Thinking is the Enemy of Creativity. It's Self-Conscious, & Anything Self-Conscious is Lousy.
I have the HTC One M9, the phone may not have the best battery for gaming purposes but it will last an entire day if you aren't playing games on it for hours. So far, I'm loving this phone. I just got it a week ago and it's fast, lasts the day for the usage I need and has amazing sound quality. (Has wonderful speakers.
The camera is also really nice, not as good as the LG G4 but still pretty damn good.
