I suspect there is a memory leak somewhere in the Sense UI or or in Android. When I boot my phone and kill all the apps I don't want running, I see 96MB of free ram. But after a day, with the same apps running, I am down to 46MB. This has the result (or so I assume) of making my phone feel more sluggish even though I'm running the same apps. Rebooting fixes all the sluggishness, and the Hero flies. Is anyone seeing the same thing?
I've been using it since launch and haven't had much lag.
You can always try a hard reset if its that bad.
Test it while using regular home and kill sense UI, see if there's a difference.
Well, I only get a lag from time to time. It's just that I noticed this increase in memory usage for no particular reason. I'll try to track down the offending apps if I can. I might try a hard reset though. Can't hurt.
I notice that the browser and my exchange "mail" process freeing up the most memory when I use Advanced Task Killer to "Auto-End" all non-excluded apps every hour.
Once, the mail app was taking up 30mb of RAM. It's not uncommon for the browser to take up 20 or more either. After a while, I also see what you mean, in that when I first start my phone with the same 6-9 system processes I have anywhere from 90-100MB free, and after a while when killing them, I can only get to 75-80 free.
Since I had the Mogul a while back, I tend to watch RAM closely since that phone only had a measly 20 free after boot.
Same Here
I'm seeing the same thing as well. I use TaskPanel X to track memory usage and apps. Likewise the memory seems to slowly decline over time. Additionally even if I kill all the non-critical apps so it is like it was when it booted, I'm still about 30-40MB less than after a fresh boot.

It is because different task killer have different security policy, which allow them to show the system apps or not. So, in the lower security policy, you can see more running apps and gain more memory after kill them
i do have a question. why are you using a task killer?
I'm not having a dig at people that use them, but more trying to educate people that they are not required
"free memory" is not indicative of a healthy system in linux based machines.
please remember the way in which linux based OS's (which Android is) handles memory. Basically, if you have a heap of free memory it is simply wasted, the OS is not running any more efficiently. It is actually slower.
Here is a quick overview. Written for the desktop computer perspective, but translates over to a mobile phone OS quite well.
"Traditional Unix tools like 'top' often report a surprisingly small amount of free memory after a system has been running for a while. For instance, after about 3 hours of uptime, the machine I'm writing this on reports under 60 MB of free memory, even though I have 512 MB of RAM on the system. Where does it all go?
The biggest place it's being used is in the disk cache, which is currently over 290 MB. This is reported by top as "cached". Cached memory is essentially free, in that it can be replaced quickly if a running (or newly starting) program needs the memory.
The reason Linux uses so much memory for disk cache is because the RAM is wasted if it isn't used. Keeping the cache means that if something needs the same data again, there's a good chance it will still be in the cache in memory. Fetching the information from there is around 1,000 times quicker than getting it from the hard disk. If it's not found in the cache, the hard disk needs to be read anyway, but in that case nothing has been lost in time."

yes and yes!
if your phone requires the resources, it will kill tasks that are no longer required. its all automatic. let it do it itself and you will have a much happier phone
AND better battery life, because the android OS is not continually restarting processes that your task killer deems unnecessary. I would trust the actual OS over a 3rd party app. It is designed that way for a reason (see my previous post).

The idea is absolutely right if memory is being used for apps you are likely to open frequently. ATK allows you to unselect the apps you want to keep running. That way you can unselect the ones you use the most and then use the widget to kill everything else.
I notice when I press the home screen many apps don't kill them selfs and after a while I have loads of apps running and the system starts to lag, specially when I try to run something else.
There are advantages in both approaches and I find a mixed combination (available with ATK) makes it best, although the user need to use some common sense to do it right. Killing everything means the system will be more responsive but regularly used apps will take longer to start up. Not killing means the apps you use a lot "startup" faster when you use them repeatedly (as in fact they never stop running) but after a bit the system will lag when using other apps and may need to use pagefile/swap to atone for the lack of free RAM. That causes page faults which make the system even slower.
The iphone developers aren't complete idiots for killing every app. They have a priority for system responsiveness and they did achieve it at the cost of background running apps. I like the possibility to choose what I want to keep running and kill the apps I'm not likely to use again and it's one of the reasons I picked android.
A little Offtopic to both ifanboys and ihaters:
I never owned any apple product as I think of them as over priced. That said I think the iphone has great merit and I doubt very much we would have Android if the iphone didn't pave the way. Besides I jailbreak my brother's 3G and made it multitask enabled. Now it runs apps in background and there is little diference between it and my android. Except for the extra 200€ it cost, the lower hardware specs and expensive service provider contract my brother pays for a mandatory 24 months, while my X10 cost ~65% initially and came free of any contract.

Thats what I and others have found, which is why some people choose to use one, myself included. Someone posted a link to an article last week with similar information posted here about the OS handling itself, but the comments section of the article were full of comments similar to what pco and myself have said, so it's all down to personal preference whether or not you choose to use one.
I did use a task killer for a while, then stopped. Personally my phone is better without. I have nothing except weather that updates automatically, I do it manually when I need it.
It is one of those things, just like on a laptop, everyone has different configurations and usage patterns that results will vary.

Don't apps exit when you keep hitting the back button? And for games doesn't hitting exit shut down the app?
I thought its a feature that apps don't close when you hit the home button?

The browser for instance doesn't. Same with many other. I think it's up to each individual developer to program that behavior for his app.
I got Visual task switcher and I notice lots of apps just stay running forever.
Task killer caused probs for me. A daily switch off doesnt hurt, but have run mine for 7 days and been ok. Even a bberry cant do that!

Guys, don't use home button to exit apps.
Will just send them in background.
Use the back button... this won't exit (most of) the apps but will put them in a "sleep" state so, next time when you will use it, it will load faster.
So, again, home button will put the app in background, still running.
Test it with an audio player for ex.
Or a browser... send it in background with home button and the player will still play or the browser will still have that page loaded.
With back button, after all views are "closed" the app will close too (well, put in sleep state).
I use ATK only to kill the apps i use once in a while ... the rest of the stuff, is always in memory.
My X10 has usually about 25Mb free
Actually I used ATK to kill application that need to connect to internet, and in my case there is extra charge payment. But after i used ATK I don't notice that the battery live is longer. So I ever ask someone in my thread about after ATK kill applications and so forth....
And somebody told me to quit using ATK and now I realize that the battery last longer than before.
But one thing still bother me is:
Setting - Wireless control - mobile network - mms & data (no checklist)
means: I can not access internet and receive or send mms either.
Actually I only need MMS, not internet.
May be somebody can help me solve this problem.
Thanks.
But my conclusion:
NO NEED ADVANCE TASK KILLER.
After I uninstall ATK, my phone still running smooth and the battery last longer.
May be we just need best Cache cleaner. But I still trying some of that.
@pco.vaz
I don't want to be mean, but you are wrong.
Even those iOS versions that are not multitasking enabled keep apps in memory. Leaving an app on an iPhone resets its UI state and halts its processes, but parts of the app are left in the memory. You can see the difference in loading speed if you decide to reopen it.
There were apps that could show memory usage and clean it on the App Store, but Apple removed them. You can still get them through Cydia and see for yourself how memory management on iTouch devices actually works. Basically the iPhone goes as low as 3-4 megs of free memory and handles it in smiliar way as Android.
On both Android and iOS, apps that are in background are paused after a while and do not use processor cycles. Memory they keep occupying is overwritten if needed by another process.
I do not recommend using task killer to people who do not know what they are doing exactly. Killing even simple processes often causes phone instability and drains battery faster, as others have already said.
If you feel your phone is stalled, perform a simple reboot. There are apps that run in background (in most cases you are warned about this) or are poorly coded that could cause this behavior. Other than that, inbuilt application manager is able to force close apps pretty well, if you need to kill a single app causing problems
Hey
Till last week I used to have an average of 400-450mb RAM free on the phone. Now I have a max of 250-260mb free. All that I can remember doing different to the phone is installing a few games and other apps, which of course are not used 24/7.
I'm using Advanced Task Killer (free version) and I have set it on "Crazy" app killing every 30 mins. Still I'm stuck with around 200mb. I can feel the lag when scrolling through the homepages.
What did I do and more importantly what can I do?
did you try rebooting the phone..heheh
if you have CF-root .. boot into cwm..clear cache..clear dalvik cache and reboot..
You shouldn't have lag on the homescreen regardless of whether you have 200mb or 400mb of RAM left..
Are you using many widgets or a live wallpaper (or apps like 3g watchdog or anything that keeps a presence in the notification bar like SetCPU?), sounds like you have a memory hog somewhere
And forget using a task killer.. the apps will just start up again anyway which will waste more RAM, find AutoStarts from the market and stop useless junk starting up
Thanks guys for the quick response. I actually restarted for some other reason and found that the RAM was back upto 590-595mb, but thats probably just coz of system files not starting yet. Right now, say 30 min after restart its around 475mb.
I'm running the stock KE7 ROM, so I'll try clearing the cache in that and see what happens.
There is no point in having "free" ram on android. Uninstall ATK and just use your phone. The constant restarting of killed applications does more harm than good and might even cause your lag.
Hey...not sure if this has been answered before or not but im trying to figure out battery draining issues and one of things ive always used is ram optimizers...I have Android Booster and Android Assisant ....and then i also use the built in task manager to clear memory...shouldbi be using these apps or are they draining the battery by running in the background? They seem to clean up a nice amount of memory....and keep my phone running fast....just dont know much about them...

