I was very fortunate to be given the s6 edge as a gift 3 weeks ago.
I had a Samsung j5 and I loved that .but wow! I adore my edge.
Id heard grumblings about battery consumption but I just did what ive always done on any device turn off Wi-Fi, location etc when not needed.
I think I was lucky as the day I got it Marshmallow was rolling out and that has really helped re: battery issues. This is such a great device beautifully designed and great to use.
There Is only one thing id like an opinon on Ive read some reviews warning against using the fast charging it seems it has caused some performance issues. Three weeks in and I can honestly say this is the best phone Ive ever had.
