What is reverse wireless charging on the Samsung S21?
Reverse wireless charging is a feature that allows the Samsung S21 to act as a wireless charging pad for other compatible devices. This means you can use your S21 to charge another phone, earbuds, or any other Qi-enabled device simply by placing it on the back of the S21. It essentially transforms your phone into a power bank, making it convenient in situations where you don’t have access to a traditional charger.
This feature relies on the same Qi wireless charging technology that is commonly used in many modern devices. When using reverse wireless charging, it’s important to ensure that the device you want to charge is compatible. Also, keep in mind that this feature may cause your S21’s battery to drain faster when it is in use, especially if you are charging larger devices.
How do I enable reverse wireless charging on my Samsung S21?
To enable reverse wireless charging on your Samsung S21, you need to access the Settings menu on your device. Navigate to the “Battery and device care” section, then select “Battery.” From there, scroll down to find the option that says “Wireless PowerShare.” Turn this feature on to start charging other devices. You will see an on-screen prompt reminding you to place the device to be charged on the back of your phone.
Once you have activated Wireless PowerShare, make sure the device you wish to charge is aligned correctly on the back of your S21.
