We subjected the Oppo A78 5G to our rigorous SBMARK Battery test suite to measure its performance in terms of range, charging and efficiency. In these test results, we’ll analyze how it performed in a variety of tests and several common use cases.

Overview

Key Specifications:

  • Battery Capacity: 5000mAh
  • 33W charger (included)
  • 6.56-inch, 720 x 1612, 90Hz LCD display
  • MediaTek Dimension 700 (7nm)
  • ROM / RAM combination tested: 128GB + 4GB

Pros

  • Very good autonomy, with almost 3 days of autonomy when used moderately
  • Excellent autonomy on the move
  • Low discharge current in almost all use cases

Against

  • Longer than average reload time
  • Inaccurate battery gauge: 93% of actual measured capacity shown as 100% on display
  • High discharge current when watching videos

The Oppo A78 5G battery provided excellent autonomy when tested in the factory default mode. The device lasted almost three days when used moderately, and the on-the-go performance was excellent. When we tested the usage separately, the runtimes were closer to average.
The device showed good results when streaming video on 4G and during idle times. However, battery life when making calls or listening to music was only average compared to the very good results tested in the factory default mode.

Charging the battery to full capacity took 1 hour and 34 minutes, slightly longer than average. A 5-minute quick charge provided 4.5 hours of battery life, just 10 minutes more than the average in our database. Also, when the device indicated 100% battery level, the actual battery capacity was closer to 93%, which could affect the user experience.

Charger efficiency is just below average in our database, but adapter efficiency was slightly above average. The residual consumption of the charger was also average. Discharge currents were low during our typical use case and when streaming video on 4G, meaning the device is well-optimized for these use cases. However, the discharge currents when playing games or watching videos in Wi-Fi or airplane mode were higher than average.

Compared to devices in the same price range ($200 – $399), the Oppo A78 5G ranked above average in our database. It showed excellent runtimes in the factory default mode, but the recharge and efficiency scores were just below average.

How the Autonomy score is composed

The Battery Life Score is composed of three performance sub-scores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes results from a full range of tests to measure range in all kinds of real-life scenarios.

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 a 16 hour period, plus 8 hours of “sleep”. The robot repeats this series of actions every day until the device runs out.

Using a smartphone on the go has a negative impact on range due to additional “hidden” demands, such as continuous signaling associated with cellular network selection. SBMARK Battery experts take the phone outdoors and perform a series of precisely defined activities 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 to ours bots repeatedly perform actions related to a specific use case (like gaming, video streaming, etc.) at a time. Starting with an 80% charge, all devices are tested until they have used at least 5% battery power.

How the recharge score is composed

Charging is fully part of the overall battery experience. In some situations where range is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Charging Score consists of two subscores, (1) Full Charge and (2) Fast Boost.

The full charge tests evaluate the reliability of the battery charge indicator; measure how long and how much energy it takes for the battery to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and to an actual full charge.

The charging curves, in wired and wireless mode (if available) showing 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 graph breaks down the time required 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 range gain with a 5-minute quick charge.

How the efficiency score is composed

The SBMARK Energy Efficiency Score consists of two subscores, charge rate and discharge rate, which combine both data obtained during a typical robot-based usage scenario, calibrated testing and charge rating, taking into consideration battery capacity of the device. SBMARK calculates the product’s annual energy consumption, shown in the graph below, which is representative of overall efficiency during a charge and when in use.

Charge Up

The secondary charge score is a combination of four factors: the overall efficiency of a full charge, relating to the amount of energy required to recharge the battery compared to the energy the battery can supply; the efficiency of the travel adapter when it comes to transferring power from an outlet to your phone; the remaining 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 sub-discharge score evaluates how quickly a battery discharges during a test, which is independent of battery capacity. It is the ratio between the capacity of a battery and its autonomy. A small capacity battery may have the same run time as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
