way to kill all apps running

[utengineer04]

Hello, is there a way to tell if you have apps running in the background, and is there a way to stop them. I recently installed PowerAmp (best thing ever), and got to work this morning and noticed that Poweramp was playing, and my battery was dwindled down. Is there a way to check and make sure that when I put my SGP down for the night that there aren't any apps running in the background, thanks.

Turn off the Player. If you are sleeping why do you need it on?

Ok seriously,

I have the same problem. I have turned off the GPS, the wifi, turn down my sync settings to once a day blah blah blah.

I have other android devices and do not have this problem with battery life.

Eliminate Free apps that send you info back to their servers

Lastly find a app killer widget and check it before you turn off the screen to make that there are not any apps running in the background that take up CPU.

I use Android Assistant for app-killing. In all honesty, though, you really should just make sure power amp is paused when you back out. If it isn't playing anything, it doesn't use any battery in the background.

I used to use Task Killer, but I found that the stock Task Manager did fine. If you really want to kill off everything, use the Task Manager and instead of viewing Open Apps, view RAM. Then clear memory. Sometime that kills things that do not show up on Open Apps.

It is my understanding from the Android forums that apps don't "run in the background". They reside in in RAM until you open them. That process returns you to where the app was when you left it.

Yes, basically, Android will do a much better job of task managing than you ever will and in some cases you will use more battery if you kill it if it is an app or process that the system needs at some point, which means the system will restart it using more CPU cycles. If you use a utility like System Panel that allows you to view the stats on active applications,you'll see that most of the time most of them are using between 0 to a fraction of 1% of cpu cycles. If the system needs the, pulling them up, doing what needs doing and backgrounding them again uses very little battery.

You are not going to do a better job than the system does already.

It is odd that you can close everything, go to stock Task Manager, exist everything in Active Applications...then go to RAM, clear memory, and you can get a message similar to "9 applications closed"

What the heck is open and running that doesn't show up on "Active Applications?

I really don't like, in Android, that so many apps do not have a simple "Close" or "Exit" button. You have to back out many times to "close". With some apps, there are so many windows to back out of that I just abandon the app, go to home screen, Task Manager, and kill it that way. Seems like a major oversight. I have two or three apps that have a distinct "Close" "Quit" or "Shut Down" button.

android actually has an internal app killer/ closer, but if you are rooted you can run a script called supercharger v6 seen here on xda http://forum.xda-developers.com/show....php?t=991276/

scroll down a bit and read the first post and it should help you.

Just a side note i have never installed this on any native android device my main phone is a htc touch pro 2 that is dual-booted with win. mobile and droid and without this script my phone would be terribly slow i you have any questions ask on xda or pm me i might be able to help

this script btw runs parallel to the internal app killer thus speeding up your phone.

Blackdog, clearing the RAM doesn't have an effect on the battery life. As loutingle said, it gets its last state written to the RAM and then can be resumed. When you clear the RAM, what you are doing is emptying this cache. Android already clears this when it is low on RAM. I still clear it when I'm putting it away, even though I know it isn't really doing anything.

Well my task manager doesnt show anything running anymore because of some glitch.I always went there to shut off apps.Now i just ignore it all and use my player and when Im done for the day I shut it down which Im sure closes everything.

It's frustrating that you can't just close an app neatly but unless it is designed to continue running in the background (downloading data or recording GPS tracks, for example) then there is no need to exit like you would in Windows. It won't drain the battery or clock up the CPU cycles or RAM (as has been stated already, Android will clear the RAM if it needs to)

Exiting fully and clearing the RAM will actually strain your resources more because they will have to open the app from scratch next time you want to use it. Therefore, pressing the Home button is often the best way to exit an app, especially if it is one you use frequently.
