We subjected the Oppo Reno12 to our rigorous SBMARK Battery test suite to measure its performance in terms of battery life, charging and efficiency. In the results of these tests, we will analyze how it performed in a series of tests and in several common use cases.
Overview
Key Specifications:
- Battery capacity: 5000mAh
- 80W charger (included)
- 6.7 inch OLED display, 1080 x 2412, 120 Hz
- MediaTek Dimensity 7300-Energy
- Tested ROM/RAM combination: 256GB + 12GB
Pros
- Excellent autonomy in cases of indoor use
- Low discharge currents in general
- More than 7 and a half hours of battery life recovered with a 5 minute boost charge
- Full charge completed in just over 53 minutes
Against
- Autonomy slightly lower than average in cases of outdoor use
- Overall charging efficiency less than 75%
- High residual power consumption from the adapter while the device is still connected
The battery of the Oppo Reno12 scored high for its very balanced and impressive performance in terms of battery life, charging and efficiency, signifying a well-optimized system.
The battery life of the device lasted more than 70 hours with moderate use. The device remained strong in indoor testing, losing only about 1% of power per night. In specific use case tests, the battery life of the device was above average, except when listening to music. The battery life of the device was generally good on the move, except during calls, which showed below average battery life.
The Oppo Reno12 features a 5000mAh battery and comes with an 80W charger, which fully charges the device in 53 minutes, faster than average. The powerful charger also helped the device regain an average of more than seven and a half hours of battery life on a 5-minute charge.
Efficiency was also above average due to its exhaust efficiency. The overall charging efficiency of the device on a full charge was less than 75%, meaning that more than a quarter of the energy was wasted during the charging process. However, the Reno12’s discharge currents were lower than average, except when listening to music and when the device was idle with the screen turned off.
Compared to other devices in the high-end segment ($400 to $599), the Oppo Reno12 ranked among the best devices, thanks to its very balanced battery performance.
Test summary
Information on SBMARK battery tests: For scoring 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 battery life score is made up of three performance subscores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes the results of a full range of tests to measure battery life in all types of real-life scenarios.
100 hours
Light usage
Active: 2h30/day
70 hours
Moderate use
Active: 4 hours a day
44 hours
Intense use
Active: 7 hours a day
Home office
A robot housed in a Faraday cage performs a series of touch-based user actions during what we call our “Typical Usage Scenario” (TUS) (making calls, streaming video, etc.) – 4 hours of active use over the course of 16 hours. -a period of one hour, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device runs out of power.

Using a smartphone on the move puts a strain on battery life due to additional “hidden” needs, such as the continuous signaling associated with cellular network selection. SBMARK Battery experts take the phone outdoors and perform a series of well-defined activities following the same three-hour travel itinerary (walking, taking the bus, subway…) for each device
Calibrated

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

How the charging score is made up
Charging is a full part of the overall battery experience. In some situations where battery life is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score is made up of two sub-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 the battery takes to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and until actually fully charged.
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 time to full charge table breaks down the time needed to reach 80%, 100%, and full charge.

With the phone at different charge levels (20%, 40%, 60%, 80%), the Quick Boost tests measure how much charge the battery receives after being plugged in for 5 minutes. The graph here compares the average battery life gain with a 5 minute fast charge.

How the efficiency score is composed
The SBMARK Energy Efficiency Score is composed of two sub-scores, charging speed and discharging speed, which combine both data obtained during a typical robot-based usage scenario, calibrated tests and charging evaluation, taking into account 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 a charge and when in use.

The charging subscore is a combination of four factors: the overall efficiency of a full charge, related to the amount of energy needed to fill the battery compared to the energy 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 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 subscore evaluates how quickly a battery discharges during a test, which is independent of the battery’s capacity. It is the ratio between the capacity of a battery divided by its autonomy. A small capacity battery may have the same battery life as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
