Xiaomi 15 Ultra Review: Saying Goodbye to Correct but Boring

Zhongguancun Online 2025-03-20 10:01:50

It should be said, in these two years I haveXiaomi phonebecoming less and less interested. Although it has to be admitted that Xiaomi inXiaomi 13Afterward, it was as if the Ren and Du meridians were unblocked, and I suddenly understood the real needs of the users. However, upgrading step by step is indeed correct but boring; you know it's unlikely to go wrong, but you're also not likely to have any expectations for it.

However, Ultra is probably an exception, fromXiaomi 10from the Supreme Commemorative Edition, Ultra became the Xiaomi full seriesmobile phonethe only product in China that spares no expense on materials, the latestXiaomi 15 UltraNature is also like this; compared to the previous generation's 1-inch main camera plus three small base limping combination, this time Xiaomi, after deep reflection, stuffed in a Samsung HP9 as the telephoto lens, but it also caused ripples of varying sizes at different levels. However, the only thing that can be confirmed is that this time, it's really not so boring.

First, let's take a look at the images, in terms of hardware configurationXiaomi 15Ultra uses a combination of LYT900 main camera + IMX858 medium focus + HP9 telephoto + JN9 ultra-wide angle, all four lenses have large sensors and large apertures, and also adopt a shorter flange focal distance, higher-grade resin lenses, and one-to-one matching of lenses and sensors, all for the purpose of enhancing optical performance.

In terms of actual imaging performance, let's start with the most highly anticipated super-telephoto lens, which boasts a 200-megapixel ultra-high resolution, 4.3x zoom, equivalent focal length of 100mm, and a Samsung HP9 sensor size of 1/1.4 inches, with an F/2.6 large aperture, the light intake has significantly improved compared to the previous generation IMX858.

The biggest advantage of 200 million pixels is the ability to record richer image information, so even when the picture details are magnified several times, the details can still be clearly seen, making it very convenient for secondary cropping and providing photographers with more freedom in post-production creativity.

The telephoto of Xiaomi 15 Ultra has a very strong long-range capability, with building edges remaining clear at 10x, 30x, and even 60x, complementing blurry details through Xiaomi AISP.

However, it is worth noting that the telephoto lens of the Xiaomi 15 Ultra does not perform satisfactorily in terms of image stabilization, and you still need to have a steady hand when shooting.

LYT-900 main camera is quite familiar to everyone, and it is currently a lens with excellent optical quality. When taking daytime photos, it can create a shallower depth of field effect, giving a very noticeable sense of spatial depth during shooting.

This time, the camera UI is more concise compared to before, making it easier to use. Swiping up calls out more photo-taking functions, and clicking the arrow at the top of the camera interface leads to advanced settings. The operational logic is clearer, and there have been significant changes to the street photography page, with the fonts for various focal lengths now in red. Additionally, you can customize the shutter style, giving it a stronger camera feel. The viewfinder uses a gray line design, allowing you to see elements outside the frame during preview, which makes composition more convenient. It still requires some getting used to when using it for the first time.

The Xiaomi 15 Ultra still offers a brand new imaging kit, with the grip and shutter button adopting a detachable design, providing a stronger sense of control. Additionally, it supports IP54 level water resistance, and the battery capacity has been increased to 2000mAh.

Appearance: continue fine-tuning, considerable controversy

fromXiaomi 12S UltraFrom the start, the Ultra model established the design of a large circular lens module, which, although not stunning, at least would not be a mistake. However, this year, due to the emergence of large sensor telephoto lenses, things are a bit different.

When you stare at the rear camera like I do, you'll notice that the three lenses below are not symmetrically arranged. Although watching the teardown video can help us understand why it is so, as consumers, we don't have the obligation to understand the manufacturer, and such an asymmetrical arrangement just looks odd.

Apart from the rear camera, the color options for the back cover have also sparked some controversy. The Xiaomi 15 Ultra offers four color options, in addition to the standard black and white, there are also two dual-color options: silver-black and silver-green. The official term for this dual-color design is a tribute to the classic Leica cameras. The main point of contention lies in the proportion of the division on the back cover. As for whether this design is truly aesthetically pleasing, it's a matter of personal opinion.

In terms of the screen, the Xiaomi 15 Ultra features a full equal-depth slightly curved screen, with consistent curvature on all four sides, combined with FIAA wiring technology, effectivelycompressionborder width, achieving visually equal narrowness on all four sides and alignment with the screen's R corners, combining the elegant curves of a curved screen with the visual enjoyment of a flat screen.

The top design is simple and brisk, with the infrared function integrated into the camera deco, demonstrating the high level of integration brought about by advanced craftsmanship. Additionally, the overall center of gravity of the Xiaomi 15 Ultra is more centrally positioned, so it does not give a top-heavy feeling.

Performance: Image Priority, Inevitable Compromises

Performance is the weakness of the Xiaomi 15 Ultra, and its positioning as an imaging flagship means that the limited internal space must prioritize the camera module. This also leads to the infamous dual-layer motherboard design being used in the Xiaomi 15 Ultra. In terms of other hardware configurations, the Xiaomi 15 Ultra still maintains the level expected of a flagship, with the Snapdragon 8 Supreme + LPDDR5X + UFS 4.1 already being quite good. Let's see how they perform specifically.

To better understand the performance of the Xiaomi 15 Ultra, we used the mainstream game with a heavier load, "Honkai: Star Rail," to test the actual performance of the Xiaomi 15 Ultra.

In "Honkai: Star Rail," with high-quality graphics and 60 fps enabled, the Xiaomi 15 Ultra maintained an average frame rate of 46.5 fps during a 30-minute gameplay session. It was able to maintain near full frames for the first 6 minutes, then gradually decreased to around 40 fps. However, the decline was relatively smooth, and the subjective smoothness was not significantly affected.

However, after a 30-minute test, the body temperature of the Xiaomi 15 Ultra was quite high, reaching close to 50 degrees Celsius at the hottest point on the back cover, posing a risk of low-temperature burns with prolonged use. In comparison, the screen side performed relatively better, maintaining a temperature of around 43 degrees Celsius.

Endurance: the first echelon of flagship

Finally, let's talk about battery life. I believe many of you have noticed that in the title, I defined it as being in the top tier of flagships. The reason for such emphasis is that, in an era where battery capacity is skyrocketing, flagships are destined to fall behind mid-to-low-end products with larger internal spaces. That said, in terms of specs, the Xiaomi 15 Ultra's battery configuration is not bad, with a 6000mAh battery and 90W wired plus 80W wireless charging, which matches its competitors. So, what is the actual battery performance like? Let's take a look through practical testing.

Here we set the screen to WQHD+120Hz (adaptive), auto-brightness, standard performance mode, and test for 30 minutes respectively.wild racingautomatic, 90 minutesiQIYI60 minutes of Douyin, 30 minutes of Taobao, 30 minutes of Toutiao, 15 minutes of taking photos, 15 minutes of video recording (1080P 30fps), 30 minutesQQ Music(screen on)

Ultimately, after a 5-hour test, 66% of the battery life remained. With such performance, even with heavy use, the Xiaomi 15 Ultra can ensure a full day of use.

In terms of charging, the Xiaomi 15 Ultra can be charged to 32% in the first ten minutes, 82% in half an hour, and fully charged in 45 minutes.

In the end of the article, let's summarize. I am actually satisfied with the Xiaomi 15 Ultra. As a product that should be ultimate, the Xiaomi 15 Ultra no longer tries to maintain the correct yet boring feeling found in the standard version, but really goes all out on imaging, an area where flagships fiercely compete, ensuring that its strengths are indeed strong. Although there are still some details worth optimizing, such as stabilization, these flaws do not overshadow its merits. The Xiaomi 15 Ultra may not be the best flagship of the year, but it is sufficiently "attitudinal," and that's enough. After all, compared to always being correct but boring, we need something more lively, even if it occasionally makes mistakes.
