Xiaomi 15 vs POCO F7 Ultra Comparison: Features, Performance, and More Differences

In 2025, two smartphones from Xiaomi in a similar price range are the Xiaomi 15 (standard version) and the POCO F7 Ultra. Both devices are equipped with the Snapdragon 8 Elite, which is intended for 2025 flagship models, making the choice a tough one. Therefore, in this article, I would like to compare these two models.

Compare the body designs of Xiaomi 15 vs POCO F7 Ultra side by side.

Xiaomi 15

POCO F7 Ultra

Let's first compare the rear of the devices.

The Xiaomi 15 features a smooth, rounded micro-curved aluminum frame design. The rear material is glass. It comes in four colors: Liquid Silver, White, Black, and Green. The design is generally simple, clean, and beautiful, but the Liquid Silver variant adds an edgy, liquid metal-like look. It’s a design that can appeal to a wide range of generations.

The camera bump of the Xiaomi 15 is a high-quality unit that houses the triple cameras under a single square piece of glass.

The POCO F7 Ultra, as a gaming smartphone brand within Xiaomi, showcases a design that reflects POCO's gaming focus. While POCO may be associated with affordable smartphones, this model is part of the F-series, which is a flagship within the POCO lineup. Therefore, the rear is made of glass, giving it a premium feel. While the Xiaomi 15 had a simple and beautiful design, the POCO F7 Ultra’s rear uses two-tone colors and incorporates geometric patterns, resulting in a bold and modern design. If you find the Xiaomi 15’s design lacking, the POCO F7 Ultra’s design might be more appealing.

The POCO F7 Ultra’s camera bump is a high-quality unit that also covers the triple cameras with a single circular piece of glass. However, the POCO F7 Ultra has more intricate parts and a more complex design compared to the Xiaomi 15.

Compare the Xiaomi 15 vs POCO F7 Ultra Body and Display at Actual Size

Let's compare the body and display side by side in actual size.

As you can see, the Xiaomi 15 is compact. While many Xiaomi smartphones feature a 6.67-inch display, the POCO F7 Ultra also follows this trend with a 6.67-inch display, but the Xiaomi 15 has a smaller 6.36-inch display. This makes the Xiaomi 15 a notably smaller phone for a Xiaomi device, and this is one of its key features.

In terms of weight, the Xiaomi 15 weighs 191 grams, while the POCO F7 Ultra weighs 212 grams. The Xiaomi 15 is 20 grams lighter, making it a more lightweight and compact device.

Both devices are equipped with the 2025 flagship Snapdragon 8 Elite chip, but flagship models tend to be larger in size. Therefore, the Xiaomi 15’s size is considered valuable in this context. However, it's worth noting that the Xiaomi 15 isn't the smallest smartphone on the market today. On our site, yourfones.net, you can compare the size of the Xiaomi 15 with other smartphones in actual size, so we recommend carefully considering that.

Both displays feature a 120Hz refresh rate and a maximum brightness of 3,200 nits, ensuring brightness. The POCO F7 Ultra has a higher resolution, allowing for beautiful display on the larger screen. When it comes to touch sampling rate, the Xiaomi 15 has a maximum of 300Hz, while the POCO F7 Ultra reaches 480Hz. Looking at the finer differences, the POCO F7 Ultra is more suited for gaming.

Compare Xiaomi 15 vs POCO F7 Ultra in a Specifications Chart

Let's compare the cameras.

Both devices feature a triple camera setup, including a main camera, ultra-wide, and telephoto lenses.

However, the Xiaomi 15 has a significant advantage due to its Leica co-developed camera system, which is designed with a strong emphasis on image quality. For example, the Xiaomi 15 uses 50MP for all cameras, ensuring minimal degradation of image quality even when the focal length (zoom) changes. Additionally, it uses Leica Summilux optical lenses. Although both devices feature Xiaomi’s proprietary Light Fusion image sensor series, the Xiaomi 15 is equipped with the 900 version, while the POCO F7 Ultra uses the 800 version. The sensor size in the Xiaomi 15 is also larger, leading to better image quality.

Both devices have a telephoto camera with a focal length of 60mm (approximately 2.5x zoom) and support 10cm macro shots. With in-sensor zoom, there should be little to no loss in image quality up to 5x zoom. The Xiaomi 15 is a smartphone known for its camera strength, so the 2.5x optical zoom might feel a bit lacking considering its camera prowess. On the other hand, the 2.5x optical zoom in the POCO F7 Ultra should be more than sufficient, as it is a gaming phone.

The Xiaomi 15 supports Dolby Vision video recording at all focal lengths, making it superior for content creation in general.

The POCO F7 Ultra, on the other hand, features the VisionBoost D7, a 12nm graphics-focused boost chipset, which allows for ultra-clear graphics, high frame rates, and dynamic visuals during gaming and video playback. Additionally, it includes the WildBoost Optimization 4.0 for integrated game control and the LiquidCool Technology 4.0 cooling system, making it packed with features specifically for gaming.

In terms of battery, there is not much difference, but the Xiaomi 15 has a video playback time of 25 hours, whereas the POCO F7 Ultra offers 15 hours. The Xiaomi 15 stands out with its significantly lower power consumption. Wired charging is supported at 90W for the Xiaomi 15 and 120W for the POCO F7 Ultra.

Both devices are IP68 rated for water and dust resistance, but neither supports Felica. The Xiaomi 15 supports eSIM, whereas the POCO F7 Ultra does not.

In the end, which is better, Xiaomi 15 vs POCO F7 Ultra?

Both smartphones are equipped with the Snapdragon 8 Elite processor, yet their differences are clear, making both models attractive options.

The Xiaomi 15 aims to be the ultimate smartphone. While many recent smartphones are becoming larger, the Xiaomi 15 stands out by being relatively lightweight and compact. It emphasizes the original mobility of smartphones while packing the 2025 flagship chipset, and the Leica-quality camera offers a high level of satisfaction. It’s a smartphone that condenses high performance into a portable form. The design is simple, clean, and beautiful, with a concept similar to the iPhone, making it appealing even to users who were considering an iPhone. However, there is also a higher-end model, the Xiaomi 15 Ultra. While the Xiaomi 15 is feature-packed across the board, it doesn’t have any particularly standout features and excels at handling everything efficiently.

The POCO F7 Ultra, on the other hand, is the ultimate gaming smartphone, equipped with a graphics-boosting chipset. However, it’s not just a "gaming device"—it also includes a 2.5x optical zoom and a modern design, making it a smartphone that satisfies not only gamers but also general users. The fact that it can usually be purchased at a lower price than the Xiaomi 15 is another advantage.

So, while both phones offer high performance, if camera quality is your priority, the Xiaomi 15 is the better choice. If you want a phone that excels in both gaming and photography, the POCO F7 Ultra would be the better pick.
