    Does anyone notice that 'Android System' battery usage is very high?

    I ran a test where i displayed just a photo

    Battery Indicator
    3G Watchdog
    Photos
    Advanced Task Killer Free

    within 20 minutes the results on the battery are the following:

    Android System: 63%
    Display: 24%
    Cell standby 13%


    Any thoughts on to what might be causing Android System to be so high, only them programs are running. Does this happen to your system?
    I notice with web browsing its about the same usage as well, with wifi and internet taking up small amounts.

    Cheers

    Gary.

    Just means its using relatively more than the other features, and not that it's using abnormally more power.

    Remember that the % all have to add up to 100%. Also it's the same situation on my desire and I'm guessing everyones desire. Just goes to show the display's energy efficiency

    So it doesn't mean 100% of the power that it could pull from the battery, but just how all of the power it is currently pulling (which ideally will be a whole lot less than full drain) is being used? I.e. 100% of the current usage (current current? :) ).

    How do you get these measurements? I remember reading about this being in 1.6+ but I don't see anything on my new Desire.

    Ohh, there's lots more under About than there was in 1.5. Silly me.

    If you look under android system, what is being run? Have you checked against the Spare parts app?

    Cell standby should be low, otherwise it indicates low signal and the phone hunting for the network to reconnect ;)

    Mine is 94%, and I think it the battery is drained in about 1 day without excessive web and other app usage.
    I noticed this after I played with installing some useful apps, and configuring my screens with icons and widgets.

    However, I don't have that many programs installed, just about 10 new apps I have installed, and just 1 widget that auto-update. I even replaced the big clock from HTC to a smaller one on the home screen.

    Do you know what might cause this? Is this normal in my case?

    I also installed a task killer, after seeing this high usage, but I've heard that's not recommended for Android 2.1 & 2.2.

    I have a HTC Desire with Android 2.2

    from my previous post:
    http://androidforums.com/htc-desire/155051-desire-phone-not-sleeping-issue.html#post1421147

    there are several ways to do it if you want to check what apps are running constantly.
    1. buy systemPanel app from the market, very informative app and from settings put it in monitoring mode from where you can get information on what services, when, or what apps and how much of processor power it uses.
    2. use ADB with adb logcat command (however it would take some time for me to explain how its done, but look on androidforums or xda-developers website for ADB usage)
    3. from main screen on your phone press menu button, go to settings, about phone, and then battery
    4. famous service command *#*#4636#*#* or get spareParts app from the market which works as the service number and then go through battery history, other usage or through partial wake usage or through any other option in that menu
    so all these should easily identify badly coded apps that are constantly running and after dealing with them your phone should sleep like a baby
    good luck :)

    System Panel pro is a real good way to monitor your phone's activity throughout the day and analyze what's going on. Even with no phone service, my call standby is at 46%.

    I can't find any abnormal app that might use the battery and cpu. However, battery usage has still - 94% the Android System and rest of them just 2%.
    Nevertheless, the battery isn't that bad, it lasts about 24-30 hours with normal usage (ab. 20 min of net, 3-4 min talk time, 10 min playing, etc..., rest idle)

    SystemPanel (even the lite version) is quite impressive and looks nice.

    The past few days android system was below 50% and battery hasn't been a problem but today it's 93% and after about 3 hours the battery is down to 63% from 100%. I can't seem to pinpoint what part of it is eating the battery, I got most of the services turned off.

    Help! Simple minded phone user. I have the same problem, My battery drains from one search on the internet. I cannot use the GPS, my battery would not last 10 min. Is this normal?
    I don`t have open apps, I`m not that phone savvy. I only use email,text and occasionally Google. My kids have I-phones they can play games,watch movies,GPS and phone is still charged. Forget logging on FB mine will drain the battery.
    Is my phone a lemon? I really miss my simple blackberry.

    No, that's far from normal.
    I don't usually advice Task killers, but try get one, just to see what's running.
    It could easily be an app that is badly coded and causing the phone to drain.
    Now that I think of it stuff the task killer and get Spare Parts and look under Partial Wake Usage.
    Let me know what it is.
