Big Battery and Fast Charging

The Oppo F31 comes with a massive 7,000 mAh battery and 80 W SUPERVOOC Flash Charge technology. This combination means users can go longer between charges and still refill the battery quickly when needed. In day-to-day Indian conditions, such a battery size helps heavy users stay online without constantly searching for power outlets.

Durable “Armour Body” Design

Unlike many mid-range phones, the Oppo F31 family features an Armour Body with aerospace-grade aluminium and reinforced glass. It also carries IP66, IP68 and IP69 protection ratings for dust and water resistance. This makes the device a rare rugged option at this price level, ideal for people who travel, work outdoors, or simply want a tougher phone.

Performance and Display

Inside, the base Oppo F31 is powered by a MediaTek Dimensity 6300 chip paired with 8 GB RAM (expandable virtually). The display is a 6.5-inch AMOLED panel with a smooth 120 Hz refresh rate, delivering bright colours and fluid scrolling. These specs are strong enough for streaming, multitasking and light gaming without lag.

Cameras With OIS

Photography is another highlight. The Oppo F31 sports a 50 MP main camera with Optical Image Stabilisation (OIS) and secondary portrait/AI lenses. Selfies are handled by a high-resolution front camera, producing sharp images even in low light. For social media content creators, this setup provides dependable shots without needing a DSLR.

Price and Variants

The Oppo F31 5G starts at ₹22,999 for the 8 GB + 128 GB version, with a larger 256 GB model priced at ₹24,999. Two higher-end variants, Oppo F31 Pro 5G and Oppo F31 Pro+ 5G, come with faster chips and larger displays but cross the ₹25,000 mark.

Comparison in the Segment

At this price, the Oppo F31 competes with devices from Realme, Samsung, and Xiaomi. Its combination of a huge battery, rugged body and OIS camera gives it an edge over typical slim mid-range phones. While it may not match flagship gaming performance, it strikes an excellent balance between endurance, build quality and everyday speed.

Availability and Where to Buy

The Oppo F31 will be available from late September on OPPO’s official website, Flipkart, Amazon and authorised retail stores across India. Early buyers can look for launch offers and exchange deals on these platforms.

Bottom Line

If you’re searching for a powerful yet tough smartphone under ₹25,000, the Oppo F31 makes a compelling case.

With the Oppo F31, OPPO is clearly trying to blur the line between rugged and stylish mid-range phones. Its aluminium frame and glass finish give a premium feel while still maintaining durability. Early reviewers have highlighted the phone’s surprisingly clear stereo speakers and stable 5G reception, which adds value for commuters and travellers.
