Samsung Galaxy S3

Last year I decided to switch from Metro PCS to Sprint so that I could get a better phone and better service. I had been a Metro customer for about three years before I switched over to Sprint. My biggest problem was I could not do a lot with the phone that I had. Every time I would try to download a new app I would get the message that I did not have enough storage capacity for the download. This limited the things I could do with my phone. The solution was to switch to Sprint and with them I was able to purchase the Samsung Galaxy S3. I absolutely love this phone and I can do so much with it. The only problem I have is the battery dies super fast. The phone is dead more than it is alive. I'm wondering is it a common problem with this particular phone. Any advice?
