How to charge Cell Phone Wireless
Some of the devices comes with inbuilt wireless charging feature,but now you there are many options for adding wireless charging to your high-end phone to low-end-phone,there are few options.
For a few years, every single high-end smartphone (with one notable, iPhone-shaped exception) came with wireless charging included in it. That seems to have changed.Now in the 2016 phones from Google, HTC, Motorola, Lenovo, Sony, and even the fan-favorite OnePlus lack both Qi and PMA charging. It seems Samsung is the only major player still interested in the feature.

* TRICK 1 :-

By Wireless Charging Phone Cases
iPhone fans were understandably miffed that their top-of-the-line gadgets didn’t have the        option. Third parties rushed to fill the consumer void, and the answer they came up with was a              phone case that combined basic protection with a wireless charging induction coil and an integrated      charging port attachment. Voila—wireless charging for iPhones.
Mophie is probably the best known of these gadgets, offering its Charge Force cases ($60 for iPhone 7 and 7 Plus) and Juice Pack Air with an integrated external battery ($100, iPhone 7 and 7 Plus). That doesn’t include a charging pad, but the company’s technology supports both Qi and PMA standards. It sells wireless cases for the Samsung Galaxy series too, but since those phones already support wireless charging, they only come with the external battery option. Mophie doesn’t support any other phone brands.
Mophie is pretty much the only game in town when it comes to major vendors. The big drawbacks to this approach are a high price tag and a bulky design. And, you might be able to find a much cheaper wireless charging case—for a much wider variety of smartphones.

By Wireless Charging Adapters
Stick-on adapters offer a more universal solution. Fed up with trying to match the ever-growing variety of phone designs with custom-fit cases, accessory providers have trimmed the fat and simply wrapped an induction coil in a plastic protective case, stuck on some glue, and added a USB charging port. It’s a flexible solution that needs only a few basic models to cover almost any phone.

The advantage to stick-on adapters is availability. They’re more slimmer enough to fit underneath the plastic of a standard, non-charging phone case. The only downside is a rather unsightly flat cable that needs to be unplugged if you want to use a conventional charging cable.
Sporting a low cost and compatibility with practically all phones and case combinations, these adapters are probably the best bet for most users.
