The Samsung Galaxy S25 Ultra is the most advanced smartphone Samsung has ever made.

It’s a cutting-edge example of just how powerful phone tech can be.

It even has Bluetooth S Pen capabilities that the Galaxy S25 Ultra misses out on.

They’re both large, powerful, titanium phones with top-end specs and beautiful displays.

The Samsung Galaxy S24 Ultra released on January 24 2024.

Getting ahold of one should be easy enough for anyone willing to stomach the four-figure price tag.

It’s also in strong supply at third party retailers and carriers.

Any leftover design motifs from the Samsung Galaxy Note series like the bulging rails and squared corners are gone.

This gives the Galaxy S25 Ultra a bolder look and adds contrast to the phone’s rear panel.

Internally, the Galaxy S25 Ultra has a larger vapor chamber to facilitate better cooling.

Per ourSamsung Galaxy S25 Ultra review, this should result in better low-light performance.

Otherwise, this is the same great camera setup as you’d find on the Samsung Galaxy S24 Ultra.

OurSamsung Galaxy S24 Ultra reviewfound the phone’s cameras to be extremely consistent in their output of great-looking images.

Though it lacks the Personal Data Engine, the Samsung Galaxy S24 Ultra is otherwise similar to its successor.

Both phones come equipped with the same 12GB of RAM regardless of storage configuration.

Still, 12GB is more than enough for multitasking and AI tasks.

Despite these strong similarities, there are still a few differences to consider that may impact battery life.

That said, both the Galaxy S25 Ultra and Galaxy S24 Ultra perform well in the battery department.

Honestly, there’s not much in it.
