Paired with 80W SuperVOOC fast charging, the phones can reach 50% in about 25 minutes and a full charge in under an hour.
This battery prowess addresses a common pain point in India, where fluctuating 4G/5G networks can drain power quickly. Whether you’re streaming, gaming, or working on the go, the Oppo F31 5G series keeps you powered up without the need for a power bank.
Camera Capabilities: Capture Every Moment
Photography enthusiasts will appreciate the Oppo F31 5G series camera setups. All models feature a 50MP primary rear sensor paired with a 2MP depth sensor, delivering sharp, vibrant photos in various lighting conditions.

Features like Portrait mode, Super Night mode, and 2K video recording add versatility, making the Oppo F31 5G series a solid choice for social media enthusiasts and casual photographers. The circular camera module, a design highlight, adds a premium touch to the overall look.

Why the Oppo F31 5G Series Stands Out
The Oppo F31 5G series is more than just a smartphone lineup—it’s a bold step toward redefining the mid-range segment. Here’s why it matters:
Unmatched Durability
With IP66, IP68, and IP69 ratings and a 360-degree Armor Body, the Oppo F31 5G series is built to withstand India’s toughest conditions, from monsoons to dusty roads. This durability sets it apart from competitors like the Realme 15T or Vivo T4 5G, which often lack such robust ratings.
Massive Battery Life
The 7,000mAh battery is a game-changer, offering unmatched endurance for heavy users. Combined with 80W fast charging, it ensures you’re never tethered to a charger, even during long commutes or gaming sessions.
Affordable Pricing
Starting under ₹20,000, the Oppo F31 5G series delivers flagship-level features like AMOLED displays, 5G connectivity, and durable builds at a fraction of the cost of premium phones like the iPhone 17 or Samsung Galaxy S26.
Stylish Design
The textured rear panel, vibrant colors, and slim profile make the Oppo F31 5G series a head-turner. The circular camera module and flat sides give it a premium feel without the premium price tag.
Competing in India’s Mid-Range Market
The Oppo F31 5G series enters a competitive segment, facing off against brands like Vivo, Realme, and Xiaomi. Here’s how it compares:
vs. Vivo T4 5G
The Vivo T4 5G offers a similar price range (~₹20,000) and AMOLED display, but its battery is smaller (around 5,000mAh). The Oppo F31 5G series’ 7,000mAh battery and IP66/IP68/IP69 ratings give it an edge in durability and endurance.
vs. Realme 15T 5G
The Realme 15T 5G is a strong contender with a 120Hz AMOLED display and fast charging, but its battery (around 5,000mAh) and durability ratings don’t match the Oppo F31 5G series’ robust build and 7,000mAh capacity.
vs. Samsung Galaxy F36 5G
Samsung’s Galaxy F36 5G targets the ₹25,000–₹30,000 range, but its smaller battery and less comprehensive IP ratings make the Oppo F31 Pro 5G and Pro+ 5G more compelling for durability-focused buyers.
Who Should Buy the Oppo F31 5G Series?
The Oppo F31 5G series is ideal for:
- Students: The large battery, durable build, and vibrant AMOLED display make it perfect for studying, gaming, and social media.
- Gamers: The Snapdragon 7 Gen 3 (Pro+) and 120Hz displays ensure smooth gameplay for titles like BGMI or Call of Duty Mobile.
- Budget Buyers: Starting under ₹20,000, it offers premium features like 5G, fast charging, and durability.
- Travelers and Outdoor Enthusiasts: The IP66/IP68/IP69 ratings and 360-degree Armor Body make it ideal for rugged use.
Why the Oppo F31 5G Series is a Game-Changer
The Oppo F31 5G series redefines the mid-range segment with its blend of durability, performance, and style. Its 7,000mAh battery ensures all-day power, while the IP66/IP68/IP69 ratings and 360-degree Armor Body make it one of the toughest phones in its class.
