Don't have my S7 Edge yet, but from what I've read, Always On doesn't seem very useful for me. It uses about 1% battery per hour and only gives a tiny summary of the number of phone calls and messages. I do wear a watch, so I guess it does provide utility for someone who doesn't wear a watch, but I can just listen to my phone and hear emails or phone calls coming in. I might download AcDisplay and see if it works okay. I am kind of spoiled by having display info pop up on my Droid Turbo 2. There were some reports that AcDisplay uses a lot of battery. We'll see.
