Wireless PowerShare turns the S24 Ultra into a reverse wireless charger. To use:

- Tap Wireless PowerShare
- Place a compatible Qi device on the back of the phone
Supported: Galaxy Buds series, Galaxy Watch series, and other Qi devices. The phone stops sharing automatically if battery drops below 30%.
Compatible Chargers
Any Qi-certified charger works. For 15W, use a 15W+ charger with a 25W+ USB-C adapter. The Samsung Wireless Charger Stand is reliable for desk use and allows phone use while charging.
Common Issues
Charging stops at 80% — Battery Protection mode is active. This is intentional. Disable in Settings > Battery if you need a full charge.
Slow charging — Verify your power adapter is 25W+. A 5W adapter limits all charging to 5W.
