The development of smartphones does not stand still and technologies such as a wireless charger for a phone no longer looks like magic, but rather routine, because wireless charging for a phone is already supported by many smartphones, but they have a number of limitations and this hinders their development. The principle of operation is like a docking station, charging without wires occurs when electromagnetic induction begins to work. It seems that wireless charging for a phone or any other device with support for this technology is simply the transmission of electricity over the air. The application contains information about wireless battery charging technology, various international standards for charging without a wire, the device and the effectiveness of how a wireless charger develops it. Many battery charging manufacturers support the basic standard, which means that having one charging station can be used to charge the battery for Android or another device that supports this standard. Fast charging without a wire is feasible by technology, it depends on the power and current strength, but has a reduced charge efficiency. The application does not allow you to charge your smartphone and does not increase the charging speed, but provides information about the wireless charging technology for the device.
