The Samsung Galaxy S7 includes wireless charging built-in. This means you can simply set it on a wireless charger to get more power when you need it.
In addition to support for wireless charging, the really exciting feature is that you can use Fast Wireless Charging on the S7 and S7 Edge.
We don't know how fast this will charge the Galaxy S7 battery to full, but we've seen impressive speed on other phones that support similar technology and we certainly love charging without wires.
