Compare Mobile Phones Side-by-Side

The Huawei Mate Xs is the more distinctive device here, mainly because of that huge 8-inch display. If your priority is reading, multitasking, maps, documents, or anything that benefits from a tablet-like canvas, it offers something the vivo simply can’t match. The trade-off is that its 60Hz refresh rate, 8GB of RAM, and 4500mAh battery make it feel less convincing as an everyday performance-and-endurance package by current standards.

For most buyers, the vivo V31 Pro 5G looks like the safer and more practical pick. Its 120Hz display should feel noticeably smoother, the 12GB RAM gives it more breathing room, and the 5000mAh battery is the better fit for heavy daily use. It may not have the wow factor of the Mate Xs’ massive screen, but it is the phone I’d trust more as a main device. Choose the Huawei for the big-screen form factor; choose the vivo if you care more about smoothness, stamina, and day-to-day usability.
