Xiaomi Poco X7 Pro

January 2029 is the end of the X7 Pro's security patch window — four years from its January 2025 release, under Xiaomi's official commitment. Android version upgrades stop earlier, after three, taking it from the Android 15 it shipped with to Android 18. So the phone keeps receiving safety fixes until January 2029 even after it stops getting new Android versions, and that later date is the one that determines how long it stays safe to use.

Three Android version upgrades and four years of security patches from its January 2025 launch, officially published by Xiaomi. That is a meaningful step up from the two-and-three arrangement common on cheaper Poco and Redmi models, and it is one of the reasons the X7 Pro is the pick of the range — you are getting flagship-adjacent performance with a support window that justifies keeping the phone.

They target different buyers. The X7 Pro is the performance phone: a Dimensity 8400 Ultra, a 6,000mAh battery and 90W charging aimed at gamers and heavy users. The Redmi Note 15 Pro leans toward camera and refinement at a similar price. If you play demanding games or simply want the fastest phone for the money, the X7 Pro is the clearer choice; if you photograph more than you game, look at the Redmi.

Comfortably. The Dimensity 8400 Ultra was an upper-mid part at launch and remains quick — the meaningful difference against 2026 flagships shows up only in sustained heavy gaming and high-end computational photography. For everything else, including demanding titles at sensible settings, it does not feel like a phone you need to replace.
