I have an Android phone that is a Samsung S21 Ultra. I also have an iPhone SE. When we went to El Salvador in January, I went to charge my iPhone with the cable I brought for that purpose. I plugged the one end into the phone and the other into a USB slot on a power plug. It didn’t work. After some trial and error we determined that the cable was bad. It was the only one I had with me and we did not have any way to go out and buy another.
It was then that I remembered reading about my new Samsung phone’s feature called Wireless Power Sharing. I couldn’t imagine ever needing that – but now I did! And it worked great.
Turn on Wireless Power Sharing on your Samsung phone
You can find Wireless Power Sharing as an option on your device’s shortcuts. Swipe down from the top of the screen, then swipe down again. There may be several screenfuls of shortcuts so you may need to swipe left before you see it. Just tap it to see the On button.
If you don’t see the shortcut, you can open the phone’s system settings, choose Battery and device care, then tap on Battery and scroll down till you see Wireless power sharing. Tap that and turn it on.
Not all Samsung phones have this feature, but most of them in the last couple of years do. It can’t hurt to look.
Use the back of your phone like a wireless charging pad
Once you have turned on Wireless power sharing, the back of your phone acts just like a wireless charger. Simply place any other wireless charging capable device on the back of the phone in the center, and it will start charging. You will need to take off any case for this to work. The phone must be naked.
