• Wireless PowerShare is a new feature from Samsung that lets you charge a device (like earbuds, a smart watch, or another phone) wirelessly using a Samsung Galaxy S10.
• In order to use Wireless Powershare on a Galaxy S10, the second device you're looking to charge needs to support the common Qi wireless charging standard.
• You can turn on Wireless PowerShare from the Galaxy S10's quick settings and then align the two devices back-to-back so their charging coils are lined up.

It's rare that smartphones wow us with truly innovative features anymore, but Samsung's Galaxy S10 actually does just that. Wireless PowerShare turns your S10 into a wireless charger, making it able to charge other wireless devices with its considerable battery capacity.

Your Galaxy S10 can charge wireless earbuds, smartwatches, another Samsung phone… even an Apple iPhone.

5. Position the Galaxy S10 and the device you want to charge back-to-back, so the charging coils on the two devices are aligned with one another. You might need to experiment a little to find the right position to get the charging coils lined up properly.

6. As soon as the two devices are properly aligned, the Wireless PowerShare screen will briefly display the message "Charging," and then the screen will close. You should also see an indication on the other device that it is charging.

7. Leave the two devices to charge as long as needed. When you've charged the other device sufficiently, separate them. The Wireless PowerShare screen should reappear; tap "Cancel" to turn off wireless charging.

You can also charge your Galaxy S10 while using it to charge another device - plug the S10 into a USB charging cable, turn on Wireless PowerShare, and align the devices. In this "dual-charging" mode, you can use the Galaxy S10 to charge another device while actively charging the S10 at the same time.
