Only the Samsung S6 Edge +, The Note 5 and now the S7 phones are capable of wireless charging. The S6 phones cannot wireless charge.
Do I know what I'm talking about? Yep, I sell wireless chargers for a living.
Does wireless charging make a difference? It seems to (I had an S6 and have never been able to fast charge my phone before).
I received my fast Wireless charger from Holland a couple of hours ago and still need to check it out properly but it seems to be charging extremely fast. The app Ampere (by Braintapp) that I rely on just rolled over and waved it's little legs in the air, so I guess the app developer doesn't have an S7 yet and his app is now unreliable, which is most irritating..
