Wireless charging is the transfer of power from a power outlet to your device, without the need for a connecting cable. It involves a power transmitting pad or stand, and a receiver, which is usually built into the phone itself. When we said it was cable-free, it isn't quite, because the charging pad or stand will still need to be physically plugge...
Wireless charging is based on inductive charging, whereby power is created by passing an electrical current through two coils to create an electromagnetic field. When the receiving magnetic plate on the mobile device comes into contact with the transmitter - or at least within the specified range - the magnetic field generates an electrical current...
The main wireless standard is Qi (pronounced "chee"). Qi is a standard that has been developed by the Wireless Power Consortium (WPC) for inductive charging over distances of up to 40mm.

Mar 13, 2023 · The Qi standard defines how power is delivered wirelessly. It also ensures secure operation and interoperability between all Qi-certified devices. Random wireless charging technologies may follow Qi or other standards to provide reliable wireless charging for devices.
Once it’s exceeded and the receiving coil starts to get too hot, the battery protection circuitry automatically downshifts the power delivery rate until it cools off. So even if a Qi charger seems to boast a faster charge than its counterparts, it will self-regulate that speed by design and slow it to a nice, safe trickle.
