Expert Review Summary

Expert Rating:

8.6/10

by Deepak Dhingra , 19 Mar 2025

Editor-in-Chief with 25+ years in tech, reviewed 1000+ gadgets.

Verdict

The Galaxy S25 Ultra builds upon the AI capabilities of its predecessor and comes across as a more refined and polished flagship. It doesn`t break the mould and seems like an incremental upgrade, but that doesn`t take away anything from the fact that the S25 Ultra is still the most loaded Android flagship money can buy, delivering on everything from performance, camera, battery life, software and more. The S Pen and the ecosystem features remain notable highlights.

Pros

Excellent display
Solid performance & battery life
AI & software features
Lighter than before

Cons

S Pen misses out on Air Actions
Pricey
Incremental upgrade over predecessor
