New Smartphone Charging Techniques
Smartphones have transformed our lives and have become an inseparable part of our lives. As the whole world is going into the new phase of technological performance, our needs have become more sophisticated. On the one hand, we need speed and quality, and we need effectiveness on the other hand. Smartphone is that smart solution, small enough to be carried in a pocket. But, what if your gadget is dying out of battery and there is no outlet nearby? And what if you can borrow some battery from your friend? Sometimes we just need 5 to 10% battery to make an urgent call or send an important message.
Have you ever wondered how amazing it would be if your friend’s phone’s Wi-Fi hotspot could transfer the battery power like it transfers data to your device? Here’s the future of charging technology on your device.
We all know that our phones can be charged by plugging in a charger into an outlet. But, technology has given us another reason to be astounded as it has come up with a whole new idea of charging a handset from another handset.
There are two ways we can do that – wireless or through a cable.
Wireless charging is the transfer of power from one device to another without using a connecting cable. For wireless transfer, your device must have a power transmitting pad and a receiver. It is based on inductive charging, wherein the power is created by passing an electrical current through two coils to create an electromagnetic field.
Wireless charging works in accordance with some standards. Qi is one such standard developed by the Wireless Power Consortium (WPC) for inductive charging over distances of up to 40mm. Qi wireless charging has been adopted by many of the major smartphone manufacturers: Apple, Samsung, HTC, Huawei, Nokia, Sony, LG, Motorola and Blackberry.
Another standard is PMA, or Power-mat, which is comparatively less recognized. In 2014 PMA signed a deal with another wireless charging consortium Alliance for Wireless Power (A4WP) which will lead to the evolution of wireless charging at a much faster rate.
