Bizon praises the S25's Galaxy AI update as "a monumental step change in how a smartphone works for you. The best way I can describe is is like a PA in your pocket, it's bringing together seamlessly all the apps on your phone so you can perform really complex tasks with super simple commands."

Probably the biggest hardware enhancement Samsung added to the Galaxy S25 Ultra is the latest and greatest in Snapdragon processing, the Snapdragon 8 Elite for Galaxy chipset. After a little bit of time using the phone, I can confirm everything feels very speedy and responsive.

The AI features on Samsung's Galaxy S25 phones uses both on-device and cloud-based AI models, including the touted AI assistant.
