    My battery these days has been decreasing quite a lot. I charge overnight so I have 100 in the morning. Here is what I do

    Morning
    10 minute read CNN check facebook, Instagram, train status

    1 hour of music via Shuttle Music Player while traveling.

    About 5 texts

    Most of the day the phone is in my pocket I don't even take it out. I get push notifications from Yahoo Mail throughout the day.

    Then some more texts
    Facebook browsing
    Instagram Browsing
    Web browsing
    Total about 20 minutes

    Another 1 hour of Music

    When I reach home at around 4 I have about 40 percent. Why?

    I turn off wi fi when I leave, my brightness is 75 %, everything off, no apps running in background

    My day starts at 5 :30 AM to 4 PM

    It would help if you posted screenshots of your battery stats, with the percent breakdown of usage by apps/services, details showing your total screen-on time, and the quality of the cell signal.

    Also, try removing your battery, laying it flat on a table, and trying to spin it. If it spins freely, it may be going bad, since it would be bulging from the middle (not a good sign).

    My battery too is draining very quickly. It was after a security update a few weeks ago. Anyone else been experiencing this since?

    Thanks

    If you post your battery stats , we can help you identify what's really wrong with your device.

    I am saying because If you don't post those stats , Everyone will give you same tips : Reduce brightness , turn off GPS when unnecessary etc. (silly tips)

    If you can't post screenshots, maybe you could just transcribe the text and numbers that you see on that screen.

    Almost 12 hours with 60% battery drain, I thought that was normal.

    For those posting battery stats, can you also post your screen on time and screen brightness?

    As garublador mentioned, it would help to know your total screen-on time. Tap the Screen listing, and it should give you those details. Average usage for the S4 should probably give you around 5-6 hrs of total screen-on time (others with an S4, please chime in if I'm wrong).

    I'm going to guess you were charging the battery at the time. Your battery percent went up 2% and your on screen time is incredible for only losing 1/3 of the battery. Nothing in your stats looks out of place. 4.5 hours of screen time is a lot so everything else will look pretty minor compared to how much battery the screen has used.

    Unless of course you haven't actually used the phone that much. Then it looks like something is keeping your screen on.

    Yeah, something seems a little off there. 4+ hours of screen-on time with 60+% battery left is very unusual for a phone, unless it's some kind of extended battery.

    Hey. The Samsung galaxy's have large screens that is why most of your battery is on the screen. Also the apps may look like they are inactive but a lot of them are still using data and have a cache still active. My battery was quick at going down but I downloaded and app called "advanced task killer free" this app closes the apps properly and ends caches that are not needed. Now my battery lasts a lot longer on a daily basis.

    Lol. That is how these threads go. As if knowing it's an S4 with heavy battery drain will lead to one solution (sometimes both posters and responders seem to think so).
    I think your silly example is a productive one. Screen 64% of the power and is set to 75% brightness. I'd suggest put it to auto (and maybe keep your screen timeout relatively low).... I'd think that would reduce usage quite a bit (which is not to say it is the only way to improve battery usage).

    Very decent battery life imo , It looks like there was a wakelock for about 1 hour duration , have you identified the source ?
    I think you will give much better battery life if you can fix that wakelock.That would bring awesome 4h screen time.

    I get around 4 hours screen-on time and 8-9 hours standby with brightness above 75% throughout sometimes 100% all the time (No task killers , No battery saver apps , No Anti-virus)

    Agree with Sanjay--you're on track for over 7 hours of screen-on time, which is excellent.

    A wakelock keeps an Android device awake in order to perform a task. There are full wakelocks and partial ones. Full wakelocks typically keep the screen on (like, for example, if you're watching a video), while partial wakelocks will awaken the device without activating the screen in order to perform a task (like Facebook checking for new posts or messages).

    I see..I don't think I have anything that does that on its own that I know of other than something that I caused the screen to activate

    Lots of apps and system processes execute wakelocks--they're generally normal, but with some apps, they can get out of hand. Apps like Wake lock Detector can show you what's keeping the device awake, but it doesn't work on KitKat, I think.