I do not think that by cleaning your RAM, you can reduce power consumption by RAM.
Actually, you do increase it. Android itself closes unnecessary applications when needed to clear memory. But, when you clean memory, either by task manager, or some custom tools, you are basically forcing applications to close and restart unnecessarily. I would say, it is additional load on CPU, and thus on battery.
For most applications, exactly startup and finish times are most expensive in terms of CPU load and battery. And most well-designed applications will not drain your battery when paused.
Reminds me of RAM cleaner programs for Windows machines, that would simply trigger excessive page faults.
while i agree with most of what you posted, there are 2 major flaws in your logic:
1. you talk about closing apps that restart on their own, but not many apps actually do that. sure, widgets, services, your launcher, communication apps and syncing apps need to run in the background, but certainly there are other apps eating away the battery, that need to be fully closed, when not needed. kies air or wifi file explorer come to mind. some of those apps don't fully close through the back button and must be killed from a task manager to save battery.
2. you say apps are paused. that is not necessarily true. many apps are capable of fully running in the background, after all, we are talking android and not iOS. we have full multitasking and apps are not generally suspended. say, you want to play a game for the first time and it needs to download more data. you can do whatever you want with your phone, open a dozen other apps, browse and listen to music, that download will continue in the background. this might fill up the ram over time, if you never close an app or apps do not allow direct closing.
there is a reason why samsung supplied the phone with a built-in task manager.
some apps are not well made and don't quit properly and need to be killed that way and killing off unnecessary apps (that won't restart) makes sense.
and let's not forget apps that get stuck but don't force close. they need to be killed as well. what else are you gonna do? restart the phone? certainly that wastes way more power than a restart of a few services.
every time you have a look at the samsung task manager or the "running" panel of "manage applications" and you use 500 something MB of ram and kill all apps, it will go down to something like 200 something, then the services restart and you are back up to maybe close to 300 (all numbers vary on your rom and apps). given that situation permanently saving 40% of ram is certainly a good reason to kill apps before you put the phone in your pocket.
I guess, then, it is best practice to kill all apps from task manager, a few times a day, especially after using several different applications and closing them. Applications that are needed will be restarted automatically.
I am not sure about running so called "RAM optimizers" constantly, though. When you are using your phone, it simply introduces more lags. Otherwise, it does nothing, if you have cleared RAM after heavy usage.

killing itself is not necessary in the 1st part.
the more the memory android uses the better the apps behave, thats how android is desinged.
if you people still want to release some memory just use the samsung task manager ot clear memory or "fast reboot" from market.
Thx for the posts...i deleted the 2 android apps for now to see if theres a difference...i will trybusing just the built in task manager for a few days and see how that goes. But for example i mainly use my phone for words with friends...facebook...twitter and instagram....when i run the built in task manager it frees up mabye 200mb of ram....then i would run android booster which would clean up another 200mb and would close stuff like facebook...and tweetcaster and so on....the built in task manager doesnt seem to pick up on and close everything it should...which is why i downloaded the others...my phone has 800+ mb available and i usually find that ots using 500 of those 800 at all times...i wouldbfind myself constantly closing stuff with the optimizers...but like you said...they just open up in the background again anyway. Im rooted and have got rid of all the safe stuff to get rid of and the funny thing is i still dont see much of a difference in ram consumption...i think of ram as important cause it keeps things running smooth with no lag...not sure what to do i guess...ill try it like this without the optimizers and see how things go and download them again if i get bad lag...what i really need is a actual list of my phones internal software so i can get rid of the rest of the unneeded system files...ive found similar lists..but never a list of my actual phone...theres certain stuff running on my phone that isnt in the lists ive found so i left them with the worry that i may have to reinstall the rom if i delete the wrong thing...im also a android noob...only 2 months of using it so far so ive got tons more learning to do...thx for the opinions tho...keep em coming if you got em!

But the DEAL KILLER for me is browsing. I mean, it is just nuts. I have a super fast wifi connection and I'm getting excellent signal but pages take FOREVER to load. I mean, like 10 seconds even for the most basic HTML page.
Why Android, why? What the hell did you do to HC that completely broke the browsing experience compared to GB and why didn't you ever fix it?

Yeah it's crazy. Ever since I flashed back to HC browsing takes for-e-ver to load.
Mine gets like that when i have to much apps open, download a task manager and kill the apps you not using, the more RAM you got free, the smoother it will be.
Gotta love it when folks post things as if every user is having the same problem when it's clear that's not the case. I think we discussed this before, but frankly if you have so much stuff active that you have to kill apps with a 3rd task killer to get your browser to work you have bigger issues.
The built-in memory management and task killer takes care of that very well unless you have badly misbehaving apps or other abnormal problems. If everything is normal in HC or even the older GB, there should always be approx 80% of RAM used. That's normal and if you kill things, android will just fill RAM to 80% again, over and over because that's how it's memory manager works and for good reasons.
And the browser in HC works just fine if you or bad apps don't screw the system up. Do makes sure you have some free space in flash for the browser cache and clear the cache occasionally.
Try rebooting your tab

Its true that there are always certain apps open, however if you open other apps and exit, they stay open. For instance my news app takes about 100 - 200 MB of ram when its open, if i exit, it stays open and occupies that amount, kill it. its EXTRA apps that you kill.
Just because you have a certain experience, doesn't mean it applies to everyone else.

I understand where you are coming from but the Theory behind DigitalMD's post is SPOT ON, the taskiller and builtin memory management within linux should not cause you any problems, also if a single app is taking up 100 - 200 mb of RAM there is something seriously wrong. What ROM are you using and if you can, please post a link to the ROM. I will try and help you out, i do not have a view but hopefully i can fix this
Not sure if it is wrong, just would like to get some explanation of this. Phone has bit less than 1GB ram available for apps and default behavior of Androuid should be to use it all for caching recently run proceses, because there is no difference if memory is free or taken - it uses same power.
I have Viper ROM 1.06 and using Nik3r kernel, tested with and without dataswap mod (128MB). Even tried to tweak Viper settings for minfree setting, using Multitasking ultimate profile. And still the same behavior. When I check available memory, it always sits around 750 used out of 980MB. Regardless what and how many apps I run.
Problem is, that when phone is not used for some time I see almost every time apps starting instead of fast switching from memory. Its mainly visible for me on FBReader, which I use to read ebooks every time I have little spare time. I pull phone from pocket, start FBReader and voila, it is starting from scratch loading book. Its 2-3s, but still. its relatively small app, shouldnt be killed most of the time thanks to system policies on free ram.
When I try to play with phone and run as many apps (start FBReader, home and run Chrome+load 2 tabs, run Camera, run Viber, run Tapatalk and back to FBReader) to force it to close my FBreader from memory, everything works fine and it swaps back in immediately. Even though checking Apps tab in settings shows memory usage about 750-800/980, not fully stuffed with cached apps (think its not showing correct numbers? Or not showing memory taken by apps in empty state?). But anyway. I give up, turn off my phone and let it be for some time. Then I check for example for SMS and would like to continue reading my book. And FBReader is loading as if it was closed. Why?
Seems to me like phone does cleaning of cached stuff in memory after some time when it is not used? Cant say precise when it happens, it just annoys me to see that system shows all the time around 750/980MB used and still is unable to keep my app in memory for longer period when it works fine if I test it directly.
Any ideas/tips/explanation?
