Xiaomi 15 vs OPPO Find X8 Comparison: Features, Performance, and More Differences

In 2025, a camera-focused flagship smartphone battle between Xiaomi and OPPO. This time, I would like to compare the Xiaomi 15 and the OPPO Find X8.

Compare the body designs of Xiaomi 15 vs OPPO Find X8 side by side.

Xiaomi 15

OPPO Find X8

Let's start by comparing the body designs.

The Xiaomi 15 is available in four colors: Liquid Silver, White, Black, and Green, offering a wide variety of options. Particularly, the Liquid Silver looks almost like liquid metal, making it a bold and striking color choice. It features a smooth, rounded, micro-curved aluminum frame design. The camera bump is covered by a single square glass panel that houses the triple-lens camera, maintaining a simple yet high-quality appearance.

The OPPO Find X8 comes in two colors: Space Black and Star Grey. Although it has fewer color options, both are fitting for a flagship model. The camera bump features a distinctive circular Cosmos Ring design, which may be polarizing. If you're concerned about it, the Space Black option, where the Cosmos Ring is also black, might be a better choice.

Both are standard models within their flagship range, so the concept of simple yet high-quality design remains unchanged. The Xiaomi 15 is more neutral and easier to accept, while the OPPO Find X8, with its prominent Cosmos Ring at the center, strongly emphasizes its identity as a camera-focused smartphone through its design.

Compare the Xiaomi 15 vs OPPO Find X8 Body and Display at Actual Size

Let's compare the body and display dimensions side by side.

A significant difference is that the Xiaomi 15 is quite compact. As smartphones have become larger in recent years, if you're looking for a high-performance, compact device, the Xiaomi 15 would be the choice.

On the other hand, the OPPO Find X8 is larger, roughly the size between the iPhone 16 and iPhone 16 Pro Max, making it not excessively large. It goes without saying that a larger screen makes it easier to view content. Whether you prefer a compact size or a larger one, we recommend taking the time to compare the feel of these sizes here on this site.

Both displays are AMOLED. The resolution is almost identical, and the refresh rate is the same. However, the maximum brightness differs: the Xiaomi 15 reaches 3,200 nits, while the OPPO Find X8 can achieve up to 4,600 nits, but only in HDR mode, offering brighter display capabilities.

Both displays are flat, not curved, which should make them easier to use.

Both have ultra-thin bezels, with the Xiaomi 15's bezel being 1.38mm and the OPPO Find X8's at 1.45mm. Although the Xiaomi 15 has a slight numerical edge, the difference is minimal (only 0.07mm), meaning both devices have very thin bezels. However, thinner bezels can cause issues when control buttons appear near the edges of the screen, making them harder to press. While this design is modern, it can negatively affect usability. If this is a concern, it might be better to consider other smartphones with slightly thicker bezels.

Compare Xiaomi 15 vs OPPO Find X8 in a Specifications Chart

Let’s compare the cameras.

Both the Xiaomi 15 and OPPO Find X8 have unified 50MP wide, ultra-wide, and telephoto cameras, designed to maintain consistent image quality even when changing focal lengths. Both front cameras are 32MP, offering similar performance.

One key difference is in the telephoto capabilities. The Xiaomi 15 features optical 2.6x zoom and lossless 5x zoom, while the OPPO Find X8 uses a W-type prism lens with optical 3x zoom and can achieve up to 6x in lossless zoom. This makes the OPPO Find X8 superior in terms of telephoto zoom.

Both phones are co-developed with renowned camera brands, as the Xiaomi 15 features Leica and the OPPO Find X8 features Hasselblad. These collaborations reflect the philosophies and brand concepts of the camera makers. Leica is known for its artistic approach, while Hasselblad is recognized for its professional heritage. This results in a deeper, more nuanced camera experience, and the choice between the two will ultimately come down to personal preference, which can be best judged by looking at real-world photos taken with each device.

In terms of weight, the Xiaomi 15 weighs 191g, while the OPPO Find X8 is slightly heavier at 193g. However, considering the OPPO Find X8 has a larger display and a bigger battery—5,240mAh for the Xiaomi 15 and 5,630mAh for the OPPO Find X8—it could be argued that the OPPO Find X8 is actually the lighter option when taking these factors into account.

Both smartphones are equipped with high-end processors: the Xiaomi 15 uses the Snapdragon 8 Elite, and the OPPO Find X8 has the MediaTek Dimensity 9400. There is not a significant performance difference between the two as both are flagship processors.

In terms of memory, the Xiaomi 15 offers 12GB of RAM, while the OPPO Find X8 comes with 16GB, giving it more headroom. Storage options are also different, with the Xiaomi 15 offering 256GB and 512GB models, while the OPPO Find X8 only has a 512GB option. Since the Xiaomi 15 starts at the 256GB model, if we compare the same 512GB model, the OPPO Find X8 will likely be more affordable.

When it comes to water and dust resistance, the Xiaomi 15 has an IP68 rating, while the OPPO Find X8 has an IP69 rating, meaning the OPPO model is more resistant to high-pressure, high-temperature water jets.

Both devices support eSIM, but neither supports Felica (mobile payment), though both are compatible with NFC.

In the end, which is better, Xiaomi 15 vs OPPO Find X8?

In the same price range, the OPPO Find X8 can be considered superior in terms of performance.

However, the standout feature of the Xiaomi 15 is its compactness. If you’re looking for a compact smartphone with the Snapdragon 8 Elite, or if you’re attracted to a flagship smartphone co-developed with Leica that offers up to 5x lossless zoom, the Xiaomi 15 would be the choice.

On the other hand, the OPPO Find X8 offers a more balanced package in terms of processor, battery, storage, and camera performance at this price point. Additionally, with its Hasselblad co-developed camera and the ability to achieve 6x lossless zoom, the OPPO Find X8 is particularly strong in telephoto capabilities.

That said, both phones are flagship models that reflect the brand image of well-known manufacturers and are highly refined. While it’s a tough decision, understanding the points mentioned above and comparing the size and feel on this site will ensure that you won’t regret your choice, no matter which smartphone you opt for.
