I finally caved and did a factory reset. It makes a world of difference. Battery life is much improved, and I still have the benefits of the Jelly Bean upgrade. A little bit of a pain, but it fixed all of my battery problems.

Hey guys. I am new to the forums and really need help. I just got my Galaxy S3 two days ago from a Verizon store. I love it, except the battery life is horrendous. I have done many things to try to conserve it like disabling features and downloading juice defender. The battery life was much better since, but it is still bad compared to my old iPhone. I get7 hours and 13 minutes on battery with 9 percent left. My screen time on is 4 hours and 22 minutes at 9 percent. My display is using 43 percent of power, the Android OS is using 17 percent, and the internet is using 9 percent. Is my battery/phone defective? What do I do? Thank you!

Over 4hrs of screen on time is pretty damn good for the Galaxy S3! I wouldn't complain too much about that. What was your screen brightness set to?

Well basically my phone today died at 3 PM. It's 4 hours of screen on time then like 3 more hours of standby then it's dead. My brightness is set to about 25 percent. Using juice defender pro.

That's still pretty good. You may wanna invest in an extended battery or carry your charger w/ you if you use your phone that much. You can probably do a lot better than that w/ an extended battery. Have you thought about rooting & installing another kernel that will allow you to undervolt your device. That's what I do. It has seemed to help my battery out a pretty good bit.

That's actually really good and I would be happy with that.
