    We don't know how long it's been of the charger..take another screenshot of that.
    But for an hour and a half screen time, and still being at 74%, that's pretty good battery life.

    This. Also, just in case you're not, be aware that the 38% figure doesn't mean the screen has used 38% of your battery. It means that of everything that's using the battery, the screen used 38% of that total.

    Almost 8 hours at 45%, with 3 hours of screen on, is fine. That would translate to about 15 hours with close to 6 hours of screen on time (assuming battery drain is linear). I don't think anyone would complain about that performance. That big, beautiful screen uses a lot of power when it's on.

    5 1/2 hours of screen on? I think that's phenomenal. How much total time, and how much battery left?

    Whut is wrong with my phone? When i set it to auto brightness on the lowest setting with all power saving settings on, like reduced fps and no smart stay; it always drains AT LEAST 74% battery

    I get about 12 hours out off a full battery. No live background or anything draining

    You've given us nothing to go on. See the screen shots above? Show us the same screens for your phone when it gets down to about 25%. Also tap on the graph, and capture the screen that shows up. Post all 3 here, and we might be able to start diagnosing something.

    Do you have any "battery saving" or task manager apps installed? How frequently do you sync things like email, facebook, twitter, etc.? How many hours of screen on time during those 12 hours?

    As promised, more screenshots...

    (yes 5 hours is long, but the %number is at least 74% at whatever time (on the lowest brightning setting)

    Its just, I have this thing for half a year now, and it slowely turned me into a power saving *****. I got an auto task killer that kills tasks when i turn my screen off, but its set to safe (only non-system task killing) and i also hit the button loads of times a day

    I set my screen on the lowest auto brightness,
    i have all the android power saving options on
    no custom launcher
    no live background
    wifi gps and bluetooth turned off ofcourse

    Can you help me out?

    What that 74% is saying is that, of everything that's using battery (radios, cpu, apps, memory, screen, etc.) the screen is using 74% of the battery used. So you've used 90% of the battery, and the screen has used 74% of that 90%. Nothing else is using very much power at all. If you compare the battery graph with the screen on bar (in the middle image), you can easily see that the slope of the battery usage lines matches up with the screen on times.

    Unfortunately, I don't think there's a lot you can do here. The big screens on modern phones simply use a lot of power and, yes, 5 hours is a lot of screen on time. If this is typical use, and you can't plug in and charge during the day, your best options are going to be to get an extended battery, extra batteries and an external charger, or a portable battery pack that attaches to the back of your phone. Or if you're in a car a lot, get a 12 volt car charger.

    A couple of things, though: you say "lowest auto brightness," but I'm not sure what that means. You can manually set the brightness to very low levels, or you can select auto-brightness, but I'm not aware of any way to adjust the level of "auto." If you're using auto-brightness, turn that feature off and set the screen as dim as is comfortable to you.

    You also say WiFi is turned off, but the bar graph shows WiFi on for a lot of the period. If you're connected to WiFi, that's good. But if you're not actually using a WiFi connection, you want to make sure it's really off. Having WiFi on, searching for a connection, is a battery hog.

    Are you running any kind of battery saver app (other than the built-in option) or task manager app?

    In your PM to me, you asked about widgets or launchers. A launcher shouldn't make any difference. Widgets can, depending on what they're doing. If a widget is constantly syncing in the background (to check weather, or news, or your location, for example), the background sync can possibly use up a fair bit of battery. Try to set them so they don't sync more often than you really need them to. The same is true of apps like facebook, twitter, email, etc. Any app that's syncing in the background uses power, and the more often it syncs the more power it uses.

    But, as I said before, it really looks like screen on time is the culprit here.

    Well. I meant that i dont have it on when not using it (Ofcourse)
    Nope. I dont have any other savers, since i heard they drain even more.

    But how come other peoples display's drain 38% display and get 16 hours out of it

    Remember, the % of all battery use will add up to 100%. So the less the screen is on, the lower the percentage of battery used by the screen, and the higher the percentage used by other things. If you used your screen for only 3 hours during that period, instead of 5 hours, the percentage of battery left would be higher, and the percentage used by the screen would be lower. If you had screen on time of 1 to 2 hours, you'd get 16 hours of battery life, too.

    More screen on time = less total time on battery. More screen on time = a higher percentage of battery used by the screen.

    The Samsung Galaxy S3 has a manufacturer rated battery life of 11 hours talk time utilizing a 2,100 mAh Lithium-Ion battery. This phone should last you through the day even with heavy usage and has strong battery life compared to other top Smart Phones on the market.

    I can't see this very well, but is that your GPS icon on the task bar? If something is running the GPS all the time, that's a huge battery drain. GPS should only run when you need it, eg for navigation. Even most location services do not need the GPS.

    Lose task killer. Close apps after using them. Adjust screen brightness yourself. WiFi Gps a major battery burner. Turn them off. Phone in my locker...airplane mode or off. Close apps!

    Well I must say the battery of GSIII is one of the best Android handsets out there. I genuinely never had discharging problems even during the times of heavy usage. I'm very much satisfied with my battery life but one thing I hate the most is the drainage during the phone is idle.
    For instance if my phone is idle for around 1hour and 15 mins it drains around 8-9% which is very frustrating.
    I have an ipad which has amazing battery life and may be the best one, its battery hardly ever drops if it is idle. I guess the iPhone must have the same drainage system.

    I can't really tell from your screen captures, but it doesn't look like the phone was fully charged at the beginging of that period. The stats are pretty meaningless if so.

    Charge your battery to 100% (not 98, not 99) and then unplug it. That will reset the battery stats. Use the phone until the battery is down to 50% or less, and then take the same screen shots. Also, tap on the graph on the first screen, and do a screen capture of that, too. Post all three.

    Ok. So here is my screenshot. The phone remained off during sleep, for some hours, Dnt know whether once or twice such it lasted more than a day.

    What was your screen on time? The screen is responsible for 50% of your battery usage, which implies the screen is on a lot. It's a big, bright screen, and when it's on it uses a lot of power. That's true of all modern phones with big screens, and the only thing you can do about it is to turn down brightness.

    Aside from that, with a recharge cycle in the middle it's hard to tell for sure what is shown. Do what I said in post #22, and capture all THREE screen shots before plugging the phone in to recharge again.But you're showing 33 1/2 hours, and it looks like it died about half-way through, which would be almost 17 hours. You're never going to get better battery life than that, with the screen on a lot, unless you buy a larger aftermarket battery.
