There is only a slight water ripple under wireless high-power charging, which will not harm the mobile phone hardware, no security risks, and will not affect the charging function, please feel free to use.
You can adjust the position of the phone and wireless charger (right in the middle) to reduce this phenomenon. In addition, it is recommended that you turn off the screen of the phone when charging, and enjoy the faster charging speed. I hope my answer can help you.
