    After surffering through Motorola's Bionic, this phone is fabulous. Battery life is great!

    How about using the built in one in the notification status bar?

    I just use it so it's right on my home screen rather than pulling down the notification bar. It's called Data ON-OFF

    No reason for apps like that anymore, not when its build into the phone.

    It's all personal preference. Every phone comes with a stock text, email, and contacts app, yet people still download those things from the play store.

    Yesterday when I plugged my phone in for the night my battery was at 34% and I had about 14hrs on it with moderate use . Every smart phone that I have owned I had a spare battery just in case.

    After 15 hours yesterday, I plug it in at bedtime with 24% remaining. Using Bluetooth, Slacker Radio, social media, and email throughout the day. Not too shabby.

    Right now I have 22hrs 39% battery left. I did the drain to 15 power off and fully charge trick and am noticing a difference.

    What app are you using to monitor the CPU status? Are you rooted? I'm wondering because over the past few days I've had something sucking the life out of my phone. I did a little bit of research and it may have something to do with a corrupt media file on my SD card that can't sync with the phone (I haven't formatted it yet since taking it out of my Droid 1).

    No, my wife's phone is not rooted as of now.

    You'll need two apps to diagnose. First is CPU Spy. The other is GSam Battery Monitor (previously Badass battery). Install both and then open CPU Spy and make sure it's recording your cpu states. Now just use your phone like normal for a bit and let those two apps run in the background collecting data.

    After a bit open up CPU Spy and see if your phone is going into deep sleep. You may have to hit the menu key, then refresh to get the current reading. Deep sleep should be the bottom slot. As long as you're going into deep sleep you should be good to go.

    If you have 0% deep sleep, you'll know you have issues with an app wakelock keeping your phone awake constantly. I'll make a quick note here: most phones can't enter deep sleep while charging, to my surprise, my wife's GS3 does. However, to be certain, I'd run this test with the phone UNPLUGGED from the charger.

    Moving on. If you've determined you're not deep sleeping, open up GSam and look at what's using your battery. Screen should be one of your highest offenders. Radio should add a bit as well. The highest will probably be app usage. Click on app usage and it will bring up a detailed view. Are those the normal apps you use? Does anything seem abnormally high?

    The bug you mention about the corrupt sd card will show under System (*wakelock*) and the process will be called mediaserver. Click on system to see this. If system is in the 1-5% range you're probably fine.

    The wakelock that I DID diagnose on her phone was caused by Google+ instant upload. For some reason it wasn't uploading pictures properly and was keeping the device awake the entire time. I had to manually force the picture uploads under the Google+ settings and all was good after that. Now it sleeps like a baby and pictures upload the way they should.

    Awesome, thanks for the great instructions. The media server issue is what had me Googling my fingers off yesterday, it was the second highest battery drain next to the screen. So something is up with that. I went into all of the accounts I have on my phone and turned off any photo syncing. I'll install these programs and see what they tell me, I hope it's nothing more than something goofy with my SD card though, which I suspect because I deleted and moved a whole bunch of things this weekend and I think that is when my probably started.

    Thanks again for the quick reply!

    Do you have an sd card in your phone? Or are you using the virtual sd on the internal storage?

    If the internal is corrupt, unfortunately your only option is to factory reset. If it's the sd card, then a simple reformat should do. However, if it continues to happen, your sd card is likely done.

    Oh yeah it's an external SD. I took it right out of my Droid 1 and put in in the S3, then while it was in the S3 I deleted and moved a bunch of crap around on it. I'll see if a reformat helps.

    Thanks!

    I did as sbenson had suggested. I charged the phone to 100% and installed those apps. I set the phone down b/c I had some stuff to do and just now looked at it. Is this what I should be seeing?

    More than likely, its not a corrupt file but a DRM protected file. It seems that DRM and ICS don't play nice together.
    Some reports have been from music that was downloaded from yahoo. Yahoo turned their DRM servers off. The phone will keep searching until it gets the permission it is looking for.
