OPPO F31 series: Details

OPPO said that every F31 model will be available in multiple finishes and sizes, weighing between 187g and 204g and measuring 7.7–7.96mm in thickness. The Pro Plus variant will feature a 6.8-inch AMOLED screen, while the F31 Pro and standard F31 will include 6.57-inch AMOLED displays, all with screen-to-body ratios above 93 per cent. Buyers will get a wide colour palette to choose from, including Gemstone Blue, Himalayan White, Festival Pink, Desert Gold, Space Grey, Midnight Blue, Cloud Green, and Bloom Red.

 

The series will bring a 7,000mAh battery that supports 80W SuperVOOC fast charging, along with reverse and bypass charging options. According to OPPO, the battery is engineered for longevity, using self-repairing electrolyte tech that allows up to 1,830 charge cycles while retaining about 80 per cent of capacity after five years. 

 

OPPO is emphasising the ruggedness of the F31 series with several protective measures. The phones are certified with three IP ratings — IP66 against dust and splashes, IP68 for immersion in up to 1.5 metres of water, and IP69 for withstanding strong water jets. OPPO also claims the devices have been exposed to eighteen different liquids, such as coffee, soft drinks, and soap water, as part of testing. To further ensure reliability, the series integrates water-resistant microphones, reinforced SIM card trays, and a drainage channel for speakers.

 

  For durability against drops, OPPO says the F31 range adopts a 360-degree Armour Body structure that has cleared seven MIL-STD-810H tests. These include endurance against shock, dust, sand, and extreme temperatures. The devices are said to survive falls from as high as 1.8 metres, supported by features like shock-dampening pads around vital hardware, foam cushions for internal parts, reinforced edges, and slightly raised camera modules. The chassis uses aerospace-grade aluminium alloy, and the display is protected by AGC DT-Star D Plus glass.
