I went from a razr maxx (I've always had motorolas) to a samsung galaxy s3. The s3 has some serious battery issues and everyone says it sounds like I'm under water when I talk on it. I really like the s3 but I'm within my 14 day trade in on it and am thinking either the razr hd or the note 2. Please tell me how the battery life is and any cons you have for the note 2. I read some reviews that say the back cover is very flimsy on it.
