Flagship smartphones continue to evolve, and this year the biggest rivalry is between the OPPO Find X9 and the OnePlus 15. Both models bring premium hardware, high-end cameras, and powerful chipsets, making the decision difficult for buyers. With features like a 165Hz refresh rate on the OnePlus 15 and the new MediaTek Dimensity 9500 powering the OPPO Find X9, the comparison becomes even more interesting.
Design and Build
From the rear, both phones look surprisingly similar. While the OPPO Find X9 comes in Space Black and Titanium Grey finishes, OnePlus takes a bolder approach with Infinite Black, Sand Storm, and a more striking Ultra Violet option. The Find X9 offers a smaller 6.59-inch display, making it easier to grip and use, whereas the OnePlus 15 features a larger 6.78-inch screen.ience
Both smartphones share similar display resolutions, offering a crisp 1.5K viewing experience with high brightness levels of up to 3600 nits. However, performance-oriented users may lean toward the OnePlus 15 because of its 165Hz refresh rate, which also enhances gaming at 165fps. The Find X9 stays at a 120Hz refresh rate, which is still smooth, but not as gaming-focused as its competitor.
Camera Capabilities
Both smartphones share a triple 50MP camera system, including wide, ultra-wide, and telephoto lenses. The OnePlus 15 offers a 3.5x optical zoom, slightly more than the Find X9’s 3x zoom. OPPO brings Hasselblad tuning and its new LUMO Imaging engine, while OnePlus introduces its DetailMax Engine for sharper photography. Both devices use the same 32MP front camera setup.
Battery and Charging
Battery capacity is another area where both phones impress. With more than 7,000mAh battery packs, they easily stand out among premium phones. The OnePlus 15 holds a slight advantage with a 7,300mAh battery and 120W fast charging. OPPO offers 7,025mAh capacity with 80W fast charging. Both support 50W wireless charging, making them strong performers in endurance.
