We subjected the Oppo Reno8 Pro 5G to our rigorous SBMARK battery test suite to measure its performance in terms of range, charging and efficiency. In these test results, we will analyze how it fared in a variety of tests and several common use cases.
Overview
Key specs:
- Battery capacity: 4500mAh
- 80W charger (included)
- 6.7-inch, 1080 x 2412, 120Hz OLED display
- MediaTek 8100 MAX size (5 nm)
- Tested ROM / RAM combination: 256GB + 8GB
Pros
- Decent night management during the typical use scenario
- Good autonomy when scrolling 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 video
versus
- Battery life below average when streaming music
- Poor battery life during calls, taking photos and videos, and using GPS navigation on the go
- High residual power consumption of the charger when the device is fully charged and still connected
The battery of the Oppo Reno8 Pro 5G showed an overall average performance in our tests.
Runtime in a typical use scenario was average, aided by low overnight discharge currents, which averaged 1.67% per night. When the battery test ran in calibrated mode, the battery life of the device was also average, with the exception of streaming music, which consumed quite a bit of power, resulting in low battery life for this use case. .
Outdoor performance was poor, with activities such as calling, taking photos and videos, or using GPS navigation putting a strain on battery life. However, the autonomy while using the social apps has held up quite well.
Charging the Oppo Reno8 Pro 5G was excellent thanks to its 80W charger, which filled the 4500mAh battery in 38 minutes and 6 seconds. A 5-minute quick charge produced an average of 5 hours and 27 minutes of additional battery life.
The efficiency of the charge, as well as the efficiency of the power supply, was average. However, the remaining charger consumption when the device was fully powered and still plugged in was above average, which happens regularly with large chargers like this.
All discharge currents were average or slightly above average, except when streaming video, which means the device is well optimized for this use case.
The Oppo Reno8 Pro 5G’s overall score is in line with other devices in the database in the same price range ($ 600 to $ 799). Battery life was slightly above average, with good performance in a typical usage scenario and in calibrated tests. Charging performance was also decent, with slightly above average efficiency. However, the device’s on-the-go results were poor in this segment due to the call and camera use cases.
Test summary
Information on 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.

Light use
Active: 2h30 / day
49 hours
Moderate use
Active: 4 hours a day
30 hours
Intense use
Active: 7 hours a day

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 autonomy 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
99

Full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy the battery takes 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.
