It started driving me mad. If I minimize browser, I can't be sure it won't close. Not only minimizing for longer periods, but short ones as well - wanted to reply an sms when a page was loading, but when I got back to it, it started over. And all the loaded tabs were gone! Saving states my ass, it takes time to load a page from zero and only the active browsing window remains. How to make this "multitasker" multitask?
does this also happen if you return to the browser by holding home?

Yes, that's the only way I switch betwen apps.
Have you installed the 'system-based' taskiller mod by any chance (you know, the one that was announced here that automatically keeps memory free by modifying the default thresholds for killing apps)?
If so, I reckon that's the issue! Either that, or you have too much running, so popping the browser into the background makes it a background task and it gets killed cos you're really short of RAM.
Let us know if you have used the tweak though...
@kengdong...
it doesn't matter how you change the apps.
For android it's the same, whether you tap an icon on a homescreen/list or whether you select it from the "task switch" thing... all that does is listing the last recently used applications but still tapping them results in the same internal action.

I've had pretty much the same issue since I got the phone back in November (I guess I've just gotten used to it by now). I'm never really sure when I switch back to the browser if it will retain the page loaded and any other windows, or if it will reset, close the other windows, and have to reload the active page. I'm on the stock Telus ROM, no custom ROM, not rooted, no tweaks, nothing extra (I've been waiting patiently for 2.1 to come out before messing with custom ROMS).

No, I have stock rom and I have never used any task killer or related app / tweak.
And I don't run too much stuff.. only music player, messaging and sense's facebook perhaps. If music player is paused, why can't it quit it instead... I prefer multitasking of my past htc s730 which had like 7 megs of free ram after booting.
Even after a hard reset, this behavior remains.
i dont know.. it works fine for me....
1.. maybe there is a setting in the browser.. to always refresh.
2.. you have a repair issue.. Need to take it in to your local service provider repair center. Let them see your issue.

Come on, it's no hardware issue. Most of the time the browser stays, but u just can't be sure about that because it sometimes just closes. I think that it's an issue with Android's STUPID memory management, which also has a scheduled "quit all" script.
Yesterday I opened up a few articles on the browser and decided to read them later. This morning they all remained and I was pleasantly surprised I could read them. This very moment, though, they are gone by now even though I haven't quit the browser - probably that 'quit all' script kicked in.
There could be something in settings, where you could chose apps which would not close ever unless quit..
I would love if Android apps were quitable without any automatic mem management.
Suggest to grab AutoKiller or MinFreeManager, which are just frontends to Android's memory management (also they reapply settings at boot time, as the system file that's being modified is reset every boot.)
See what your current settings are, and lower them (e.g. use "moderate" preset). Just search XDA for autokiller or minfreemanager for more info.
Pressing home should only move that application to the background (pressing back should close it).
If you are pressing home and applications are still closing then there must be a task killer of some sort in place closing it for you.

No task killers, tasks dont neceaarily close, its juast that u cant be sure they will remain in memory.

Yes - it's the standard Android process management rather than a 3rd party task killer.
I guess the browser is given a low priority and is one of the first apps to be killed.

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

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?

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...

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.

I don't think it's a problem with my phone. If you don't notice then good for you. I notice it and it bothers me. Your finger pointing is neither helpful or needed.
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.

From what I understand the MT4G is supposed to do a job on it's own of closing most applications most of the time, better then any other android had (at time of release anyway). I suppose if you think it's that big of an issue you could download a task killer, but I've heard over and over again to not use on on the mt4g because you just don't need it. That's just what I heard though.
Could be wrong, wouldn't be the first time.
Is there a setting for that then? because nothing closes on my phone
yeah i agree on NOT using those task killers. i have seen many posts from devs saying they cause more problems then there worth. interfere with apps causing force closes and some other thing that i cant remember off the top of my head.
Google up "Why you shouldn't be using task killers with Android", read, educate yourself, and stop doing unnecessary things with your phone. Understand how things work before you attempt "making them work better", and screw them up in the process.
Ok sounds good, but why then when you get rid of the bloatware like "amazon mp3" by disabilig them, do you get improved battery life? What am I missing?
You don't. Battery life won't be bothered by having or not having Amazon MP3. The only thing you get is more memory (which isn't used anyway) and more space on the /system (which isn't used anyway). Additional thing you get that IS used - is less cluttered app drawer.

Task Killers do more harm then they do good. any developer, any coder, any one with any Android knowledge will tell you "you do not need it, and they do more harm then good". In fact Google themselves has said that it's not worth it. and the dev team @ Cyanogen will not accept a event log for trouble shooting if you have used a task killer.
But the reason we delete bloat ware is to gain that memory for other applications and data. no all apps can be stored to the SD card and they do leave a foot print on the phone. So we delete them to gain the space back.
Android phones are Lunix based computers which can multitask lightyears better than any current windows based computer system, phone or server. They were designed with this very principle in mind. In fact if you have ever used Ubuntu 10.10 they have a 4 "work spaces" where you can do different stuff simultaneously. similar to the "home screens" on android.
as far as them "running" in the background they are not absorbing any data/battery/resources from your phone. They are setting in a "frozen" state until you open them. In fact, if you didn't know this, if you press and hold the home button you can access recently open apps. It keeps them in the "frozen" state so if you switch back to them they'll open where you left them.
Thanks for all the comments. But I don't need convincing on the task killers; I understand they're worthless. My intent was to find out how to make my phone perform better (battery life-wise). And although I think I have a better understanding on how android handles apps it also just confused me.
I used to get 8-10 hrs max on my phone and basically have to charge it all the time. Since I temp rooted (permroot isn't working for me) using VISIONary and disabled a bunch of apps using Terminal Emulator, I'm sitting on 23.5 hrs off the charger right now with 45% battery left!!! And all I did was disable apps. So I'm mad confused how I'm getting so much battery life when the only thing that's changed in my phone according to you wouldn't change anything.

battery life has alot to do with your social networks, and syncing. If i turn off everything, and turn the screen brightness to about 25%, i drop about 2% per 5 hours. So it really depends on what you disabled, and if they were absorbing any resources on your phone.

That is correct. However, there is one situation in which I do end apps, and that is in the case of resource-intensive, 3D games. The MT4G has so much RAM, that even games like NFS Shift, X-Plane, and Jet Car Stunts never close. They stay running in the background forever, which is unnecessary. So I'll close those, but no other apps.

So Samsung for whatever reason, decides it's a good idea to include an easy to access task manager with a giant "kill all tasks" button in TouchWiz. It seems like everyone I know, that has a Galaxy S II, has adopted a certain behavior due this. What they do is, every time they put their phone away, they will automatically go to this task manager and kill all tasks, before locking the phone. When I ask them why the hell they're doing that, the answer is usually something like "wasting battery blah blah blah" or "wasting CPU blah blah blah"... NO!
For starters:
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
http://lifehacker.com/5650894/andro...ed-what-they-do-and-why-you-shouldnt-use-them
http://www.infoworld.com/t/smartphones/myth-android-devices-need-task-killers-609
http://androinica.com/2010/05/googl...-imply-task-killermanager-apps-are-pointless/
People that are doing this, educate yourself. And Samsung, well done for encouraging this.
Just because a task is in memory, doesn't mean it's doing anything, and certainly doesn't mean it's using up battery. If it's staying in memory, it's because there's no need to release it just yet. If you start it up again, it will already be there, and load up faster. The alternative is, you keep killing it, and every time you run it again, it will have to reinitialize and reload everything. Which option do you think is actually going to cost more battery?
The whole thing with people saying "oh no it's using CPU, i must kill it"... what?! If it's using CPU, it's probably doing something. Why the hell are you killing a process while it's in the middle of doing something? Do you not care about data integrity at all? It could have been in the middle of syncing, or in the middle of a write operation who knows.
If you run other applications and your memory runs low, then Android will close it. And it will close it properly, as opposed to you force killing it, denying it of any chance to clean up.
Obviously there are rare exceptions with dodgy programs. But most of the time, the tasks being killed are system apps, or trustworthy apps, properly written by Google or Samsung.
If you're not a developer, you probably won't understand the whole Android application lifecycle.
http://developer.android.com/reference/android/app/Activity.html
By force closing an application, you're not allowing it to run its onStop() and onDestroy() functions. This is where apps do all the clean up, releasing resources, unregistering things, closing connections etc.
Do you do this on your PC. Open up Windows task manager, and just kill any task that's using CPU. Or hell, just kill all tasks every 2 minutes! Good luck with that.
This has probably been said hundreds of times, but a lot of people i know are getting GSII's and I see them doing this constantly. It's stupid. Do you really think they designed the operating system so that you have to kill everything each time you touch it?
TLDR: Stop "killing all tasks" (unless theres actually something wrong) and well done Samsung for encouraging this. Just stupid.
Damn your right, I never used a task killer on previous android phones, but for some reason I have got into the habit of doing it now. So I'm going to kill that habit. Well noticed
Well according to the user guide (the full one from Samsung's website)... though personally I don't bother killing anything
Use the task manager › ›
Your device is a multitasking device. It can run more than one application at the same time. However, multitasking may cause hang-ups, freezing, memory problems, or additional power consumption. To avoid these problems, end unnecessary programs using the task manager.
1 In Idle mode, open the application list and select Task manager → Active applications.
The list of all the applications currently running on your device appears.
2 To close an application, select Exit.To close all active applications, select Exit all.
i like the placebo effect and stop telling me what i have to do or not to do!
your writing style is to aggressive, stop being aggressive!
For me, it is worth to have the clear memory option because I already faced the glitch or bugs program which cause my phone to run constantly at 1.2ghz and this will cause my phone become extremely hot. I can't see what application is running but for some reason, the cpu gone crazy. It drain battery in no time. With the simple one click button, I can closed the programs without need to restart the phone. Yes, generally I will let the android system to handle the application by itself but I still think it was a good moved by samsung to have task manager if we use it in proper way...

Well it's not all that bad, with 2 cores one core can easily come into a deadlock and the device will continue to function albeit much slower and consuming a lot of power, when this happens in the taskmanager the processes are listed red
Thanks ever so for much for this post I have just got my first Android phone and thought by doing this it would increase the battery life a tad but did kinda think it was a bit daft having a system that required manually killing tasks. Coming from a Windows 6.1 XDA Zest I am still getting my head round an OS that's doesn't require hours on Internet to work out how to do things.
Sad, but true, I was getting onto Android from Symbian, and first thing after I realised that I do not have option of killing all apps, I have installed the task killer and kept using it for like a week, then I've read one of the articles about it, that its wrong, and that Android is not working as Symbian nor Windows, so I realised that I dont need to do that... unninstalled it and not using it at all since
You don't need Task manager / killer if only all android applications are developed by good programmers that implement Android application lifecycle properly.
The problem is not all applications are developed this way. Some application may buggy / in beta stage that still consuming processing time even they are in background.
Task manager is still useful to close nasty program manually. But I do agree, auto-kill is useless and can cause battery drain and system instability.
Yep .. it's mostly services what eats battery. And there is poor control over that. It would be interesting to see what service was active at what time, or even how much battery did it use. All battery discussions are about guessing what is running in the background and how often and how much. We should not guess such things.
As far as I'm concerned an in built task manager is just as important as an in built modem right now. There are far too many unstable applications out there that hang up and Android can never fully deal with them(despite what research may or may not have been done in the past).
I have a few games installed on my S2(namely Pool Break Pro & TNA iMPACT!) that crash quite often and require the use of the task manager to manually end those programs(they are in the task manager highlighted in red when they have stalled).
However, what I will say is that the button to clear memory in the RAM manager really shouldn't be there at all. The task manager alone is more than enough to manually exit necessary apps that crash and stay open for no reason.
I like to have the ability to close programs easily at hand. It gives me better control over "rogue" apps. I only use it for a few programs though, like the Engadget app. It seems to be poorly coded, often using 40-50% CPU when running in the background.

I like it because it lets me close frozen apps quicker..

Lol yes. Not to be taken too seriously.
Force closing apps with the task manager when somethings wrong with the phone or closing broken apps makes sense. I'm just talking about people that instinctively press the close all apps button every time they use the phone for a second. It's just silly. Basically doing what those automatic task killing apps do.
I use to kill opera everytime i'm done with browsing because even in idle mode the phone gets very hot when opera runs in the backgtound. But after these explanstions i stop force killing every app

If a program is badly written and won't stay idle, then kill it.
I am very selective about what I install, and never kill or need to kill anything.
You have 1 GB of ram on this phone. If you want best battery and speed, don't kill anything. loading a running app from ram uses less power than starting from scratch and booting it from nand, then starting it up.
So if apps are well written, don't kill them. If stuff stays around causing drain, kill it individually but find a better app
This thread is spot on... for the most part. Like Pulser said, there are apps when idling/cached, cause detrimental effects like the one I detailed here causing your phone to stay Awake constantly and draining battery:
http://forum.xda-developers.com/showthread.php?t=1094666
ATK isn't the most elegant method, but it allows you to put everything else on ignore and have it actively kill the apps that love to stay cached and cause issues even after you've exited out of them.
Is there a way to "lock" some apps into a memory so they never quit by the android OS except if I would decide to?

You have a valid point, but most of the time those apps don't do anything critical that it would hurt to interrupt. I usually prefer to exit them normally, but sometimes I just kill it, like when I forgot the Messages / Internet open. No need to paranoia though, leaving a few open won't kill your battery.

That's exactly what I needed. There are some apps, like SetCPU, TB, Root Explorer, which can be added to SuperUser authorization and it won't get killed by anything unless someone manually kills it. I'd really really like to know how to add an app under SuperUser or anything which will do the job to add the app in to the OS and which can't be killed by any Task Killer or anything.
Besides I also hate those Task Killer apps, they are meaningless unless an user do nothing regularly with his/her phone.
I've no Task Killer installed but once I used the built in Memory Clear feature and next day my schedule app got closed. From then I never touched it. But one thing if RAM usage goes above 400 MB I think sometime its good to clear the memory as it will help to refresh it. But Samsung should had put the Memory Clear feature more precisely.
Regards.
