We subjected the Oppo A77 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: 5000mAh
- 33W charger (included)
- 6.56-inch, 720 x 1612, 90Hz LCD display
- MediaTek 810 size (6 nm)
- ROM / RAM combination tested: 64GB + 4GB
Pros
- Exceptional performance during a typical use scenario
- Very low consumption during downtime
- Excellent performance on the go, especially when scrolling through social apps and using the camera
- Excellent autonomy when calling in calibrated mode
- Fair autonomy when streaming music and videos
- Low discharge currents in almost all use cases
versus
- Longer than average charging time
- High discharge current while playing
The Oppo A77 5G showed very well balanced performance in the battery protocol, earning it one of the top three positions in the SBMARK battery database. Its very good results were due to an exceptional autonomy shown during the test in factory default mode. Its performance in a typical usage scenario was among the best we have tested so far, with very low power consumption during the day and excellent handling during the night (1.25% loss on average). The Oppo A77 5G also showed excellent autonomy during tests on the move, especially when scrolling through the social apps (which were the best autonomy tested to date), taking photos and videos and using GPS navigation. However, when tested in calibrated mode, its battery life in tests was close to average, but it did not match the very good results in factory default mode. The device does not appear to be optimized for a brightness level of 200 nits. The on-call time, however, was exceptional, and much better than in on-the-go tests, where the device seemed to have more difficulty finding and reaching the antennas.
The 33W charger took 1 hour and 33 minutes to fully charge the large 5000mAh battery, which is slightly longer than the average charge time in our database. However, a 5-minute charge gave the device more than 5 hours of battery life on average. Performance was average in terms of charging and adapter efficiency, as well as remaining charger consumption.
Discharge currents were low in all use cases, especially during the typical use scenario and during the calibrated mode call test (the lowest discharge current to date). However, the gaming test consumed a lot of power, indicating that the device is not optimized for playing video games.
Compared to other devices in the Advanced segment ($ 200 to $ 399), the well-balanced Oppo A77 5G ranks at the top. It has excellent autonomy and efficiency and decent charging performance. Its battery life while gaming, streaming music and making calls on the go, however, remains below average.
Test summary
About 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.

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 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

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.
