Xiaomi's biggest-battery flagship -- a 7,500mAh silicon-carbon cell and a fully functional rear display -- but it's China-only, and its update clock, running to September 2031, is already ticking down.
Is the 17 Pro Max still supported?

Frequently asked questions
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.
How big is the battery really?
7,500mAh using silicon-carbon anode technology, which is very large for a phone this thin (8mm), and it charges at 100W wired or 50W wireless.
Xiaomi 17 Pro Max vs Redmi K90 Pro Max -- which has better longevity?
Both are China-only Snapdragon 8 Elite Gen 5 phones with similarly sized batteries, but the Xiaomi 17 Pro Max carries Xiaomi's explicit written 4/6-year update promise, while the Redmi K90 Pro Max's update timeline is estimated from track record rather than an official pledge.
