From the OPPO A15 test results, we have given this Smartphone a ViserMark Battery Performance Score of 49. The Battery Performance Label, being lower than 50 indicates that it is one of the mid-performing Smartphones and has been ranked in 34th place of the best Battery Performance Smartphones as tested by SmartViser.

Through the ViserMark test protocol, the OPPO A15 achieved a ViserMark Battery Life score of 2 Days of Use.
The average Day of Use ViserMark score of an Entry -Tier device is “2.2” Days. The OPPO A15 score places the Smartphone 25th in rankings.
Our testing is based on real smartphone usage from 100% battery level down to Power Off. When testing Smartphones, the testing protocol includes common daily life activities, for instance: Calls, Web, Video and Music streaming, Gaming, Social networks, Picture & Video capture and standby.
All testing is performed under strictly controlled test conditions with all activities being executed in a defined order and timeline.
OPPO A15 Test Graphics
There are a number of power-efficient processors, within today's Smartphones, that are able to cope with the growing number of new applications and can support high-resolution displays without compromising battery life.
Power Efficiency is calculated using Battery Life and Battery Capacity. This is expressed in “Leaves" and reflects a rating between 1 being least and 5 being the most power-efficient.
The OPPO A15 achieved an overall Power Efficiency Score of 2, placing the device 21st within the ranking for Power Efficiency.
To conclude, the OPPO A15 performance is good given the battery capacity (4230mAh) and the modest components it uses, its score stands very close to other Entry Tier devices with a similar battery capacity like the Realme C11 with a performance of 50 or the Xiaomi Redmi with a score of 49.
ViserMark tests are performed with the strictest protocol in a controlled environment to ensure repetition and consistency powered and automated by SmartViser’s test automation solution viSer. The automation test includes a variety of user actions from calls to social media and periods of standby times.
