My Choice
If I had to choose between these two phones, I would pick the Nokia C31. While the Oppo A15 is more compact and includes a compass and gyroscope, the larger battery and newer version of Android on the Nokia C31 are more important to me for daily use. I find that having a phone that can last through a full day without needing to be charged is incredibly valuable, and the more up-to-date software ensures that I am getting the latest features and security updates. Even though the A15 is slightly lighter, I'm willing to accept the extra weight of the C31 in exchange for the longer battery life and other benefits it provides. The higher base storage is also a plus.
