The Galaxy S21 series is Samsung’s latest flagship product launched in January. This is an advanced smartphone that can provide first-class hardware and software, including an Exynos 2100 / Snapdragon 888 processor, a One UI 3.1 on top of Android 11 OS, iconic camera functions, etc.
What is Wireless PowerShare?
Samsung calls it the reverse wireless charging function of the Galaxy S21. This allows you to share the functionality of the Galaxy S21 with another device by placing it back-to-back with the device you want to charge. Most Qi-compatible devices can use this feature, so it is not limited to Samsung devices. You can wirelessly charge your iPhone as needed.
Remember, this is by no means faster than wireless charging. When the reference voltage is input, its power is 4.5W, which is half of the Qi wireless charger (usually 9-10W). Samsung’s fast-charging wireless charging has a rated power of 7.5W on the Wireless Charger Duo. Therefore, using Wireless PowerShare, you will get about 10% of the power using a Qi-enabled smartphone within 30 minutes. Therefore, this feature can be used for devices with smaller batteries, such as Galaxy Buds.
Steps:
1. From Settings, tap Battery and device care > Battery > Wireless power
sharing.
2. Tap the Battery limit and choose a percentage. Once the device you are charging has
reached this level of charge, wireless power-sharing automatically turns off.
3. Tap to turn on the charging feature.
4. With the phone face down, place the compatible device on the back of the phone
to charge. A notification sound or vibration occurs when charging begins.
For best results when using Wireless power-sharing, please note:
• Remove any accessories or cover before using the feature. Depending on the
type of accessory or cover, Wireless power-sharing may not work properly.
• The location of the wireless charging coil may vary by device, so you may need to
adjust the placement to make a connection. When charging starts, a notification
or vibration will occur, so the notification will help you know you’ve made a
connection.
• Call reception or data services may be affected, depending on your network
environment.
• Charging speed or efficiency can vary depending on device condition or
surrounding environment.
• Do not use headphones while charging with Wireless power-sharing.
