Whilst Samsung didn’t choose to add wireless charging capabilities out of the box for the Galaxy S4, it does have the capability to be charged wirelessly if you purchase a Qi wireless charge pad and back cover for your S4.
There are already plenty of Qi charging pads available through various outlets, but there hasn’t been much talk of wireless Qi back covers that can be used with the S4.
Smartphones like the Nexus 4 already have the Qi wireless technology built in, but smartphones like the S4, which have removable covers, usually don’t have this feature built in to save cost for both the manufacturer and the consumer. This means that if you want to make use of wireless charging, you’ll have to buy a Qi certified back cover to replace the original plastic one on the S4.
If you can’t deal with wires any longer, you may want to check out a product listing on Mobile Fun, as they have recently put up a Galaxy S4 compatible Qi charging cover for pre-order. The cover comes in both black and white, and should be in stock in the coming months.
Right now Mobile Fun seem to be the first retailer to have listed a wireless charging option for the S4, but we’re bound to see more alternative products hit the market soon.
