The Oppo F31 Pro+ is officially confirmed to feature the Snapdragon 7 Gen 3 chip. It offers up to 12GB of RAM, 12GB of virtual RAM, UFS 3.1 storage, and a vapour chamber measuring 5,219 mm², significantly larger than its predecessor for better thermal control.
The F31 Pro will run on the Dimensity 7300-Energy, with a 4,363 mm² vapor chamber and graphite sheets for heat dissipation. The standard F31 will feature the Dimensity 6300 SoC and a 4,300 mm² vapor chamber, which improves cooling efficiency by 21 percent over the earlier model.
For photography, the F31 Pro+ and Pro will feature a 50-megapixel main sensor with OIS and a 32-megapixel front camera, while the F31 will offer a 50-megapixel main lens with a 16-megapixel front sensor. The series also supports 4K video recording, AI-enhanced portraits and underwater photography up to 1.5 metres for 30 minutes, backed by IP68 water resistance.
All three phones are equipped with a 7,000mAh battery and support 80W SuperVOOC charging, providing 58 percent charge in half an hour. The F31 series will feature AI-driven tools such as VoiceScribe for transcription and translation, Call Assistant for real-time bilingual support, and AI Notes for editing and restructuring text. In addition, OPPO Docs will provide translation and summarisation tools, while Outdoor Mode 2.0 will cater to delivery workers with enhanced readability and network priority for essential apps.
Durability and smoothness
To handle India’s summer temperatures, the F31 series is built to perform smoothly at up to 43°C and adopts an adaptive heat strategy that raises the throttling threshold to 44–45°C. The lineup is also rated IP69, IP68 and IP66, offering protection against dust, drops and water, including resistance for up to 1.5 metres underwater. In addition, the devices have received an A+ certification from SGS for High-Temperature Fluency, confirming responsive touch, steady frame rates and fluid animations under heavy workloads.
