Oppo A6x Comprehensive Review

Design and Build Quality

The Oppo A6x presents a modern and sleek design that aligns well with the mid-range smartphone market of 2025. Measuring 166.6 x 78.5 x 8.6 mm (6.56 x 3.09 x 0.34 inches) and weighing 212 grams (7.48 oz), the device offers a relatively large footprint but maintains an ergonomic feel in the hand considering its screen size and battery capacity.

Its build features a polycarbonate body with a practical matte finish, available in two color options: Olive Green and Ice Blue. The matte surface adds to the grip and reduces fingerprints, enhancing everyday usability. The side-mounted fingerprint sensor is well positioned for easy unlocking and security without compromising the aesthetics or thickness.

Dual Nano-SIM support boosts connectivity options for users who balance personal and professional contacts on one device or travel frequently.

Display Characteristics

Oppo A6x is equipped with a sizable 6.75-inch IPS LCD screen, offering an immersive viewing experience for gaming, video streaming, and multitasking. The display comes with a 120Hz refresh rate, which is a significant competitive advantage in this segment, delivering smooth scrolling and responsive touch input.

Despite its size, it maintains an approximately 85.2% screen-to-body ratio, granting users a modern edge-to-edge look with slim bezels. The screen resolution is 720 x 1570 pixels with a 19.5:9 aspect ratio, yielding a pixel density of about ~256 ppi. Although the display resolution does not reach Full HD+, the sharpness is sufficient for everyday use without excessive strain.

Brightness levels can reach up to 1125 nits in High Brightness Mode (HBM), ensuring legibility under direct sunlight — a vital feature for outdoor usage.

Performance and Hardware

At the heart of the Oppo A6x lies the MediaTek Dimensity 6300 chipset built on a 6 nm process. This octa-core processor features a configuration of 2 high-performance Cortex-A76 cores running at 2.4 GHz, complemented by 6 efficiency-focused Cortex-A55 cores clocked at 2.0 GHz. This balance enhances multitasking capabilities and power efficiency.

Graphics processing is handled by the Mali-G57 MC2 GPU, which adequately supports casual gaming and media consumption at the device’s native display resolution. While not designed for high-end gaming, this GPU is optimized for smooth performance in popular mobile titles.

Oppo offers multiple RAM and internal storage configurations to accommodate different user needs:

• 4GB RAM + 64GB storage
• 4GB RAM + 128GB storage
• 6GB RAM + 128GB storage

Expandability is available via a microSDXC card slot, enabling storage boosts when needed — a valuable feature for those with extensive media libraries or app collections.

Software and User Experience

Out-of-the-box, the Oppo A6x runs Android 15 paired with Oppo’s custom ColorOS 15 skin. This latest software version delivers a refined user interface that improves multitasking, offers smart notification management, and includes enhanced security features.

ColorOS 15 is renowned for its smooth animations, customization abilities, and productivity enhancements such as split-screen mode, always-on display, and quick app switching. Oppo’s software team has optimized the experience to run efficiently on devices like the A6x, ensuring that users benefit from the latest Android improvements without lag.

Camera System

Photography capabilities on the Oppo A6x are centered around a single 13MP rear camera sensor with an f/2.2 aperture and autofocus. Despite the single-lens setup, the device supports several useful shooting modes including HDR and panorama, which enhance image quality under various lighting conditions and enable wide landscape captures.

For video, the rear camera can record full HD 1080p footage at both 30 and 60 frames per second, giving users the flexibility to capture smooth videos suitable for social media and casual content creation.

On the front, the Oppo A6x sports a 5MP selfie camera with an f/2.2 aperture. The front camera is capable of 1080p video recording at 30fps, supporting decent video calls and selfies. While the megapixel count is modest, the camera software compensates with AI beautification and optimizations to deliver pleasing portraits in well-lit environments.

Battery Life and Charging

One of the most impressive features of the Oppo A6x is its high-capacity 6500mAh battery. This large battery size is designed to ensure exceptional endurance, capable of powering the phone comfortably through full days of intensive use or up to multiple days with moderate usage patterns.

Charging technology on this model is robust, with 45W wired fast charging support. In practice, this allows the battery to recharge rapidly, minimizing downtime and enhancing convenience for users who rely on quick top-ups during busy days.

Additionally, the device supports 33W PPS and 13.5W PD fast charging, making it compatible with various fast chargers, and it offers 5W reverse wired charging, enabling it to act as a power bank for smaller devices like Bluetooth earbuds or smartwatches.

Connectivity and Network Support

Oppo A6x is future-proofed with full 5G connectivity on a wide range of bands including 1, 3, 5, 8, 28, 38, 40, 41, 48, 77, and 78 (SA/NSA modes). This ensures compatibility with global 5G networks for fast internet speeds and low latency.

Supporting legacy technologies such as GSM, HSPA, and LTE across multiple bands (2G bands: GSM 850/900/1800/1900, 3G bands: HSDPA 900/2100, 4G bands: 1, 3, 5, 8, 19, 28, 38, 40, 41, 42, 48), the device remains versatile for varied network environments, making it suitable for international use.

Wireless features include Wi-Fi 802.11 a/b/g/n/ac with dual-band support, Bluetooth 5.4 with A2DP, LE, and aptX HD audio codec for high quality wireless sound. The GPS system is comprehensive, supporting GPS, GALILEO, GLONASS, BDS, and QZSS for accurate navigation.

Although NFC is not available, USB Type-C 2.0 with OTG functionality enables external device connectivity including flash drives, peripherals, and accessories. A 3.5mm headphone jack is retained, catering to users who prefer wired audio solutions.

Audio and Additional Features

Audio output relies on a loudspeaker that delivers clear sound suitable for calls, notifications, and media playback. The dedicated 3.5mm jack enables plug-and-play for headphones without requiring adapters.

The Oppo A6x incorporates several standard sensors including a side-mounted fingerprint reader, accelerometer, proximity sensor, and compass. These enhance security, convenience, and utility — for example, the compass benefits navigation apps, and proximity sensors allow screen behavior during calls.

Pricing and Market Position

At a competitive price point of approximately 120 EUR, the Oppo A6x is positioned firmly within the affordable mid-range segment. This pricing makes it an attractive option for users looking for a reliable daily driver with balanced specifications, 5G connectivity, and long battery life without breaking the bank.
