  • Cameras: 50MP OIS rear + 16MP selfie.

  • Price: Starts at ₹22,999 (Amazon, Flipkart, Oppo India).



OPPO F31 Series 5G Display & Design: Built to Withstand Everything

The Oppo F31 5G Mobile Phone features a 6.57-inch flat AMOLED screen with 120Hz refresh rate for smooth scrolling and gaming. The F31 Pro+ ups the size to 6.8 inches, targeting binge-watchers and gamers. What makes the series stand out is Oppo’s 360° Armour Body, making it the first in its segment to sport IP66, IP68, and IP69 certifications. Whether it’s dust, water, or accidental drops, the F31 is designed to handle it.



OPPO F31 Series 5G Performance & Processors: Choice for Every User

Oppo has positioned the F31 lineup smartly:

  • Oppo F31 5G: MediaTek Dimensity 6300, ideal for students and casual gamers.

  • Oppo F31 Pro 5G: Dimensity 7300-Energy, efficient for creators and multi-taskers.

  • Oppo F31 Pro+ 5G: Snapdragon 7 Gen 3 + up to 12GB RAM, tuned for gamers and power users.


All models ship with Android 15 + ColorOS 15, ensuring new features like AI wallpapers, enhanced app security, and smoother multitasking.



OPPO F31 Series 5G Camera Setup: AI Meets Stability

Photography remains central to Oppo’s identity. The F31 carries a 50MP OIS main sensor + 2MP monochrome camera. OIS (Optical Image Stabilization) means sharper low-light shots, while AI-powered HDR enhances daylight portraits. The 16MP selfie camera is optimized for Instagram Reels and video calls. Pro+ adds advanced computational photography for ultra-clear night portraits.



OPPO F31 Series 5G Battery & Charging: Power for Two Days

The real headline feature is the massive 7,000mAh battery, the biggest in its class. With 80W SUPERVOOC fast charging, users can charge 50% in under 30 minutes. For India’s heavy smartphone users — from travelers to OTT binge-watchers — this is a serious differentiator. Oppo’s AI charging also prevents overheating and prolongs battery health.



OPPO F31 Series 5G Price & Availability in India

Oppo has priced the F31 Series aggressively to attract India’s mid-range buyers:

  • Oppo F31 5G (8GB+128GB): ₹22,999

  • Oppo F31 5G (8GB+256GB): ₹24,999

  • Pro & Pro+ pricing starts higher, with Flipkart and Amazon festival offers expected soon.

OPPO F31 Series 5G Expert Take

Tech reviewers note that the triple IP rating is a rare feature in sub-₹25K phones. Combined with a huge battery and AMOLED display, Oppo is betting big on durability + endurance as its USP. This is a direct challenge to Samsung M-series and Realme GT-series in India.


USP Box: Why OPPO F31 Stands Out

  • 7,000mAh battery + 80W charging → 2-day use

  • Triple IP-certified durability → first in segment

  • Pro+ with Snapdragon 7 Gen 3 → premium gaming
