Abstract
A method for performing wireless charging control of an electronic device and an associated apparatus are provided, where the method includes: determining at least one random value for controlling timing of packet transmission regarding at least one wireless charging report of the electronic device; and based on the aforementioned at least one random value, sending at least one random phase-delay packet, wherein each random phase-delay packet of the aforementioned at least one random phase-delay packet has a random phase-delay with respect to a time slot, and the aforementioned at least one random phase-delay packet is utilized for carrying information of the aforementioned at least one wireless charging report. More particularly, a wireless charging device (e.g. transmitter pad) is arranged to wirelessly charge the electronic device, and based on the aforementioned at least one random value, the electronic device does not obtain information from the wireless charging device through any packet.
