There are two types of smartphone users out there... Ones who can go a whole day without charging their phone and those who have to charge it a few times each day. The latter could be going away!
Apple has filed a patent for a phone that can be charge right through wifi.
The way the The "Wireless Charging and Communications Systems With Dual-Frequency Patch Antennas" work is actually quite simple according to AppleInsider:
Like conventional wireless charging techniques, Apple's design requires two devices —a transmitter and receiver —to function. Each device contains one or more antennas coupled to wireless circuitry capable of making phase and magnitude adjustments to transmitted and received signals. Such hardware can be employed in dynamic beam steering operations.
Please let this happen soon!!
