Design and build
Clean A series look, flat sides, and three finishes. The phone is IP54 rated for dust and splash, and OPPO says it passed MIL-STD-810H shock/drop tests. It’s still not waterproof, and liquid damage isn’t covered under warranty, so be careful around pools and sinks.
Display and sound
The 6.67-inch screen runs up to 120Hz for smooth scrolling and can push up to 1000 nits outdoors. It supports Splash Touch, which keeps the touchscreen responsive with wet or greasy fingers, and Ultra Volume to boost call/media loudness up to 300% for noisy places. Cover glass is listed as twice-reinforced CSG/Panda.
Performance (everyday use)
The Dimensity 6300 is a modern 6nm chip with two Cortex-A76 performance cores and six Cortex A55 efficiency cores. In practice, it’s built for social apps, navigation, streaming, light gaming, and day-to-day multitasking without drama. If you push heavy 3D titles, you’ll need to dial graphics down.
Storage is eMMC 5.1, which is slower than UFS, but OPPO’s RAM Expansion helps smooth out app switching by using free storage as virtual memory. Reasonable for the price bracket.
Cameras
You get a single 8MP rear camera and a 5MP selfie camera. Daytime shots are fine for socials; low light is where it struggles. Video goes up to 1080p at 60fps on the rear and 1080p at 30fps on the front. There’s AI Portrait Retouching to tweak selfies, plus modes like Night, Extra HD, and Time Lapse.
Battery and charging
The 5100mAh battery is the star. With casual use (WhatsApp, YouTube, maps, music), a full day is easy, and lighter users can stretch to the next morning. 45W SUPERVOOC tops it up quickly; the phone also supports VOOC and PD 2.0, so your existing USB-PD charger will work just not at SUPERVOOC speeds. OPPO also claims the battery should retain ≥80% capacity after 4+ years in lab tests.
Software and updates
Ships with ColorOS 14.0.1. OPPO highlights a “36-month fluency” lab test and its Trinity Engine for stability and smoothness over time; real-world results vary with apps and storage fill-level.
Connectivity and extras
Dual-SIM 5G with India-relevant bands, Wi-Fi 5, Bluetooth 5.3 with SBC/AAC/LDAC, USB-C, and a 3.5mm headphone jack. You also get fingerprint and face unlock, and standard sensors (proximity, ambient light, compass, accelerometer). GNSS includes GPS, Galileo, GLONASS, BeiDou, and QZSS.
