    It's 2 of them. One is named 'akmd' and the other is 'mediaserver'.

    They're CONSTANTLY using anywhere from 1 - 8% of my CPU processes and draining my battery incredibly fast! :(

    What the hell are these things and how do I turn them off? They never really showed up until a couple of days ago.

    I've uninstalled all of the apps I downloaded in the last 2 days, nothing changed.

    I've turned the phone off and on, nothing changed...

    I just don't know what to do...


    sn: i'm using these bad boys to monitor my phone...

    Mediaserver can be invoked from a number of different multimedia apps, and probably is responding to the configuration of one or more apps set to default.

    You'll have to go into each multimedia app's settings to find out which one(s) is/are providing unneeded service loops, draining your battery.

    Akmd is connected to the accelerometer and sometimes invokes when certain clock apps or other widgets are on the screen and get stuck running when the screen is turned from portrait to landscape or vice versa. You may have to start uninstalling or clearing data on various screen apps and/or widgets to figure out which one has set akmd into over activity.

    Well, the akmd process continues to run...still trying to find a solution for it.

    I went through my apps one by one and it seems that the mediaserver process is no longer killing my phone...

    But now a new one named 'suspend' has appeared. Between that and akmd my Evo loses 10% per hour while not in use :-/

    ...I just ran another diagnostic; I think 'mediaserver' and 'suspend' are tied together. When one shows the other does but they continue to take turns eating up my batt.

    Make a list of your apps and widgets. I'm wondering if you have a compass, for example, or other widget which is causing the akmd service to perpetuate.

    Here's a list of apps on my phone...I do have a compass...

    If I end up having to reset my phone will it still have 2.2 or will it revert back to 2.1?

    Damn, I'm giving up. I can't live with the impracticality of my phone needing to be constantly connected.

    So, fellas, how do I reset my Evo?

    Before doing a factory data reset, try going into application manager and clear cache and data on that task manager, then uninstall it, then reboot.

    Thanks for the suggestion, Frisco

    I cleared the cache, uninstalled watchdog, charged the battery to full and checked how much charge it lost after an hour of no use...

    Results:

    FULL CHARGE

    did a factory reset.

    just re-downloaded all of my apps except for the ones that "prevent phone from sleeping"...so far, so great.

    i fully charged the phone, unplugged it, and it's been 30 minutes and it's still at 100% charge.

    Here's the list of apps I didn't re-install:

    What I'm going to do is install them one at a time and see if my phone's behavior changes...

    Sorry, Dave, I haven't been taking screenshots... but here are my results:

    when idle, my phone wastes about 2-2.6% of battery per hour. I find that to be quite reasonable.

    Of those apps that I suspected because they "prevented my phone from sleeping" I've re-installed the following and have had no problem:
