First, you need to check if your phone supports wireless charging. If supported, you will need to place the phone on the charging mat and make sure there are no obstructions between the phone and the charging mat, such as phone cases or metal objects.
Also, you need to verify that the charging pad is plugged in and in working order. If the above problems have been eliminated, you can try to replace the phone or replace the charging pad to test. If the problem persists, it is recommended that you contact the relevant after-sales service for help.
