iFixit specialists disassembled the smart ring Samsung Galaxy Ring and came to a disappointing conclusion: the $400 device is beyond repair. During disassembly, it became clear that the battery cannot be replaced without fatally damaging the ring. And the disassembly process itself was not easy: in order to get to the electronic components, it was necessary to melt the epoxy coating and chip it with a toothpick.
iFixit experts said that all components are very tightly soldered to the device — so that it is impossible to replace any of them. Inside was a Nordic Semiconductor nRF5340 SoC with two Arm Cortex-M33 cores, 512 KB of RAM and 1 MB of built-in memory, Bluetooth 5.4 and NFC modules; a battery, a tiny wireless charging coil, and an antenna to transmit the signal between the ring and the smartphone.
Since the battery cannot be replaced, the Samsung Galaxy Ring 's lifespan is unlikely to exceed two years, iFixit said. That's how long such a battery can last until it is completely discharged. Apparently, Samsung considers a two-year service life to be quite sufficient given the current pace of updating mobile devices.
