Frequently asked
Does the Xiaomi 15T Pro have a periscope zoom camera?
Yes. Unlike the standard 15T, the 15T Pro adds a 50MP periscope telephoto with 5x optical zoom, giving it noticeably better long-range photography.
Can the Xiaomi 15T Pro charge wirelessly?
Yes. The 15T Pro supports 90W wired and 50W wireless charging, whereas the cheaper 15T is wired-only.
Was the Xiaomi 17 Pro Max ever sold globally?
No. Xiaomi limited the international MWC 2026 launch to the standard Xiaomi 17 and the 17 Ultra; the Pro and Pro Max stayed exclusive to the Chinese market, so buyers elsewhere rely on gray-market imports.
How long does the Xiaomi 17 Pro Max get updates?
Under Xiaomi's 4-year OS / 6-year security policy for the 17 series, support runs through roughly September 2031 from its September 2025 China launch -- about 5 years remaining if bought in mid-2026.
