Insane battery drain issue - need urgent assistance!

[campuscop2003]

I'm an iPhone guy completely lost trying to fix with my wife's Verizon Samsung Galaxy S-3. Her phone drains the battery insanely fast. I always half listen to her complain about it, then last weekend I had it charging off my fully charged, two week old mophie juicepack 6000mah and it killed it after being connected to hit for only an hour, two hours max and only charging from 10% to 43%. I have charged my Iphone 5, and ran my ipad for hours off that little box and have never had that happen. I then realized that shes not crazy. I checked the battery settings and it says the screen accounts for 80% of the battery use. But with knowing the screen is not on constantly that didn't make much sense to me. She frequently goes in and closes apps that are not in use to try to get through her workday without it dying. I used to have a droid incredible two or more years ago however have had iPhone since so I'm a little behind and rusty with this operating system. My iphone is a battery hog and often needs charged, but her galaxy is putting even my hog to shame!!

Any assistance will be greatly appreciated!

First things first, what is her screen brightness? Secondly, if you could post some screen shots of her battery stats it would greatly help. It seems something may be keeping the device awake.

I put the screen on auto brightness. It was at 100% but that change didn't seem to help much. I will get a screen shot as as soon as I can and post it.

The screen at 100% would account for quite a bit of the drain

agreed. However when it was attached to the mophie the screen was off. Seems to drain just sitting on the counter some days.

So many things can account for battery drain. It's often an app that's constantly doing something, even when it's not supposed to, which we might consider a rogue app. The battery stats screen would be helpful, but sometimes it isn't specific enough.

Consider turning off mobile data and wifi when not actively using it. The radios use power, and they also allow apps to automatically refresh by accessing the web, which also uses power. Turn off GPS as well--Google Location Services can locate you well enough, unless you're actually using the phone as a Nav device, in which case just turn on GPS when you need it.

Install Wake Lock Detector, let it sit for a few hours, then run it to see if there are any apps that are waking the phone up way too often to do stuff.

I guess my question would be how long has this been going on, and what apps were installed or updated around that time? Phones rarely start having battery drain issues by themselves. So you have to look at what's different, and what's changed. How it's been used, where it's being used, what apps are different. Things like that. The likely culprit is an app behaving badly.
