No Strings Attached
Gone are the days when you had to look for a socket to charge your phone or laptop.
Researchers have urbanized a wireless-power transfer (WPT) technology that can help charge mobile phones from a distance. Until now, all wireless-charging technologies have had technical hitches with the problem of short charging distance, mainly less than 10 cm, as well as charging surroundings in which the devices should be placed in a fixed position. However, not all smartphones can avail this feature yet. Below are the devices which are facilitated with this extensive feature.
Sony has also dived into the wireless-charging trend with the Sony Xperia Z3. The waterproof phone lasts more than 12 hours on a charge. You will need a Wireless Charging Cover (WCR14) to charge it on a plate though.
For the Google Nexus 6, Qi wireless charging technology is supported on the phone, and so there’s no need to buy an extra cover. Although the Nexus-specific wireless charger is no longer available for purchase, you can use any Qi wireless charger to juice it up.
Motorola’s new Droid Turbo comes with a built-in Qi wireless-charging support. It offers more than 9 hours of battery time. Its Qi wireless charger also stands upright; so you can still read the content on your phone while it is charging.
The WPC (Wireless Power Consortium) supports the Qi standard, which is at present used in most Android devices that can wirelessly charge in the market. The technology works by taking benefit of magnetic induction, which allows the power to transfer from a mat to a phone’s battery. Qi, which in Chinese means “air” or “spiritual energy flow,” was recognized in 2008 and it is presently dealing with almost 206 companies, including Microsoft, Samsung and Sony. All of the phones on this list use Qi technology, but that might change soon.
The concept of wireless charging no longer resides in the future; it’s an extensively used technique of juicing up your smartphone. All you need is a charging mat below your handset.
