Oppo is preparing to expand its popular F-series lineup with three new devices the Oppo F31, Oppo F31 Pro, and Oppo F31 Pro+. Recently leaked promotional images and early specifications have revealed significant upgrades, especially in terms of battery capacity and charging speeds. Interestingly, while all three models belong to the same family, they adopt very different design approaches, signaling Oppo’s intent to give each device a distinct identity.
Here’s a complete breakdown of what we know so far about the upcoming Oppo F31 trio, based on the leaks and industry reports.
Distinctive Design for Each Model
Unlike the F29 series, where models shared a similar look, the F31 lineup introduces clear design differences across its three variants:
Oppo F31 Pro+
The F31 Pro+ takes the premium spot in the lineup. According to the leaked renders, it features a flat display and a circular rear camera island, a style reminiscent of the Oppo F29 Pro launched earlier this year. The device will reportedly be offered in elegant shades such as white, pink, and blue.
Oppo F31 Pro
The F31 Pro is designed with a more balanced appeal. Its camera housing has a squircle (rounded square) shape, setting it apart from both the vanilla and Pro+ models. Leaked renders showcase finishes in black and gold, giving it a more classic look compared to the vibrant color palette of the base model.
Oppo F31 (Standard)
The standard F31 comes with a pill-shaped vertically stacked camera module placed inside a rectangular frame. This version is expected to target younger buyers, given its bold and vibrant colors such as red, purple, and blue.
