Oppo Find X9 Pro review

6.78-inch OLED display is unchanged, still great

The Find X9 Pro is equipped with an 6.78-inch LTPO OLED display. It has a 1272x2772px resolution - weirdly, that's 8px wider and 8px shorter than the Find X8 Pro's panel. The aspect ratio is 19.6:9 with a pixel density of 450ppi. The refresh rate is dynamically adjustable in the 1-120Hz range, high-frequency 2160Hz PWM dimming should ensure a flicker-free experience, and wide-ranging HDR support is also on the menu.

Oppo says that the Find X9 Pro should be good for 800nits in manual operation and 1,800nits under bright ambient light (for a fully lit-up display). In our testing, we measured around 800nits for a 75% lit-up area when operating the slider manually, with a boost to just under 1,200nits under bright ambient conditions with the adaptive brightness enabled.

However, we veered a little off course and examined the same 75% pattern in Oppo's Photos gallery and got 1,803nits of max brightness.

Refresh rate

The Find X9 Pro's refresh rate implementation allows it to switch between various modes in the 1Hz to 120Hz range. It will base it on a combination of content and user interaction, with brightness seemingly not affecting it - we got 1Hz for idle states even at minimum brightness.

Our experience with high fps gaming on Oppo phones doesn't change with the Find X9 Pro - all titles we tried were capped at 60Hz/60fps.

Streaming and HDR

The Find X9 Pro supports all major HDR standards, including HDR10+ and Dolby Vision. Netflix was happy to serve both HDR10 and Dolby Vision video (depending on title), and we also got HDR streams on YouTube. The Widevine L1 certification means you get high-res playback of DRM protected content too.

As expected, the Find X9 Pro supports the Android Ultra HDR standard for displaying HDR photos with enhanced tone mapping and a brightness boost for highlights. It's implemented in Oppo's Photos gallery, where you get a button to turn it off on a photo-by-photo basis for comparison, in addition to being able to switch it off globally in settings. It also works in Google Photos (where you don't get the temporary preview button), and in Chrome - for images from other compliant phones, too.

Oppo Find X9 Pro battery life

The Find X9 Pro uses a silicon carbon battery with a whopping 7,500mAh capacity - one of the major upgrades compared to the previous generation. This large battery has also seemingly made it to the EU version of the phone unlike some competitors that get capacity reductions in some markets.

It should come as no surprise then that the Find X9 Pro returned superb endurance results, earning an Active Use Score of 21:57h - the highest result we've seen. Indeed, it would have been even higher, had it not been for the unremarkable call time - all the screen-on tests were stellar. The web browsing number is a chart-topper, as is the result in the video test, while the gaming test returned an all-time second-best figure. An overall impressive showing from the Find X9 Pro.

Our new Active Use Score is an estimate of how long the battery will last if you use the device with a mix of all four test activities. You can adjust the calculation based on your usage pattern using the sliders below. You can read about our current battery life testing procedure here. For a comprehensive list of all tested devices so far, head this way.

We have a couple of other Dimensity 9500 devices in testing (wink), and their call times are similarly low, so it would appear that high battery draw in this use case is characteristic of the chipset. We wouldn't be too worried about it, but if your smartphone usage has a high percentage or actual phonecall usage, you might want to consider other options.

Charging speed

The Find X9 Pro's specsheet lists an 80W charging capability with the company's proprietary SuperVOOC standard or up to 55W using USB Power Delivery. The phone doesn't come with a charger, but we had an 80W SuperVOOC adapter lying around and we tested with that one. We also tried with a high-quality aftermarket USB PD charger.

Charging speed is relatively good, when you take into account the capacity. We clocked a 1:07h time from 1% to 100% with the proprietary adapter (the meter maxing out at 67W), or 1:20h with the USB PD charger (43W peak). In both cases it took some extra time after the phone reported a fully charged state before it actually stopped charging the battery (13mins and 7mins respectively) - that's fairly standard behavior and the extra time tends to vary from charger to charger and even from run to run with the same charger.

So while it may seem like a good idea to grab a SuperVOOC charger to get the best possible charging speed, the intermediate measurements we got were essentially the same between the two standards - whether it's 53% or 54% at the half-hour mark doesn't feel like a meaningful difference, and certainly not one to warrant having a proprietary adapter instead of a good universal one.

The X9 Pro also supports wireless charging at up to 50W when using an in-house AirVOOC pad, which we didn't have available. When using a generic Qi2 compliant charger rated for 25W, we only got up to 7W on the input end of the charger, and it took some 9 hours from empty to full - so perhaps only viable for overnight charging. Reverse wireless charging is also supported, at up to 10W.

You get a fairly standard set of battery saver and battery health options. It has the Smart charging toggle that attempts to learn your charging habits and does the final top off just before it predicts you'll be needing the phone. It also allows you to set a limit on charging in 5% increments between 80 and 100%. You can also turn off the Smart rapid charging and have the Find charge slower than its maximum capability.

Speaker test

The Find X9 Pro has a two-speaker stereo system with one bottom-firing unit and another one above the display that directs sound towards the front and serves as an earpiece for voice calls. In a departure from previous implementations, where both speakers will also output the opposite channel's track at a lower volume, in addition to their own, the Find X9 Pro maintains strict channel separation. The channels are otherwise assigned based on the phone's orientation when it's held in landscape, while the top speaker gets the left channel when the handset is held vertically.

Bottom speaker • Top speaker/earpiece

The Find X9 Pro earned 'Good' rating for loudness in our test - a notch below last year's model, which is seemingly shaping up to be a trend this year. Oppo toned down the highs and the midrange, so the Find X9 Pro sounds more neutral than the previous generation. Both the iPhone 17 Pro Max and the Galaxy S25 Ultra sound better overall though, more bassy too.

Use the Playback controls to listen to the phone sample recordings (best use headphones). We measure the average loudness of the speakers in LUFS. A lower absolute value means a louder sound. A look at the frequency response chart will tell you how far off the ideal "0db" flat line is the reproduction of the bass, treble, and mid frequencies. You can add more phones to compare how they differ. The scores and ratings are not comparable with our older loudspeaker test. Learn more about how we test here.
