Hello, I just received my galaxy s3 not too soon ago. I've been using it for maybe three days now, but and have been noticing a few issues with the battery, and when comparative to my old I phone 4. I just took a three hour nap, and and the battery dropped by 7% in three hours. This is while power saving mode was enabled in the notification bar. I have wifi enabled, gps enabled (no apps requiring it however), and things that my Iphone also had available, and it would depend drop 0.5 to 1% every hour. Is this normal? I really hate to see my battery waste away like this. I calculated that when playing modern combat 4 , as intensive as it is, I would maybe get an hour to an hour 30 minutes off a 100% charge. Once again the question - is this normal? P. S. Loving android. Much better phone than apple garbage. Thanks!
