Oppo F31 Pro+ review
The F31 Pro+ suits someone who prioritizes battery endurance and water resistance over camera versatility or display sharpness, especially in climates or lifestyles where phone durability is a real concern. Those chasing zoom, sharp screens, or a performance edge should cross-shop rivals with optical telephoto lenses or higher refresh rates at the same price.
This review is based on Oppo’s published specifications and public benchmark data for the Oppo F31 Pro+, and the rating is spec-based. GoSolo does not physically test devices; where we estimate real-world behaviour such as battery life or charge time, we say so. How we rate phones.
Overview
The F31 Pro+ packages a 7000mAh battery, Snapdragon 7 Gen 3, and a solid AMOLED display into a water-resistant phone at €320, but the 50MP camera lacks zoom and the Snapdragon 7 is starting to feel ordinary for the price point in 2025.
Design & build
At 195–204g with a 7.7mm frame, the F31 Pro+ is thin and light enough to forget in your pocket, though leaning towards the heavier end for its size class. The real story is the IP68/IP69 certification: this phone survives dust, fresh-water submersion to 1.5 meters for 30 minutes, and high-pressure water jets without flinching. That level of durability is typically reserved for flagship or rugged phones, not a €320 mid-ranger. MIL-STD-810H compliance backs it up. For someone in a climate with monsoons, pool trips, or just everyday spillage anxiety, this is a meaningful advantage. The 89.1% screen-to-body ratio keeps bezels minimal, and the three color options (Festival Pink, Himalayan White, Gemstone Blue) suggest Oppo is thinking about regional taste, not one-size-fits-all design.
Display
The 6.8-inch AMOLED screen with 1600 nits (HBM) and 120Hz refresh rate delivers solid day-to-day quality. Outdoor brightness is genuinely useful—you won't squint at maps or video in sunlight. The 120Hz keeps scrolling through feeds and apps smooth, though you won't see frame-rate differences in static content. However, the 453 ppi density on this screen size sits at the floor of "acceptable." On a 6.8-inch panel, pixels are just visible at reading distance if you look closely; sharper rivals pack 500+ ppi at the same diagonal. The AMOLED blacks are, as always, ink-deep, and the 19.5:9 ratio gives you extra vertical real estate—useful for reading and productivity. AGC's DT-Star D+ glass provides scratch resistance, though it's not Gorilla Glass and will show fingerprints readily.
Performance
The Snapdragon 7 Gen 3 is the chip that now defines the upper midrange in 2025. It runs everyday apps and social media without stutter, handles video editing and photo processing in real time, and plays mid-tier games (PUBG on medium settings, Genshin at 60fps on balanced) comfortably. For spreadsheets, email, music, and streaming, you'll never feel it strain. The Adreno 720 GPU is respectable but not gaming-focused; demanding 3D titles at max settings will throttle to lower frame rates. With 8GB or 12GB RAM and UFS 3.1 storage, app launching and file transfers feel snappy. The problem is that this exact chipset now appears in dozens of phones at this price, so you're not getting a performance edge—you're getting parity with what buyers at €300–400 have come to expect.
Software
ColorOS 15 on Android 15 is Oppo's skin, and it's typically clean and fast compared to heavier skins from other makers. Oppo is less known for bloatware than Samsung or some Chinese brands, and updates roll out on a reasonable schedule. One caveat: regional variants matter. If you're outside Oppo's primary markets (Southeast Asia, India), software support and local feature parity can lag. The software itself doesn't break anything or introduce weird quirks; it gets out of your way.
Camera
The main camera is a 50MP sensor with f/1.8 aperture, PDAF, and optical image stabilization—a solid foundation for a mid-ranger. The f/1.8 aperture gathers enough light for low-light scenes, and OIS keeps video steadier than electronic stabilization alone. Daytime shots are clean and detailed, and the color spectrum sensor helps white balance stay true. The problem is the absence of optical zoom. Rivals in this band often pack a 2x or 3x telephoto lens; the F31 Pro+ makes do with digital cropping of the 50MP sensor, which degrades quality fast. If you photograph distant subjects or sports, you'll feel this omission. The 32MP selfie camera at f/2.4 is adequate for video calls and social media; low-light selfies won't win beauty pageants, but they're usable. Video caps out at 4K 30fps on the main sensor, which is behind flagships but fine for vlogging and casual capture. The gyro-EIS on both cameras smooths handheld footage.
Battery & charging
The 7000mAh capacity is overkill in the best way. With mixed use—social media, email, video streaming, music—expect 6 to 8 hours of screen-on time, comfortably lasting from morning to bedtime, even if your day is heavy on gaming or video. If you're a light user (chat, email, browsing), a single charge easily stretches to two days. The 80W wired charging refills the battery in about 30 to 40 minutes flat, and Oppo's 42%-in-20-minutes metric means a quick top-up before leaving home is practical. The 10W reverse charging (wireless out to other devices) is a nice-to-have for emergencies. No wireless charging on the phone itself—at €320, that's a cost trade-off, not a missing feature. In a region where power cuts or inconsistent grid access is common, this battery capacity is peace of mind.
Value & verdict-context
At €320, the F31 Pro+ sits in the crowded upper-midrange tier where Snapdragon 7 Gen 3 has become table stakes. The standout is the IP68/IP69 water and dust rating, which is genuinely uncommon at this price and justifies a conversation if durability matters to you. The battery capacity and charging speed are also above what you'd expect, and the display is competent if not cutting-edge. However, the camera lacks zoom, the screen density is ordinary, and the chipset offers no performance surprise. If you live somewhere with heavy monsoons, water exposure, or just chronic phone-droppings, the durability rating alone might sway you. If you value zoom for photography, want the sharpest screen, or expect a chipset bump for your budget, look elsewhere. For casual users who want a reliable, tough phone that doesn't die mid-day, this is a solid pick.
Verdict
The F31 Pro+ suits someone who prioritizes battery endurance and water resistance over camera versatility or display sharpness, especially in climates or lifestyles where phone durability is a real concern. Those chasing zoom, sharp screens, or a performance edge should cross-shop rivals with optical telephoto lenses or higher refresh rates at the same price.
- 7000mAh battery with 80W charging gets you through a full day without strain and refills quickly (42% in 20 minutes)
- 1600-nit AMOLED display stays readable in direct sunlight and 120Hz scrolling feels smooth; 6.8-inch screen is spacious without being unwieldy
- IP68/IP69 rating (water to 1.5m for 30min, high-pressure jets) is real durability at this price, not marketing
- Snapdragon 7 Gen 3 handles everyday apps, mid-range gaming, and video editing without compromise
- No optical zoom—the 50MP main camera can crop digitally, but distant subjects stay small compared to rivals with telephoto or periscope lenses
- Snapdragon 7 Gen 3 is now common in the €300–400 bracket, so no real performance advantage over close competitors
- 453 ppi pixel density on a 6.8-inch screen is standard, not sharp; text and icons aren't as crisp as higher-density displays at this size
