GM announced that Cadillac will add wireless charging of smartphones in the 2015 model ATS sport sedan and coupe launching this fall. The wireless charging will be compatible with Powermat and other in-phone wireless charging technologies, therefore once inside the car, you place the smartphone on the mat and you don’t have to connect a cord to charge it.
Because people keep their smartphones with them all day and Bluetooth uses a lot of battery juice, wireless charging in cars is an ideal solution.
