Nokia Explains Lumia Phones Wireless Charging




Nokia’s new Windows Phone 8 handsets will arrive on shelves with some highly appealing features packed inside, including support for wireless charging.

The upcoming Nokia Lumia 920 and Lumia 820 are the first devices from the company to provide users with support for wireless charging, which should make the use of the phone far easier than before. “All you have to do is place your phone onto a Nokia Wireless Charging Plate, Nokia Wireless Charging Pillow by Fatboy, Nokia Wireless Charging Stand, or even the JBL PowerUp Wireless Charging Speaker for Nokia to begin the charging process,” the company explains in a blog post. For those out of the loop, we should note that wireless charging means that energy is transmitted through the air to an electrical device, so that it would be charged. When it comes to smartphones, the feature translates into being able to charge a device without having to plug the wire into it. From a user’s perspective, the process is very simple, yet it becomes quite complicated when the technology behind it is explained.

“A transmitter coil is positioned at the bottom (L1) and the receiver coil (L2) is situated at the top and these coils are embedded into different electrical devices. L1 would be the Nokia Wireless Charging Plate and L2 would be the Nokia Lumia 920, for example,” Nokia notes. “An alternating current in the transmitter coil generates a magnetic field, which induces a voltage in the receiver coil. This voltage is then used to charge up the device.” Nokia chose to go for the Qi (pronounced chi) standard with the wireless charging capabilities of its smartphones, as it is already used by over 100 different companies worldwide.

Moreover, the company partnered with various restaurants and coffee shops to provide Lumia users with the possibility to charge their phones while not at home. “Nokia already has partnerships with Coffee Bean and Tea Leaf and Virgin Atlantic that will allow users of Nokia’s upcoming Nokia Lumia 920 and Lumia 820 to charge up using table-top wireless charging stations,” the company explains. The standard charging solution is the Nokia Wireless Charging Plate, yet users can also choose to go for the Nokia Wireless Charging Pillow by Fatboy or for the Nokia Wireless Charging Stand. Additionally, there is the JBL PowerUp Wireless Charging Speaker for Nokia that can be used when listening to music.
