OPPO F31 5G Series Launched In India: Durable Design, 7,000mAh Battery, And Advanced AI Camera

The biggest concern for Indian smartphone users today is durability. According to a report by Counterpoint Research, 79% of buyers prioritize a durable phone over other features. Keeping this in mind, OPPO India has launched the F31 5G Series, which includes three models – F31 Pro+, F31 Pro, and F31.

The company claims this series is India’s most durable and smooth-performing smartphone range under ₹35,000. The phones feature a 360° Armor Body, aerospace-grade aluminum alloy frame, and AGC DT-Star D+ glass protection. Adding to this, the devices are rated IP66, IP68, and IP69, making them resistant to dust, water, and even high-pressure jets.

Advanced Cooling to Prevent Overheating

Overheating is a common issue during Indian summers. OPPO has addressed this with dedicated vapour chambers:
