The S6 is a gorgeous device and would be my dream phone if there wouldn't be 2 things bothering me:
Battery Life
If you think that isn't an issue, think again! I barely use my phone throughout the day; a handful of text messages and a phone call on most days. Still, I barely had enough battery life left to make it through the day. If I used the camera and other features such as navigation, I had to charge it mid-day ...
Fragility
I never drop my phones ... ever! Well, until this one time where it just slid out of the case from approximately 3ft, bounced off the upper right edge, bounced once more off the upper left edge and then fell flat on its back. The result: back spider-cracked and the 2 edges totally bumped.
I don't really like larger phones either but I switched back to the Note 4 which, after all this months still feels too big to me. If you ever come across a smaller device as nice and powerful as the S6 but more resistant against accidents, I am in! Drop me a line.
