Our take on the Galaxy S25 Ultra 512GB Gray Unlocked

The Galaxy S25 Ultra is Samsung's top flagship phone, built around a 6.9-inch LTPO AMOLED 2X display at 1440x3120 with a 1-120Hz adaptive refresh rate. The Snapdragon 8 Elite for Galaxy and 12GB of RAM make it one of the fastest Android phones you can buy, and this version pairs that with 512GB of storage. It suits people who want the biggest screen, the S Pen and the longest zoom lens Samsung sells, and who accept a large, heavy body. Against rivals like the iPhone 16 Pro Max and Pixel 9 Pro XL it wins on zoom reach and display size, while costing more than most and offering fewer meaningful changes over the S24 Ultra. This is a refurbished unit with a verified battery above 85% and a charging cable in the box.

Questions and answers

Is the Galaxy S25 Ultra worth it over the S24 Ultra?
Only if you want the newer chip, the slightly brighter screen and the refined edges. The camera hardware and battery are close to the S24 Ultra, so owners of that phone gain little.
How does it compare with the iPhone 16 Pro Max?
The S25 Ultra has a larger screen, the S Pen and longer optical zoom. The iPhone counters with a more compact body and smoother video. Both are top-tier flagships.
Is a refurbished unit with a battery above 85% a problem?
Battery health above 85% means it holds most of its original capacity, so expect somewhat shorter runtime than a new unit. The rest of the hardware is the same as a new S25 Ultra.
Does it support two lines?
Yes. It takes one physical SIM and one eSIM, and it is unlocked for use on major carriers.
What is in the box?
The phone and a charging cable. There is no wall charger, so you need your own USB-C power adapter.
How long will it get updates?
Samsung promises seven years of Android upgrades and security patches for the S25 series, counted from its 2025 launch.
