When I got my desire it was stable and fast the more I put on it the slower it gets . I've tried numerous task killers and some of them screw the phone up . On one thread someone suggested leaving the phone to manage its own background programs . What does everyone thing is it better with no task manager ?

My personal choice is to leave taskiller off the desire. I put a taskiller on and almost immedietly the phone started acting wierd eventually getting into some sort of loop rebooting itself. After many reboots it eventually gave me enough time to uninstall the taskiller. Obviously that was the problem as it has never repeated itself since. My phone runs fine without it.
I really cannot understand why people use task killers. As I have said before if you are a real expert and you have a badly behaved program that you have to use you might just have to use of a task killer.
If you are not a real expert or are even asking the question don't use one. You will almost certainly end up with worse performance and decreased battery life.
I have 60 plus applications on my Desire and don't suffer any slowdowns or other problems. There is just no need for task killers/managers. This is NOT windows!
Android has a built in task killer. It's pretty good and IMHO difficult to improve on.
Kill Task Killers!!
Agree with others, you only need it to kill a rogue app without reset.
I have around 100 apps and the only semi-slowdown I can feel is by putting complex widgets and live wallpapers together. Otherwise I've tried some of these task killers and even killing all the 20-30 processes 'frozen' or active in the background had no effect.
Still I keep it in order to kill those badly designed applications that have some glitches in going back to the main screen or rarely get stuck.
I would think that if you experience some problems they are not related to the quantity of applications open in background, but rather by a single one that has some design flaw.

Well said.
The trouble is people use a task killer when they don't have a problem. They just kill apps. without a clue what they are doing.
I repeat don't use a task killer until you really have too.
and what about battery life?is too many running apps affecting battery?

Doesn't affect battery at all. Almost all apps. are suspended in the background when you move away from them. Task killers are the major cause of poor battery performance as killed apps. then have to be reloaded instead of resumed. Try switching between say six applications, and using them, with and without task killing. I bet you will see a massive performance gain without the task killer.

If an application keeps going in the background in some way/service it's because it's meant to be, like an updating rss feed reader, a live wallpaper, an email client pulling mail from the server, widgets or music player streaming/playing music. If you don't want those to run in the background you obviously should set them not to update, remove them from the desktop, stop them manually, etc.
Otherwise every other application you open and then leave when you switch to another application, gets stopped and 'frozen' in the state it had so that when you switch back to it or reopen it, you find it in the same state, giving you the impression of having been running in the background (but it didn't).
It's a smart way to combine the speed of single-running applications in dumb iphones and the flexibility of more complex os like WinMo. It's also apparently the same way as WP7 will work.
Like mentioned above by killing processes you mostly cause disruption in the pre-ordered way they work and probably cause more battery usage since they have to restart from scratch for the most part. More importantly real-time monitoring of processes and auto-killing them is most likely eating battery a lot since every real time monitoring does that, like many real time battery widgets and such.
Ok.thx for answers guys.i am geting rid of task killer right now.
Same here .. I'm a techie on most things obviously not Android must try harder !
Must admit did complete hard reset yesterday got rid of task killer after first posts phone seems more stable

I have a task killer, but only for killing appliactions which aren't written good and causes some lag or they don't want to close..
I just looked at the comments on the Advanced Task Killer (free, high in the list in the Market).
I wanted to believe you guys here at XDA. But I went trough the comments on that ATK and 95% was 4 to 5 stars. All with reply's like:
"must have app"
"should be included in Android"
"doubled my battery life"
Now if SO many people say that, I can't imagine that they are all wrong. Why would they all lie?
I myself have been using that ATK for a while, killing only some things that don't close (like games,Facebook or Twitter, etc...)... battery life is still not as good as I would like it to be, but I only have had my Desire for a week.
Are you guys REALLY sure that stopping to use ATK will improve battery life?

Read this article:
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
it's the placebo effect. A While ago there was a thread on a winmo forum for a new overclocking application. It had tons of "amazing", "must have", "goes way faster", comments, it became incredibly popular. then the developer made public the fact that it was a social experiment and the application did absolutely nothing other than having a nice interface for reporting fake cpu .
As said if you have a single bad-behaving application (which is very rate) only kill or rather uninstall it. Games don't run in the background, battery becomes great after one-two weeks, but still you can't expect it to run for 10 hours of continuous heavy usage. Buy a second battery if you need that

No one is saying they are lying - personally I see it more as a placebo effect, but I do understand there are certain situations where task killers come into there own. Having owned 3 Android phones though, I can say that in my case leaving Android to do its own thing works very well for me - I don't believe that it actually increases battery life significantly, but I do firmly believe it improves the overall stability of the platform.
One thing that probably should be added, is that using swap on an Android device will cause problems with Androids own internal resource management because it cannot distinguish between real memory and the virtual memory made available using swap. See here for more details. I wouldn't be at all surprised if those people who get the most "benefit" from task killers are also using swap.

I have heard somewhere that installing many apps can drain the battery more quickly
I just want to know wheter or not installing apps that are not running in the background drains the battery?.
Thanks.

Not if they are not running in the background
Some people have installed more than 300 apps (user apps)
scribbled from my note 2 (N7100)
It's no different than your computer. You can have 50000 apps installed, but only the ones running consume active (ram, battery, network) resources.

Be aware though that many do run in the background even if you haven't run them.

In General Yes, but I'd say depends on the apps, if there are 200 quality apps, (however I don't know how many are there in Play Store), and you've not turned on the background data for them, then it might not drain much. But if you've even 5 crap apps installed then they'll be enough Culprit to hog the juice more than those 200 apps.
In short, DO NOT install crap apps, do not install whatever you see. Read user reviews, see ratings, then decide. I, for me, think 3 times before installing one, even if it comes from a Top Developer tag.
Yes it does take more battery. So install the apps which you are going to use.

Can you please back this up? Used storage doesn't increase battery usage.

It totally depends on applications you have installed
If you have hundreds of application and they don't autostarts or have no sync function and just occupying storage, it won't drain battery, in usual course i do have 150 user application installed but hardly it even drains recordable juice except some of it requires auto refreshing and sync

There are application that can disable the apps you've installed from auto starting or running in the background. Usually the biggest culprits are the free ad supported apps that tend to randomly call up even when the phone is in sleep mode. There are many ways to stop it from happening.. If you can pay for ad free app then go for it otherwise a lot of 3rd party apps will allow you to disable those features. I don't understand why someone would install 200-300apps in the first place when you only end up using less than a quarter of those. I guess its that "you never know when you're gonna need it" habits.
Sent from the Rabbit Hole
There are a number of apps which do run in the background, even when you don't manually run them first. Applications can register receivers to trigger at various events (such as boot-up complete, call ended, etc) and complete tasks in the background, or register themselves as services. You can check these with an autostart app, or I use ROM Toolbox (https://play.google.com/store/apps/details?id=com.jrummy.liberty.toolboxpro&hl=en - there is a free version available too).
On top of that, apps can also run scheduled tasks which can wake the phone out of deep sleep in standby, which can cause additional battery drain, through either CPU or network usage.
Unlike iOS which kills most background apps after a couple of minutes, Android apps can run indefinitely in the background, unless of course they are killed by memory management first.
Android experts all say task killers are unnecessary (except to kill a misbehaving app) because the android OS is designed to use all the available memory and it costs as much battery power to maintain a memory containing nothing as memory containing something. So emptying memory by killing an app just causes android to immediately load something else (or the same app) back into memory.
My question therefore has to do with apps like Greenify, which "hibernate" apps till they are actively called. Is hibernation just another name for removing apps from memory and therefore as counter productive as task killers? I can see the subtle differences but they seem minor compared to the similarities.
What do the experts who know android say? I don't know enough to really know.
Any studies to show an advantage (battery, etc.) in using an app like Greenify vs not?
Thank you.
Jeff
For me, I tried all of those battery saver app, none of them actually significant save battery, plus they use up some of your ram. I read somewhere says that android itself can handle battery save plus manage apps in it memory just fine.
Nam Huy Linux http://namhuy.net
Task Killers use extra CPU cycles and can lead to loss of battery life.
I'm not sure about hibernation but I think it just prevents apps from being started automatically when the device is powered on and therefore saves battery and CPU.

I have to agree with task killers not really being necessary, especially with newer devices, for the most part. I've had and used ATK for years now and use it on occasion but by no means do I use it regularly. The only app I use that ever misbehaves is Google Voice, while deleting a bunch of texts it will on occasion hang up and need to be killed. The two scenarios I use it regularly is before playing "some" games and usually before using VLC before watching a video. When using VLC I will often pause, skip, rewind, fast forward and on occasion use slow motion to further investigate any milk shake, if it's looks to be worth my time. In those two scenarios I believe it does make a difference. Other than that I don't use ATK and it's not needed.
As for Greenify, I've been using it since it was first released and I won't hesitate to admit to being a big fan. You don't want to use it for everything. Any widgets that need to update or apps you want to get notifications from I would not hibernate, even though it is supposed to work with some notifications I personally have never tried it. Having said that I have a ton of apps that I do hibernate with Greenify. System and user apps. And if I remember right I believe the auto-hibernate works at some point in time after your screen has shut off. If I'm wrong someone please correct me! I also have to say that using Greenify is part of the reason I routinely see 1-2% battery use during 9-10 hrs of standby and I have Never had a problem with wakelocks. I think it is unrealistic to attribute good battery life to any one specific configuration setting or app, it's going to be a combination of multiple things. And I think Greenify is part of the puzzle along with wifi use, wifi configuration, LTE use, display brightness, sync frequency, location settings and so on. My N7 is not a good example because it gets used very hard almost everyday and I still typically see 5-7+ hrs of screen on time and as high as 9 but rarely. My N5 also typically between 5-7 hrs sot, often as high as 9 and once saw 11 hrs of screen on time. And... I actually have screenshots. I would say give Greenify a try, used properly you will see a benefit. For what it's not worth, just my two cents!
Thank you. I've also used Greenify for a long time but don't know enough to really evaluate its effectiveness. I have not however dared to use it for system apps because of the warnings.
Which system apps have you hibernated without problem?

Google search, chrome, keep, news and weather (don't really use), youtube. Google play books, games, movies, music, Google+ and Hangouts I have disabled because I use other apps but those could very well be hibernated except for Google+ and Hangouts (notifications).
I missed currents, email, korean keyboard, google pinyin, iWinnIME, google play magazines which I have disabled also but any of those could be hibernated.

No problem. I just realized I show google search in my list of apps I hibernate but I should mention that I don't use google now. If you do you probably want to leave google search alone if you want google now notifications.
That's fine. I don't use Google search, google plus, Hangouts, etc. Etc. Either but was afraid to disable them because of potential problems when the next system update comes. How do you disable them? Titanium b/U or something else?
(I'm rooted).
Does enable this option help save battery life? as the process is suspended once user quits it. We all know some roguewares would keep themselves active even though not running forground and draining tons of battery.
Unless you are trying to debug an app do not enable this.
It's for developers trying to develop and debug their applications behavior.
MAYBE if u have rogue app installed it may help JUST for that app. But that's a BIG maybe. And then it could cause other apps to have to relaod constantly which will DEMOLISH battery AND performance due to higher CPU usage.

I usually choose close all acitive applications upon finish using the phone, so I guess this option would do this automatically for me? I've found if I leave certain apps active my battery drains way faster.

The developer setting for kill all apps upon exit is NOT the same as clearing recents. It isn't doing the same thing.
Which apps by the way would you say are "staying active" ?
You can check to see if it is those apps specifically that are causing drain by using apps like Gsam battery monitor (my personal choice due to its user friendliness) or better battery stats app. In Gsam battery monitor you can open the app usage section to see exactly which apps used esactly how much battery/CPU wakelocks/time held awake/background CPU vs. foreground CPU/ etc....
I would say that MAYBE for a very specific type of usage that this option may help in battery life. But it without a doubt will eventual degrade performance, due to more CPU cylces needed to fully open an app from scratch vs having it cached in ram. The setting is for sure meant for developers trying to debug their applications behavior and not meant for users to get better battery or performance. If it WAS meant for those, it would have been enabled by default. It will surely mess up multitasking, which is what android is really all about. TRUE multi tasking with apps running in background. So that is what would really depend on your usage I would think.

I think this usage suit my usage very well, I use my phone briefly for calling, maybe very rarely webbrowsing, or sometimes wechat, so I want an app to stop completely once I finished using it since I probably won't open it again in 3,4 days.... I am not those smartphone addicts that's constantly playing their devices.
I only use webbrowser when I was outside and need to lookup an address... no, I don't even use facebook.

I have noticed that im using up 2gb of ram. But i have only downloaded a few apps. No games. All the stuff i had before. My old phone was a little over 1gb total. Is this normal. Does the phone uses a lot of ram out of the box. Im thinking of rooting just so i can free up some ram. Not sure if that is possible. Im coming from a galaxy and very happy with this d851 g3.
Anyone having a memory problem ? Issues? What can i do?
Android always runs while using up as much ram as possible. Thats normal, if your phone had 8gb of ram, most likely it would also be using most of it up.
Makes app switching faster.......
All that bloatware runs in the background contributing to a high ram usage

Not completely true. I disabled most of the T-Mobile and LG crap on this phone and it's still using the same amount of RAM. It's Android's memory management.
I bet if the Android team could go back in time in the early days of system development they would have probably removed the ability to see free ram. So many people get caught up in free ram when the phone is using the available ram to the best of its ability.
Windows does alot of the same as well. Even though if you go into task manager it shows free if you actually look at your system resourses it shows alot of it is taken.
Unused RAM is wasted RAM.
Not sure about the whole 2g for 3gb thing but your system need all the rams it can use to keep your phone running smoothly. If you use ram cleaner (so they are call) you will notice your phone goes through a gitter before it it can pick up again. You look 5 minute later, its like you never clean anything.
and tmobile is surely 3g
Free RAM is wasted RAM.
Android uses RAM differently from say Windows. Android will use as much ram as available and when it needs more, it will free it up as needed. This is normal.
So yea i installed greenify and it made a **** load of a difference because i have like 40 games and a load of other apps. I have less than 1.5 gigs used now. And my phones way smoother and batterylife is good again

Don't worry you're about to see that battery life drop like a rock. Constantly killing apps will kill your battery fast. Greenify is a nice app if you have a crap phone but your G3 was made the way it is for a reason. What you think is smooth and fast is actually hurting your phone. Don't believe me, Google it and do some research. I do not recommend anyone using any format of task killer or ram optimizer on a phone that is current with the times.
Do I think the phone has issues. yes. When using it the apps don't close when ram is needed. Only fix is a reboot or kill the app but at times that does not work

Don't worry Jammol doesn't know what he is talking about. Greenify doesn't hurt battery life and performance like a task killer because isn't a task killer. It is completely different. I agree that task killers should be renamed to battery/phone performance killers but Greenify is very different.
First of all it requires your phone to be rooted. Assuming that it is, it uses special permissions from the rooted device to essentially freeze the app unless it is opened by the user. For example, I use facebook but only casually. I look at it once every other day or so but have noticed that the push notifications and messenger uses a lot of battery because it does a partial wake everytime it pushes a update which activates the internet and cpu.
The solution is to "Greenify" the app. The app still loads normally when I open it up although, because it is not in the ram, it likely takes slightly longer to load. Once it is opened, I can use it like normal and I get push notifications again until my phone's screen goes off. Once the screen goes off, facebook and all the apps that I "Greenify" are flushed from the memory and are banned/essentially frozen until I launch the respective app again. The only drawback to this is that you essentially never get push notifications for the apps but it saves a lot of battery if you pick the apps that you don't care much about/rarely use.
So greenify does work really well. Today my phone had 17% left. I it had 16+ hours of battery time total. I got 4.25 hours of SOT with sync on (with 3 email accounts getting push notifications plus other apps), GPS high accuracy, LG health automatically recording my exercise, and 1 hour of navigation with Waze. Basically I used my phone how I wanted and didn't micromanage my battery usage throughout the day at all.
I used 3 battery saving tools. 1. ART 2. Greenify and 3. Custom Kernel V002 from KAsp3rd. These three are very powerful together.
I hope that helps someone!
