Oppo K15 offers more RAM, storage and a larger battery than F31 5G, with 12 GB of RAM versus 8 GB, 256 GB of storage versus 128 GB, and a 8000 mAh battery versus 7000 mAh. It also adds a higher-resolution front camera (50 MP versus 16 MP), optical image stabilization on the main camera, and an ultrawide rear camera. OPPO F31 5G, however, is around $142 cheaper and lighter at 185 g versus 205 g and has higher quoted peak brightness at 1400 nits versus 1200 nits. The main trade-off is the K15’s extra RAM, storage, battery capacity, and OIS-equipped camera setup versus the F31 5G’s lower price, higher quoted peak brightness, and lighter build.
