Hi there
sorry for asking I am somewhat new to Android.
I read very often that Google Maps should be froozen because it is a battery sucker. Now I am wondering how an application could drain the battery when I actually do not run the application.
How does Android itself deal with applications and quitting them?
I read conflicting recommendations about task managers stating that Android itself deals with this better.
So what is this freezing of apps? Does it prevent Android from starting it automatically?
Thanks for any education

Android is based on multi tasking ..ie many apps can run in the background even though you are not using it at the moment..say if you are using maps and once you're done you just exit it. However maps app will be running in background if not exited in proper manner( either using the app or by going to running services in settings and force closing).
Also certain apps are configured to autorun under certain circumstances ..say for maps or Facebook app! -try keeping your wifi /data off! Go to settings/apps/running services/menu-cached process and force close Facebook,maps however once you turn on data /wifi they will run automatically! Just check it out yourself ..
Solutions for such problems could be either to use autorun managers or to freeze the app -freezing makes the app unavailable for use until you de-freeze!ie it blocks the app from running ..
Above said statements /examples are from my experiences!correct me if I'm wrong!

Yes but be careful, if you use task killers to kill them, they may start again and this will consume more battery than the program running.
Imho the best way to go about this is the following:
- go get Quick System Info PRO from Market (it's free)
- set it up so that it places a CPU usage icon on your status bar (the notification for that icon is also animated)
- when you find the device is sluggish and CPU usage is high, tap the notification and go to the Processes tab
- sort by CPU usage
- kill whatever it is that is using the CPU
And you may also kill all tasks just once before going to bed or something, just in case.
To stop maps, use autostarts disable all maps have in there, then you can be cool

When I open some Apps, 10 other Apps open along with it. Is rooting the phone the only way to have access to the means to stop this?

Don't pay so much attention. In general, those applications don't use your cpu and battery. Android has its own task manager system.
Yeah dis is even happening to me,the reason is so simple like one app needs the other apps so they are even opening up.

what the appl you using which is opening others appl can u name the apps
if you kill apps, they will probably get restarted automatically and left in the background. If the apps are working correctly, this is not a problem, as a well coded app does not use CPU/battery when in the background.
Actually, I just quit using a task manager to kill tasks (I just let Android kill them as necessary) and I have no problems (phone is not slower, power drain is not higher).
Maybe the thing is that after you stop a task in a task manager it does not update immediately and you don't see the task being restarted, and when you go into the task manager after running some app just then you see the apps restarted.
Also, some apps are very generic (maps) and used by other apps, and some apps need to be running all the time (latitude, mail client, widgets, etc.) and killing them would make them not work properly (widgets no longer updating, not getting new emails, etc.).
My advice is to leave the apps running if you are not very sure of what you are doing, because the OS will eventually kill unnecessary apps, and until then they should not use any CPU or battery.
Only thing is to stay away from badly written apps, the ones that use too much CPU even when in the background or when phone is sleeping. You should probably wait for a night after installing a new app to see if you have higher drain. If so, just uninstall and search for an alternative.

Seems like many applications spring back up after "killing" them though the Android task manager or any of the task managers available in market. Is annoying the hell out of me. If im not using the app I dont want it to.run in the background..
I understand that messaging applications need to run in background but not all.
How do you guys make sure
that any application which you close "remains" closed until the next time you open it?
Thank me if I helped you..

You might try Gemini app manager to disable auto start apps

Easy Task Killer can help too..
use Easy Battery Saver too along with it!
Thanks.for your replies guys. However.i believe the main question here is,.how.to.stop these background app processes from running until the next time I start them manually.
Problem with task managers is that they stop these apps after a certain interval. Once they do, the.apps restart after 2-5 seconds. And.remain there till the next interval of the task killer is reached. This in turn take up more memory a compared to keep the running.. In addition, these apps run in the background on their own taking up a junk of memory/processor space..
Thanks again for your replies. Please correct me.if my understanding is wrong and you are feel otherwise.
Thank me if I helped you..

Those "apps" that you say keep opening are actually the processes running in the background. I know of many apps that keep re-enabling their processes after killing them. (IE: Facebook, some Google stuff, and a couple games that run in real-time)
Best solution: try to go into the app's settings and see if there is an option to disable anything that would require a background service to run, IE: sync, updates... If not, then just stop killing that app. Ignore it in the list or set a task killer to ignore it. If the app keeps re-opening, you killing it all the time is only doing bad because it puts more stress on the operating system because it has to take the time to reinitialize the app/service. If you are really that anal about background running apps, set android to limit a lower amount of background apps to run.
Like asdot suggested above use Gemini App Manager to disable the apps autostart permissions. If an app is set to automatically start after a certain intent is broadcast by the system (ie, at boot, or at a change in connectivity, etc.) you can use Gemini to stop that app from automatically starting. You can stop an app from automatically running in the first place instead if trying to kill it after it has started.
I've tried doing a lot of personal research before asking. I have watchdog and betterbatterystats. I found 2 apps chewing away at my battery. After using the app I always press back and then it pops up do you really want to exit and I select yes. However, I look at the processes and I will see it running in the background. Using stuff like advanced task killer (and a bunch of other killer apps) doesn't help, as soon as it kills it, the thing just spawns again. I had to force close it or sometimes reboot the phone. Is there any app that locks down these apps so it only allows process to run when the app is in the foreground and as soon as we leave it closes all aspect of that app? (I can't uninstall those 2 apps cause they are kinda essential; but by no means does it require any background process or need to be constantly running). So far it only runs in the background if I opened the app once, but if it starts to auto run I'm screwed.
Is there any app like the cydia backgrounder where I can set a whitelist or a blacklist that only lets the app run in the foreground and as soon as I press home it will stop all its process.
Autostarts in the market. It let's you see what apps start up under what conditions. I would assume you can just doable all conditions the apps can start up from and it would do as you describe.

