Help Battery drains in six hours

[jamilinzi]

Hi, my battery life on my s3 recently has become abysmal-- exponentially wise and worse. I installed wakelock detector, but I can't make much sense of it-- all of my apps have autosync turned off, so I'm unsure why they're still waking the phone up? Any advice would be helpful.

Here are some shots from today, when I barely used my phone. Right now I'm at 2 percent-- went down that much while trying to sign up for this forum and post.

I don't know very much about phones, so simple language would help me!

Thanks.

How old is the battery. Sometimes they just go bad.

I just got the phone over the summer, so it's pretty new!
