Appearing on the market in March 2021 and fitting into our Premium ($600-$799) segment, the Nubia RedMagic 6 Pro comes with some special features, including an ICE 6.0 Multi-dimensional Cooling System, a game space, and a display with a maximum refresh rate of 165 Hz. Let’s see how it fared in our comprehensive array of Battery performance tests.

Key specifications:

  • Battery capacity: 4500 mAh
  • 120W charger
  • 6.8-inch, 1080 x 2400, 165 Hz OLED display
  • Qualcomm Snapdragon 888 5G (5 nm) chipset
  • Tested ROM / RAM combination: 256 GB + 12 GB

About DXOMARK Battery tests: For scoring and analysis in our smartphone battery reviews, DXOMARK engineers perform a variety of objective tests over a week-long period both indoors and outdoors. This article highlights the most important results of our testing. (See our introductory and how we test articles for more details about our smartphone Battery protocol.)

Test summary

Nubia RedMagic 6 Pro


  • Outstanding charging experience
  • Very high gain in autonomy after a 5-minute charge
  • Very good autonomy for video streaming and playback and for gaming


  • Less than two days of autonomy with moderate use
  • Poor performance in Navigation and Spotify

The Nubia RedMagic 6 Pro ties with the Oppo Find X3 Pro for first place overall in this comparison. The Nubia owes much of its standing to its outstanding Charging performance, with its 120W charger giving it a distinct advantage over its competitors. It also fared well among its rivals for Efficiency.

We compared the Redmagic 6 Pro’s performance in several key categories with the ultra-premium (800€ and higher) Samsung Galaxy S21 Ultra 5G (Snapdragon), with another Premium device, the aforementioned Oppo Find X3 Neo, and with the High-End (400-599€) Realme GT 5G; battery capacity, tested charger, display type and resolution, and processor specifications for the four devices are shown in the table below.

Autonomy (54)

How long a battery charge lasts depends not only on battery capacity but also on other aspects of the phone’s hardware and software. The DXOMARK Battery autonomy score is composed of three performance sub-scores: (1) Stationary, (2) On the go, and (3) 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.

Active: 2h30/day

Autonomy was the only category in which the RedMagic 6 Pro failed to impress.

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. 

The Nubia RedMagic 6 Pro lasted 46 hours 21 minutes in our TUS testing, which is around 10 hours less than its competitors, despite having the same size battery as the Samsung and Oppo devices.

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 outside and perform a precisely defined set of activities while following the same three-hour travel itinerary for each device.

A mixed bag here, as the RedMagic 6 Pro put in an average performance in social apps and call, an impressive performance for camera, and a very low performance for navigation.

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.

In a controlled environment with a set light intensity and cooling fan off, the Nubia leads the pack in autonomy for all tests with screen on — gaming, video playback, and video streaming via 4G and Wi-Fi.

Charging (117)

The DXOMARK Battery charging score is composed of two sub-scores, Full charge and Quick boost. Full charge tests assess the reliability of the battery power gauge; measure how long it takes to charge a battery from zero to 80% capacity and from 80 to 100%; and measure how long and how much power the battery takes to go from an indicated 100% to an actual 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.

By plugging in the RedMagic 6 Pro for 5 minutes with less than a 40% battery charge remaining, users will gain an impressive 10 hours of autonomy.

Efficiency (89)

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 testing, outdoor mobility testing, charging evaluation, and power measurements, and then take into consideration the device’s battery capacity.

Despite a disappointing TUS performance among its competitors, the Nubia RedMagic 6 Pro takes top honors here.

Charge up

The RedMagic 6 Pro has good charge efficiency and adapter efficiency, but its residual power drains (both plugged in and unplugged) are very high.

The Nubia device easily leads its rivals in this category, as its discharge current is very well controlled for all screen-on tests.


While falling short in Autonomy, the Nubia RedMagic 6 Pro is an efficient device with such fast and powerful charging that it comes with a cooling system to avoid damaging the battery. A great smartphone for users who need to charge quickly.
