Phone Comparisons: Xiaomi 13 Ultra vs OPPO Find X6 Pro

This time around, we’re comparing the Xiaomi 13 Ultra vs OPPO Find X6 Pro. These two smartphones are amongst the most powerful devices on the market at the moment. Both of them come from well-known China-based smartphone manufacturers, and both are heavily focused on the camera experience. They have another thing in common, they’ve both been released in China only, for now. The Xiaomi 13 Ultra is coming to global markets for sure, but the Find X6 Pro may not launch outside of its homeland. We’ll see.

Having said that, both are perfectly usable outside of China, even with China-based software. I’ve reviewed them after quickly sideloading Google services, and it turns out they are true powerhouses. You can check out their specs below, and following that, we’ll compare the two devices across a number of other categories, including design, display, performance, battery life, cameras, and audio performance.

Xiaomi 13 Ultra vs OPPO Find X6 Pro: Design

Both of these smartphones have curved displays, and huge camera oreos on the back. They’re both large, and utilize vegan leather on the back (more on that later). The implementations are different, and they’re not that similar design-wise. Well, they are if you look at them from the front, but the moment you flip them over, or start handling them, you’ll notice plenty of differences. Both smartphones have a centered display camera hole at the top of their displays, and both include thin bezels.

The Xiaomi 13 Ultra is a bit heavier at 227 grams, compared to 216/218 grams of the OPPO Find X6 Pro. The Find X6 Pro comes in two different build variants, one has a glass backplate, and the other combines vegan leather with glass. They’re very similar when it comes to height, while the Xiaomi 13 Ultra is a bit narrower. They’re equally thick, well, at least at the thinnest point.

The Xiaomi 13 Ultra is thinner in the lower portion of its body, as the thickness gradually increases towards the camera oreo. Xiaomi did this to hide the camera bump a bit, as it would be truly gigantic otherwise. That hill also serves as a good anchor point for your finger when you’re holding the device. The vegan leather backplate does not curve into the sides of the phone, it transfers to metal on the back itself. This is a rather interesting implementation. The vast majority of the Find X6 Pro’s backplate is covered by vegan leather, while the top portion is covered by glass. The glass model has glass only on the back, though, of course.

Both of these phones are quite large, and are not exactly easy to use with one hand. Their weight doesn’t help things. The vegan leather on the back does add some grip to the equation, so that’s good if you plan on using them without a case. That’s not something we’d recommend, however, mainly because of those huge camera oreos on the back. Both phones feel sturdy in the hand, and well-built.

Xiaomi 13 Ultra vs OPPO Find X6 Pro: Display

The Xiaomi 13 Ultra features a 6.73-inch QHD+ (3200 x 1440) LTPO AMOLED display. That panel can project up to 1 billion colors, and supports a 120Hz refresh rate (adaptive). Dolby Vision is also supported, as is HDR10+ content. This display gets immensely bright, as its brightness goes up to 2,600 nits at its peak. We’re looking at a 20:9 display aspect ratio here, and this panel is curved. It is protected by the Gorilla Glass Victus.

The OPPO Find X6 Pro, on the flip side, has a 6.82-inch QHD+ (3168 x 1440) LTPO3 AMOLED display. This display is also curved, and it has a 120Hz refresh rate (adaptive). Dolby Vision is supported, as is HDR10+ content. This panel also gets immensely bright, up to 2,500 nits. These are actually two of the brightest displays on the market now. This display is protected by the Gorilla Glass Victus 2.

Both of these displays are outstanding in every way. They’re not only immensely bright, and easily usable outdoors, but are also extremely sharp and vivid. They offer great viewing angles, and the blacks are deep. Touch response is excellent on both smartphones too. I enjoyed using both panels, and quite frankly, don’t have any complaints here. They can also be tuned to your preference in the settings.

Xiaomi 13 Ultra vs OPPO Find X6 Pro: Performance

You will find the Snapdragon 8 Gen 2 SoC inside both of these smartphones. That is Qualcomm’s most powerful processor to date. In both smartphones, that SoC is backed by LPDDR5X RAM and UFS 4.0 flash storage. Both phones offer up to 16GB of LPDDR5X RAM. The specs are there, but what’s the performance like? Well, outstanding, as far as general operational smoothness is concerned.

