Oppo F31 Pro +, F31 Pro, and F31: Performance and thermal design
The F31 Pro+ is powered by Qualcomm’s Snapdragon 7 Gen 3. It uses an octa-core Kryo CPU with a 2.63GHz Cortex-A715 Prime core, three 2.4GHz Cortex-A715 performance cores and four 1.8GHz Cortex-A510 efficiency cores, manufactured on TSMC’s 4 nm process. The phone supports up to 24 GB RAM (12 GB physical + 12 GB virtual) and UFS 3.1 storage. A 5,219 mm² vapour chamber—856 mm² larger than the previous generation—increases thermal dissipation on both sides of the device and slows down heat build-up during sustained workloads.

The F31 Pro runs on MediaTek’s 4nm Dimensity 7300-Energy, an octa-core processor with four 2.5GHz Cortex-A78 cores and four efficiency Cortex-A55 cores. It packs the Mali-G615 MC2 GPU, up to 24GB RAM and UFS 3.1 storage. A 4,363 mm² vapour chamber and expanded graphite sheets improve heat dissipation during long sessions.
The F31 runs the 6nm Dimensity 6300 SoC with two 2.4GHz Cortex-A76 cores and six 2GHz Cortex-A55 cores, paired with the Mali-G57 MC2 GPU. It uses a 4,300 mm² vapour chamber with extended graphite coverage that improves thermal efficiency by 21% over the previous generation.
Oppo F31 Pro +, F31 Pro, and F31: Software
All three phones run ColorOS 15 with OPPO’s Dual-Engine Smoothness System that combines the Trinity Engine and the Luminous Rendering Engine.
