My wife and I ordered two of the standing, wireless Samsung fast chargers last night online. With the "always on" screen option on the new S7/Edge phones, it will be perfect.
For those who don't know, the "always on" lets you have a clock on the screen with some additional info such as battery, email notifications, calendar, etc. It's dim and it moves around so it's not in the same spot. Basically, it uses less battery to leave it on than to constantly push the home button to turn your screen on to see the time, etc. Since we have gotten the phones, I've seen it use about 2-3% of my battery power in the course of 17 hours. That's the time when I take it off the charger in the morning until I put it back on at night (5AM-10PM).
