Patent applications can be an interesting source of information about future solutions of a given company. That is why many people look closely at patents obtained by Apple. One of them suggests that in the future MacBooks and iPads can be used as a wireless charger for iPhones. Does this solution make sense?
Some people negatively approach wireless charging solutions. They are primarily accused of limited efficiency. The problem is that part of the energy that is charged by the wireless charger is not transferred to the smartphone’s battery. In addition, some manufacturers decide to use fans in their chargers, which are designed to cool the phone being charged. So far, Apple has introduced wireless charging (compatible with the Qi standard) on three smartphones: iPhone 8, iPhone 8 Plus and iPhone X. However, engineers from Cupertino are still struggling with the AirPower wireless charger project. In principle, it is to be a mat that will allow you to charge 3 devices at the same time. Despite this, Apple employees responsible for the development of new products work intensively on innovative solutions in the field of wireless charging techniques.
Apple wants to charge iPhones using other devices
Induction charging works similar to telecommunications wireless systems. Only instead of data, energy is sent to charge the battery. Therefore, the whole consists of a transmitter, a transmitting antenna, a receiving antenna and a receiver. The transmitter is a source of electricity, while the role of antennas is played by induction coils. In turn, the receiver is connected to the battery. But Apple wants to take advantage of the fact that the same coils can be used for both transmission and reception. That’s why the patent entitled “Inductive charging between electronic devices” assumes that iPad tablets in addition to the receiver would also have a transmitter that would draw energy from the battery. In this way, new iPads could wirelessly charge iPhones. In practice, this solution would be used for emergency charging of smartphones.
Another idea included in the patent involves the installation of three induction coils on MacBook laptops. One of them would be under the touchpad and the other two would be on the sides. Such a solution would allow charging three devices at once (e.g. iPhone, Apple Watch smartwatch and AirPods). However, the user would not be able to use the laptop then. Well, unless you decide to watch the movie.
Do the solutions proposed by Apple make any sense? Users often get tired of searching for sockets. Therefore, the possibility of wireless charging your smartphone with a different device could be a practical solution. In addition, the patent assumes that a device charged with a cable could at the same time be used as a wireless charger for another device. However, we do not know when (and if) Apple will introduce a patented solution to its products.
