In the cutthroat mid-range smartphone segment, OPPO is again making a solid argument with its new addition—the OPPO F31 Pro+ 5G. Available in India since September 15, 2025, the OPPO F31 Pro Plus 5G packs dependable performance, a rugged build, and great battery life to become a desirable option for tech users and casual consumers alike. Regardless of whether you are looking for a gaming, photography, or productivity smartphone, the F31 Pro+ promises to provide an all-around experience at an affordable price.
Design and Build Quality
The OPPO F31 Pro+ has a strong and tough build. It boasts a 360° Armour Body design, making it as tough as nails. It boasts IP66/IP68/IP69 water- and dust-proof ratings, so you don’t have to worry about it getting ruined from spills, dust, or even immersion in liquid. To boot, it complies with the MIL-STD-810H military standard, so you can trust that it can go through rough treatment.
The design of the phone does not compromise on looks either. It is available in a classy Gemstone Blue color, which gives it a solid and sleek appearance. With its rugged build, it still remains comfortable to grip, courtesy of design elements with ergonomics in mind. The weight and size are perfectly balanced so that it fits well in the hand for single-handed use, even though the massive display is inclined more towards two-handed use for optimal usability.
Display: Big, Bright, and Smooth
At the center of the OPPO F31 Pro+ is a 6.79-inch AMOLED screen measuring 2772 × 1240 pixels in resolution and 120Hz in refresh rate. The AMOLED display provides rich blacks and vivid colors, thereby making media consumption enjoyable. Whether watching high-definition videos or gaming with graphics-demanding games, the seamless refresh rate assists in providing a touch-sensitive and silky smooth visual experience.
The screen’s size is ideal for heavy media users or multitaskers, and the high-resolution screen guarantees crispness in every aspect. The screen is guarded by Corning Gorilla Glass, which provides a further level of scratch and minor impact resilience.
Performance: Speed That Keeps Up
Powering the OPPO F31 Pro+ is the latest Qualcomm Snapdragon 7 Gen 3 processor. Coupled with 8GB or 12GB of RAM, the chipset offers seamless performance for everyday tasks, gaming, and multitasking. Whether you’re switching between apps, editing photos, or enjoying a demanding mobile game, the F31 Pro+ handles it all with ease.
The smartphone operates on Android 15 with ColorOS 15, with a clean and customizable interface. OPPO’s ColorOS is famous for its user-centric philosophy, filled with practical features and silky-smooth animations that enhance the user experience. You should look forward to regular updates and optimizations to ensure the system remains in top condition.
Camera: Take Life in Beautiful Detail
The highlight of the F31 Pro+ is photography with a 50MP main rear camera (OV50D40 sensor) joined by a 2MP monochrome sensor. The key differentiator is that it comes with 2-axis Optical Image Stabilization (OIS) that assists in taking clear images even when the device is held shakily. Whether you are snapping in broad daylight or dark environs, the camera delivers clean and clear images.
For selfies and video chats, the 32MP selfie camera performs very well at taking clear and colorful photos. There are many modes available in the camera app, such as portrait, night mode, and recording at 4K resolution. Videographers will love the stable video recording and the variety of recording modes.
Battery Life: All-Day Power
The most striking aspect of the OPPO F31 Pro+ is its 7000 mAh battery, which is enormous in size. This huge capacity guarantees that the phone will see several days of heavy use or even a week without needing to be recharged. For heavy users who have multiple applications running, stream media, or play games, this phone offers the stamina to survive without being constantly charged.
Additionally, OPPO features 80W SUPERVOOC fast charging, which can charge the battery up to 50% in 15-20 minutes. This translates to less downtime and more usage, which is particularly convenient in this day and age.
Durability: Built to Last
In contrast to most smartphones in its price class, the OPPO F31 Pro+ is serious about durability. Its IP68/IP69 water and dust resistance certifications give assurance against the mishaps of day-to-day life. Be caught in the rain or drop the phone on the edge of a sink, the F31 Pro+ is built to last.
The military-grade certification also serves to highlight its ruggedness, so this is a great option for those who work outdoors or those who just like to experience the odd mishap.
Storage Options
Storage is bountiful on the OPPO F31 Pro+, with 256GB of built-in storage found on both the 8GB and 12GB RAM variants. This generous storage capability guarantees you enough room to store all your photos, videos, apps, and documents without bothering to delete anything just because of a lack of space. Unfortunately, the phone has no support for expandable storage through microSD cards, which means choosing the correct variant in the first place is crucial.
Pricing and Availability
The OPPO F31 Pro+ is reasonably priced in India:
- 8GB RAM + 256GB Storage: ₹32,999
- 12GB RAM + 256GB Storage: ₹34,999
It can be bought from major stores like Amazon India, Croma, and the official OPPO India Store.
Final Verdict: Is the OPPO F31 Pro Plus 5G Worth It?
For a 2025 mid-range smartphone, the OPPO F31 Pro+ finds a great balance between camera, battery life, and build quality. Its tough construction, big AMOLED screen, effective camera setup, and massive battery make it very appealing for those looking for more than the bare minimum.
If you are a battery-life enthusiast, frequent traveler, casual rough handler, and fair photography performer, the OPPO F31 Pro+ is likely to find a place on your priority list. It is a dependable all-rounder with enough stamina to perform both work and play without any compromise.
