Oppo Find X9 5G vs OnePlus 15 5G: Which Flagship Should You Buy?

The premium smartphone market in India has a new entrant with Oppo officially introducing the Find X9 5G series.

With upgraded cameras, a more powerful chipset and longer battery life, the Find X9 aims to take on the other flagship launches of 2025. One of its closest rivals is the OnePlus 15 5G, which falls within a similar price bracket and offers a similar design philosophy.

Although Oppo also unveiled a Pro model, the standard Find X9 competes more directly with the OnePlus 15 due to their comparable specifications and pricing. If you are looking to buy a high-end smartphone this year, here’s a complete comparison of the Oppo Find X9 5G and the OnePlus 15 5G across design, display, camera, performance, battery life and software support.

Design and Build Quality

At first glance, the Oppo Find X9 5G and OnePlus 15 5G look nearly indistinguishable.

• Both devices feature a minimalist aesthetic with flat front and rear panels and gently curved sides for better grip.
• They also sport a square-shaped camera module positioned on the top-left corner — a design trend increasingly seen in premium smartphones.
• The arrangement of sensors and LED flash differs between the two models, giving each brand a slightly unique identity.
• Oppo offers the Find X9 in two subtle shades — Space Black and Titanium Grey — suitable for those who prefer understated finishes.
• OnePlus adds a touch of flair with Infinite Black, Sandstorm, and the eye-catching Ultraviolet variant, which may appeal to users who want a more vibrant device.

In terms of durability, both phones come with IP68 water and dust resistance, but OnePlus goes a step further with an IP69K certification, offering an additional layer of resilience against high-pressure water jets.

For display protection, both devices use Corning Gorilla Glass Victus 2, which provides improved scratch and drop resistance.

Display: OnePlus Takes the Lead

• The Oppo Find X9 5G is equipped with a 6.59-inch AMOLED display that supports a 120Hz refresh rate. It’s slightly smaller, making the phone more compact and easier to handle with one hand.

The AMOLED panel promises vibrant colours, deep blacks and smooth touch response.

• The OnePlus 15 5G offers a more advanced 6.78-inch LTPO AMOLED display with a 165Hz refresh rate. The LTPO technology enables dynamic refresh rate adjustments, contributing to better battery life and smoother animations.

For gamers and heavy multimedia consumers, the OnePlus 15’s display has a noticeable advantage in fluidity and visual performance.

Performance and Battery

Under the hood, the two phones use different high-end chipsets.

• The Oppo Find X9 5G runs on the MediaTek Dimensity 9500, paired with up to 16GB of RAM. This chipset is designed for flagship performance and efficient multitasking.
• The OnePlus 15 5G, on the contrary. is powered by the Qualcomm Snapdragon 8 Elite Gen 5, also paired with up to 16GB RAM. Snapdragon chipsets are traditionally known for superior sustained performance, better GPU output and more stable thermals.

While both processors are capable of handling demanding workloads, early expectations tilt slightly in favour of the Snapdragon-based OnePlus 15 for performance-heavy users.

• On the battery front, Oppo packs the Find X9 with a 7025mAh battery that supports 80W wired charging.
• OnePlus edges ahead again with a 7300mAh battery and 120W SuperVOOC charging, enabling faster top-ups and longer battery life during intensive usage.

For users who value speed and longevity, the OnePlus 15 holds a mild advantage here.

Camera Comparison

Both devices feature a 50MP triple-camera setup, but their approaches differ.

• The Oppo Find X9 benefits from Hasselblad-tuned lenses and Oppo’s new LUMO Imaging Engine, which focuses on colour accuracy, improved low-light performance and natural skin tones.
• The OnePlus 15 5G, meanwhile, offers stronger optical zoom capabilities with up to 3.5x optical magnification. Its in-house DetailMax Engine enhances texture clarity and sharpness, making it ideal for users who frequently take detailed landscape photos.

While OnePlus brings superior reach, Oppo may deliver more refined output in everyday photography thanks to Hasselblad lenses.

Software and Updates

Since ColorOS and OxygenOS are now largely unified, the user experience on both phones feels remarkably similar. The Oppo Find X9 5G ships with ColorOS 16, while the OnePlus 15 5G runs OxygenOS 16.

The biggest difference lies in the long-term support for both the devices.

• Oppo offers 5 major OS upgrades and 6 years of security updates.
• OnePlus provides 4 major OS updates and 6 years of security patches.

This means Oppo users will receive one extra Android upgrade over the device’s lifespan.

Price in India: Slightly Cheaper OnePlus

The Oppo Find X9 5G is priced at INR 74,999 for the 12GB RAM + 256GB storage variant. The OnePlus 15 starts at INR 72,999 for the same configuration, making it marginally more affordable.

Which One Should You Buy?

Both smartphones offer compelling features, but your choice depends on your priorities:

• Choose Oppo Find X9 5G if you want superior colour science, Hasselblad-tuned cameras, longer software support, and a compact form factor.
• Choose OnePlus 15 5G if you prefer a better display, faster charging, stronger chipset performance, and a more durable IP69K rating.

Both devices stand strong in the flagship category, but OnePlus edges ahead in raw hardware, while Oppo shines in imaging and long-term usability.
