[Q] Could someone clarify?

Okay, so I hear in FroYo that you're not suppose to kill and end tasks? Does that means services as well? And if I wasn't suppose to kill them, then wouldn't that make my battery life worse because of all the things running in the background?
TIA

You shouldn't use a task killer in any version of android from Froyo on, froyo handles its memory management extremely well when left alone, using a task killer could result in apps constantly opening and closing in the back ground, which would use a lot of battery .

Alright. I got rid of my task killers. Is ending services fine though? And what about the task manager that the phone provides? (I'm guessing the second one is a no?)
And what other precautions should I take for battery (other than having low brightness, of course)

Only use the one built into the touchwiz framework if you have an app running out of control hogging resources.
If you're looking to improve battery, I strongly suggest Juicedefender with ultimatejuice, I have almost tripled my battery since I started using them.

I use the Advanced Task Killer for Froyo. Several apps I have like the Weather Channel and stock browser lower my available memory to a minute amount of what it was at boot up and do not reload if killed.

The amount of memory available on your phone is supposed to become low. Apps are stored in memory when not being used. This does not take battery and allows the program to start in a faster fashion then otherwise.

I'm sorry guys, but the information given in response here is really dangerous. Yes Froyo, and all versions of Android have built in memory management. HOWEVER, it is the job of the application developer to use the proper calls and closes to make sure the application isn't holding onto resources when in a background state. This is NOT always the case, and is constantly overlooked on all OS platforms, especially with how fast application development is happening on mobile platforms.
YMMV, when and if you should be using task killers.

No it's not. There is only 337MB of RAM available of which about 150 is used by system. If I keep loading apps that stay in memory when not being used I will have no resources or memory available for additional web pages or other apps. Why should the Weather Channel app load 50 MB of memory and stay there if I use it twice a week? When an app is closed I want it out of RAM. I can wait the 50 milliseconds to reload if I want to use it again.

Here we go again another argument of task manager for android
For me i use advanced task manager to kill some apps to speed up my phone a little and also use it to switch between programs that are already open where as if you try reopening some programs the restart,
I also ignore apps that i need to open and stay open like beuatiful widgets, word games to get more reliable notifications and widget locker.
I freeze with titanium some services such as drm and sns...

Free RAM is wasted RAM. Unless your trying to track down rogue processes, task killers are totally unnecessary.

What that article hints at but doesn't exactly explain is that due to how the Dalvik JIT works, killing those apps that aren't actively consuming CPU will cause worse performance over the long run. The JIT has to spin up everytime the app is loaded - if it is already in memory then it's already optomized.
At least that's my understanding! I could be totally talking out my arse
EDIT:
Here is its straight from the Dalvik lead dev.

Well don't know about performance but yesterday killing apps with ATK Froyo especially the browser, I came home with 62% battery left. Today had about the same use but disabled ATK and never used it and came home with 31% battery left. ATK is doing something for my battery and will give up apps loading quickly for battery life any day.

[Q] Memory management

Hi Arc Users,
Do you guys encounter low memory after long period of usage? It seems like the memory does not free up after using the phone for a long time. I mainly use the phone for FB, Camera and messaging.
When the phone hits like 50+MB ram or so it starts to slow down and if it goes lower than 40MB my home screen starts to lag and the app icons take a few secs to load every time i return to home screen. I'll usually reboot the phone but its quite a pain considering the boot timing for my phone is rather long, like close to 1 min.
What are the possible solutions? I've heard that advanced task killers are unnecessary for Gingerbread. If thats the case, how do I free up more memory or have better memory management for the Arc?
Am a first time android user, appreciate any advice from you guys
Thanks!

Root is the solution. Delete apps and services which you do not use.
I haven't any problem either when free ram goes down to 30MB and i don't use a taskiller.

Just what are you doing when you run out of ram? Never did I run out of ram yet. Running ram hungry games will free up more what is needed as I experienced. When I return to homescreen, it takes a while (around 2 secs) because it will free up ram from the game, then load the homescreen launcher from start/scratch.

Same here but my Arc works fine, even with 30-40MB RAM, so it isn't a real problem.
But it would be nice from SE to make 400-450MB of the 512MB RAM available for the user.

What? That is a completely pointless excercise if you understand how ram is handled by the os.
You need to root and remove bloat, check ya settings etc to get better performance. I found letting things constantly access the network was a juice eater, I don't want fb to check every 4 seconds, I update it when I want to read it lol
I use a task manager, but only because I like to see what is running and using resources. I rarely actually kill any apps, just occasionally a few things I rarely use. Even then it fills the space with other stuff.
:edit: sorry flo95, that sounded a bit crappy, no bad attitude was intended.

not a task killer... a memory manager that enhances googles memory management.

I do not play games with my Arc. I just used facebook, MSN, Camera and messaging occasionally throughout the day. Medium usage.
It runs smoothly for several days but maybe after a week or two, the RAM starts to get low.

I use battery guard as a task killer. It comes with a widget where you can see the available amount of ram.
I'm happy about it. Though a lot of people say a task killer doesn't help I have no negative experience using this one... and I never go below 130 ram.
I still think it does help to close tasks that otherwise keep running in the background... But I'm new on android so I could be wrong.

Hey guys
Have you tried this script
http://forum.xda-developers.com/showthread.php?t=1111145
maybe this can help w/o having to install apps or task-killers. Should work on Xperia Arc but I don't guarantee it.

That script seems to do basically the same thing as auto memory manager.. (per my previous post..)..
PS.. I currently have mine set to aggressive.

RAM usage after eating ICS

honestly, its become smoother and much responsive than in gingerbread
but the available RAM has also noticeably reduced, in fact, a LOT!
in 2.3, it was somewhere between 300-350M after average use (not boot up)
now, in 4.0, it can reach as low as 180M, usually 230M i think
please advise if sort of memory freeing app is necessary
thanks a lot

I advice against task killers. You could install the init.d support and run some scripts to help optimize your resources.

Sony did said ics took more ram than GB long time ago. You dont need to freeze any app, the system will automatically free up unused app ram once it requires more ram from current app

thank u all comments have been helpful

Of course more ram is needed for smoother transitions and so on, once you notice the phone lagging and having most of its ram used then its a problem. GB is smooth for me right now knock on wood
Sent from my LT28at using xda premium

i've been on ICS for 5 days and checked pretty regularly. Only rebooted the phone once since i flashed it. This morning i have 360Mb in use...GB i seemed to always hover around 300Mb in use. So so far the ICS hit doesn't seem too large on my end.
There are about 20 odd apps i haven't reinstalled though since the flash; mostly games and a few things i ended up using less than i thought i would. I have 3 home screens stuffed full of widgets for data toggles, weather, music, etc. The main home screen being relatively empty, and the other just straight up app icons.
It swings a lot though. the ICS browser, with lots of windows running, will eat it all up...causing it to take a second or two for everything to pop up on the home screens when i quit out. This is my first android device, so i'm still learning the ins and outs...but i disabled every AT&T app i could, and they are no longer showing up in my process tree...Navigator used to eat 40Mb of memory despite me never once opening it..that'll do until i get around to digging deeper and removing them entirely.

4 bucks for a 87KB app? xD
Lowest ram I had was 51MB, and I use Sense 4.1. I would say using task killers help if your one of them people who want to see your ram high. If your device feels sluggish after use, use a task killer, or reboot.
I'm sure CM has that low mem problem though ither way. I saw someone posting bugs about it.

i said it numerous times... android is NOT windows. your free ram in linux => your system fails to work. your free ram in windows => you can open up more programs until the ram is full.
in linux it is better to have the whole ram full, not free. if you want more infos, you can search on the net.
When an Android app is no longer in use, the system will automatically suspend it in memory - while the app is still technically "open," suspended apps consume no resources (e.g. battery power or processing power) and sit idly in the background until needed again. This has the dual benefit of increasing the general responsiveness of Android devices, since apps don't need to be closed and reopened from scratch each time, but also ensuring background apps don't waste power needlessly

Android manages the apps stored in memory automatically: when memory is low, the system will begin killing apps and processes that have been inactive for a while, in reverse order since they were last used (i.e. oldest first). This process is designed to be invisible to the user, such that users do not need to manage memory or the killing of apps themselves.[65] However, confusion over Android memory management has resulted in third-party task killers becoming popular on the Google Play store; these third-party task killers are generally regarded as doing more harm than good.

Low memory!

How much FREE memory do you guys have when in normal usage (with browser, Facebook, whatsapp, tapatalk open..)??
Here I usually get 200 free, so I constantly have to free memory (it goes from 200 to 450, but few minutes later, it will be the same thing).
Help, anyone??

I usually have 1.1 gb free with kakao, whatsapp and basic apps running in the background. I close Facebook as I leave it, Facebook is a big memory hog.

I have about 900-1.1 gb used

Look at what is running. It sound like something is running in the background that is sucking up the memory. If you do a reset and re-install of everything, before you find out what is causing the memory problem you may be right back to square one.

I agree with this, when your talking free "ram" as shown in the task manager , it is what is running at the time, not what is installed?
In my system i have not seen the "ram" ammount drop below about 350m ever.

Usually ranging between 200-400 free. Usually if I close the browser and clear my task manager, I can get higher. The thing is, why would you want all that unused? If your battery isn't being drained and your phone isn't lagging, you should be good to go.

Hmm!!!!!
only 200 MB free??
I have 500-700 free everytime!!
well, even if it is only 10 MB free, you should not worry about it(its a smartphone), until it affects performance of battery life!
to check whats eating up your RAM, go to settings>>general tab>>apps>>running tab!
you can also go to battery settings to check the most power hungry apps!
or you can install DU Battery Saver!

PsykoGeek ram or memory is what I was talking about but that also includes the apps or software that is installed on the phone also If the underline problem is not found first, anyone can do a factory reset and re-install the app and there is a very high percentage that it will come back.
I would look at the app that I have downloaded and start to turn them off one by one and see which one could be the culprit. After you found one or two, see if you can live with out them.

High RAM usage is actually a good thing on Android unless you use a lot of emulators like I do. On PC, low RAM is good, but on here the more RAM that's used the better it is. Makes opening apps much faster. What would be killing the battery is an app keeping your device awake even when the screen is off.
