The Mi 15 Ultra is the Ultra-tier variant of the Xiaomi 15 Ultra carried under the returned Mi prefix in some markets — same 1″ Sony LYT-900 sensor (one of the largest smartphone sensors ever), same Leica periscope tele, same Snapdragon 8 Elite. Important: cases for the identical Xiaomi 15 Ultra fit 1:1, both share the same body. Available styles: silicone cases with soft inner lining and precise camera cutout, polycarbonate hardcases for the slim look, faux-leather wallets with card slots, rugged outdoor cases with reinforced corners (drop protection typically 1 m, premium up to 2 m and outdoor-top up to 5 m), transparent clear cases (anti-yellowing) for the original design, and lanyard or crossbody cases with adjustable strap — ideal for festivals, travel and hands-free everyday use. Cases in many styles — silicone, faux-leather, transparent TPU, crossbody with lanyard — brand availability on request in store.
