    Take it back and see if you can at least get a replacement battery.

    It all depends on what your doing. Yesterday I was shopping with the wife, surfing, watching videos, etc and I was 10 hours, today, stayed home, not much use and I'm at 12 hours with 45% remaining.

    Also, I just got my S3, so I'm fully charging the phone, then using it to full depletion, then fully charge, then fully depletion for about 5 or 6 cycles. That should help the battery life as well.
    Just as an FYI. You don't need to do that anymore. Once should be good enough to calibrate the phone. But L-ion batteries do not require priming or calibrating. The phone however, does.

    I'd say do this once every 6 months.

    No complaints with my battery. I can regularly get 4+ hours of screen-on time, while my Galaxy Nexus and One X were both only getting no more than 3.

    My battery life is terrible. I might have a defective battery or unit. I'm at 5h 28minutes and i'm at 26% charge. I have attached a pic of my battery info at 32%.

    I was having similar issues. The first day I got about 16 hours of battery life, but after installing apps, widgets, etc. I was barely getting 8 hours. I've since spent time playing with the settings to figure out how I can get back to 16+ hours of battery life. As others have suggested poor signal is a huge cause of battery loss, take advantage of Wifi where you can and turn off Mobile Network when you are connected to Wifi. I also found GPS to be sucking up quite a bit of power, in some cases apps can still use your cell signal to track your position. I went a step further and tried turning off autosync just to see what the difference would be, thinking I would have to manually refresh or sync emails. Sure enough after going to bed with 100% charge I woke up with about 98%. The weird thing I noticed was I still got emails, facebook notifications pushed to the phone, so I'm not entirely sure what the autosync actually does? The rest of the day I had moderate use (web, facebook, twitter, words with friends, a few calls, etc.) connected to Wifi majority of the time. The phone lasted all day and thru the next night. When I woke up it was down to about 10%. I realize I'm not going to get that kind of performance most of the time, but I think I found the settings that work for me and will optimize my battery performance.

    My suggestion before you wipe is take a couple days, try playing with the display settings, turning things on and off, figure out what you need and what you can do without and see how it affects battery life.

    Used 7 hours and it was down to %20? anyone else having terrible battery life?
    Not normal from what I've been reading. A suggestion

    Install https://play.google.com/store/apps/d...om.rootmetrics

    and this https://play.google.com/store/apps/d...android.telnet

    Keep an eye out on your network signal. It you are, as an example, indoors at work. And have crap signal the phone is going to continuously go. ARE YOU THERE? ARE YOU THERE? ARE YOU THERE? ARE YOU THERE? ARE YOU THERE? To try and reach the network. On some phone, depending on how its designed it it has a poor signal it may even boost the juice to the radio, again draining the battery faster.

    Or you may simply have a rogue app that is beating the crap out of your phone. In which case search the market and find one of a bagillion apps that will log CPU time that an app is using.

    Or nuke the site, and slowly start reinstalling apps until you find the offender.

    You guys really need to be posting your screen-on time screenshots along with this battery shots. Screen-on time is a much better snapshot of your usage.

    Just an FYI, you don't need to turn off mobile data when on wifi. If you look you'll see you no longer get the 4G LTE icons when connected to wifi as it disables mobile data automatically. Once you're off wifi it turns it back on to get a data connection.

    What are the chances I got a defective android that has very bad battery life because of the phone. (using two diff batteries). Could this be possible?

    When looking at your battery stats, just click on "Screen" and it will bring you through to the screen's stats.

    You are at 50% battery after 4 hours, which seems like horrible battery life, but look at your screen on time - 2 hours!!! Many people of that screen time or less over a full 12-14 hour day! In that sense, your battery life is not bad at all since screen usage is a huge battery drain.

    Seriously though, are you actually looking at your phone that much?!? If so, I am not sure what to say except turn your brightness down and buy a second backup battery. If not, then maybe something is turning your screen on inadvertently and that is leading to your horrible battery life. Problem is finding out which app that is - hopefully someone with more experience than I can help you there.

    BUT, first we need to know whether you are truly looking at your phone for 2 hours out of 4 (and what are you doing) or not. Are you?

    I just had a thought. What is your auto screen off time set at? another post around here was complaining that his screen would come on for every text message or email he received. If that is happening to you and your auto shut off time is very long, then maybe that could be at least partly responsible for your high screen time?

    When in the battery stats, touch screen... It will then show screen on time.

    Mines looking pretty awesome so far. This is with auto brightness off and brightness at max the entire time. Plus gps and sync on the entire time. Lastly, I had terrible cell reception all day as I was underground.

    I've also had disappointing battery life. I average about 8 hours before its dead. I'm not too concerned as I have backup batteries on order.
