Durability and Build Quality
The highlight of the Oppo F31 series is its durability. Unlike many other smartphones in its category, the F31 series comes with IP66, IP68, and IP69 ratings. This makes the phones resistant to dust, splashes, and even underwater submersion.

In addition, Oppo is including 80W fast charging, allowing users to recharge quickly and reduce downtime. For gamers, streamers, and professionals who rely heavily on their devices, this will be a major selling point.