I have autostart doesn't work, ok I give you an example:
Groupon app. If you don't load it after a reboot it doesn't run, however as soon as you opened the app once. Theres like no way to close it.
Come-on... one of you guys must know how to close an app and prevent it from loading up after I leave the app. Isn't there anything like cydia backgrounder that I can set so apps are only allowed to load in the foreground and closes as soon as go back to the launcher???
Solution
The best solution to this is to install titanium backup. After that, create a widget in ur homescreen and select titanium backup widget (action). Then, select the action freeze/defrost/launch and after select the app ex. Facebook and create the widget. After, you will notice that the widget for the Facebook app has created to ur homescreen with a green locker. If u press on it, it will lock the app (freezed it actually) so it doesnt run. if you want to run the app, tap again on it and automatically will defrost it and launch it.
Hit thanks if i helped you

I just want to add some info for a better understanding even if I understand what you meant.
1. A package showing in the process list after you chose "exit" is a sign for a service running. This is not necessary bad as there are many services doing nothing but waiting for events to process (of course some service do stuff in the background and it is good to look after those).
2. In Android there is no such concept as an app, there are activities (dialogs), and services and both have pretty complex life cycles (not just opened or closed) as you can see here
But back to your question: the right way to get rid of apps you don't want/need (also called bloatware in some cases) is to freeze them. One good tool for doing that is titanium backup.

I understand the point of apps that show up and are 0% cpu usage like facebook etc. I was only using it as an example. There are plenty of other apps that do infact chew up cpu and battery after it is loaded for the first time and is unable to close the background processes (they are shown in the watchdog and betterbatterystats). So the only way is to freeze and unfreeze everytime I use these apps?
I have been experiencing a problem with background apps sucking up all my phone's memory on my EVO 4G LTE. When I use high resource apps like high graphics games, other apps like Facebook, Google Maps, Google Plus, etc. start to cash and slow everything down. Sometimes it gets so bad that the phone will completely freeze and I have to do a forced shut down via volume down + power. If I use task manager to kill all the processes before using one of the high resource apps, it works better for a while, but then the processes I closed stay themselves back up again the movement I exit the app I'm using. Then I have to kill them again. Sometimes they restart themselves as fast as I can kill them. Is there some way to prevent these things from opening themselves so they are only using resources when I actually open them myself? My device is routed and I'm running MeanROM.
uae greenify, it hibernated app when not in use
the greenified app will active again when you open it, after it you can hibernate it again
Settings - Developer Options - Advanced - checkmark on don't keep activities...

Also, ROM control by jrummy has a really nice feature for disabling autostarts from all of their specific callers.

Hi there ! Today my simple question is how to increase battery life of android mobile ! Please tell me some tips cause I'm tired ?
use a taskkiller to Close unused apps!

Never use a task killer

- Turn off all unnecessary connections. That includes GPS, NFC, Locationservices, Sync, etc. That alone will save you days.
- Turn off WiFi when you're not using it.
- Greenify all apps before you turn the screen off. Android keeps apps running in the background for quick access, but it eats battery. Yes, greenifying them will mean they take a second longer to open, but it'll save battery life.
- Turn down the brightness. Use LUX to go below 0%. (Which doesn't actually mean the screen turns off.)
- Disable or delete all bloatware, or as much as you can.
- Using a MicroSD? Drop a .nomedia file in every folder that doesn't need to show up in a mediaplayer. (pdf's, comics, etc). You can still open the files through a filemanager, but MediaScanner/Indexingservice won't freeze on them.
- Turn off all unnecessary sensors. Especially if you're using a Samsung, those have quite a lot of sensors.
Is there a way to get NOTHING running in the background?
Maybe you should remove bloatwares using titanium backup im doing this on my galaxy note before. Even on my s2

Developers options > Limit Background Processes > "No Background Processes".
Remember that this means that if you're writing an email, and you open the browser, the email is gone. If you're listening to music, that's it, you can't do anything else or the music app shuts down.
There is absolutely no need to use task killers or anything like that on an Android. Android is designed to run with apps cached for quick opening of them. And designed to run on little free memory.
As long as apps "behave", it will not affect your battery having them running in background. If the odd app does seem to cause trouble, try using Greenify to hibernate such apps.
Having no apps running will definitely cause more drain for you, as it takes more cpu power to initialize them every time you open them, or the system does. Hence why task killers do more harm than good. :good:
If you have battery issues, it's likely poor reception on data, an inefficient setup or app wakelocks. Use GSAM to see about that.
