Compare Mobile Phones Side-by-Side

The Huawei Mate Xs is the more unusual phone here, and its main reason to exist is obvious: that huge 8-inch display. If you want a phone that can open up into something much closer to a small tablet for reading, multitasking, maps, or media, the Samsung simply cannot offer the same kind of canvas.

For most people, though, the Galaxy S25 Slim looks like the easier phone to live with. Its 6.3-inch screen is far more pocket-friendly, the 120Hz refresh rate will make everyday scrolling and animations feel noticeably smoother, and the Qualcomm chip gives it a more reassuring performance profile than the Kirin-based Mate Xs. Both have 8GB of RAM and the same 4500mAh battery capacity, so the decision is less about memory or battery size and more about form factor and responsiveness.

Pick the Mate Xs if the folding, large-screen experience is the whole point. Otherwise, the Galaxy S25 Slim is the more practical and modern-feeling choice.
