Now when installed a lot of apps including juicedefender and advanced task killer (set to aggressive when screen off with lots of exclusions) the lag has become more of an issue.
Now tell me whats the logic behind having installed a lot of apps and a lag? Running several apps multitasked will offcource produce performance-dips but just having them installed?
What exactly is "aggressive" on the task killer anyway? Some people say its just bad to kill tasks.
I have the idea that its the widgets that causes trouble, since they actually needs to run in the background all the time. I noticed today that the fancy-widget got stuck on upboot for like 60 seconds, that caused the 4 buttons below to not load properly. Alto the rather useless "daily brefing" seems to slow down.
I dont want to root and hack with sd-hacks now when froyo is confirmed to be released officially soon.
Do you have experice with sertain apps/widgets causing lag. If so, it would be great to make a list of "bad" apps.
PS, I tested the 30-day navigon today in car and it worked with no problems at all. Fix in 2 seconds and right on track.

I haven't used it in a while, but "spare parts" in the marketplace tells you which apps are consuming your processor IIRC. This will obviously give you a temporary hit to your ability to load and run processes but will let you know more details about your phone that you don't already have and the battery use section of settings obviously only talks about what is using your battery but that isn't going to tell you the whole picture.
I am also someone who says you shouldn't use ATK, at least the way you do, but I have it installed and use it a bit differently. What I try to do is kill all tasks after I've used the marketplace or before I do anything intensive (gaming, GPS tracking) and I kill all apps including ATK. ATK will consume processor, battery and will free up memory which then Android uses to open more tasks you don't need (using processor and battery in the process -> repeat cycle). If you need to free up memory 1-5 times a day I think my way will save maybe 15-30% of your battery over a 24 hour period while costing you less than a minute of hassle (too much for some, sure). Again, I only kill after marketplace (because everything opens to check for updates, AFAIK) and before something that will use heavy memory and processor.

Forgot the first part of your question, forgive me. I believe, the reason for more apps causing more lag is at least 2 fold. There are more apps that can be opened when you have free memory (in the vicious cycle I described above). There is also something that might be a bit unique to our phone, and I've only recently read this, it's a bit of speculation so I'm not trying to pass it off as fact but I think it's likely to be knowledgeable on the issue, even if not completely correct. Samsung's internal storage method is an SD card, that allows extra apps to be written to the internal storage but comes with a trade off of lag due to a potential combination of:
slow random-access
bad partition
I think I'm missing an important reason, I'll try to look and edit.
When I initially got my SGS I loaded it with a heap of apps and suddenly noticed the lag and quick battery drain. Problem was I couldn't track down the culprit.
I recently reset my device and was a bit more organized with what I installed. One of the things I started doing was checking what services were being used in the process which you can find under the manage apps part of the system.
So while you can load apps and they may/may not be killed by android or a task killer, the services will always be running - taking up memory, sometimes cpu, network. Things like weather checking, news checking, even email sync are some examples. These services plus any apps you run are I think what starts the lag. You need to be aware of which apps are also run as services.
Yes, there are some bad apps (last Facebook version was found to be a heavy drain) but I think they tend to add up with all the other services running.
As for 'Aggressive' depends on the app killer but my understanding (with the one I use), is that there is a memory limit before the app is killed. Once the limit is reached on aggressive, it doesn't take much before memory is cleared.
One thing to install is SeePU as this gives an indication of CPU, memory and network on the top menu bar. This also helps when the system lags (usually CPU is high and memory is low) and helps to know when to clean (or what threshold to set).
Hope this helps.
Many people say it's harmful using app killers, especially on android as it may interfere with important system resources or close important system files and can do harmful damage in the longrun such as errors, things not working, etc...
When you open various programs such as file manager, picture gallery, etc you then see a list of all running programs in system/task manager.
Many of these running programs are ones you have recently used and are draining ram/cpu/battery.
Is there not ANY safe app to use that will ONLY close apps that YOU have used?
There must be some app out there that closes/kills open apps, not system or phone apps but only the ones you have installed and used?
This could be a ram killer or maybe a simple app which is not dangerous and will safely close running apps not needed.
Looking forwards to seeing what others recommend.
Thanks in advance guys,,,

Names please of a good app that kills ONLY programs you open, not system files.
What if I was to install an appkiller, but instead of having it on autokill, I was to manually click apps I opened and kill them?
Surely this way there is no danger as I'm only closing selected apps, not system files?

The point is, even after killing your own apps, most of the time froyo will restart them
I very much like ES' offerings - ES File Explorer and ES Task Manager. They're both free, give em a birl.
You can install Advanced Task Killer (free) and there you can perfectly select which apps to close and which not... still I rarely use it
for example your homescreen widgets are always unchecked when killing tasks, so unless you check them, they won't be killed...
Hmmm, ok.
What is the BEST way to preserve & save battery/cpu & free up as much ram as possible without harming/interfering with the phone??
When I used to use the task killer app it would consistently give me around 400-424mb free ram.
Without the app killer I would only have around 100mb of free ram since all the programs are running in the backround.
So to all you experts out there, what can I do or what options do I have in which I can safely free up as much ram as possible and safely close running apps not needed when not using the phone?
I just want the best and most effective way to make my battery last longer.
I'm having to charge my phone every day, it struggles to get through the day even when hardly used.
Looking forwards to hearing some expert opinions based on the above.

There's definitely a problem there but you're not going to find it chasing free ram. I have approx 20Mb free ram at the moment, the phone hasn't been rebooted for at least a week but I'm easily getting through 2 days with light use. Task killers / app killers are not the answer, (in froyo at least) free ram is wasted ram.
The programs that are 'running' in the background are not actually using CPU resources unless they have a service running (see the eBay app/service for an example). Your best bet is to check the running services (settings/applications/running services) and battery usage to work out what process is hogging the CPU time. Also check your sync settings, though I'd imagine you've already tried that.

Maybe it's the anipet fish aquarium live screensaver...
Systempanel is good, I use it to stop a bad app thats using to much memory..you should never kill your apps with froyo, the OS wasn't designed like that, thats the whole point of Android, it looks after the apps perfectly well by itself, systempanel is just there as a....just in case method.
Saving battery power is a common misconception, Task killers actually get in the way of Android handling memory management as intended.....a pointless app to have with 2.2 which actually drains you battery quicker.
The LCD screen is the biggest drain on battery power, turning the brightness down, stop using a live wallpaper, turn off wifi, bluetooth, GPS ect....
With all that said the 1250mah battery is just not powerful enough to run this device period...but then most of us knew this before we bought the phone..we needed a 2000mah battery really, its just a lipo battery and can be easily increased, maybe next year we will see an improvement in the new smartphones.

There are many apps that keep loading, not only after a Reboot, but even when I use System Monitor to stop all programs, then when I open an app and check System Monitor again, a bunch of apps have relaunched!
This is really annoying, especially when memory is at a premium on the Archos 70 ....
Honestly, I think that is just an Android thing. No idea how to help you except to say it did that on my G1, my Evo, my Epic, my wife's Intercept, the Nook I had on loan, and my Archos 101...
You just have to roll with it I guess...

android will clear these apps from memory when needed
you should only worry if these background apps use CPU (and battery) all the time
Something I posted to another forum.
Android uses a method to kill background apps automatically when space is needed in RAM. So effectively it cleans up after itself.
Here is a fairly good explanation of how the system is designed.

Try "autorun" from the market. It can stop some 3rd party apps from starting. No root required.

Most taskkillers started their life a year (and several Android versions) ago. Back then, Android's memory management was less mature and phone memory was smaller. The improvements that came with Froyo make them obsolete and even troublesome.
When Froyo senses low memory, it will kill stuff. Otherwise, it leaves stuff in memory, operating with the thinking that "unused memory is wasted memory". As new apps open, it kills off older- open apps.
The problem with taskkillers is when the user sets them to automatically start killing stuff. Some apps have the rude behavior of self-restarting. In this case, when the taskkiller kills an app, the app will restart itself, putting it back in memory. Suddenly you have tug-of-war game between the taskkiller & the app. This increases cpu usage and kills your battery faster.
Killing things with the System monitor is alright, because it is a single time action by you. If an app restarts, that is it. There is no ongoing battle.
I do use the Autorun Manager app. It lets you pick apps you want to keep from starting at boot. The nice thing, it tells you if they are self-restarters, if they are there is no need to check them. It is useful to kill the nonrestarters (like the XDA app) that don't really need to be in memory when you first start.
I hope that helps.

I stopped killing apps, and now my Archos 70 is running much smoother! I watched a video about someone using their Archos, claiming that the apps need to be loaded, in order to keep things cached, which helps the Archos apps run smoother, with fewer glitches.
My Archos runs less choppy now, but still a few glitches here and there.
I'm still very pleased with this 7-inch tablet! Took it out for a test run while riding my Surly Long Haul Trucker around town yesterday -- listening to my music in PowerAmp.
Hi all,
I've had this phone for a few days now and love it. However I find I have very little RAM available.
I have on average around 30-40mb of ram available and the phone sometimes slows down quite a bit. I've ad a look at the running apps and the main culprit was SPB Shell launcher which was using around 50mb. I have since stopped using this but I am still only getting around 40-50mb remaining (with timescape disabled) and again a sluggish phone at times.
How is everyone else's?
I am thinking of doing a factory reset and start afresh to see what app may be causing the problem.
Any other suggestions or is this normal with this phone?
Thanks for your replies.
I have the same. I thought it was down to having over a thousand contacts all duplicated in exchange and google.
I have 130m of internal space available. Is there any way of re assigning it as you can in windows mobile?

My Average Free ram @150 MB
135 - 140ΜΒ here.
Have been checking with Advanced Task Killer (ofcourse NOT automatically set to kill everything, but fully manually every now and then), and noticed that there were times when the phone just left plenty of unnecessary apps wondering around in the background. Apps that are not the "always-on" by android system. So I kill EVERYTHING else except from:
1) Clock
2) TrackID
3) LiveWare
4) Media Sharing
5) Maps
6) Hanashi (WTF is that?!? it ALWAYS comes back by system.)
7) Setup wizard
(What remains always active by system also depends on the widgets you have, e.g. I have TrackID widget, you might not have it, so you wont need it.)
and have even noticed better battery performance...
EG, during nightime, I left the phone untouched (not used ATK), and when I woke up, I had a 12-13% battery drop, while the other day, after a fresh cleaning before sleeping, got around 4-5% drop. Both times with same conditions...
I have about 140 free and nerver under 100

Yeah I have about 150mb free.
And can I say coming from the x10, this phone is rediculously smooth. I love it!
Can we expect more free RAM once it's rooted/a custom fw is available?
This obsession about RAM needs to stop!!!!! 2.3 manages memory very well and you shouldn't be having any issues with the phone, unless you start messing with it (task killing the wrong things for example).. My phone is running really smoothly.

The reason I asked is that my phone does not run smoothly at times but very laggy and some items (contacts, emails etc) can take an age to load (well not an age but seconds but it feels like an age )
I was just wondering if this was the norm or not.

Yeap, 2.3 handles RAM almos perfectly. EG, if you open as many apps as you want and just leave them in the background, when you try to launch a HUGE game (eg Asphalt 6), the system will free as much RAM as required for the game to run smoothly.
BUT, I have noticed that some apps are left idle without me usng them (and without being system triggered apps, which when closed, are not resprang), and are not automatically closed by system. I tested leaving overnight the phone without killing anything after a days usage (with more than 15 apps in the background), and while being at 15% when left at night (around 01:00 am), it was off in the morning (7:30 am).
Then I did a fresh reset to the device, noticed what apps are automatically opened by system, and protected them (unchecked them) from Advanced Task Killer (which was set to manual), so that it will not shut them down when I click the "kill all" button. Next night, I killed all non-system apps (that do not restart if you do no action), and left the phone overnight again to see if there is any difference. Battery dropped around 5%.
I did this twice under same conditions (same time gap, BT open etc.), and results were almost the same +/- 2%.
So IMHO, if you use a task killer app wisely, you could manage to get better battery performance when the phone is idle, but you will NOT get better performance (smoother UI etc.)
Again, all these IMHO.
@dragunov - completely agree with everything you're saying.. it's the difference between knowing what you're doing and blindly killing tasks because someone said it helps!!!
for the OP - would suggest figuring out what it is you've got running that's causing the lag cos it's not the phone hardware/ OS that's at fault - This is the only drawback of Android vs iPhone -the QA of the apps on the market doesn't pick up this sort of problem.

Thanks, thats what I intend to do. A factory reset and the re-install gradually my apps to see which ones are the problems.
When I first got the phone I loaded it up with apps so it will now be difficult to retrace so a fresh start is what I will do.
A quick update. I have done a factory reset and although the phone is smoother I still only have 40-50mb free (only app I installed was swype).
Can I just ask what free ram other users have?
Thanks
Right now.. 60Mb.
I had about 150 out of the box while taskkiller always said about 5 apps running background (not installed by me).
Now yesterday my arc froze while browsing the web and rebootet itself (screen was scary, single pixles loosing light while some were still on till everything was off).
Now that was the only time the arc did that and afterwards task killer now (after killing apps) only shows 2 or 3 apps running background and up to 195MB free RAM which is cool but scary at the same time ...
Still can recieve phone calls though and everything works ... well Im happy for more RAM
Oh yeah, got swype on my whitelist.
Honestly I don't understand the need for more ram?
having 60mb is similar to having 200mb, it's all about applications reserving their spots, once they needed they'll kick in, otherwise they stay idle ( talking about system apps and well developed applications )
even if you have 60mb you still can run games that require 100mb... smoothly
the lag some face is due to background application using the processor
I usese autokiller memory optimizer. See unlike the other appear that kill everything, autokiller mo just optimizes the Android system so you wont have to go hunting for those apps.

Doesn't matter how many times we say it people just won't get it!!..
Spare memory is WASTED memory.. this is ANDROID/ Linux.. this is NOT MS Windows... it's DIFFERENT!!
New owner of a Nexus 7 2013 here. Had it for a month or so now.
So the device came shipped with 4.3, I updated the device to 4.4.2 OTA. Weird thing is, everytime I "Force Close" an app from Settings, the RAM usage decreases, then it INCREASES!
Google Play Store (44mb), current RAM usage: 444mb
Force close Play Store, current RAM Usage: 400mb
*a couple of seconds later after display refresh*
current RAM Usage:480mb
This keeps going. No matter how many apps I force close, the RAM usage keeps increasing until the point where it reaches ~660-~700mb!
Is this normal? Does this happen to anybody else? Is there something wrong with the garbage collector? Also my RAM usage is in the 400mb range on startup and a LOT of apps run on startup which I need to force close manually (is it normal they run on startup?).
Thanks!
So memory usage is supposed to increase when you force close apps, so I take it this is usual for Android? But is there any explanation as to why ram usage increases instead of decreasing like on iOS? Is the garbage collection on this thing significantly different to conventional Linux kernels or for that matter Windows' variant too?
Sounds like a very stupid idea tbh

OK wrong forum this one is for the n7 2012 but your question is more to do with how android runs rather than specifically the nexus.
First of all forget everything you think you know about ram. In android the more ram being used the better the device will run. This is not always true but largely the more apps being held in ram the smoother android will run them. When an app closes it moves from running services to cached and the system will then call on that if you reopen the app or clear space if it needs it thus saving itself valuable power. The other reason for not force closing apps it they no longer run in the background as they were designed to. This is one reason task killers are bad for your system. If you close the mail app you won't get emails, if you close the clock your alarm won't go off, if you close the play store your apps won't update ect. Android is as far removed from windows as iOS is although windows 7 does use a similar idea towards ram. It doest need you to clear ram its perfectly capable of doing it itself. The exception to this is when you get badly designed apps that don't clear up after themselves and stay in the running services.
Try looking in your cached services you will probably find that's where your ram increase is. By force closing apps you make more work for the system reopening them.
