This phone is still very fast, reliable, no lag or freezes, excellent camera and display. Also durable with no scratches or dents and I dont even use a case for it and dropped it a lot of times(never on concrete thankfully). Battery life is acceptable with 4 hours on screen time and 48 hours standby. I love how it gets fully charged in 80 minutes.
This phone has cured me from my phone buying addiction, my friends and family are shocked that I have the same phone for 9 months. They say the only reason for that must be that the phone is really good. And it definitely is. Love my S6.
