Frequently asked

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.

What processor is in the Poco F8 Pro?

It runs the Qualcomm Snapdragon 8 Elite, a flagship-tier chipset.

How fast does it charge?

It supports 100W wired fast charging on its 6210mAh battery.
