What if your phone could run for days, handle splashes, and still look stylish? That’s exactly what Oppo is promising with the F31 series, set to launch in India on September 15, 2025. With a powerful 7,000mAh battery, strong durability, and fresh designs, the F31, F31 Pro, and F31 Pro+ are ready to shake up the mid-range space. Let’s see what makes them stand out.
Why The Oppo F31 Series Is Grabbing Attention
Oppo is calling the F31 line the “Durable Champion,” and the name fits well. These phones bring together long-lasting battery power, advanced water and dust resistance, and bold designs aimed at buyers who want more than just a basic phone. Priced to stay in the budget-friendly bracket, the series targets gamers, creators, and everyday users who need a device that doesn’t quit.
What’s New In The F31 Series
Here’s what makes the F31 lineup worth a look:
- Massive Battery Life: All three models—F31, F31 Pro, and F31 Pro+—carry a 7,000mAh battery. That’s a step up from the F29’s 6,000–6,500mAh and promises over a full day of heavy usage.
- Fast Charging Support: Both the F31 and F31 Pro come with 80W SuperVOOC fast charging. The Pro+ could be even quicker, making it perfect for people who stay busy.
- Strong Protection: With IP66, IP68, and IP69 ratings, the phones are built to resist dust, water splashes, and even high-pressure jets. Oppo has also added a “360-degree Armor Body” for added toughness.
- Fresh Design Choices:
- F31: Pill-shaped camera, available in blue, green, or red.
- F31 Pro: Squircle-shaped module, in gold or grey.
- F31 Pro+: Circular camera, with white, pink, or blue options.
- Smooth Everyday Use: Running on ColorOS 15 with AI features, the F31 is powered by a Dimensity 6300, the Pro steps up to Dimensity 7300, and the Pro+ runs on Snapdragon 7 Gen 3.
How It Stacks Against Rivals
The F31 series is positioned against Vivo Y500 and Redmi Note 15 in India’s mid-range market. Here’s a quick comparison:
| Feature | Oppo F31 Series | Vivo Y500 | Redmi Note 15 |
|---|---|---|---|
| Starting Price (India) | ₹20,000–₹35,000 | ~₹22,000 | ~₹20,000 |
| Battery | 7,000mAh, 80W charging | 6,000mAh, 66W charging | 5,000mAh, 67W charging |
| Durability | IP66/IP68/IP69 | IP65 | IP54 |
| Display | 6.57″–6.79″ AMOLED, 120Hz | 6.6″ AMOLED, 120Hz | 6.67″ AMOLED, 120Hz |
| Processor | Dimensity 6300–Snapdragon 7 | Dimensity 6020 | Snapdragon 6 Gen 1 |
The F31’s battery capacity and durability clearly give it an advantage, especially for buyers who value long use and reliability over advanced camera setups.
What People Are Saying
On X, users are talking about the 7,000mAh battery and rugged body, both of which suit India’s varied conditions. The ColorOS 15 interface with AI-driven multitasking is also being praised for being smooth and easy. But some are worried about the camera system. The phones are expected to feature a 50MP main + 2MP depth sensor, and a selfie camera that’s 16MP on the F31 and 32MP on the Pro and Pro+. Many feel Oppo could have offered ultrawide or telephoto options instead of relying on a dated depth sensor. Still, the bold colors, especially the Pro+ pink edition, are getting attention from style-focused buyers.
Concerns You Should Know
Some recall that the F29 had an average camera, and they fear the F31 may follow the same path. The 2MP depth sensor looks basic when compared with what rivals offer. But Oppo’s main focus this time is durability and battery life, which are the features most mid-range buyers look for.
Why It Matters
If you dislike charging your phone every night or worry about spills and drops, the F31 series is worth considering. With a price range of ₹20,000–₹35,000, it brings AMOLED displays, strong build, and quick charging at a fair price. Whether you play games, stream videos, or just scroll all day, the F31 promises reliable performance and style.
Launch Details
The Oppo F31 series will launch on September 15, 2025, at 12 pm IST. You can watch the launch live or check Oppo’s official website for pre-booking details. With its mix of durability, battery strength, and modern looks, the F31 series could easily become a daily driver for many.
