Wireless connectivity is nearly identical between these two phones — both support 5G, Wi-Fi 7, NFC, and dual SIM, covering all the modern essentials. The X300 does pull ahead on Bluetooth 5.4 versus the Pura 80 Ultra's 5.2, a newer revision that brings improved connection efficiency and better handling of multiple simultaneous audio streams — a meaningful but incremental upgrade for users with modern Bluetooth peripherals. The X300 also steps up to USB 3.2 against the Pura 80 Ultra's USB 3.1, translating to faster wired data transfers when moving large files like videos to a computer.
The Pura 80 Ultra, however, holds two exclusive features that are genuinely impactful in the right context. Its emergency SOS via satellite capability allows distress signals to be sent without any cellular or Wi-Fi coverage — a potentially life-saving feature for travelers, hikers, or anyone venturing into remote areas. It also includes a barometer, useful for weather tracking and altitude sensing, which the X300 omits entirely. Both phones share a solid sensor array otherwise, including gyroscope, accelerometer, compass, IR sensor, and GPS with Galileo support.
The connectivity trade-off here is meaningful on both sides. The X300 offers incrementally newer short-range wireless and data transfer standards, while the Pura 80 Ultra adds safety-critical functionality that has no equivalent on the X300. For most urban users the gap will feel minor, but for those who spend time off-grid, the Pura 80 Ultra's satellite SOS alone tips the balance decisively in its favor within this group.
