Hi
Ive just got this app (really to save myself some battery time)
On launching for the first time it presents me with a whole bunch of stuff including my clocks
Now i'm sure this maybe a pretty dumb question but if i kill the htc clock App will that stop the time and weather updating correctly? (i have my weather set to update hourly) and also if i kill any app like K-9 or Peep (that i have an update schedule set for) will it stop that schedule till i manually launch the app again or will it auto launch when it reaches the sheduled update time?
Sorry for the (potentially) stupid questions
Cheers
The only thing you're going to achieve with using a task killer, is lowering performance and causing even worse battery drain. If that's what you want to do, fine, but otherwise, I wouldn't bother if I were you.
Here's why:
Android's memory management is nothing like Windows Mobile. Applications you've finished with are MEANT to stay in memory until they really are completely finished with, and just because YOU aren't using them, doesn't mean the phone has. If they've been inactive long enough, or some other program needs the RAM, Android will tidily close them down.
If you close them prematurely, then Android will have to load them back up again, so that whatever was using said program's services, can continue to function. This noticeably affects phone performance, and puts an extra load on your battery. Do you REALLY want to do that?
I'm not using any task killers, and my phone runs great, and battery is up to 2.5 days.
Hmm interesting, i might try that, im killing all instantly and repeately, thanks for the tip

Thats correct.
I installed it on the phone, and the battery was empty the same night
Uninstalled it, and all works fine now.
Greetz.
would an app like task panel work?
you can add apps that are system apps etc to the ignore list and have apps such as games on the force to kill list or is it just best not to have any task killer apps installed at all?
its strange that there are so many task killer apps and its bad to run on your device. There must be some reason as to why there is an app for this purpose?

They exist, because people think memory management on Android works like it does on Windows Mobile. It doesn't, and never has. Think if it like the so called "memory manager" tools you can get for XP that claim to be able to free all your RAM and speed up your system... Every single one of them is nothing but a placebo designed to part you from your cash, and often end up CAUSING problems, just like task killers on Android do.
Avoid them.

Guess thats a good enough reply lol
task killers can work fine, but you need to know what is running and what is using it.
for example, if you have the music widget on the homescreens, then the music player process will be opne in the background.
likewise friendstream will keep people, facebook and twitter open in the background.
if you kill those processes, they will just get opened again.
As long as you are careful, using task managers will not decrease battery life, you just need to know how to use them properly. randomly killing everything in the background is NOT the way to do it.
and you should never close clock if you want your alarm clock to actually go off!!
Might be worth making a list of what apps should be ignored and what apps can be forced killed?
When i had an app killer installed, i used to only force kill games and sat nav apps, the rest i asked it to ignore but after reading this thread, i decided to delete the app killer app =)
Ive put a bunch of stuff like clock, weather, Peep and facebook etc on the ignore list and have used the task killer to only kill off frivolous apps like Spark (for xbox friends) streamfurious, photos etc...Nothing Major!
I unhooked my phone from the power at 7:30 am on the 13th April, its now 16:36 on the 14th april and it still has 30% of the juice left, and i always have wifi and mobile data connection on too...phone is always left on with facebook connecting ever 4 hrs and peep once a day and mail set for every 2 hrs (besides which i do check and update them manually a couple of times a day)
I'll try all this without task killer installed and test how long the phone can run before charging
As you say, it could well be a combination of the battery coming up to speed and a placebo effect.
However, surely it cant do more harm than good to kill an app like Spark !
However, im no Phone Genius so im sure someone will soon tell me that im completely wrong
But so far so good....like i said, ill test things without task killer installed
I've stopped using the task killer now and my battery life has improved very noticably.

im not so sure about this.
im using a task killer when i want to close the browser or something using internet, as we all know internet drains a lot of battery and even if the browser or market is in the background it still probably has some active connections = draining battery

If you want to close fast the browser or any app, you should have a try at taskOS and launch it with the search key whenever you want...
Binned this app in favour of Juice defender, my new battery saving app of choice, seems to be working as it should too...nice

but then that works pretty much like a task killer
can anyone correct me about the apps i.e. browser using internet while not active(in background) is this true or not? of course having the sync/updates turned off
Task killers can be handy for those times when apps seem to have crashed but aren't forcing close. for example, i've had times where ebuddy just doesn't want to even try to sign in. Task kill it. Try again. all is well. And last my internet browser wouldn't let me click any buttons. Again, killed it - restarted - all is ok.
I've had to use such an app countless of times due to unwanted/unneeded apps running, hanging FCs and black screens, checking/closing net related or sensor using apps, and numerous times when 300KB apps wouldn't install citing 'low memory' when I have more than 70MB free, but it was the RAM being near full causing FCs in apps like Market, and halting the installs. I only use Androids built-in TaskPanel widget for this though. Everything routine is set over to the ignore list so that I don't accidently hit and close that (single hit closes the app). Additionally I use this app to check and to switch to an opened application that is running (when it's not in the recent list).

This is the route I've taken naturally. I'm using jkAppSwitch on my longpress search key, mainly used for switching but can be used to kill problem apps.
Full task killers are being proven to be useless on the Desire.
I would recommend using an app that monitors the cpu usage(watchdog etc.). This way your can see which apps put a drain on your phone.
Thank you for the information. But I do notice a considerable improvement in battery power with Advanced Task Killer.
I hope someone can provide me an answer.
I have seen people saying you need one and others saying you dont. Even Android devs posted a blog a few weeks ago saying you really dont need one. I installed ATK and it showed things running that made no sense to me and way more then what my running processes showed under my settings, how is that possible?
task killer vs no task killer... its like automatic vs. manual transmission. many new cars have automatic, but than does not mean that its better than manual (tho sometimes it IS, but rarely).
i do use task killer, but only when needed. sometimes i like to kill my browser to clear out the history and open windows, and once in a while i get an app that's simply not behaving.

This man speaketh the truth. There's no way to end some apps in Android, but to use a task killer. Browser/Internet is one of them.
The more I deal with Android, the more I realize how unpolished its code is. For example, to decades old WinMo.

Thanks, I checked those (or like those) out many months ago, when I was playing with N1.
I have the option for one (SystemPanel), but it has no auto features and I never use it. I use it more for monitoring my device and battery usage.
Advanced users are going to use them. Performance starts to suffer in the system when memory drops to around 100 and gets really noticeable sub 50.
Generally I have 200+ free because I'm on froyo so its not as necessary but on stock the htc **** is just insane. Damage rom does a great job of taking stock and making it useable.
I always used one until FroYo, now I have generally around 260mb free. It's perfect
I was using one (Advanced Task Killer) and finding it frustrating as it would show apps open that I had never used. I would kill them when I found them and then I set it to autokill when the screen turned off. Didn't work, they would still be there when I turned it on. I finally just said the hell with it and uninstalled it. Since then I've noticed that the phone seems to run a lot better with less lag. I like it much better since I dumped the task manager.
I don't use one and normally I uninstall the default browser (it annoys me i cant exit it) and install Dolphin HD as my default.
I used a task manager when I first got this phone, did more research as I tweaked the phone and read about why not to use a task manager. So far its been a week without a task manager and I'm noticing better battery life, and while I don't notice an improvement in performance of any kind, I also don't notice a drop in performance.
I think I will be sticking with no task manager for the time being. Its also really nice not having to worry about what's running or not, and having to run the task manager to exit applications or what not. Its also one less program I have to worry about.
Is a task killer needed on froyo or can it manage without one?
If you dont use one, does the list of running apps get larger and larger?
i heard task killers arent good but eh, i keep one just in case
I haven't used one on Froyo and it runs fine.

Android can handle the tasks better then you..dont use the task killers they are bad for the long run..
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
Specifically Froyo is more aggressive than Eclair. The tasks are killed by the system more often than I'd want to.
if i don't use a task killer my browser will eat up all my internal memory and will stop my phone from getting text messages..

Same here! Used a Taskkiller nearly every day on Android 2.1
I still have a light one installed but I actually never kill any app.
I sometimes close some services with Applications / running services thing.
Apps like PingChat! for example.. apps I don't use regulary

The built in running tab in 2.2 is better than any task killer i know. Its under manage applications. you shuold see four tabs "Downloaded\Running\All\On Sd card". Why the need for a third party task killer?

1:0 to you If you need to use it THAT much - perhaps you're better off using task killer for that. Did you try setting up old-school Apps2SD to free some internal memory?
I don't use any task killers. But I do use system panel which is the best out there by far.
The browser gets large over time, but if you just go in and close all your windows, the browser releases all the space.
if task killers are not needed then why when I open the task killer there is always a whole page of tasks running?

Because those processes barely use your system resource, so there's no need to close them in case you might want to use them any time again.

They aren't really running. Most of them don't have any system usage when they're idle. They're just "running" (not really) to start things faster.
When you kill them most stuff will start slower and this is using more battery
I've found that task killers generally hurt more than they help, draining batteries faster for little benefit.
Furthermore, in the rare situation where there really is a rogue app eating up RAM, you can kill it using the built in Running Applications tab under Settings.

Because that's how android functions, it purposely loads those things, and they are static, frozen in the background not using any resources. By fighting the OS to keep killing those, you waste battery cause the OS will just keep opening them and the task killer will keep closing them, over and over, killing your battery.
You guys can test this yourself using the app system panel. Enable monitoring and see what's using your CPU, you will see exactly what is using resources and why it has no effect on your battery.

Let the kernel do the work. Updated stocks are pretty good, but I like Netarchy's kernels better.

The way that 2.2 manages memory makes having a task killer almost unnecessary. However, you might want to keep one handy just in case you get one of those buggy apps that keeps on draining your battery or makes the phone unstable. I personally use SystemPanel app: nice interface and monitoring options for battery life, history, uninstaller and backup-to-sdcard (archive).
Why would you ever want a task killer?
I would like more input on this. I ditched them on my Hero back when I ran CM6, mainly due to the fact that they actually slowed that phone down!
But it seems on the Evo, killing tasks seems to save much more battery life. Or am I just dreaming?...
I have stopped using a task killer since going to 2.2 and have never looked back.

You're dreaming.
Keep a passive task killer around if you like that you can use to kill programs that go completely nuts. E.g. use it to kill a game or app that has locked up or just isn't working right. A passive task killer is one that doesn't actively go searching for apps to kill on its own - one that you must manually tell to kill an app.
If you like, I suggest you try Watchdog Lite from the Market. It occasionally checks your phone for programs that are gobbling up tons of CPU time that may be an indicator that an app isn't running correctly. It still won't actively kill the app though; it just warns you and lets you choose to kill it.
Task killers with Android 2.2 are usually a dumb idea. 2.2 does not have a traditional "kill" command like earlier versions of Android. In 2.2, the same command that would have killed an app is now just a restart command. Instead of the app dying and going away, the app dies and then restarts all over which uses up lots of extra CPU cycles to restart the app. It's only going to save you battery if the app in question has gone haywire.
If anything, get an app like Autostarts that lets you control when apps are allowed to start.
I have systempanel lite.. gives you some nice OS info also gives you a widget to kill apps on demand. I don't use it much but sometimes if I feel my phone is getting a little sluggish. You can exclude all the htc/system/gmail apps etc from being killed. But I agree, do not have a task manager running all the time.
SystemPanel is great. Aside from being a task manager it also is a system monitor and is very helpful in tracking down problematic apps and system processes.
Autostarts is also great, I have mine configured so pretty much NOTHING runs without my say so.
Hot Reboot is pretty slick too, when your phone is starting to slow down and act sluggish. Just do a quick ROM reboot (10-15 seconds TOPS) and your phone is as good as new.
Why not just use the built in one? Settings, applications, manage applications, running tab?

I use System Panel to moniter my phone and AutoStart is a great app to jeep apps from launching themselves again after you close them out. Throw in startup manager and you have a great trifecta of apps.

Yes, this is the way to go. No extra programs needed.
The taskmanager that comes pre-installed with the phone seems useless...
Reason being is that when it's used to close apps to free ram, seconds after it's as it was before...
Supposing my used ram is 474mb. I then clear the memory at which then the task manager reports used ram as just 273mb.....
When checking the task manager literally minutes after it will then read 474mb or higher.
This is even when the phone has not been touched & was left on idle.
So please tell me the point in having a task manager that kills apps which then simply open again moments later....
Task manager exists to Effin close the apps for good, not have then "tabbed-out" and sit there and drain battery / Ram. Man, some people are oblivious.
Edit: abd apps dont open by themselfs after, geez. Its the system (THE PHONE) that takes from Ram to actually /run/ and function

Yes I know, but BazookaAce referred to a task killer, a third party app in which I didn't mention.
I simply stated my opinion and I did not have a go at anyone & neither was I rude.
So for a simple opinion I get trolls having a go at ME making statements such as I know nothing about android and being oblivious.
Seems you can't express your own opinons without getting trolled on...
Why must people be so rude and have a go at you?
I have a right to be angry...
If someone disagrees with my statement, then let it be. I'm not saying I'm right or wrong but If I disagreed with someones statement why should I become rude and fight?
Why is it so wrong if I simply stated I feel the task manager is useless? There is no need to get rude...
what the task manager does is kill everything except for the bare OS. then when you go to home, it will rebuffer all your widgets and icons back into the ram, and will reload any background processes that are required to run the widgets.
occasionally when you run an app and close it, it will leave the process running in the background, taking up ram unnecessarily. an example would be something like tap tap revenge, android market, music player, facebook, the crappy polish media player that came with my phone even though i never used it, etc.
normally, unless you have a task killer or task manager app, these apps will remain hogging up ram until you kill it. even if you use the market or music player once and then close it, it may remain running or may have a background process that remains running. what clear memory does is it removes all of these little annoying processes from the memory and just restores the OS back to its bare ram usage again.
this is useful for when you want to play a game or use an app that requires a lot of ram (ie. dungeon defenders) and you dont want it to crash on you when youre making an ingame purchase because you ran out of ram. you can clear your ram of junk first and then run the game, leaving you with more ram available for the game data.
task killers are silly because people often program them to kill apps that are designed to reopen themselves anyway, which puts the app in a reboot loop that drains more battery.
if you want to permanently stop a process from hogging up ram, you'd have to root your phone, run titanium backup and freeze the useless processes.
Thank you so much Souai for your response, you provided some useful information with regards on how task managers work...
Unlike a few others who were unhelpful I appreciate your post and detailed explanation.
Will hit the ''thanks'' button.
As for Titanium backup, I've heard of it but not tried it. Once my phone has been rooted I will give the application a try.

Well i can tell you from experience that task killers DO work.
Before i put the phone in my pocket, i run it, saves battery drainage.
And when the phone begins to lag, i run it, and it runs smooth again.
So whatever all those articles tell you, i experience the opposite.
P.S. I'm rooted
