Performance, Display, and Camera
The OPPO F31 Pro F31 series splits its processor lineup to cater to different performance needs. The F31 Pro Plus runs on a Qualcomm Snapdragon 7 Gen 3 octa-core chip built on a 4nm process, with clock speeds ranging from 1.8GHz to 2.63GHz and an AnTuTu score of 10,77,869 in testing by 91mobiles. The F31 Pro, on the other hand, uses the MediaTek Dimensity 7300 Energy chipset.
To keep thermals in check during intensive gaming, both phones include a 5219mm² SuperCool VC cooling system along with OPPO's Dual-Engine Fluency technology. The company is promising up to 72 months of lag-free performance.
Display Specifications
The F31 Pro sports a 6.5-inch flat AMOLED panel with 2372×1080 pixel resolution, 120Hz refresh rate, and a peak brightness of 1,400 nits. The F31 Pro Plus steps up to a larger 6.8-inch flat AMOLED display with 2800×1280 resolution and a brighter 1,600 nits output — both screens are well-suited for outdoor use and media consumption.
Camera System
Both the F31 Pro and F31 Pro Plus feature a dual rear camera setup. The primary sensor is a 50-megapixel OIS-enabled shooter with an f/1.8 aperture and LED flash, paired with a 2-megapixel monochrome lens. The camera supports up to 10x zoom. For selfies and video calls, a 32-megapixel front camera is present on both models.
7,000mAh Battery and Military-Grade Build Quality
The standout feature of the entire F31 lineup is its 7,000mAh battery — the first time OPPO has used such a large cell in the F series. Previous flagbearer, the OPPO F29 Pro, topped out at 6,500mAh. To offset the larger battery's charge time, OPPO has included 80W SUPERVOOC fast charging, along with Reverse charging and Bypass charging support on both Pro models.
On the durability front, the F31 Pro and F31 Pro Plus are built around a 360° Armour Body frame and have earned MIL-STD-810H-2022 military-grade certification. The triple IP rating — IP69+IP68+IP66 — means these phones can resist not just water ingress but exposure to 18 different types of liquids, making them among the most rugged offerings in their price segment.
