Is the S25 Ultra worth it over the S24 Ultra?

If you want the brightest screen, the newest chip and longer software support, yes. If you already own an S24 Ultra, the camera and battery gains are small enough that upgrading is hard to justify.

Does the international version work on US carriers?

It works on GSM networks such as T-Mobile and AT&T, including 5G where bands match. It does not support CDMA networks, and Samsung's US warranty may not apply.

How is the battery life?

Most owners get through a full day of mixed use. Heavy gaming or long camera sessions will need a top-up, and charging speeds are slower than some rivals.

Does it come with an S Pen and charger?

The S Pen is built into the phone. Samsung does not include a charger in the box, so you need a USB-C charger separately.

How does it compare with the iPhone 16 Pro Max?

The S25 Ultra offers a larger screen, a built-in stylus and more zoom reach. The iPhone counters with tighter ecosystem integration and different video strengths.

Is 512GB enough storage?

For most people, yes. If you shoot lots of 8K video or keep a large photo library offline, the 1TB model gives more headroom.
