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. One of the reasons manufacturers are pushing wireless charging is that it can reduce the opening of the phone.
For example, with the popularity of Bluetooth wireless headphones, some smartphones have simply eliminated the \"headphone jack\" - because Bluetooth headphones solve the problem of unplugging traditional wired headphones.
Similarly, with the innovation of wireless charging technology, the frequency of use of mobile phone charging ports will soon be reduced, thereby reducing loss.
In addition to the mobile phone itself to support wireless charging, some high-end models, but also provide wireless \"backcharge\" function.
In simple terms, the phone can charge another low-battery phone, or help charge a smartwatch. In 2018, Huawei's Mate 20 Pro, in addition to supporting 15W wireless charging itself, can also \"reverse\" charge Android and iOS mobile phones that support wireless charging.
Yes, but charging with a phone case is not recommended.
Most mobile phones are used lithium batteries, wearing a mobile phone case charging, lithium batteries will heat, heat may lose the life of the battery, mobile phones may also be due to high temperature, resulting in crash or other adverse effects, loss of mobile phone life.
Yes, but not a metal case.
