When you put the Samsung S25 Ultra head-to-head with the Xiaomi 15 Ultra, it’s no wonder Samsung’s sales are struggling [lol].

Here’s some friendly advice for Samsung: 1) Boost that battery capacity and deliver blazing-fast 100W charging, and 2) Rethink that sky-high price tag [facepalm]. These simple changes could actually win over some loyal fans.
I totally agree about the battery life on the S25 Ultra—it feels like it’s always running low. The Xiaomi 15 Ultra’s faster charging and better value might be hard for Samsung to ignore. Still, Samsung’s display quality is tough to beat, so they’ve got a strong selling point there. Maybe a mid-range option with these upgrades could really shake things up!
