So I use 'Lookout' for virus protection. It's always running in the background from what I can tell via the notification bar and also as soon as I DL an app from the market place it scans it.
I was just curious how much memory it really uses and if it uses a lot of the battery up? It doesn't show up in the task manager hence why I posted this.

I have always been in the habit of streamlining everything (I.e. disabling all useless services in windows, etc.). Is there any information on which of the preinstalled apps I can remove? I'd feel safe getting rid of things like Google Talk and Amazon MP3 but am unsure what things such as "checkin service" do.
I removed about 6 apps from /system/app and noticed I could no longer download from the market. might do a little trial and error when I have more time.
Anyone have a source for this info?
From what I am able to gather, it appears Google Talk is needed for Market to work. No idea why, but it's needed.
See, google talk is always running in the background and I can't stand that. Would reducing the amount of apps in the "processes" tab in task manager improve battery life or increase internal memory? Just wish I had the time and resources to figure some of this out.

Yes & yes, sorta.
Obviously closing out background apps can improve performance, but noy by much. Android will automatically start killing background apps when it senses that it's low on memory. Biggest thing is when that "low" memory is. Your threshold is probably different than Androids.
So yes it does help, but not by much.
Oh, also, lots of apps are called up by system processes, so no matter how many times you kill them, they come back.
I was looking at an article about memory management on android. They say that android runs better without any manger. Correction it runs better without a memory manager. Question for you people, what programs do you use and what are your thoughts?

Most people use these app think it would enhance their performance.
I would certainly not object to such hypothesis.
However, I find that using these app would kill apps either too quickly or too late.
I do realize that there are advance options that would optimize such hassles. But after configuring these options, I found that it's easier to use my device without it.
So my final advise is not use it.

I think this is true in most cases. However who wants a 3D game running in the background eating up resources?
I recommend using a Task Killer but only killing heavy tasks like games, etc. I used to kill all tasks (which doesn't hurt anything really) but doesn't seem to be 100% necessary.
I also recommend that if you use a task killer (and want to kill all tasks) and a home clock widget (like beautiful widgets) that you add it to the ignore list or the time will eventually become off.
my captivate slows down within 5 mins of heavy use without me killing all tasks periodically with taskiller. thats why apple uses fake multitasking...u cant slow the iphone 4 down with applications in the background even if you try, because essentially there not running.......just paused and resumed.
It seems that one that is a good one to consider is one that tweaks the settings that the native task killer to android uses.
Here is an interesting thread on it. Out of that thread 3 of them have developed. I originally was using Advanced Task Killer, but after reading this thread, I am now using AutoKiller, and think it is doing a good job. And the end result of what to kill is decided by the OS, not the task killer.
The name of it is misleading, ad it does not kill tasks. It just changes the settings that the OS uses to make that decision.
I use ATK. I have security set to high (doesn't show processes), I don't use auto kill, and I have established an ignore list. I find that my device is faster with the way I use the TK.

So I have heard that using a task killer app could do more harm then good. Is this true? If not, whats a highly recommend task killer app?
Why you shouldn't use them.

I read this article via a link from gizmodo and it was very informative. I was using ATK for some time and thought it was doing well. I had no idea that many of the issues I was running into were actually coming from the task killer nixing items I needed running. I realized this after I removed the task killer and installed watchdog.
I am not going to say watchdog was streamlining power house for my phone but, it did allow me to see what was really going on in a much more efficient manner. The information it provides is useful and gives a much better idea of what is consuming all those battery eating clock cycles. I feel more comfortable now knowing what is actually active and whether I need it to be.
Since the change over I have been consuming more battery power but I just changed to Cognition and I have significantly less FCs. This is on top of my recent full time GPS usage and frequent music streaming.
I have been looking at a few apps in the market and I'm seeing more and more suggestions that the apps are a battery drain. How are these users so sure that one particular app is killing the battery? I can't find any way to see that, only the usage setting that shows display, phone idle, wifi and stuff like that.
Are live wallpapers really a battery hog when the device is not in use (display off and no other apps running)?
I'm using Tasker and have several (ok...17) tasker widgets that manage many settings and apps. I also have a few dozen profiles that manipulate tasks that are associated with those widgets. Any consensus that Tasker is a culprit? I do use it for alot of stuff.

I'm assuming that by 'usage settings' you mean -> settings, about phone, battery usage
If so, that should give you more of a breakdown than just what you had listed there...

I think you can use task manager to see what's running. It's a lot of experimentation . I'm testing itnow and it seems ok . I did a clean install of the sense Rom..( I prefer this UI) I installed no utilities no task killer no Setcpu nothing. I did not install Google voice disabled Google talk. Left background data but unchecked autosync. I put the HTC sync widget on desktop so I can hit it ever so often when I got the itch. Keeping gps WiFi bt off till needed will report back
Searched the market and found 191 task managers. Which dev are you referring to?

I am wondering if we have a task manager/process explorer app for Nexus 4? Currently I am using AirDroid v2 that includes a task manager, but I am looking for one with more options.
I travel a lot & would like to kill as much unwanted applications running in the background as possible to conserve battery.
There is no more need to use task killer to manage android systems any more. You will be doing more harm than good, in fact there is no good in killing tssks manually.

Point noted.
But when I use Airdroid task manager, I see a process when the corresponding app is not running the background.
To mention a few; Cut the rope free, stocks & Hill climb racing.
Few system process like picasa uploader, chrome etc.
As you said andoird may optimize most of them, but I would like some control when running thin on battery.

use greenify https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=en to hibernate any persisting apps/processes (except system). apps relaunch when you open them.
Killing apps and then having to reload them actually uses more battery than them being dormant in the background and already loaded when called upon. The problem is when you have misbehaving apps that stay in the foreground eating up cpu, instead of going dormant into the background. And this does happen. I use an app called Watchdog that alerts me when this happens. It allows you to kill the app when this happens. It also allows you to whitelist and blacklist apps and processes.

main phone setting, apps, running.. default task/process manager. in the top right will be an option to show cached process as well.

We all know that is there. The op mentioned wanting more options, mainly monitoring and kill options.

fast reboot(free), but the paid version i like better https://play.google.com/store/apps/details?id=com.greatbytes.fastreboot&hl=en
rayiskon, I will try greenify & let you know how that helps.
fernandezhjr, I agree restarting app is not an optimal way, but I require to squeeze battery to atleast make phone calls when I am away from charging options.
simms22, fast reboot looks promising. I'll try the free one for now and take it from there.
It's kind of already been said, but I want to clarify as much as possible.
Apps running dormant in the background (using RAM) use no more power than if it weren't running. This is because all of the memory you have is being refreshed all the time, the controller has no idea whether there is actually data there, it still refreshes the entire space of memory.
Apps running "dormant" but using CPU do use more power than if it weren't running. I assume OP is wanting some sort of monitoring app that shows which apps are using CPU, in which case is fine. If OP is wanting to kill all apps that he isn't using at the time to conserve battery, then he would actually be doing the opposite of what he wants, as it requires to CPU to spin back up to restart it later. Again, the difference here is RAM vs CPU, one doesn't use battery (or rather, uses the same amount of battery, no matter how much of it is being utilized), and one can use more or less battery depending on how much it's used.

Thanks for the detailed explanation. I understand killing process, shutting down cached process or apps & later restarting them is only going to fire up the CPU usage which completely defeats the purpose of conserving battery.
Though not a daily ask, at times I am stuck in situation where a phone call or SMS is all I need to keep me going.
