Xiaomi 15 Ultra reviews by real users Xiaomi 15 Ultra

I've been using the Xiaomi 15 Ultra for two months, and I chose it mainly for its cameras and premium-looking design. While it does deliver in certain areas, overall, the experience has been more frustrating than satisfying.

Design & Build Quality:
The phone feels solid and high-quality, but it’s bulky and quite heavy – definitely not the most ergonomic device.

Display:
The screen looks great in terms of colors and brightness, but the refresh rate often feels like 60Hz, even though it should be much smoother. It doesn’t deliver the fluid experience you’d expect from a flagship.

Performance:
Performance is surprisingly poor. It lags and freezes even in basic apps, and in more demanding ones, it gets worse. It doesn’t match the hype or its flagship price tag.

Camera:
Cameras are decent, with the main sensor and zoom standing out. However, portrait modes are underwhelming, the ultra-wide camera is disappointing, and the AI often ruins shots instead of improving them. Video recording is average at best.

Battery & Charging:
Battery life is bad – it barely lasts a normal day and often needs charging in the middle of the day. While fast charging works well, the phone heats up significantly during charging.

Software (HyperOS):
This is by far the weakest point. HyperOS is unstable, lacks proper support, and doesn't receive regular updates. Critical bugs remain unresolved, like broken NFC and wallet apps, frequent crashes or freezes, and no built-in way to report issues or contact support. Even simple features like a proper notification history are missing.

Would I recommend it?
Honestly, not really. Unless Xiaomi seriously improves the software side, this phone feels unfinished and not worthy of its flagship status.
