My Choice
I would choose the Oppo A15.
While the larger battery and faster charging of the Samsung Galaxy A02s are appealing, the significantly better performance of the Oppo A15, combined with its more versatile camera, superior screen protection, additional sensors, and newer Bluetooth version, make it the more compelling option for my typical usage. The fingerprint sensor provides a convenient security feature, and the potential for better Wi-Fi connectivity is a bonus. I am usually around a power source, so the slightly smaller battery would not affect me as much.
