According to a new report, wireless charging uses about 47% more energy than wired charging.
Although wireless charging is more convenient, you only need to pat the phone on the charging pad to charge it. However, tests conducted by OneZero and iFixit on Pixel 4 smartphones came up with some surprising numbers. Wireless charging requires about 21.01 Wh(watt-hours) of power to charge a phone from 0 to 100%.
For comparison, wired charging requires only 14.26 watt-hours (Wh) to fully charge the phone. This means that, while convenient, wireless charging does not consume more power to charge the phone and generates more heat.
But presumably it is true, after all, the energy conversion of unlimited charging will increase the useless work.
Wireless charging treasure power consumption is really fast, because wireless charging needs to output power is definitely larger than the wired, and then the power consumption is fast.
