Reputable accent brings Qi wi-fi charging to the Galaxy S4, at the price of additional girth
Wi-fi charging is a type of options that looks as if an unimportant luxurious except you have got used it for your self. The power to put your telephone down on a magical pad and have it cost throughout the ether can trade the way in which you employ your tool. Unexpectedly, you might be free from wires and do not having to fret about consistent plugging and unplugging. It can be an delivered comfort if you are sat working at a desk all day, and even if you wish to cost your telephone on a nightstand with out getting tangled in wires.
The Samsung Galaxy S4 doesn’t include wireless charging capabilities out of the box, but the official S Charger kit brings Qi-standard inductive charging to the device, in the form of a replacement back cover and charging plate. In exchange for a little extra thickness on the phone, this lets you take advantage of wireless charging on your S4. So let’s take a closer look — we’ve got video, photos and more words after the break!
The Samsung Galaxy S4 S-Charger kit comes in two parts. The first, a replacement back cover for the phone, houses all the components necessary to let the phone use inductive charging. Gold contacts connect to the interior of the S4, and the cover sturdily snaps into place with a few reassuring clicks. The first thing you’ll probably notice about the wireless charging cover is the extra heft it brings to the Galaxy S4. It adds a few extra millimeters to the back of the device, and a small amount of additional weight, too. Looking at the LED flash — now recessed away from the surface of the back cover — gives you an idea of how much extra thickness it adds.
It’s not a trivial amount of extra thickness, and the differences are more than cosmetic. The S4 becomes more rounded with the new back cover, which might change the way you hold it. (In our opinion, this actually makes it a little easier to hold.) Finally, in case you were wondering, NFC still works even with the thicker back cover in place, although any form-fitting cases you might have bought likely won’t fit with the wireless charging back in plate.
The 2nd a part of the equipment is the respectable Samsung charging plate, which because the title suggests is a small, curved slab onto whick the cellphone sits. Its edges are curved upwards and the highest is matte textured to prevent issues slipping off, the perimeters are vibrant plastic, and the bottom is rubberized to carry it in situation. As soon as it’s plugged in, it’s only a case of putting the telephone on the pad and it’ll begin charging mechanically — you’ll be able to get a bit of popup message telling you that the cellphone’s charging wirelessly, and an LED on the plate will illuminate.
The Galaxy S4 prices wirelessly at 650mA, which is lovely cheap. To position that in standpoint, charging over USB 2.zero from a pc gives you 500mA, and most AC chargers will cost at 1A. The Galaxy S4’s wall charger if truth be told fees at a full two amps — in order that’s nonetheless going to be your very best wager for a quick cost. That stated, the primary advantage of wi-fi charging is comfort, now not pace.
As it is in keeping with the Qi wi-fi charging same old, which means that the charging again will have to work with present Qi charging pads, and the pad must work with Qi-compliant telephones (we efficiently examined ours with a Nexus four.)
The underside line is that you simply’re buying and selling further thickness for the benefit of wi-fi charging, and whether or not that’s value it to you goes to rely on how you utilize the telephone, and the way essential the skinny, graceful design is. We’ll maintain the usage of the S-Charger package as our primary manner of juicing up the Galaxy S4, and we will replace this text with any lengthy-time period impressions.
