Ahead of the launch, Oppo has revealed some of the phone’s key highlights, including its massive battery, fast charging, and design.
Large Battery with 80W Fast Charging
The Oppo F31 5G will feature a 7000mAh battery—one of the largest in its segment. Paired with 80W SuperVOOC fast charging, the phone promises long-lasting endurance and quick top-ups, making it ideal for heavy users and gamers.
Design Inspired by Oppo Find X8
Oppo has teased the design of the F31 5G, and it resembles the flagship Oppo Find X8. It features a circular rear camera module, flat sides, and a sleek flat-back finish. Two colour options have been confirmed:
