battery - General Topics

Did you notice that from a little while a lot of programs run un the background without you notice unless use a programa like battery doctor?. Why!. It seems that somebody want us yo run out of battery and charge again so as to spend electricity. Even if you use battry doctor once, they start again soon. Android operating system should take care.This is anoying and you have to charge battery twice or more depending the time your smartphone is on and not the use you make of them

Android is not like Windows. It's normal to have apps run in the background. Actually they don't "run", they just stay there to optimize memory usage in case you call them. Using memory kill apps actually makes your life batter WORSE, cause android will reload those apps anyway a moment later.
It's not a bug - it's a feature. Live with it

It would eat up ram of you didn't, also I would recommend rooting and freezing apps when not using them ie Facebook, Instagram, ect

I don't believe that's correct about shutting off apps

Why are task killers so bad?

I'm just curious. There are 4 apps I want to kill upon bootup.
ATT Family Map
ATT navigator
ATT hotspots
Asphalt
I don't use them and dont want them loading.
So what would be wrong with using something like Advanced Task Killer to do that?
Also on a side note. The captivate comes with a really nice task manager which I thought made it really easy to just shut down a program you aren't using at the moment.
Is there an easy way to install that on the inspire without rooting? Or is there something just like that in the market?

shutting down an app generally causes it to simply reopen itself. theres a link about taskillers in the thread i linked. a good read.
From my understanding it was mainly caused from killing system processes that kept coming back.
I doubt the ATT programs would restart once closed cause are not being used. They just start when the phone boots.
As far as asphalt. Why a racing game would auto start upon boot is beyond me.

You will have to root in order to keep Apps from restarting. Use titanium backup to freeze them.

apps running in the back ground don't use your battery. Apps that go crazy and randomly use 50%-60% of your CPU kill you battery. If you must have a some sort of task killer download Watchdog lite off of app market. It will tell you which apps are overusing your CPU and give you the option to kill them. Keep in mind that android naturally kills a background process when it needs the space.

Thanks for the info.

Can you have to many system apps? Odd.. .

All my system tools, network tools, repair tools, is it possible there tools over lap. Like if three apps all have same program all have start up app killers do they all work. Which wins out.. that's one thing I'm talking battery savers. Network defence. I have apps for there best options but some do things I don't want so can that cause conflict? Like slow phone down. I notice memory being eaten up and wonder if that could be the issue. I mean I want them all but if there duplicate abilities is hurting not helping I will uninstall them. Also how come programs that don't need to start up and come back even after I Kill them. Thanks

Is there any other way to release more system memory each ram beside deleting apps. I hate using over 350ram which I often do
Sent from my SAMSUNG-SGH-I727 using xda premium
Deleting apparently will not free up ram it will free up rom. Your ram is used when apps are running. I have only seen system monitors needed when you overclock and battery savers usually don't help that much. And yes they will overlap and conflict with each other. My battery lasts longer without battery savers and app killers. App killers can also (by default) turn off apparently your phone needs to run and cause stability issues unless you tell them not to (not all will do this but some.) I personally use the back arrow to go back to the home screen and that pretty much stops the app and I get on average about 18 hours out of mt photon (most I have gotten is 1 day 13 hours but I didn't use it a lot at all) and I got about 15 hour average on my evo.

OK I just hate getting rid apps I paid for and are good. Like Rom manager. Super manager. Rom tool box and titanium back up. I mean others too where one does all functions. So if I uninstall a app it wont run, so more memory. Is there a way to clean duplicate system files running or does it need them. Like system tasks not apps. Thanks. Also why do some apps run even when I turn them off starting up is there as app for that. Freeze? Function keep it from running in the background
Sent from my SAMSUNG-SGH-I727 using xda premium
why are you trying to use any type of task killer? its not needed.
why do you think you need to uninstall your useful tools?
do you understand how Android works?
why do you think you need to free up RAM? Free RAM is WASTED RAM....there are thousands of articles on this subject, i would suggest you do some reading on how the system works, before you randomly start killing processes and apps.

Home vs back button exiting apps

From my layman understanding of how android OS works, leaving an app via the home button will place the app in a "pause" state but not remove it from memory until the OS decides it has been paused a while and wants the resources for something else.
Using the back button is supposed to tell the OS that you're done with the app and take the service out of memory usage *IF* the app was coded well enough to cooperate.
But I've noticed on my phone that no matter which method I've used, when I open the stock task manager the apps remain as running services regardless. So does it make any difference on my battery life and system resources which method I use?
Sent from my MB860 using XDA App
well i would suggest that you should close only apps like games or facebook(because facebook keeps syncing and games use a lot of cpu).Other processes for example keyboard do not affect battery life and should be running in the background

Why You Shouldn’t Use a Task Killer On Android

So i saw many posts on which people have asked as to which task killer should be used !
and then i stumble upon this site which provided me the details,
i just complied info
sources-by Chris Hoffman
http://www.howtogeek.com/127388/htg-explains-why-you-shouldnt-use-a-task-killer-on-android/
Android Doesn’t Manage Processes Like Windows
Most Android users are familiar with Windows. On Windows, many programs running at one time – whether they’re windows on your desktop or applications in your system tray – can decrease your computer’s performance. Closing applications when you’re not using them can help speed up your Windows computer.
However, Android isn’t Windows and doesn’t manage processes like Windows does. Unlike on Windows, where there’s an obvious way to close applications, there’s no obvious way to “close” an Android application. This is by design and isn’t a problem. When you leave an Android app, going back to your home screen or switching to another app, the app stays “running” in the background. In most cases, the app will be paused in the background, taking up no CPU or network resources. Some apps will continue using CPU and network resources in the background, of course – for example, music players, file-downloading programs, or apps that sync in the background.
When you go back to an app you were recently using, Android “unpauses” that app and you resume where you left off. This is fast because the app is still stored in your RAM and ready to be used again.
Why Task Killers Are Bad
Proponents of task killers notice that Android is using a lot of RAM – in fact, Android stores a lot of apps in its memory, filling up the RAM! However, that isn’t a bad thing. Apps stored in your RAM can be quickly switched to without Android having to load them from its slower storage.
In summary, you shouldn’t use a task killer – if you have a misbehaving app wasting resources in the background, you should identify it and uninstall it. But don’t just remove apps from your phone or tablet’s RAM – that doesn’t help speed anything up.
Empty RAM is useless. Full RAM is RAM that is being put to good use for caching apps. If Android needs more memory, it will force-quit an app that you haven’t used in a while – this all happens automatically, without installing any task killers.
Task killers think they know better than Android. They run in the background, automatically quitting apps and removing them from Android’s memory. They may also allow you to force-quit apps on your own, but you shouldn’t have to do this.
Task killers aren’t just useless – they can reduce performance. If a task killer removes an app from your RAM and you open that app again, the app will be slower to load as Android is forced to load it from your device’s storage. This will also use more battery power than if you just left the app in your RAM in the first place. Some apps will automatically restart after the task killer quits them, using more CPU and battery resources.
Whether RAM is empty or full, it takes the same amount of battery power – decreasing the amount of apps stored in RAM won’t improve your battery power or offer more CPU cycles.
hope u understood!
words of wisdom by fellow-mates
go into settings - apps and see how many running apps you have. now go to cached apps and see there, how many apps there are. you see? nearly 50% of those apps discovered by you in the processes are apps that you didn't opened ever but they are still opened and running. why? because that's how linux manages its resources. instead of having free ram for no use (what's the point of having 14gb of ram when you only use 1gb), linux fills all the ram blocks with useful apps or apps that you are running frequently so that when you call that app, it will bring it on the screen almost instantly. this my friend, is called multitasking.
and no, you are wrong. if you use a task killer killing the apps every 10 minutes, the cycles the whole system does - opening again apps and caching them, task killer closing them - results in much more functions done by CPU => more battery spent. even if you say that the battery life its the same, you are wrong. when using a task killer IT MIGHT drain your battery with 0.1% per hour. it's not that much, but IT EXIST.
oh and yeah, one thing: android has its own task killer. that's why you don't need one app to kill your other apps. because android its doing it by itself. if you don't believe me, strip down one kernel, open the init.rc file and find the values for task killer.
I've never used those programs, I like to use what the phones have by default
But is good to know anyways
I agree with that...to an extent
Auto killing apps is plain stupid, but I do believe in killing certain apps. In a perfect world heavy apps would just be uninstalled, but plenty of useful apps without good replacements are fairly heavy, and it helps to kill them. E.g. after exiting a game I will kill it because its hogging up valuable ram by running in the background, while still using he same resources it uses at the forefront.
I understand that android, and Linux should manage ram well, but more often then not some app is just out there slowing my phone down. Even an hour later of not using that app, it'll still be in the background using up a lot of CPU and ram I don't have (more importantly battery). Android is great at managing smaller apps, but in my experience, it sucks at doing the same for larger apps.

