Should you buy the Xiaomi 15 Ultra?
The Xiaomi 15 Ultra suits buyers who put photography first. It offers a 1-inch main sensor, a 200 MP periscope lens and 4K video at 120 fps. It is a heavy phone, however, and the global battery is smaller than in China. Xiaomi has since released its successor, the Xiaomi 17 Ultra.
