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

Autonomy

Autonomy score is composed of three performance sub-scores: Stationary, On the go, and Calibrated use cases. Each sub-score comprises the results of a comprehensive range of tests for measuring autonomy in all kinds of real-life scenarios.

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

195
Using a smartphone on the go takes a toll on autonomy because of extra “hidden” demands, such as the continuous signaling associated with cellphone network selection, for example. DXOMARK Battery experts take the phone outdoors and perform a precisely defined set of activities while following the same three-hour travel itinerary (walking, taking the bus, the subway…) for each device
Calibrated

For this series of tests, the smartphone returns to the Faraday cage and our robots repeatedly perform actions linked to one specific use case (such as gaming, video streaming, etc.) at a time. Starting from an 80% charge, all devices are tested until they have expended at least 5% of their battery power.
Charging

Charging is fully part of the overall battery experience. In some situations where autonomy is at a minimum, knowing how fast you can charge becomes a concern. The DXOMARK Battery charging score is composed of two sub-scores, (1) Full charge and (2) Quick boost.
Full charge

Full charge tests assess the reliability of the battery power gauge; measure how long and how much power the battery takes to charge from zero to 80% capacity, from 80 to 100% as shown by the UI, and until an actual full charge.

Quick boost

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 chart here compares the average autonomy gain from a quick 5-minute charge.
Efficiency

154
The DXOMARK power efficiency score consists of two sub-scores, Charge up and Discharge rate, both of which combine data obtained during robot-based typical usage scenario, calibrated tests and charging evaluation, taking into consideration the device’s battery capacity. DXOMARK calculate the annual power consumption of the product, shown on below graph, which is representative of the overall efficiency during a charge and when in use.
The charge up sub-score is a combination of four factors: the overall efficiency of a full charge, related to how much energy you need to fill up the battery compared to the energy that 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 your phone is fully charged and still plugged into the charger; and the residual consumption of the charger itself, when the smartphone is disconnected from it. The chart here below shows the overall efficiency of a full charge in %.
Discharge

194
The discharge subscore rates the speed of a battery’s discharge during a test, which is independent of the battery’s capacity. It is the ratio of a battery’s capacity divided by its autonomy. A small-capacity battery could have the same autonomy as a large-capacity battery, indicating that the device is well-optimized, with a low discharge rate.
