Build: Oppo is boasting about a "360-degree damage-proof Armour Body". This, combined with the top-tier IP69 + IP68 + IP66 ratings, means these phones are built to last. They are resistant to dust, water jets, and even temporary immersion in water. This makes them great for clumsy users or those with an active lifestyle.
Display: The standard and Pro models have a 6.5-inch AMOLED display, which promises vibrant colors and deep blacks. The Pro model gets an advantage with an adaptive refresh rate (60Hz/90Hz/120Hz), which helps save battery life by adjusting the screen smoothness based on what you're doing. The Pro+ model has the largest and sharpest screen at 6.8 inches with a higher pixel density.
5. Performance Analysis: Which Chipset is Best for You?
This is where the three models differ significantly.
Oppo F31 5G (Dimensity 6300): This is a capable processor for everyday tasks like social media, calls, messaging, and casual gaming. It handles 5G well and is efficient, which is perfect for maximizing that huge battery.
Oppo F31 Pro 5G (Dimensity 7300 Energy): The "Energy" in its name highlights its focus on efficiency. It is noticeably more powerful than the Dimensity 6300, especially for multitasking and more intensive games like BGMI or Call of Duty Mobile at medium to high settings.
Oppo F31 Pro+ 5G (Snapdragon 7 Gen 3): This is the most powerful chipset in the series. Qualcomm's Snapdragon 7 series is known for offering flagship-like performance without the high cost. It will deliver the best gaming experience, the fastest app launches, and smooth performance for years to come.
Verdict: For most users, the Dimensity 7300 in the Pro model offers the best balance of price and performance. Hardcore gamers and power users should consider the Pro+ for the Snapdragon chip.
6. The Main Attraction: Camera Review (50MP with OIS)
Oppo has focused on a simple but powerful dual-camera setup on all models: a 50MP primary sensor with OIS and a 2MP depth sensor for portrait shots.
Why OIS is a Big Deal? OIS (Optical Image Stabilization) is a hardware feature that physically stabilizes the camera lens. This results in:
Sharper low-light photos: The camera can let in more light without blur from hand shake.
Stable videos: Videos look smooth and professional, not shaky.
This is a significant advantage over many competitors in this price range that skip OIS.
What to Expect: In good light, the 50MP sensor should capture detailed and vibrant photos. The front 16MP camera is standard for selfies and video calls. The cameras also support fun features like multi-view video, underwater mode (thanks to the IP rating), and up to 10x digital zoom.
7. The Game-Changer: 7000mAh Battery and 80W Charging
This is the headline feature, and for good reason. A 7000mAh battery is enormous.
Expected Battery Life: Based on this capacity, you can easily expect:
1.5 to 2 days of heavy use (gaming, videos, GPS).
Up to 3 days of moderate use (calls, messages, some social media).
Weeks of standby time.
Blazing-Fast Charging: The 80W SuperVOOC charging is incredibly fast. It can charge this massive battery from 0 to 50% in roughly 20-25 minutes. A full charge should take just over an hour, which is mind-blowing for a battery this size. You will never have to worry about battery anxiety again.
8. Pros and Cons Summary
Pros:
Unbeatable battery life with 7000mAh capacity.
Extremely fast 80W charging.
Strong, durable build with high IP ratings.
Good primary 50MP camera with OIS (a key advantage).
Clean software with Android 15-based ColorOS 15.
Cons:
No ultra-wide camera: The 2MP depth sensor feels outdated; an ultra-wide lens would have been more useful.
Slightly heavy: Due to the big battery, the phones are heavier than average.
Competitive market: Faces tough competition from brands like Nothing, Samsung, and Realme.
