my galaxy s6 (verizon) got the marshmallow update on April 1st, but got my s6 edge plus April 2, and am frustrated to check and not see any signs that it will receive the marshmallow update soon (in the next couple weeks).
The s6 just has too small of a battery from normal to heavy use. It does great on idle, but for me if I start using heavily I may get 9 hours. I keep hearing though that the s7 edge has a batttery designed for 16 hours of moderate to heavy use
especially with the tempered glass protectors, I personally prefer to pay $10-$25 for a tempered glass protector and have a little extra insurance that I might not crack my screen
I most definitely would want the edge because it has a bigger screen and bigger battery. though the edges are cool, I personally haven't found them to be a necessity
as far as I understand no it won't affect the phone. However, if you have problems and they ask, it might void your warranty by using a charger that is not the original.
From everything I have read for the normal s6 the marshmallow should come out sometime beginning to mid April. With S6 Edge Plus starting sometime in the net couple weeks.
I would recommend either the otterbox (I have used them for years and love them). The other great option my friends have and I have for my tablet is beetle defense. My favorite is still otterbox. Haven't had them ever break and have dropped my phones many times and they have been more than fine.
