Across the core connectivity stack, these two phones are remarkably well matched. Both support 5G, Wi-Fi 7, NFC, identical download and upload speeds, dual physical SIM plus dual eSIM, and an identical sensor suite including GPS, gyroscope, barometer, accelerometer, and compass. For everyday wireless use, neither holds a structural advantage. Where differences do emerge, they are specific and worth unpacking.
The Magic V5 ships with Bluetooth 6.0 versus the S25 Ultra's Bluetooth 5.4. Bluetooth 6.0 introduces Channel Sounding for more precise distance measurement and improved connection reliability, representing a forward-looking advantage as compatible accessories proliferate. The S25 Ultra responds with a higher USB 3.2 spec compared to the Magic V5's USB 3.1, enabling faster wired data transfers — relevant for users who regularly move large files to a PC or external drive. The S25 Ultra also supports ANT+, a low-power protocol used by fitness equipment and sports sensors, which adds niche but genuine value for athletes using compatible gear.
The most impactful exclusive in this group, however, belongs to the S25 Ultra: an included stylus. For note-taking, annotation, and precision input on that large display, a built-in stylus is a meaningful productivity differentiator that the Magic V5 cannot match. Weighing everything, the Samsung Galaxy S25 Ultra takes a modest edge here — its stylus inclusion, ANT+ support, and faster USB version collectively outweigh the Magic V5's Bluetooth version lead for most users.
