The LED on the front of the case communicates battery and charging status.
| LED Colour / Pattern | Meaning |
|---|---|
| Green (solid, brief) | Case battery above 60% |
| Yellow (solid, brief) | Case battery between 30% and 60% |
| Red (solid, brief) | Case battery below 30% |
| Red (blinking) | Case battery critically low (below 5%) or charging error |
| Green (blinking) | Case is charging via USB-C or wireless |
| Red → Green → Blue (flashing) | Earbuds in pairing mode |
| No light | Case battery empty or earbuds not seated |
Note: The LED only lights up when the lid is opened or closed, or when the case is connected to a charger. It turns off after a few seconds to conserve power.
Charging the Earbuds in the Case
- Place the earbuds in the case: Align the earbuds with their respective slots (L in left, R in right). The magnets will pull them into place.
- Check alignment: The earbuds should sit flush. If they don’t, remove and reinsert.
- Close the lid: Charging begins automatically. The LED will flash the current case battery level.
- Charging time: Earbuds charge from 0% to 100% in about 1 hour inside the case.
- Quick charge: A 5-minute charge in the case provides approximately 1 hour of playback.
Important: Dirty charging contacts on the earbuds or inside the case can prevent charging. Clean them with a dry cotton swab.
Charging the Case (USB-C)
- Connect the cable: Plug the included USB-C cable into the charging port on the case.
- Connect to power: Plug the other end into a USB wall adapter (5V/1A recommended) or a computer USB port.
- LED status: The LED blinks green while charging and turns solid green briefly when fully charged.
- Charging time: A full charge takes about 1.5 hours for the case alone, or about 2 hours if the earbuds are also charging.
- Disconnect: Unplug when fully charged. There is no harm in leaving it plugged in, but unplugging saves energy.
Recommended charger: Use a standard 5W (5V/1A) USB-A or USB-C charger. Fast chargers (9V, 12V) will step down to 5V, so they are safe, but avoid unregulated cheap chargers.
Wireless Charging
The Galaxy Buds FE case supports Qi wireless charging.
- Place the case on a Qi-certified wireless charging pad. The coil is in the centre of the case bottom.
- Check alignment: The LED will blink green to indicate charging has started. If it doesn’t, reposition the case.
- Charging time: Wireless charging is slower than wired — expect about 3–4 hours for a full charge.
- Remove any thick case: If you use a protective cover on the Buds FE case, remove it before wireless charging, as it may block the coil.
Note: Wireless charging may not work through metal cases or thick silicone covers.
