Samsung embraced artificial intelligence with its suite of Galaxy AI features. And while the new S25 Ultra is a bit faster, a little curvier and has a slightly bigger display than before, it’s clear the company’s primary focus was upgrading the software and machine learning capabilities of its top-spec flagship phone.

Samsung has shied away from wholesale hardware changes, with a new chip and an ultra-wide camera sensor that were needed. That’s allows for additive improvements with AI, performance and system software.

CR reviews the Samsung Galaxy S25, S25+, and S25 Ultra, noting that the phones offer only modest hardware upgrades and a whole host of new Galaxy AI features.

The Galaxy S25 Ultra is expensive, but it's also good at everything, even if its cameras and battery life can't quite beat some of the best alternatives
