The watch supports WPC-based fast wireless charging. Using the included USB-C magnetic puck and a 10W+ adapter, you can get from 0% to 45% in about 30 minutes. A full charge takes approximately 75–80 minutes.

The primary differences are the display size and battery capacity. The 43mm model features a 1.3-inch Super AMOLED screen and a 300mAh battery, whereas the 47mm model has a 1.5-inch screen and a 425mAh battery. All other internal specs, including the Exynos W930 processor and 2GB RAM, are identical.

For your repository, it is a mechanical necessity to note that the 43mm requires near-daily charging if you track intensive workouts or sleep with high-frequency monitoring.
