First, make sure there are no obstacles between the wireless charger and the phone, such as metal items and magnetic items.
Second, check whether the phone supports wireless charging and whether it uses a wireless charger compatible with the phone. It is also necessary to check whether the phone has a protective case or other case, which can sometimes hinder the wireless charging function. Finally, if the above measures have not solved the problem, it is recommended to a professional mobile phone repair shop or contact the mobile phone manufacturer customer service for consultation or maintenance.
