The fastest wireless charging speed currently available is 100W, which is offered by Xiaomi’s 100W wireless charging technology. This technology is capable of charging a smartphone with a 4,000mAh battery from 0 to 100% in just 15 minutes. However, as of early 2022, there are no commercially available smartphones that support 100W wireless charging.
The fastest wireless charging speed that is currently widely available is 50W. Several smartphone manufacturers, including Xiaomi, Oppo, and Realme, offer smartphones that support 50W wireless charging. With 50W wireless charging, a 4,000mAh battery can be charged from 0 to 100% in around 40-45 minutes.
It’s worth noting that in order to achieve these fast charging speeds, both the charger and the device must support the high-speed charging technology. If your device does not support high-speed wireless charging, the charging speed will be limited to the maximum speed supported by your device. Additionally, fast charging may generate more heat than slower chargers, so it’s important to monitor the temperature of your device during charging to avoid overheating.
