    Question Processes starting on their own

    When using either a third party process killer, or the default one, it seems as though a lot of processes automatically repopulate themselves soon after being killed by a task manager of some sorts. Is there anyway to prevent this from happening? I swear I've searched all over the phone, I've pressed the "settings" button and virtually every app screen I can think of. There must be SOMETHING I'm missing. I feel like these processes add to the already rapidly draining battery issues I see on a daily basis.

    -Thanks

    a general rule of thumb is to not use a task killer at all. Since andriod handles its own memory fairly efficiently. The apps that continually pop up after killing them are system apps. One way or another, they are tied to common things in the operating system. The only true way to stop them from coming up would be to root your phone and either freeze or uninstall those apps.

    As for saving a little battery, you can try turning down screen brightness. Toggle your mobile data on only when needed or try a app like juice defender which will automate that process. Also limit the amount of Widgets on your home screen and also limit or stop all apps that require constant syncing such as Facebook or twitter.I hope that helps a little.

    Edit- just a little info on the apps that do pop back up. When they are sitting there idle they don't use any cpu, they are just sitting there cached for easy access for the OS. When you kill them they abruptly stop and the OS has to reopen all of them again. That does use your CPU. So in the long run killing those apps over and over is actually kilibg your battery faster than if you just left them there.

    Thanks for the rapid and informative response. I suppose I'll slow down on the task killers, and go back through to make sure "synced" apps are not doing that.

    I LOVE this phone! But damn, it doesn't mess around with the battery life. It loves to run away!

    Some of this is redundant since I already said it but, this is some Info I had saved in my note pad(don't remember where I found it.)after you have ran through any changes it should help the battery.

    Use Android’s Built-in Battery Usage Screen

    There’s a screen built into Android that most casual users probably don’t even know about, and it can tell you exactly what is killing your battery. Head into Settings –> About Phone –> Battery use to see what has been killing your battery life.

    From this screen, you can usually see what apps are the worst offenders, and you will probably notice that the biggest problem—at least, the biggest one that we can fix—is actually the backlight on the phone.

    Adjust the Backlight to be Less Bright

    Since we’ve already determined that the backlight is usually the biggest problem, you should probably adjust the settings. Head into Settings –> Display –> Brightness, where you can choose to automatically adjust, which usually works fairly well, or you can just turn the brightness down to the lowest acceptable level.

    You should make sure that the screen timeout value is set to turn off quickly as well.

    Disable Your Wi-Fi When You Don’t Need It

    Wi-Fi can really speed up accessing data on your phone, but it can also be a big drain on the battery if you don’t need it enabled, especially when you are out and about… The phone will try and scan for a wireless network even though you may not want it to.

    You can easily toggle the Wi-Fi on or off with a widget or shortcut—there’s a built-in widget included in Android phones, or you can use the AnyCut or BetterCut utilities to create your own shortcuts to directly turn them on or off without requiring a widget.
    Disable Bluetooth if You Don’t Use It

    If you aren’t using a wireless headset, there’s no reason to have Bluetooth running all the time, and you should probably cut it off to save the battery life. If you never use it at all, head into Settings –> Wireless & networks–> Bluetooth.

    You can also enable or disable the Bluetooth when you do need it, using the power widget.
    Use the Power Widget to Easily Toggle GPS, Bluetooth, Wireless, and Screen Brightness

    Android includes a built-in Power Widget that can easily toggle these settings on or off—just long press on the background of one of your screens, choose Widget –> Power Control to add it to the screen.

    This is probably the simplest and easiest thing that you can do to save your battery without having to dig into the settings all the time.
    Disable Apps that Sync Constantly

    The built-in Email application (not the Gmail one, which uses Push technology) can suck the battery badly, because it syncs on a too-regular basis, especially when you have lots of accounts—each one of them is set to sync every 15 minutes. You’d be better off setting it up to sync manually, but if you want it to sync automatically, you should set it to sync less frequently.

    Open up the Email application, head to your account, and choose Account settings –> Email check frequency from the menu. Change this to something more like an hour… or never. You can always hit refresh manually when you want to read your email.



    The same thing holds true for other accounts, like Twitter clients, which are even less important to update all the time. For Seesmic, you can head into Settings –> Background Updates from the main screen. For the official Twitter app, the settings are similar.



    The Facebook application polls automatically in the background, and you can customize the refresh interval for that as well—if you don’t need Facebook updating all the time, you should set this value as high as possible.

    From the main Facebook screen—the one with the icons—head into Settings –> Refresh interval from the menu.


    Disable the GPS Location Features

    One of the biggest battery sucking features on my droid is the GPS… When I have navigation going, the battery dies far too fast, so I end up having to keep it plugged in the whole time I am driving. This makes sense… but what you might not know is that a lot of other applications use the GPS as well.

    You can also change the GPS to use wireless networks, and uncheck the option for Use GPS satellites—this will make the GPS a little less accurate, but it will save your battery. Note that you probably want the real GPS enabled if you’re using Google Maps Navigation.



    Additionally, you should turn off the geolocation features in your Twitter client, weather application, or whatever other apps that you really don’t need them in. If you want to keep it enabled, that’s great, just realize that it does drain the battery, so uncheck this option to help

    It should go without saying, but we’ll say it anyway—you should remove the apps that you don’t need anymore, especially the ones that are draining your battery as determined from the android battery panel or task manager. Head into Settings –> Applications –> Manage Applications and then you can click the Uninstall button for an app.


    Disable Home Screen Widgets You Don’t Need

    If you’ve got loads of widgets that are pulling data from the web, that means they are likely pulling down data in the background all the time. You should try not to go overboard with these, or remove the ones you don’t actually need.
    Disable Animated Wallpaper

    Yeah, that sweet animated wallpaper doesn’t help your battery any. Get rid of it for a small extra battery savings.

    Keep the Battery from Getting Too Hot

    One of the quickest ways to kill a battery is to leave it out in the sun—try and keep your phone somewhere that isn’t too hot whenever possible. You’ll end up needing to replace the battery a lot quicker if you don’t

    Running apps on your phone can be terminated with the built in feature of the phone by holding the Home key and selecting Task Manager. As mentioned before just because you see an app is listed under processes doesn't mean it is necessarily running.

    Ronnie I think that may have come from what I'm going to link below. In short, many Android apps depend on one another and the OS as a whole is very good at natively managing RAM. I think the videos in this thread explain how Android actually works in that regard. Good info.
