Introduction OPPO F31 5G Smartphone
Are you looking for a reliable 5G smartphone that does not burn a hole in your pocket? The OPPO F31 5G Phone might be exactly what you need. This phone sits in that sweet spot where you get premium-looking features without paying flagship prices. From its gorgeous AMOLED display to its massive battery, there is a lot to talk about.
In this detailed review, we will break down everything about the OPPO F31 5G Phone. We will cover its design, performance, camera quality, battery life, and much more. By the end, you will know whether this phone deserves your hard-earned money or not.
Let us dive right in.
What Makes OPPO F31 5G Phone Stand Out?
The smartphone market is incredibly crowded right now. Every brand is trying to offer the best specs at the lowest price. So what makes the OPPO F31 5G Phone different from the rest?
Well, OPPO has always been known for building phones that look and feel more expensive than they actually are. The F31 5G continues that tradition. It combines a stunning AMOLED display, a capable processor, a huge battery, and fast charging into a package that costs just ₹25,980. That is a lot of value packed into one device.
The phone also comes with 256 GB of internal storage, which is generous for this price range. You will not have to worry about running out of space anytime soon. Whether you store thousands of photos, dozens of apps, or hours of video content, this phone has room for it all.
Design And Build Quality
A Phone That Looks Premium
The first thing you notice about the OPPO F31 5G Phone is its design. OPPO has done a fantastic job making this phone look elegant. The Cloud Green color variant, in particular, has a soft and refreshing vibe that stands out from the usual black and blue options.
The phone is slim and lightweight, which makes it comfortable to hold for long periods. Whether you are scrolling through social media, watching videos, or texting friends, your hand will not feel tired. The build quality feels solid without being too heavy.

IP64 Dust And Water Resistance
One of the pleasant surprises here is the IP64 rating. This means the OPPO F31 5G Phone offers protection against dust and water splashes. Now, this does not mean you should take it swimming. But if you get caught in light rain or accidentally spill some water on it, your phone should be just fine. At this price point, having any level of water resistance is a welcome addition.
Display Quality
Brilliant AMOLED Screen At 120 Hz
The OPPO F31 5G Phone features a 6.72-inch FHD+ AMOLED display with a smooth 120 Hz refresh rate. Let us break down why this matters.
First, AMOLED displays are known for their vibrant colors, deep blacks, and excellent contrast. When you watch movies, play games, or simply browse photos, everything looks rich and lively on this screen. The colors pop without looking unnatural.
Second, the 120 Hz refresh rate makes everything feel incredibly smooth. Scrolling through Instagram, swiping between apps, and navigating menus all feel buttery and responsive. Once you experience 120 Hz, going back to a standard 60 Hz display feels sluggish.
The FHD+ resolution ensures that text is sharp and images are crisp. Whether you are reading articles or watching YouTube videos, the display delivers a great viewing experience.
Performance And Processing Power
MediaTek Dimensity 6300 Chipset
Under the hood, the OPPO F31 5G Phone runs on the MediaTek Dimensity 6300 processor. This is a 5G-capable chipset designed for mid-range smartphones. It handles everyday tasks with ease. Opening apps, switching between multiple tabs, and running social media platforms all work smoothly without any noticeable lag.
The phone comes with 8 GB of RAM, which is more than enough for most users. OPPO also includes a virtual RAM expansion feature, which uses a portion of the storage as additional RAM when needed. This helps when you have many apps running in the background.

Is It Good For Gaming?
Here is where you need to set realistic expectations. The Dimensity 6300 is a solid processor for daily use and casual gaming. Games like Candy Crush, Subway Surfers, and even BGMI on medium settings run well. However, if you are a hardcore gamer who wants to play graphics-heavy titles at maximum settings, this chipset may struggle a bit.
For the average user who games casually, the OPPO F31 5G Phone will not disappoint. Just do not expect flagship-level gaming performance at this price.
Camera Performance
Rear Camera Setup
The OPPO F31 5G Phone features a dual rear camera system. The primary sensor is a 50 MP main camera, and it is paired with a 2 MP depth sensor.
The 50 MP main camera captures detailed and well-balanced photos in good lighting conditions. Daytime shots come out sharp with accurate colors. The HDR processing does a decent job of balancing highlights and shadows, so your photos look natural.
Portrait mode works reasonably well thanks to the depth sensor. The background blur looks smooth and the edge detection around the subject is fairly accurate. However, do not expect the same level of precision you would get from a flagship phone.
Low-light photography is acceptable but not exceptional. The phone does its best to brighten up dark scenes, but you will notice some noise and loss of detail in very dim conditions. If night photography is a top priority for you, there are better options available at a slightly higher price.
What About The Ultrawide And Macro?
This is one area where the OPPO F31 5G Phone falls short. There is no ultrawide lens or dedicated macro camera. If you enjoy taking wide-angle landscape shots or extreme close-ups of tiny objects, you will miss having those extra lenses. At this price, some competitors do offer triple camera setups with ultrawide options.
Front Camera For Selfies
The 16 MP front camera handles selfies and video calls well. Skin tones look natural, and there is enough detail in the photos. OPPO includes beauty mode and various filters for those who like to enhance their selfies. Video calls on WhatsApp and Zoom look clear and smooth.
