I had the Gear S2 for about a year then I dropped and broke the back glass....geek squad payed off. Got all my money back and bought the Gear S3 last week. I like it way more than the S2. I like that I can talk thru my S3 which I couldn't do with my S2 because it was Bluetooth only (my S3 is also Bluetooth only but have a mic and speaker). As for the battery life, it's pretty good. I have to charge it every third day with normal usage.
