kill tasks n battery saving

hi all,
i m new user for Nexus one, i wonder what is the best task apps to auto kill when the phone in sleep mode in order to save battery. My phone havent ROOT yet, shall i do it? After i have update the Android 2.1 i found it very good compare with iphone.
thank you very much

Killing tasks won't help to save battery... don't buy the hype. Android will manage your apps for you.

No killing tasks can help your battery. There are many apps on the market that are poorly written and drain battery.

Well that makes sense... but I don't run any poorly written apps. And neither should you.
If you absolutely have to have a task killer, just download Astro File Manager. You'll need a file manager on this phone anyway, and Astro has a built in configurable task killer and can also back up apps to SD.

I try not to. But sometimes I get curious and download some random apps haha.
I use Advance Task Manager since I bought it when I had a Cliq.
It works good when I need to kill something to restart it or if I need to do a batch uninstall.
Astro is amazing and no one should have an android phone without it.

Thks all,
If so, i shall just leave as it is and not install any of those task killer or auto task etc......
But anyway to min the battery drain since there are so much apps running on RAM when the phone is in sleep mode. My battery can only last for 8 hrs from 9am till 5pm (i am so distracted, i do turn on my BT and talk on phone for at least 100mins-150mins a day.)
Thank you

Keep the screen brightness as low as you can. Also having a lot of widgets can contribute to battery drain.

while this is true, I notice that android's threshold for closing programs is lower than I prefer. It seems to start closing programs at around 25 mb free (on stock kernel and rom) as reported by ES strong's task manager. At this level there is a noticeable amount of sluggishness on my N1. Of course this only lasts for perhaps 10 seconds or so as I am switching apps or whatever until android closes the processes to free up some ram.
I've read comments like yours many times, and I go back to not using one for a while thinking I must just be paranoid. Each time I return to the task manager because I get ticked about sluggishness.
If you manage your ignore list carefully to avoid closing stuff you actually want running in the background you lose nothing. The phone is fast enough that it loads apps quickly even if they're not sitting in the ram, so I prefer to hit the autokill widget once in a while or after using something like the youtube app or other resource hogging apps that I don't use on a regular basis.
I haven't noticed a difference in battery life, but the task manager improves my experience with the phone. It seems that as long as the free memory stays around 40+ I don't see the sluggishness.

Which task killer you use?

Advance task manager also lets you set a timer for auto closing all open apps except for the ones you have on your exception list.

Try Juice Defender,is free on the market and everytime you turn the screen to sleep it kills the background data to save battery and @ wake-up its normal again.Read the reviews.

I've got over 400 hours of uptime without closing ANY apps with a task killer, and haven't had ANY sluggishness. So if you're really noticing your phone slowing down (and be honest), then I'd exchange it. Frankly, I think a lot of people just "think" their phone is slowing down...

Cyanogen says don't use a Task killer!

Yeah, I'm sure you're right.. it's all in my head.

Couple of things OP:
1. Bluetooth is a battery hog!
2. How frequent do you have email update, weather update, et al set to?
3. Did you properly calibrate your battery meter when you got your N1? (Two ways to do it, 1) follow the in box guide and charge the phone before using or 2) run down the battery until the phone shuts itself off, pull battery out, put it back in. Now, without turning it back on, put it on the charger and leave it on for a couple hours past the green light coming on, take off charge, finally turn back on)
4. Do you have WiFi running? GPS? Streaming anything?
Have you downloaded any apps from the market just on a quim? There are some pretty bad apps that will never close until you uninstall and do a soft reset, and sometimes uninstall again.
Killing apps is actually going to hurt your battery. It takes more juice to power up the CPU to open an app then it does to hold it in the RAM, unless it is a crap written app that keeps running, and running, and running... but you shouldn't be using those apps anyways.

It most likely is... even when apps sit idle in RAM, the CPU usage for them is 0% in almost every case. Like I said... I don't have those issues at all, so it's either in your head or you have a dud.

Advanced Task Killer Questions please

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.

Any suggestions for a good task manager?

Hello, all. I am currently running the free version of Advanced Task Killer, which seems to work ok, but there has to be something better. What I've noticed is, that after a reboot, the app will tell me that I have about 240 MB of available memory when all apps are closed with the exception of the task killer itself.
However, by the end of the day, after I've opened and closed a few apps, sent some messages and emails, made some calls, etc, the task manager will show significantly less available memory available. It could drop to as low as 135 MB with all apps closed with the exception of the task killer.
This leads to me to believe one of two things:
a) The Task Killer is full of it and it does not have an accurate read of how much memory is actually available.
b) The Task Killer is only able to "kill" certain tasks while others remain running in the background and it does not show that the app(s) are actually running.
Honestly, I think it is option B, because I do notice that when the app tells me that I have less than normal available memory, the phone does tend to function slower and lag a bit. Nothing that cannot be fixed by a powering it off and on, but I am hoping that someone knows of a good app (even if it is a paid app) that will actually bring up ALL tasks running and kill them. I've also noticed that even with this task killer, Google Talk (which I have never used) always remains open in my phone and I have to manually go into into the settings and turn that off.
Any suggestions?

My suggestion is to not use one.
I do use Autokiller though which tweaks the thresholds for Android's internal "task killer".
It's best to let Android do it's thing.

Really? Do you mind elaborating on why you feel that way a bit so I can understand? Because I do notice that when the I am running a bunch of things at once and I use this app to kill the tasks, it does improve the performance of the phone.

I can understand why some people say you don't need one but I do think it is necessary to have it installed for when you do. I'd rather kill apps than pop the case, battery cover and battery to fix a frozen phone.
I have some GPS apps I run occasionally that after exiting them they don't turn off the GPS or lock the GPS on and drain my battery. So for those apps where the developer didn't put a close buton on the menu it helps shut them down. I don't know why Google Market doesn't require apps to have a close option.

Because users shouldn't have to manage their own memory. Apple folks already love laughing at us for that very reason, and even though it pains me to say it they're absolutely correct.
I can certainly buy the argument that task killers are nice for those occasions when something does go haywire and it needs to be forcibly killed, and I can understand using one just because you're curious and want to see what's running and how much memory you have, etc, but beyond that I find that they're unnecessary. My EVO runs very smoothly without me manually intervening, even after many days of uptime with many apps running.

Wow! That's detailed and a lot more than I bargained for....lol. Thanks! Good thing my phone is rooted and I was able to use it since I never did the recent update to the 1.47.xx OTA update and I'm waiting for a fully functional version to be released, but there is a lot of stuff on this that goes well beyond my basic knowledge. Apparently, my phone has 89 processes running with no apps running (according to Task Killer) and only one widget running and the CPU is fluctuating at 10-40% usage.
Interestingly enough, but apps report the same amount of available memory......EXACTLY the same. So it can be assumed that both apps provide an accurate figure of available memory.

I would advise against using a Task killer. Android has its own memory management, which works extremely well on the EVO, to be honest. The latest update (1.47) feels like its makes the EVO perform much better and allows it to be more efficient.
If anything, I would suggest you read this thread about an app called Autostarts, which isn't a task killer, rather a startup manager that can be tweaked to do many different things. By not allowing certain things to start up when your phone boots, you'll have more memory to begin with and Android will be more efficient in memory management. I would try Autostarts before using a task killer.
Hope that helps.

I agree, but having to run a task killer is a small price to pay to not be part of the iPhone bandwagon crew, IMO.
Are you running a custom rom on your phone? I just have a rooted stock rom. Maybe that's why your phone can go days without the performance being affected? I still have all the bloatware on mine, and I've put off removing it because I am still a noob at this and I'm in the learning process. I wonder if the new update that was just released improves this aspect of the phone at all.....?

Thanks, I will definitely look into it. All advise is appreciated as I am very new to all of this. You answered my last question on my previous post with this, too.... I can't wait for a fully functional rooted OEM rom to be released with the goodies from the new update to try it out. I'm hesitant to update my phone now and lose superuser as I use the WiFi tether a lot.

Apps keep opening in background

I have a lot of apps opening up in the background on their own and eating up my memory. Things like qik, skype, city id, vz navigator open on their own even though I barely use them, if at all. My free memory keeps dropping down to around 30mb. Is there anything I can do?

The best remedy I came up with was rooting my phone, and then installing Titanium Backup and Autostarts. Titanium can freeze the apps you never want to use like some of the crapware that comes preinstalled. For the apps that you do use, but don't want automatically opening all the time, you can use Autostarts to choose which conditions must be met for the app to open, or not open in this case. For both of those applications, you need to be rooted, and unfortunately that's the only way I know of to stop some of the apps you mentioned (especially Skype and CityID).

You can root to remove the bloatware, but that's it. Also, memory on android isn't the same as on a PC. With a PC, clear memory means a faster system, but the opposite is true for android. Because of the way it manages applications, you want to keep the memory as full as possible.

This is the answer. There is a difference in night and day with my X since installed Autostarts and Fission.
If you install Autostarts and use Advanced Task Killer you will be able to kill the apps and they won't continue to run/open in the background. It's extremely worth it.

Search android task killers on these forums. Then listen to the posts and let android do its thing.
Task killers bog down the system because these apps are shut down while attempting to do something (sync, send data, etc). The app then realizes that it needs to complete the process and restarts. This continues over and over hogging your cpu resources and slowing down the system.
Stop paying attention to the free memory and open apps. This is not an iPhone.

You're missing the point. Autostarts doesn't allow the app to start in the first place so it doesn't bog down the system or hog resources.
Correct me if I'm wrong but is it not Gingerbread that has added the addition of a task killer.
It's not about the free memory, my phone runs faster. I can tell a difference.

It's possible we may be talking about different things.
I'm pretty sure closing Angry Birds when it's still open because I Home Screen buttoned out of it won't make a big difference.
If you're referring to closing services while they're running, it's a different story. I skimmed through the article, it looks interesting, but I honestly fail to see how closing an app that's running... even one that might be doing something I don't want it to (like using GPS because it didn't close when I back-arrowed out of it).
When I bought my phone, I installed Weather Bug. Weather Bug kept trying to get my GPS location while I was at work. My phone barely made it through work. Anytime I checked the weather, I had to close the program through a task killer, or I'd have no battery because the phone was trying to use my GPS all day.
How does not closing that save my battery?

It's possible we may be talking about different things.
I'm pretty sure closing Angry Birds when it's still open because I Home Screen buttoned out of it won't make a big difference.
If you're referring to closing services while they're running, it's a different story.

That's not a valid comparison. The android system manages apps, but it doesn't monitor everything that they're doing to prevent a runaway (like weatherbug). Actually read the article, then comment on it. And you do know you can turn gps off, right?

I happen to like GPS, and as long as I don't have any runaways, it doesn't drain battery since it's not used.
I'm just saying, for programs like that, Task Killers are great.
I'll read it tomorrow most likely.

I tried Watchdog and a few other task killers before finally shelling out the money for the full version of Titanium. I found that often times, the biggest cpu hog and battery killer was the task killer itself since it has to be constantly running in the background. For apps that you use on a regular basis, the best remedy for saving battery life is to just change the update interval period. By default, a lot of widgets (especially weather) update every 15 minutes, which can be a little tasking on system resources at times. I set mine to 1 hour and that helped tremendously. The main reason I went to the full version of Titanium is because it accomplishes what task killers can't by freezing apps to deny their access to open at all. Instead of removing the bloatware like CityID, VZ Navigator, and others, which will keep your phone from receiving OTA updates, just freeze them and you'll never have to worry about them. Autostarts takes care of the rest for me by allowing full control over the condition changes on the device which trigger certain applications to open. For example, I may use Google goggles occassionally, but I don't want it to automatically open in the background just because I enabled GPS. Before rooting my phone, I would normally average between 14 to 18 hours on moderate usage (with a task killer running I might add). Now, with those two applications managing things more meticulously, and chaning the update interval for all of my widgets, I get around 30 to 36 hours easily.

[Q] Are task killers safe for your phone?

I've read some posts and people said they are killing more battery.Other people said that they're good.So are they safe for your phone,or they can harm it.
I've used task killers since I got my phone and hadn't got a problem.

I found the answer by myself:

I tested ATK with 2.1 2.2.1 2.3.2 using my phone (Gps, 3g - ON) with same apk on board each ROM and modarate killing and my battery last longer without ATK.

I got rid of my task killer.I will provide some feedback after some use.Thanks for the reply by the way.

its good n safe if u use it wisely
i ever killed a running system n my phone become frozen

I've been using AutoKiller Memory Optimiser which utilises presets and works well with rooted phones.

i think not

Task killers aren't necessary for Android 2.1 and above. Google has optimized the system so that if you run out of memory, it will start automatically killing unused apps in the background. Even though you might see that only around 20MB of RAM is available doesn't mean it's a bad thing. It means that you can load up your recently used apps more quickly as it is already "cached" in your memory.
Killing apps may also disrupt other system processes that require it to run properly. However, if you want to save that extra battery then a task killer is good to use. Otherwise, task killers are not necessary. I would recommended downloading an app called "Watchdog" in the market. What this app does is monitors your running apps for any memory hoggers. This allows you to kill that app or uninstall it.
This is just my thoughts and may not be entirely correct. Anyone wishing to correct me is welcome to.

Thanks for your reply.I also think that they aren't necessary.In the link above I read that task killers are dangerous for your phone.They are slowly killing your CPU and after some time the phone may start to crash.

Well i'm using a taskkiller and it doesn't do any harm.. And I think it makes my battery last longer.. But that might just be some kind of "placebo effect"

I personally don't use them on my phone, but on my tablet, I use them as it can get very slow without it.

I also thought that they were great,but after doing some research I decided to remove my task killer.My phone is working as smooth as before.But that's just me.
