Pros

  • Decent night management during the typical usage scenario
  • Good autonomy when scrolling on social apps on-the-go
  • Very fast charging
  • 5 hours 27 minutes of autonomy recovered on average after a 5-minute charge
  • Low discharge currents when streaming videos

Cons

  • Below-average autonomy when streaming music
  • Poor autonomy when calling, taking photos and videos, and using GPS navigation on-the-go
  • High residual consumption of the charger when the device is fully charged and still plugged in

The Oppo Reno8 Pro 5G battery showed an overall average performance in our testing.
Autonomy in a typical usage scenario was average, helped by the low discharge currents during the night, which averaged 1.67% per night. When battery testing was done in calibrated mode, the device’s autonomy was also average, except for streaming music, which drained quite a bit of power, resulting in low autonomy for this use case.
Outdoor performance was poor, with activities like calling, taking photos and videos, or using GPS navigation severely challenging the battery’s autonomy. However, autonomy when using social apps held up fairly well.
The Oppo Reno8 Pro 5G charging was excellent thanks to its 80W charger, which filled up the 4500 mAh battery in 38 minutes and 6 seconds. A quick 5-minute charge yielded on average 5 hours and 27 minutes of additional autonomy.
The charge efficiency, as well as the power adapter’s efficiency, was average. However, the residual consumption of the charger when the device was fully powered and still plugged in was higher than average, which regularly happens with chargers as big as this one.
All the discharge currents were either average or slightly above average, except when streaming videos, which means that the device is well-optimized for this use case.
The Oppo Reno8 Pro 5G’s global score falls in line with other devices in the database from the same price range ($600 to $799). Autonomy was slightly above average, with a good performance in a typical usage scenario and in calibrated tests. The charging performance was decent, too, with efficiency that was slightly above average. However, the device’s on-the-go results were poor in this segment because of the calling and camera use cases.

Test Summary

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. (See our introductory and how we test articles for more details about our smartphone Battery protocol.)

The following section gathers key elements of our exhaustive tests and analyses performed in DXOMARK laboratories. Detailed performance evaluations under the form of reports are available upon request. Do not hesitate to contact us.

How Autonomy score is composed

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.

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

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.

How Charging score is composed

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 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.

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.

How Efficiency score is composed

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

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.
