How to Charge Samsung Galaxy Watch 4
The Galaxy Watch 4 uses wireless charging with the included magnetic charging puck. Simply place the watch face-up on the puck and it begins charging automatically.
Charging Steps
Getting the watch charging is straightforward.
- Connect the USB-C cable to the charging puck
- Plug into a USB wall adapter (5V/2A recommended) or computer USB port
- Place the watch face-up on the puck, centering the back of the watch over the charging surface
- The watch vibrates and displays a charging animation when properly aligned
- Battery percentage appears on screen during charging
Charging Time
Both models charge relatively quickly with the included charger.
-
40mm Model: Approximately 90 minutes for a full charge (0-100%)
-
44mm Model: Approximately 2 hours for a full charge (0-100%)
-
Quick Top-Up: 30 minutes of charging provides roughly 40% battery
Tips for Best Results
A few practices help ensure reliable charging and battery health.
-
Keep Contacts Clean: Wipe the charging puck and watch back occasionally to remove dust and debris.
-
Remove Metal Bands: Metal watch bands can sometimes interfere with charging. If charging is slow or intermittent, try removing the band.
-
Avoid Extreme Temperatures: Don't charge in very hot or cold environments. Mild warmth during charging is normal.
-
Partial Charges Are Fine: You don't need to reach 100% every time. Partial charging doesn't harm the battery.
Charging Routine
Most users charge while getting ready in the morning or during an evening break. The watch can be used during charging with limited functionality, though leaving it on the charger ensures a complete charge.
