Android OS eating battery?

    I have the extended battery for the Droid 2 Global I bought from verizon when I first got the phone and I can last basically an entire day without worrying about the battery dying.

    However the last 3 days or so my battery has lasted less than 6 hours with minimal use and no widgets running..

    When I check the battery manager to see whats eating my battery it shows android OS 66% and display 8%... now whenever I used to use my phone android OS used to be further down and display was sucking most of my battery... Can anyone help me figure out why this is happening? Is it my battery? Does verizon replace extended batteries if I have a warranty for the phone? I wasn't offered a warranty for the EB.

    Someone help? I'm going on a trip soon and need my phone and I have no way to charge it for a while.

    EDIT: Also my phone has been running hot constantly and slow.

    I've never read of this happening before, just to rule out the battery have you used the stock battery to see if it still happens?

    Yes it is still happening with the SB as far as I can tell. The extended battery seems to be doing it worse though which is very weird. However it still is running very hot and slow with both batteries and the Android OS in battery manager is in the mid 60%s to low 70%s with display under 10% and the battery completely dying (extended) in a matter of 4 hours or so with the phone idle.

    Nope. I havent downloaded any apps the last few days. Don't run a TK or Anti Virus..
    Its been a normal few days with my phone thats why I dont understand why this is randomly happening. I'm afraid it could be the battery but if it was the battery why would the Android OS be spiking from 3-4% to 60+%?

    I've researched this and found a few threads here and there describing the same problem with other phones including the Droid X but no one seems to have a solution all of the threads die without getting anywhere..

    If your willing to wipe the phone then you can root before hand, and backup all your apps and whatever you want (just not system) then wipe the phone to see if that fixes the problem

    Are you suggesting rooting my phone? Because I really do not want to do that.. Is there a way to figure out if there is a program draining my phone?

    Edit: I turned off my phone took out the battery and let it charge for a bit then took the charger out and turned it on I got the White M then I got the Droid logo that moves and now it is frozen at the droid logo (the logo is still moving as if it was going to boot)..

    This is getting really frustrating/bad ><

    I don't think that would help.. and its kinda hard to tell what exactly he is telling me to do ><.

    I have had no problems with the settings I had. I could go a full school day or just a saturday without having to worry about my phone dying (why I purchased the extended battery because I couldn't do that with the stock). I could play some games, email, facebook, twitter, widgets all without worrying about it dying and charging it every night with out problems. In the last few days it goes from dead to 70% just by restarting the phone with the charger plugged in, the Android OS is at 70% in battery manager, and I'm getting a few hours out of my phone.

    I don't see how Juice Defender with help my problems.

    Please anyone else have some suggestions for me? I'm becoming desperate to get to the bottom of this?

    If you don't find n e thing n decide to root, it should be simple as there is a good tutorial sticky in the D2G section

    I've had the same problem in the past with my unrooted D2G. Android OS usually uses 2-3% of the battery, and I can get 20 hours out. When Android OS jumps to 50-70%, I get five hours.
    I noticed that Android OS jumps when I use wifi, or sometimes when I use YouTube. The solution for me was to turn the phone on and off. I've tried to find out what Android OS does, as opposed to Android System, but I've had no luck. Also, I'm not running a lot of programs on the phone besides the basic stuff.
    This is anecdotal. I wish I could be more specific.

    Try using the OS Monitor app from the market. In the settings of the app change it to show the highest running process at the top in decending order, (like you would on a windows box using task manager). This will help you see what process is running when its getting hot. Another helpful app is system panel which let's you keep a history of app usage and such. Heloful for diagnostics. I use both of these regularly. I had a problem with a system process called System/Bin.Mediaserver a while back.

    Juice Defender is a must have app ... whether you go with the free or donated version of the app... Like Wozzy said it kills your 3g while your screen is off .. stopping your phone from trying to connect to 3g if you are in a spotty area.

    I havent been on stock since practically day one of having my d2g .. so this next bit of advice might be a little off but i should hit somewhere in the ballpark ... Under settings .. go to the option for "battery manager" click on the words below the huge icon of your drained battery and it will give you options on what kind of battery profiles you can set .. hope that helps a little .. as for why android os is using up so much battery is beyond me .. i claim to be no genius on anything other than .. well .. nothing but sometimes my advice helps a little .. best advice i can give though .. follow what Wozzy says .. hes pretty smart and knows what hes doing!

    There is possibly an app you've installed that is hijacking resources. Remove anything you installed in the past 3-5 days. Android OS should always be one of the least used processes in the list. Sounds like a software conflict, which is why I suggest uninstalling anything new.

    Now people may get agitated over this suggestion, but I use Advanced Task Killer for one purpose only: To end all running apps when a problem shows up. If you do this a few times a day and notice that things seem to be running better, your problem definitely is a rogue app draining the system.

    Have you checked settings/apps/running services to see what is running. You can stop the process there. Don't use battery monitors, task killers, or memory managers, waste of resources.
