Wireless charging consumes 47% more power

Although wireless charging is convenient, it also has some disadvantages. In addition to being slower than wired (but it is already fast now), according to a new report, wireless charging is about more than wired charging. It consumes 47% of energy.

OneZero and iFixit calculated that compared with traditional wired charging, wireless charging consumes more energy and generates more heat .

Although wireless charging is more convenient, you only need to tap the phone on the charging pad to charge it. However, OneZero and iFixit’s tests on Pixel 4 smartphones gave some surprising numbers. Wireless charging requires approximately 21.01 Wh (watt hour) of power to charge the phone from 0 to 100%.

In contrast, wired charging only requires 14.26 watt-hours (Wh) to fully charge the phone. This means that although convenient, wireless charging has to consume more power to charge the phone, and it generates more heat.

In addition, IT House learned that even if there is no mobile phone charging, the wireless charger will consume a certain amount of power. Moreover, if the position of the mobile phone on the wireless charging pad is not aligned, more power will be consumed.

Smart phone OEM manufacturers like Google and Apple can add a feature to their phones. If the phones are not aligned, wireless charging will be prohibited, which will greatly reduce power waste.
