Great device and excellent service! The Xiaomi 15 Ultra was delivered in perfect condition and impressed across the board. It was delivered within just two working days via FedEx - fast, reliable and free of charge. The price-performance ratio is excellent and I would buy the product again at any time. The customer support and overall service were also excellent. A very positive experience all round.

I recently bought a Xiaomi 15 Ultra from Back Market, and I couldn’t be happier with my purchase. The phone arrived in excellent condition — honestly, it looks and feels brand new. No scratches, dents, or signs of use at all. Everything works perfectly, and the performance has been amazing so far. The packaging was secure. This was my first time ordering from Back Market, and I was a bit unsure at first, but now I’m genuinely impressed with the quality and service.

Top device, had only 7 charge cycles in total so really as good as new. No scratches or damage. Only the box it was shipped in I don't think was original.

The Xiaomi 15 Ultra takes its place among flagship smartphones, boasting advanced imaging tech and robust performance. Released in early 2024, it arrives two generations ahead of the Xiaomi 13 series, blending premium hardware with pro-level camera features and a sleek design. If you want hardware muscle and creative versatility—even as newer models wander into the spotlight—the Xiaomi 15 Ultra's specifications remain relevant in 2025.

Key features:

Release Date: February 2024
Display: 6.73-inch LTPO AMOLED, QHD+ resolution, 120Hz refresh rate
Processor: Snapdragon 8 Gen 3
Camera: Quad rear setup with 50MP wide, 50MP periscope telephoto, 50MP telephoto, and 50MP ultra-wide (Leica partnership)
Operating System: Ships with Android 14 (HyperOS)
Connectivity: 5G compatible, Wi-Fi 7 support, Bluetooth 5.4
Build: Aluminium frame, curved display, Gorilla Glass Victus 2 front

Who is this for?

The Xiaomi 15 Ultra is best suited for mobile photographers, videographers, and power users who need photography flexibility and a responsive display in daily work or creative projects. It’s also a solid pick for those who want a flagship Android device without following the Apple crowd. Compared to rivals like the Samsung Galaxy S24 Ultra, it goes heavy on camera customisation but can be a touch bulky for minimalists.

Pros & Cons:

Pros	Cons
Outstanding camera system developed with Leica.	Larger size and weight may not suit those preferring compact phones.
Vivid QHD+ AMOLED display with 120Hz refresh rate.	Pre-installed software includes some bloatware you may want to tidy up.
Flagship Snapdragon 8 Gen 3 performance.	Not the most subtle design—the large rear camera housing stands out.
Strong build quality with Gorilla Glass Victus 2.	Not as widely supported with accessories as mainstream rivals.
