Xiaomi has announced its 15 Ultra flagship phone at a launch event in China, where its going on sale starting at 6,499 yuan (around $893). The Android phone joins the companys Xiaomi 15 and 15 Pro, which went on sale there in October 2024. It is a mostly iterative upgrade on last years model, but the big change is the addition of a 200-megapixel periscope camera that the company says excels in low light. The 15 series, including the Ultra, is getting an international launch this Sunday, March 2nd, at Mobile World Congress in Barcelona. Exactly which markets it will go on sale in remains to be seen, but its a safe bet that this one wont be coming to the US.Xiaomis Ultra line has always been camera-centric, even more so than Samsung or Apples top models, and the 15 Ultra is no different. Like last years 14 Ultra, the quad rear camera is arrayed in an enormous circular module on the phones rear. Its designed to resemble photography partner Leicas dedicated camera hardware, right down to the two-tone silver and black finish, and compact Ultra corner logo found on one of the phones three versions. There are also simpler black or white models.Most of the exciting stuff is on the rear, but heres a look at the display anyway.

This is a shorter zoom than the 5x periscope on the 14 Ultra, but uses a larger sensor, faster aperture, and higher resolution, which Xiaomi says results in better light capture, bringing improvements in zoom photography, especially in lower light. Xiaomi even codenamed the phone Night God internally, so low light photography is clearly a focus this year.The other three rear sensors are all 50-megapixel, and are set up similarly to last years model, albeit with small variations. The most noteworthy change is to the main camera, which has dropped the variable aperture tech featured on the previous model in favor of a fixed but fast f/1.63.Thats a whole lot of camera.

Beyond a new red finish, not much has changed here either: the internal battery is a little larger at 2,000mAh (allowing this to double as a small power bank for the phone), and theres a new thumb rest, but the core camera controls remain the same: a shutter button, video button, zoom lever, and exposure dial.The camera kit really does make the phone look like a digital camera. Image: XiaomiBeyond the inevitable upgrade to the current-generation Snapdragon 8 Elite chipset, there are few other upgrades or design changes. The 6.73-inch display is again 1-120Hz but a little brighter at 3,200 nits peak HDR brightness. An IP68 rating returns, too. The 6,000mAh battery is significantly larger, but the 90W wired charging and 80W wireless speeds are unchanged. As with other recent Android flagships, theres still no sign of Qi2 adoption.I thought the 14 Ultra was last years best phone camera by some distance, and my colleague Allison called it a photography nerds dream, so Xiaomi has set itself a high bar to live up to. This was such a strong camera, its understandable that the company has kept changes to a minimum this time around. But were looking forward to finding out whether its one big upgrade, the periscope, will deliver.See More:
