Yesterday I published an article that sums up my early thoughts on Samsung's shiny new Galaxy S7 and GS7 edge smartphones. I spent some hands-on time with the devices at a press event last week in New York City. During my briefing I asked a question that none of the Samsung product managers in attendance could answer:
Do the new GS7s support the latest 15w Qi wireless power standard?
The two new phones support both Qi and AirFuel Alliance wireless charging, the reps told me, and they also offer "wireless fast charging." But nobody knew if the GS7s support the Wireless Power Consortium's (WPC) latest specification, which was announced last June and allows for a maximum of 15w wireless charging.
This morning Samsung PR sent me an answer. "If the charger detects that the device supports fast charging … the output will be 15 watts," according to the company.
So the new GS7s apparently do support the latest 15w Qi wireless power specification. However, you still need to use a wireless charger that also supports 15w to get the fastest possible charge. Samsung announced a new Fast Charge Wireless Charging Stand [ Find it on Amazon – *What’s this?* ], but it doesn't appear to support 15w charging. The product page says the "new wireless charging stand allows you to charge your compatible Galaxy device up to 1.4x faster than standard wireless charging transmitters." The new charge pad appears to be a slightly modified version another Samsung wireless charger that was released in August, which support wireless power up to about 7w.
In other words, the new GS7 and GS7 edge [ find it on Amazon ] reportedly support 15w Qi wireless charging, but Samsung's wireless charging pads apparently do not. So you'll have to buy another 15w wireless charger, such as Incipio's $70 Ghost charge pad, if you want to get the faster wireless charge possible.
