What I would choose
I would choose the Xiaomi Poco C40. The larger battery capacity is a significant advantage for my personal use case, as I often find myself away from a charger for extended periods. While the Oppo A15 is lighter and has a more versatile camera system, the performance boost and significantly improved battery life of the Poco C40 outweigh these factors for me. Additionally, the faster charging is a nice bonus. Even though the camera might be slightly better on the Oppo A15 due to the extra macro lens, I do not use this type of camera very often making it not as useful.
