OnePlus 9 Pro vs Oppo Find X3 Pro: what's the difference?

OnePlus and Oppo are Chinese smartphone manufacturers that have proved themselves to deliver premium smartphones jam-packed with high-end features.

However, these features do vary depending on the brand and model. To make it a fair test, we're comparing the most expensive device from both the brands' flagship series; the OnePlus 9 Pro vs Oppo Find X3 Pro.

Here are the key differences as we assess price, design, camera set-up and battery life.


Revealed at a launch event on 11th March, the Oppo Find X3 Pro will set you back £1,099. The OnePlus 9 Pro is considerably cheaper - during a similar livestreamed event on 23rd March, it was confirmed that it will cost £829. So that's quite the difference.

However, Oppo does have cheaper options within its Find X3 series, including the Find X3 Neo for £699 and Find X3 Lite for a budget-friendly £399. To find out more about the affordable Lite model, read our Oppo Find X3 Lite 5G review.


Oppo Find X3 Pro

Both smartphones feature a 6.7-inch AMOLED display that offers a screen-to-body ratio of almost 90%.

When it comes to colour options, the Oppo Find X3 Pro is relatively subdued. There are just two colours available for this model; gloss black and gloss blue. There are three options for the OnePlus 9 Pro, too: Morning Mist, Pine Green and Stellar Black.


The camera on the Oppo Find X3 Pro is by far the most striking element of the phone. Seated on a raised bump, the quad-camera set-up includes a 50MP wide-angle camera lens, a 50MP ultra-wide-angle lens, a 13MP telephoto lens and a 3MP micro lens. This is in addition to the 32MP punch-hole front camera.

The camera set-up on the OnePlus 9 Pro has a more classic design but also contains four cameras made by Hasselblad. These are a 48MP main camera, a 50MP lens, an 8MP lens and a 2MP camera. The front camera on the OnePlus 9 Pro is also 32MP. These look like they'll shape up to be an undeniably stunning series of cameras - the Pro will be able to record video in 8K at 30fps and 4K at 120fps.

Battery life 

One of the most exciting additions to these two flagship smartphones is the ability to wireless charge. Both the OnePlus 9 Pro and Oppo Find X3 Pro are capable of being charged wirelessly and offer wired, fast-charging for those who prefer it.

With the 65W fast-charging offered by the Oppo Find X3 Pro, the phone can be charged up to 40% in just 10 minutes. In comparison, the OnePlus 9 Pro boasts it can charge from 1-100% in just 43 minutes.


A number of features, including 5G support, an in-screen fingerprint scanner and the top-of-the-line Qualcomm Snapdragon 888 chipset, can be found in both smartphones.

An IP68 rating for dust and water resistance is also assured for both models. This doesn't make them completely rugged but should offer a good level of protection.

Some of the other key features of the Oppo Find X3 Pro are the SGS eye care display certification and the ability to adapt to light conditions automatically. The Find X3 Pro also has a game focus mode, which will stop notifications and other distractions from ruining your streak just at the wrong moment.

Both Pro models also offer a 120 Hz refresh rate for smooth scrolling and 256GB of storage.

OnePlus 9 Pro vs Oppo Find X3 Pro: which smartphone should you buy?

The decision largely comes down to your budget. The OnePlus 9 Pro is considerably cheaper at £829, compared to the £1,099 price tag of the Oppo Find X3 Pro. Plus, there is some overlap when it comes to basic features. For example, both have a 6.7-inch AMOLED display, the new Qualcomm Snapdragon 888 chipset and an IP68 rating for dust and water protection.

Both also offer 5G capabilities and impressive quad-camera set-ups. There are some differences in the camera specs, but both offer sharp night shots and are unlikely to disappoint.

And that's the truth of it. You're unlikely to be disappointed with either of these smartphones; we are simply impressed with the OnePlus 9 Pro's value for money.

The Oppo Find X3 Pro 5G and OnePlus Pro 9 are both available to buy now.