I don't use automatic task killers, those that are constantly running, but i do kill unused tasks and apps with no reason to be still running. Google services is a common example. It will launch at boot and keep running peemanently, even if you never launch a google app, google services is running, why?
A lot of apps, mostly the free ones, get revenue by reporting anonymous usage statistics (not so anonymous in some cases). So they stick a running service even if the app is never launched again (sometimes even if it isn't launched in the first place).
To sum up, killing everything is bad, but leaving everything to run free can also decrease performance. This can be observed on an android device that has been running for a long time, versus an android device that's just been reset.
some unused tasks will repeatedly rerun even if killed.
This will further decrease battery life and affect performance as resources are needed to keep restarting it.
The best way is to ignore if it takes a small portion of resources or to uninstall the app. Rooted users may disable the triggers via certain apps.

In phones with very low RAM, this becomes a necessity.
Switching programs take up a lot of time to process unless there is a sizable free RAM

let me tell you something about google services...
when you installed your rom, you had to check two options from google services - location and another one.
if you are on stock, those options are available in settings also.
the google services are needed (you are running a google os, right?) because without it, the location feature will not work, the play store will give you headaches and not to mention, google now that needs that service like water.
if you kill that process over and over again you will not gain anything because that service will keep restarting it until you will give up. ah, you will loose a massive amount of battery if you do so
another thing, the google service is a system app. system apps have priority in resources so even if you kill now, as i said, it will restart after a few seconds because some apps that you are running are requesting that service.
as someone said here, yes, even I kill games after I stop playing, BUT, I do it from the task manager built in. Settings - Apps - Running apps etc.

No that is wrong.....it consumes more ram it self

Normally to kill a process I use the Running Tab in Apps, If any recently opened app which I feel should be closed is open I kill it!Though I leave the google services untouched!
Stopped using Task managers and Battery saving apps long time ago!
Want to really save the juice? Try Under Clocking! and killing the bloatware(saves RAM too!)
I used to have a task killer but the more I killed apps, the slower my phone was, so I eventually ended uninstalling it.
great post. lots of usefull info!!
Instead of using a task killer to keep on eating your battery life, simply either delete the app or disable it in your system if it's a system out (eg: default browser, bloatware, etc).

Assuming you are replying to me, your response is a bit ambiguous...

Help about greenify setup! And a question about battery monitor.

When you-they say that task killers are bad, you also mean the stock task killer every phone have? I am talking about the one you enable it by long pressing the back ( or other ) key and then just press clean to delete all running apps.
Every app we open it must be killed/hibernated in order not to consume ram and battery. So we must put ALL the programs in greenify hibernation mode? :S
I am a little confused.
I have an Oppo Find 7a.. Should i use greenify or system battery/app management? And how?
Also i've installed Gsam Battery Monitor, but it doesnt seem to work well.. Sometimes timer reset, other time the app closes itself..
Also i noticed that youtube app doesn't display on greenify apps. Why?
Yes when people say that appkillers should not be used they mean also the android default app killing software. And they are right when they are saying that. Installing extra app killing software to your phone just consumes memory and battery life
And what about greenify?
I noticed that when i open the cm browser, also facebook opens! There is a wake-up path called << AttributionIdProvider>> which i cut it off..
Also there is another wake-up path for facebook something like this << lollipop update service >>.. What is it??
Should i cut it off also?

I have not used Greenify so I cannot say anything about the features. To be honest, looking at the apps description I cannot see that it does anything special but prevent the apps from behaving the way they are designed to. Some individual apps may be poorly designed or implemented and may consume more battery life than necessary. In most of the cases doing this kind of hibernating will not help at all.
Most users say that greenify works very well.. I am surprised that you never heard of this program.
And what about battery monitor program? Should i have it ran all time?

The purpose of battery monitor apps is to give you detailed information about battery consumption. You for example identify if some individual app is consuming too much battery for some reason. If you do not do anything with this information, there is no reason to keep the monitor app running.
The default closing of apps in the app drawer does not kill the app properly. Greenify completely stops the app via the app info or with root. All apps have to be hibernated in order to not consume battery but you should not hibernate apps that you want to have running in the background like whatsapp, hangouts, vpn, apps whose widgets you use etc. Youtube can not be hibernated because it is a preinstalled system app and these can only be hibernated if you pay for the Greenify donation package(which you absolutely should). For the Battery info app it depends on how it measures your battery usage. Try to hibernate it if it doest measure your battery stats remove it from the list again.

Not necessarily. But it's a good indicator. The most battery is consumed by internet traffic and the CPU/GPU when the display isn't on.
