Choose Xiaomi 15 Ultra if…
- One of the best phone camera systems ever — especially the 200 MP periscope.
- 1-inch main sensor delivers genuinely DSLR-like depth.
- 90 W wired + 80 W wireless charging.
- Bright, high-resolution Dolby Vision display.
Choose Galaxy S25 Ultra if…
- The most versatile camera system on any phone — four useful focal lengths.
- Seven years of OS updates matches Apple for longevity.
- Gorilla Armor 2 glass is the most scratch- and glare-resistant around.
- Built-in S Pen still has no real equivalent elsewhere.