Battery Life And Charging
A Massive 7000mAh Battery
One of the strongest selling points of the OPPO F31 5G Phone is its 7,000mAh battery. This is a large battery that comfortably gets you through a full day of heavy usage. If you are a moderate user, you can easily stretch it to a day and a half or even two days.
Streaming videos, browsing the internet, using social media, and making calls throughout the day will still leave you with battery to spare by bedtime. This kind of endurance is incredibly reassuring, especially if you are always on the go and do not have time to charge your phone frequently.
45W SUPERVOOC Fast Charging
When you do need to charge, the 80W SUPERVOOC fast charging gets the job done quickly. You can go from zero to a significant percentage in just about 30 minutes. A full charge does not take very long either. This combination of a big battery and fast charging is one of the best features of the OPPO F31 5G Phone.
No more anxiety about your phone dying in the middle of the day. Charge it quickly in the morning, and you are good to go.
Software Experience
Android 15 with ColorOS 15
The OPPO F31 5G Phone runs Android 15 with OPPO's custom ColorOS 15 skin on top. ColorOS has improved significantly over the years. It is clean, well-organized, and packed with useful features.
You get a smooth and intuitive user interface that is easy to navigate. The notification panel, settings menu, and app drawer are all logically arranged. OPPO also includes useful customization options, allowing you to personalize themes, icon styles, and always-on display designs.
One thing to keep in mind is that ColorOS does come with some pre-installed apps. While most of them can be uninstalled, it might slightly bother users who prefer a completely clean software experience.
Connectivity Features
Dual-SIM 5G Support
As the name suggests, the OPPO F31 5G Phone supports dual-SIM 5G connectivity. This means both your SIM cards can access 5G networks where available. As 5G coverage continues to expand across India, having a future-ready phone makes a lot of sense.
Apart from 5G, you also get standard connectivity options like Wi-Fi, Bluetooth, GPS, and a USB Type-C port for charging and data transfer. The in-display fingerprint sensor is fast and accurate, unlocking your phone almost instantly.
OPPO F31 5G Phone vs Competitors
At around ₹25,980, the OPPO F31 5G Phone competes with several strong alternatives. Let us see how it holds up against some popular rivals.
OPPO F31 5G vs Galaxy A35 5G
The Samsung Galaxy A35 5G offers a slightly smaller 6.6-inch AMOLED display with 120 Hz refresh rate. It runs on the Exynos 1380 processor and packs a 5,000 mAh battery with only 25W charging. When compared to the OPPO F31 5G Phone, Samsung falls behind in battery size and charging speed. However, Samsung generally offers longer software update support which is worth considering.
OPPO F31 5G vs Vivo T3 5G
The Vivo T3 5G is another strong competitor. It features a 6.67-inch AMOLED display with 120 Hz refresh rate and runs on the more powerful Dimensity 7200 chipset. It comes with a 5,000 mAh battery and 44W fast charging. If raw processing power matters most to you, the Vivo T3 5G has a slight edge. But the OPPO F31 5G Phone wins with its larger 5,600 mAh battery and 256 GB storage option.
OPPO F31 5G vs Realme 13 Pro
The Realme 13 Pro is also worth mentioning. It delivers solid camera performance and a good display. However, the OPPO F31 5G Phone holds its own with its massive battery and elegant design.
In the end, your choice depends on what matters most to you. If battery endurance and storage are your priorities, the OPPO F31 5G Phone is the clear winner. If you want more processing power for gaming, you might lean towards the Vivo T3 5G instead.
Pros And Cons of OPPO F31 5G Phone
Let us quickly summarize the good and the not-so-good aspects of this phone.
What we liked. The large 5,600 mAh battery easily lasts a full day. The 45W SUPERVOOC charging is fast and convenient. The 6.72-inch AMOLED display looks vibrant and smooth at 120 Hz. The 256 GB storage gives you plenty of room. The design looks premium and feels comfortable in hand. The IP64 rating adds a layer of protection against dust and water.
What could be better. The dual camera setup lacks an ultrawide and macro lens. The Dimensity 6300 is not the most powerful chipset in this price range. Low-light camera performance is just average. ColorOS comes with some pre-installed bloatware.
Who Should Buy OPPO F31 5G Phone?
The OPPO F31 5G Phone is ideal for you if you want a 5G-ready smartphone without spending too much. It is perfect for people who prioritize battery life and hate charging their phone multiple times a day. If you love watching videos and want a beautiful AMOLED display for media consumption, this phone delivers. The 256 GB storage is great for users who store lots of photos, videos, and apps. And if you simply want a phone that looks and feels premium without the premium price tag, the OPPO F31 5G Phone fits the bill perfectly.
However, this phone might not be the best choice if you are a heavy gamer who needs top-tier performance. It is also not ideal for professional photographers or anyone who specifically needs an ultrawide camera lens.
Final Verdict
The OPPO F31 5G Phone is a well-rounded mid-range smartphone that gets the basics right. It offers a stunning display, long-lasting battery, fast charging, and reliable everyday performance. The design looks premium, and the 256 GB storage is generous for the price.
Yes, it has a few shortcomings. The camera setup could have been more versatile with additional lenses, and the processor is not the most powerful in its class. But for the average user who values battery life, display quality, and a smooth daily experience, the OPPO F31 5G Phone delivers excellent value at ₹26,999.
If those are the things that matter most to you, go ahead and add it to your cart. You will not be disappointed.
