The mobile phone case will affect the wireless charging efficiency of the mobile phone.
Qi wireless charging has requirements for charging distance, and the maximum charging distance is only 10 mm. This is a bit \"blocking\" for Chinese mobile phone users who like to use mobile phone cases, although there is no need to remove the mobile phone case, the thickness of the mobile phone case has requirements, and some charging plates are marked, and the thickness of the protective case should not exceed 3 mm.
Since most smartphones that support wireless charging use Qi wireless charging standard technology. The technology uses electromagnetic induction technology to convert current into electromagnetic, and the phone charges by converting electromagnetic into current through a built-in coil. However, the drawback of this technology is that it will heat up the device, so the use of wireless chargers for mobile phones with phone cases affects their heat dissipation.

Wired charging: Wearing a phone case will not affect charging, if the ambient temperature is high, it may affect heat dissipation, at this time you can take off the phone case and charge;
Wireless charging: the standard protective shell of the mobile phone has no effect on wireless charging. If other protective shells are used, it is recommended to remove the protective shell and then wireless charging the mobile phone.
The use of mobile phone case may lead to wireless charging heat, so when they use wireless charging it is recommended to remove the mobile phone case and then wireless charging, they think it may block a signal of wireless charging, but the heat is also a consideration, so I think this wireless charging mode is a little redundant, it is better to use the power cord to charge directly.
