minutes and 47 seconds to fill 80% of the battery capacity
- 8 hours and 20 seconds of autonomy recovered on average after a 5 minute charge
- Excellent charging and adapter efficiency, the best tested so far
versus
- Poor autonomy during calls and using GPS navigation on the go
- Very high discharge current during gaming and calls
- High residual consumption of the charger regardless of whether the smartphone is connected or not
The battery performance of the Nubia Red Magic 7 Pro ranked in the top half of our database.
When compared to all devices in the database, the RedMagic 7 Pro’s runtime score was slightly below average due to poor performance in very demanding use cases such as games, calls and GPS navigation. Battery life in moderate use was average, with decent performance when streaming videos and scrolling on social apps.
The real power of the Nubia was in charging, where it showed excellent performance with its 65W charger (global version). The efficiency of the charge, as well as the efficiency of the adapter, was outstanding, the best we have tested so far. The charger filled the large 5000mAh battery in just 28 minutes and 55 seconds, which is faster than what other more powerful chargers need to fill the same battery capacity.
Thanks to this powerful charger, the average autonomy recovered after a 5 minute charge was among the best at 8 hours and 20 minutes.
The disadvantage of all this charging power, however, was that the residual consumption of the charger was very high, regardless of whether the smartphone was connected or not.
When it came to efficiency, the discharge currents were also quite high, especially during games and calls. This is why the efficiency score is below average.
Compared to other devices in the Premium segment ($ 600 to $ 799), the Nubia RedMagic 7 Pro’s overall score is above average. Battery life was slightly above average, with the best secondary score on the go. The charge score was excellent, but the efficiency score was low due to the high discharge currents.
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.

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.

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.
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.
