I've been using a Samsung Fast Charge wireless charger with my Samsung Galaxy S8 for a while now, and really love the convenience of it.
After using the wireless charger for several months, all of a sudden, one day it stopped working …
I put my phone down on the wireless charger and it would start charging for a few seconds and then stop with the message “paused” on the screen. This cycle would repeat endlessly and the phone would never charge.
Here is what worked for me.
Place the phone onto the wireless charger and move it up and down over the charger. Take it off the charger and repeat several times. Now check if the ‘paused' issue has been resolved.
Here's a video I found which explains the fix in more detail.
If this fixes the Wireless Charging Paused issue for you, let me know in the comments below. Or if you have found any other solutions that work, feel free to post them below.
