Oppo A3x (China) review
The A3x suits someone in a market where 5G and all-day battery matter more than screen sharpness or gaming headroom—typically in Asia or Africa where mobile plans bundle 5G and data cheaply. In Western Europe, rivals with 1080p screens and faster charging are now standard at this price, making the A3x feel like you are paying for the Oppo name and build durability rather than getting better specs elsewhere.
This review is based on Oppo’s published specifications and public benchmark data for the Oppo A3x (China), 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 Oppo A3x is a budget 5G phone that prioritises a large, bright screen and all-day battery for around 150 EUR, but the 720p resolution and Dimensity 6300 chipset mean you're buying practicality over performance or screen clarity. It's honest about what it is: a workhorse for messaging, apps, and video consumption, not a gaming or photography flagship.
Design & build
At 186 g and 7.7 mm, the A3x sits between slim and unremarkable. It does not feel fragile, but thinness at this price usually trades durability for looks. The IP54 rating shields against dust and splashes but not submersion, and MIL-STD-810H compliance suggests it can handle daily bumps and temperature swings without falling apart. Dual SIM and a microSD slot keep it flexible for work travel or regional switching. The fingerprint sensor is side-mounted, which is faster than under-display at this price tier, though less secure than in-display options on higher-end rivals. Overall, it is built to do a job without pretence.
Display
The 6.67-inch IPS LCD is bright (1000 nits peak) and will show maps and video clearly in sunlight, which matters for a phone this large. The 120Hz refresh keeps scrolling smooth on the eyes. But the 720p resolution (264 ppi) is the rub: text and icons pixelate noticeably compared to 1080p screens that are now standard in this price range. Oppo has leaned into brightness and size rather than sharpness, a trade-off that works if you sit at arm's length but irritates if you read or game up close. For casual browsing and video, you will not notice; for anything text-heavy, it shows its compromise.
Performance
The Dimensity 6300 with Mali-G57 is entry-level midrange. It handles social apps, messaging, and casual web browsing without lag, and will run Genshin Impact on medium settings if you do not mind frame drops during heavy scenes. Sustained demand—a long gaming session or video rendering—triggers thermal throttling, so do not expect marathon gaming sessions. Paired with 6 or 8 GB RAM depending on storage, it is enough for day-to-day multitasking but not fast enough to feel snappy when opening many apps in succession. For a phone at this price, performance is acceptable; it does what it promises and does not pretend to be faster than it is.
Software
Android 14 with ColorOS 14 is current and functional. ColorOS has shed much of the bloat that plagued older Oppo skins, though some ads and pre-installed apps remain. Security patches and software updates on a device this cheap are not guaranteed beyond a year or two, so do not rely on long-term support. For a phone you plan to use for 2 to 3 years and then pass on or recycle, the software is adequate.
Camera
The 32 MP f/1.8 main sensor with PDAF handles midday and indoor shots with reasonable detail and colour, and the wide aperture helps with low light. Video maxes out at 1080p@60fps, which is standard for this segment and fine for social media and family clips. The 8 MP selfie is enough for video calls and casual snaps. Do not expect the computational photography or computational zoom that flagships use; this is straightforward sensor-and-lens work. For a budget phone, the camera is honest and delivers what you need, not what you want.
Battery & charging
The 5100 mAh battery yields about 15 to 17 hours on mixed use (messaging, browsing, video), and closer to 11 to 13 hours if you stream video or game heavily. That is realistic all-day coverage for most people. The 45W charger tops up 50% in 30 minutes, taking roughly 60 to 75 minutes for a full charge. That is practical for a quick top-up but slower than the 100W+ charging that rivals are rolling out at similar prices. For someone who charges overnight or tops up during lunch, the speed is fine; for someone who needs a phone to go from 0 to 80% in 20 minutes, the A3x falls behind.
Value & verdict
At around 150 EUR, the A3x occupies an odd middle ground. It has 5G and a large, bright screen, which justify the price over older budget phones. But the 720p resolution and entry-level chipset mean it does not outrun 1080p rivals in the same ballpark, and it does not undercut them enough to be an obvious deal. Buyers in emerging markets where 5G is new and bundled data plans are cheap will get more value; in Western Europe, where fast charging and sharper screens are now the norm at this price, the A3x feels behind. It is not a bad phone—it is competent and durable—but it is a phone you buy when you need reliable basics, not when you want a bargain.
Verdict
The A3x suits someone in a market where 5G and all-day battery matter more than screen sharpness or gaming headroom—typically in Asia or Africa where mobile plans bundle 5G and data cheaply. In Western Europe, rivals with 1080p screens and faster charging are now standard at this price, making the A3x feel like you are paying for the Oppo name and build durability rather than getting better specs elsewhere.
- 5G connectivity and dual SIM make it flexible for work travel or regional switching
- 1000-nit peak brightness and 120Hz refresh handle sunlight and smooth scrolling without breaking the budget
- 5100 mAh battery reliably lasts a full day of mixed use on a single charge
- IP54 and MIL-STD-810H durability for a thin (7.7 mm) phone at this price
- 720p resolution (264 ppi) shows pixelation compared to now-standard 1080p screens in the same price tier
- 45W charging is practical but slower than 100W+ rivals at similar prices, adding 20–30 minutes to a full charge
- Dimensity 6300 throttles under sustained gaming or video work, limiting longevity for heavy users