Both of these phones are buttery smooth. It doesn’t really matter what you’re doing at the moment, they can do easier tasks without a problem, and the same goes for more demanding operations. Opening apps is a breeze, as is browsing, image and video processing, media consumption, and so on. Even if you love gaming, both of these phones can deliver. Even when it comes to the most demanding games out there, it’s not a problem. These are some of the most powerful devices you’ll find in the market at the moment. Do note that both are running software made for China at the moment.

Xiaomi 13 Ultra vs OPPO Find X6 Pro: Battery

A 5,000mAh battery sits inside each of these two smartphones. The battery life is not the same, but it is comparable. The Snapdragon 8 Gen 2 is great when it comes to power consumption, and having the latest RAM and storage units definitely helps too. Both smartphones can cross the 8-hour screen-on-time mark, at least they did for us. They won’t offer the same level of battery life as the Galaxy S23 Ultra or OnePlus 11, but they’re outstanding in that regard regardless.

Even power users should be happy with the battery life here. Do note that gaming could affect the battery life negatively, I didn’t really play any games outside of specific game testing. I am a power user, though, so take that into account. Your apps, usage, and signal strength will be different, though, so your mileage will vary, the question is by how much. One thing is for sure, though, they both offer great battery life.

As far as charging is concerned, they’re both well-equipped. The Xiaomi 13 Ultra supports 90W wired, 50W wireless, and 10W reverse wireless charging. The OPPO Find X6 Pro supports 100W wired, 50W wireless, and 10W reverse wireless charging. Do note that both smartphones ship with proper charging bricks, so that you can take advantage of the fastest charging available.

Xiaomi 13 Ultra vs OPPO Find X6 Pro: Cameras

When it comes to cameras, both smartphones have outstanding hardware. The Xiaomi 13 Ultra has four 50-megapixel cameras. A 50-megapixel main camera (1-inch sensor, variable aperture) is backed by a 50-megapixel ultrawide camera (122-degree FoV), and a 50-megapixel telephoto camera (3.2x optical zoom). A 50-megapixel periscope telephoto camera (5x optical zoom, 120x digital zoom) is also included. Leica lenses are included.

The OPPO Find X6 Pro, on the other hand, offers three 50-megapixel cameras on the back. A 50-megapixel main camera (1-inch sensor) is included, alongside a 50-megapixel ultrawide camera (110-degree FoV), and a 50-megapixel periscope telephoto unit (2.8x optical zoom, 120x digital zoom). These cameras are backed by Hasselblad, who also handles color tuning.

Both of these smartphones are outstanding when it comes to camera performance. The images they provide during the day, with that 1-inch camera are outstanding. The colors are spot on, and the vignetting effect is noticeable on the Xiaomi 13 Ultra. You can counter that via a different Leica shooting mode, though. The natural bokeh looks great on both phones, while the images are extremely well-balanced. In low light, those sensors can pull in a lot of light, and without a ton of processing or sharpening, provide truly detailed photos. The OPPO Find X6 Pro images do tend to be slightly brighter, but the details are on par with them.

Ultrawide cameras are great on both devices. The Xiaomi 13 Ultra’s has a wider field of view, but the OPPO Find X6 Pro’s does a slightly better job in low light. The telephoto camera on the phone also handles low light slightly better, while both of those telephoto cameras are great for portraits, actually. The periscope telephoto units are truly useful in good lighting, but even if there’s not a ton of light around, they’re still perfectly usable. The OPPO Find X6 Pro’s periscope telephoto unit does handle low light situations a bit better, actually, perhaps even better than any other implementation out there. The selfie camera is not the Xiaomi 13 Ultra’s strong suit, the one on the Find X6 Pro does a better job.

Audio

You will find a set of stereo speakers on each of these two smartphones. Those speakers are actually really good in both cases, though they do sound a bit different. The soundstage is wide enough, and the sound is detailed, with even some bass thrown into the mix.

If you want to plug in your wired headphones, you’ll have to use a dongle, as neither phone has an audio jack. If you prefer to handle things wirelessly, the good news is that both devices do support Bluetooth 5.3.
