How to use Wireless PowerShare on the Galaxy S10

Last modified : Mar 06. 2019

The S10 allows device-to-device charging without the need for a charger. You can also charge your S10 and another device at the same time.

Optimised battery performance

The S10 features a much larger battery, giving it longer battery life and faster app launch.


The in-built machine intelligence learns your behaviour, so can automatically adapt to power-saving modes and restricts less frequently used apps to maintain power for longer.

If the battery on your device is getting low, automatically transfer power from your S10. Simply activate “Wireless PowerShare” on your notification panel, then place the other device on the centre of your S10 with their backs facing.

Please note: The location of the charging coil may vary by device model. You may need to adjust the devices until they connect with each other properly.

Please note: This is only available on S10 phones and other devices that support a wireless charging feature. If the battery level on your S10 drops below a certain level, Wireless PowerShare will automatically turn off.

Follow the below steps to activate dual charging:


Pull down the notification panel on your S10 and tap the Wireless PowerShare icon to switch it on.

2 Put the centre of the S10 back-to-back with another device.
3 The screen will confirm once the devices are connected. Tap “OK”.

If you pull down the notification panel again a message will show that it is charging the connected device. The green Wireless PowerShare icon will also appear on the display bar or on your Always On Display panel.

Please note: Depending on the type of accessories or phone covers being used, the Wireless PowerShare feature may not work properly. It is recommended to remove any accessories or phone covers before using Wireless PowerShare. Only devices that support wireless charging can be charged using this feature. The charging speed or efficiency may vary depending on the device’s condition or the surrounding environment.
