Welcome to the forums!
Please note that this post is in the wrong forum - this forum is intended for questions/comments regarding accessories (cases, batteries, etc) for the Verizon phone: this post belongs two levels up in the main S3 forum.
Anyway, since it's already here...
Are you using a 3rd party launcher?
What firmware is currently on your phone?
Did the problem start recently or has it always behaved this way?
As far as your battery life goes, rather than shutting the phone off completely, you can try putting it in Airplane mode - you should see a noticeable improvement by doing that.
