Only 1 day in, but learning to love it. In the hand at first, I wasn't so sure. It's heavy. My s6 active is a feather compared to this thing. Almost 20 hours, 8 with moderate usage, 55%. So, battery is a beast. My 6 was showing the age on its battery. Easily getting through a day still, but it was a 2 day cruise when it was new....
