    I own a XT720 rooted and CPU overclocked, just did that today.
    However for the last week or so I noticed something is eating up my battery life.

    When I go to sleep i leave my device with screen off and locked, when I first got it it would eat no battery life at all within but now with in 8 hours it chews up 20% of my battery life in the night.

    I keep sync turned off however I see this in the status bar once in a while, actually often, several times with in 30 min , I'm thinking this is what is eating up the batter.

    Sync: Update Started...
    Prefetch Image: Update Complete...

    Can anyone shine some light on this, or what app/service could be doing this?

    Thanks

    I'm not sure what app would do this, but one thing you can do is turn off mobile data while you sleep, and underclock with SetCPU when the screen is off. That should help a bit until you find the perp.

    I Would not overclock unless there is a program witch demands faster CPU Speeds

    @JunBringer
    I thought about that but I still want to find which app is the culprit.

    @GoldenBulletXD
    I overclocked to get better device performance, and to be honest it is really noticeable.
    It no longer studders, and the interface is more responsive, I can't go back now.
    The battery drainage problem started prior to that.

    @Z3US
    I have two running services which I suspect, SyncEngineService which I have no idea which app uses it and it looks like the Android sync service for gmail contacts, picasa... etc. But I keep this disabled.
    There is also the Ping Chat service, that might be responsible.
    We should compare installed apps.
    I just hope the culprit isn't the os being 2.1 for both of us.

    I've had the same situation with my DX over the passed few days. Though I thought I had, I still haven't pinned down what is draining my battery during the night.

    Thanks for the recommendation. I've been using that and love it but to no avail in this situation. It does alert me to apps which are freaking out, but doesn't much help with something which is just doing constant little things which is my theory as to what's happening.

    I also think it must be something I've downloaded recently, but I can't figure out what it is. I wish I could get a time stamp indicating when I downloaded / updated apps. That could be useful.

    Maybe use task killer to shut down ALL apps when you are going to bed/ not using your phone

    Dear
    Install advanced task killer application, this application automatically kills running applications when your phone is locked.

    Very bad advice. Pain killers might make a broken leg feel better, but it only masks the real problem while it gets worse.

    Find the problem first and then take a reasoned course of action, which may include the limited use of a task killer (read referenced article above).

    ^

    Totally agree with this. Here is a run down of a similar post I made on another topic.

    @barneystuta

    Thanks for the tools I will definitively try them out and see if I can catch the app that is responsible.

    I haven't found the app responsible yet but I do have a workaround. It's lame but it works. I changed my power profile to "Performance" and my charge was at 90% when I woke up. My guess is something is trying to get to the net and since wifi sleeps when using the Nighttime profile, it just keeps trying, killing the battery. With Performance wifi remains awake and the annoying app is able to do whatever it is trying to do.

    Somewhat counter intuitive but it's a band-aid.

    Where do I find this profile setting you speak of?
    I'm on Android 2.1

    @barneystuta
    Can not locate the app TrafficStats, could you tell me where i can grab it?

    On my DX it's: Settings/Battery Manager/Battery Mode. Looking at again, it doesn't kill wifi but stops syncing data.


    Lunatic59, thanks for the heads up on TrafficStats. I'll give it a try.

    Download SystemPanel from the app store. You can set up monitoring and get a graph of times when apps or processes are using a lot of CPU.

    Thanks YMark just bought the full version of the app, first impression of it is good seems very thorough and well designed, I like the application archive feature too.
    Started monitoring for 1 day, let you know how it goes.

    EDIT: Just to add to this last night my battery dropped from 90% to 50% this morning.
    Juiceplotter showed about 10% every 2 hours or so.
