Both cost a lot of money on day one, so before you pick either, it helps to know what you’ll get back later. That’s exactly what this Xiaomi 17 Ultra vs Galaxy S26 Ultra resale comparison is here to answer.

Why Does The Galaxy S26 Ultra Edge Ahead In This Resale Race?
Galaxy S26 Ultra Edge manages to take a lead in this Xiaomi 17 Ultra vs Galaxy S26 Ultra comparison, here’s how.
Samsung’s Name Still Carries More Weight
Galaxy phones have been around for over a decade, and that history builds trust. Buyers shopping second-hand feel safer picking a brand they already know, and that comfort is one reason the Xiaomi 17 Ultra vs Galaxy S26 Ultra resale gap tilts Samsung’s way.
The S Pen Adds Demand
Not every phone comes with a built-in stylus, and that one feature gives the Galaxy S26 Ultra an edge with a specific type of buyer, students and note-takers especially. A phone with a clear extra use case tends to hold demand a little longer.
Xiaomi Still Trades Presence For Price
Xiaomi phones already launch cheaper than Samsung’s, and that lower starting point leaves less room to fall in percentage terms too. Even so, the brand’s smaller after-sales network in some cities means slightly softer demand once a phone goes used, which nudges its resale number down just a little.
Both Phones Still Follow The Same Basic Rule
No matter the brand, buyers of used flagships expect a real discount off the launch price. That rule caps how high any phone’s retention can climb, and it explains why the Xiaomi 17 Ultra vs Galaxy S26 Ultra resale numbers, despite the gap, still land fairly close together.
