Xiaomi 14 Ultra vs OnePlus 12: Design and Build
Both smartphones look and feel premium as they are well crafted for premium finish and high durability. However, the Xiaomi 14 Ultra has a nano-tech vegan leather finish on the back for better durability and protection against dust and scratches.
Both have nearly the same weight and dimensions. However, the Xiaomi 14 Ultra can better protect itself from water and dust because of the IP68 rating, whereas the OnePlus 12 is IP65 certified.
Xiaomi 14 Ultra vs OnePlus 12: Performance
Xiaomi 14 Ultra is powered by the Snapdragon 8 Gen 3 chip, which also powers the OnePlus 12. This doesn’t mean both smartphones have the same performance, at least what the benchmarking platforms tell.
On Geekbench 6, the Xiaomi 14 scored 2,145 in the single-core test and 6,523 in the multi-core test. The OnePlus 12, on the other hand, has managed to pull off 2,106 and 6,468 points in the single-core and multi-core tests, respectively.
The AnTuTu 10 benchmark also gives higher CPU, GPU, and memory scores to the Xiaomi 14 Ultra than the OnePlus 12.
Despite using the same chip, the smartphones have different results on benchmarking platforms because of software optimizations and heat management, among many other factors. However, the differences in scores are not significant, and so should be the real-life performance.
Xiaomi 14 Ultra vs OnePlus 12: Display
Both devices have a flat LTPO AMOLED screen that supports 1-120Hz variable refresh rate, HDR10+, and Dolby Vision. The differences that set them apart are a bigger display, higher peak brightness, and Gorilla Glass Victus 2 protection on the OnePlus 12.
The Xiaomi 14 Ultra has in-house Xiaomi Sheild Glass protection. And the device supports 68 times more colors than the OnePlus 12.
Xiaomi 14 Ultra vs OnePlus 12: Camera
The Xiaomi 14 Ultra has a massive camera module on the back that houses four sensors, all having 50MP resolution, each serving a different purpose.
The primary 50MP camera (Sony LYT-808) has f/1.63-f/4.0 variable aperture, 1-inch sensor size, and supports optical image stabilization (OIS). There’s also a 50MP (Sony IMX858) telephoto lens with f/1.8 aperture, 10cm macro, 3.2x optical zoom, and OIS support. The third 50MP sensor is a periscope lens with OIS, f/2.5 aperture, 30cm macro, and 5x optical zoom support. The last 50MP sensor is an ultrawide camera with f/1.8 aperture, 5cm macro, and 122° field of view (FOV).
Unlike the Xiaomi 14 Ultra, the OnePlus 12 has a total of three camera sensors in its rear camera setup, all with different resolutions. There’s a 50MP (Sony LYT-808) primary camera with OIS, f/1.6 aperture, 1/1.4-inch sensor size, and 85˚ FOV. The device also has a 64MP (OmniVision OV64B) periscope telephoto lens with OIS, f/2.6 aperture, ½-inch sensor size, and 3x optical zoom. Lastly, the OnePlus 12 has a 48MP (Sony IMX581) ultrawide sensor with f/2.2 aperture and 114˚ FOV.
Both smartphones can record up to 8K videos with their rear cameras, but the Xiaomi 14 Ultra supports higher fps. The same goes for the front camera, which supports higher fps video recording on the Xiaomi phone.
Xiaomi 14 Ultra vs OnePlus 12: Battery
The OnePlus 12 has a larger battery compared to the Xiaomi 14 Ultra. It also has faster charging support over a USB cable. However, the Xiaomi 14 Ultra wins at fast wireless charging, and it also supports reverse wireless charging, which the OnePlus 12 doesn’t.
The OnePlus 12 should offer more screen-on time and lesser time to refill the battery compared to Xiaomi 14 Ultra.
Xiaomi 14 Ultra vs OnePlus 12: Software
Both smartphones come with Android 14 out of the box, with a layer of custom skins (HyperOS for Xiaomi, OxygenOS for OnePlus) on top. They have been promised the same software support from their respective brands — 4 years of Android updates and 5 years of security updates.
Xiaomi 14 Ultra vs OnePlus 12: Connectivity
There’s not much to discuss on the connectivity front, as both devices have the same connectivity features. A minor difference is that the OnePlus 12 supports USB Type-C 3.2 Gen 1, whereas the Xiaomi 14 Ultra has USB Type-C 3.2 Gen 2. This means a faster data transfer speed on the Xiaomi phone over a USB connection.
