It has the advantages but when it comes to pricing, it's a whole lot of differences. Same chipset used, the charging speeds goes to Poco F7 Ultra, the peak brightness between phones are similar, most features have built in both phones, same software, same os, a big camera advantage to Xiaomi 15 Ultra, leading to all rounder but costs $450 more than Poco F7 Ultra. When budget matters, Poco F7 Ultra takes the win here.
