Task killer - EVO 4G Q&A, Help & Troubleshooting

Do I need any task killer or they are just taking memory & slowing down the phone ?
Everytime I open it I have a hole bunch of apps running & some will open right away before I Evan exit the task killer ?
I tried most task killers but nothing seams to actually work properly .

I would not recommend using a task killer. Android OS has a built in task killer that will kill apps if they're taking up too much memory. Using a task killer, more often than not, can actually INCREASE battery usage instead of helping it.

Do I need an anti virus ?

No. That's a common misconception brought on by Android Haters. Unless you install random third party apps that seem sketchy, you won't need to worry about any viruses. On top of that, any app that is infected is sandboxed from other ones so they could ONLY affect that app and not others. But the point of this post is no, you won't have to worry about anything. Android is actually pretty safe

many apps you think are running (you see them in the task killer) are not actually running but rather just cached so that they can be opened faster. This is how Android works. True the caching takes up a small amount of memory but you're not wasting CPU cycles on those apps.

Wow thx that's good to know .
Thx to you all here @ XDA you guys ROCK !!!

Task killer for 2.2

Hi guys my 2nd post here. Just updated my phone to 2.2 and was wondering if I should bother using task killer anymore. Someone told me that I don't really need to on 2.2. What are your suggestions since you guys seriously have answers to everything. Thank you.

task killers do more bad than good
You would be better off using a task PREVENTER like "autostarts" if you want to keep open processes down
Froyo won't allow them to kill the app. Only background data. So essentially they are useless with Froyo.

[Q] Can you use the "autokiller" on cyanogen?

Hey guys I was wondering if you could use the Autokiller app in Avalunch's V10 rom on Cyanogen 6.1 stable? Help me out if any one knows or has tried this before thanks!

Can you? Yes.
Should you? No.
Any taskkiller apps should not be used on Froyo on a phone with enough RAM to easily handle the in-memory apps.
Thanks bro!!!!

do you know why? i experience a definite improvement in speed and smoothness after killing all apps (on medium security level) i use the one on the market that says it was designed for froyo.

Froyo is a big boy compared to its younger siblings and can take care of apps itself. 99% of the time, it's opening something in the background because it thinks you're going to be using it soon, or because you have a widget for that app on your home screen.

Cm6 much faster then mikifroyo?

I thought they'd be about the same but like when I click the app killer widget on Cm6 I got almost 280mb or whatever and on mikifroyo only 180mb

that's how much free memory you have available....You should not be using task killers on 2.2 froyo, it does not do anything...

Yes it does......................it drains your battery quicker!
How much memory is left is not = to how fast it runs. CM 6 also only has wimax in alpha, has no hdmi. It doesn't have sense. So of course it has more memory left.
as others have said the memory you are looking at is phone storage this is not the RAM type memory on a computer and it has no affect on your speed. The biggest reason for the difference is the lack of sense and htc widgets/apps. you can get similar memory amounts (though never as much) by removing rosie and htc widgets/bloatware from sense based roms.
CM can run faster then sense in many cases but the method you indicate is not a valid way to compare or tell that it is.

i lol'd at that part, but yeah don't use task killers, it's like this, i have a computer,no better yet an xbox...i have 19/20 gigs free, the xbox will run the same if it has 1 or 20 free. That's just storage space, its not anything else

in short, in 2.2 and above, you kill a task, android restarts it. nuff said. wasting cpu cycles and battery suffers from it
Ok ya that makes sense thanks. What about on other roms like cm or miui? Are they useless there too?
Sent from my PC36100 using XDA App
From what I know anything based on 2.2+ has app management built in so task killers are worthless. So pretty much any of those roms. Don't worry about using it.

My method is not scientific... I have ~ 200 photos on my sd card. I've tryd warm 2.2/ and miks... miks was faster loading photos than warm.
I went to cm6/// then 7 nightlys. The photos load 4x faster. In fairness I loaded CM6 gallery (availble on market) into miks and there was no difference in speed CM is hands down... faster IMHO
I use a start up manager it keeps apps from starting up in the first place. After that a app killer really isn't necessary. I still keep one installed just encase a app hangs for some reason. Yes I have read all the threads about app killers. Also a full hard drive will be slower than one that isn't. It's true that app killers don't really work that well but start up killers will.

What about the task killer in miui when u hold the home button? Is that bad too? Jw and i dont understand how they don't work bc when I first start my phone its slow but once i killed them its faster? I know u guys know better but just hard to beleive... Thanks btw

[Q] third party app or running services show ram more accurate??

When I use third party app to show amount of free ram I have is usually 85mb below,but if I use setting>application>running service to show ram,my free ram is usually 140mb and below...which one show ram better?

third party apps shows free RAM including cached apps...
however, the running services shows free RAM without cached apps...
the running services free RAM is better (IMO) because cached apps can be deleted automatically when RAM is needed...

What is the different in running background service and cached background process? That means third party how more accurate?

It's hard to explain but this is the basics: Running background services are apps that have their state saved into memory so that instead of running their boot scripts they can be switched to near-instantaneously. Cached processes on the other are more calculations and such that the CPU has done recently or often so it knows it may need in the future. IE if you had an app in RAM it would run from where-ever you left it or would be able to continue running, but if you had an apps startup scripts in Cache then it could start up much faster because instead of, say, executing 50 lines of code to get a result it just goes and finds it in Cache.
Feel free to correct me if I'm wrong but that's what I learnt from my father who is in High-Tech and has had much experience (running his own company) in computer hardware.

Which means running services use CPU and battery? Then cached background process is where the memory is stored in ram so later I will need it in future,so it start up faster is it? 0.o

to show the widget, the service must be running... even a stock widget... the service is running, but you won't see it...
no worries if theres plenty of running services... android will take care of it

some apps can get started automatically... its called startup apps
you can download startup manager (available in the market), uncheck all apps you don't want them to start... i did that, and i got a boot time of 51 seconds

there is absolutely no harm IF you disable USER apps... if you don't know what you're doing, do NOT disable system apps... just stick to the user apps tab

Are task killers okay to use?

Hey guys sorry if this is a stupid question, but I heard using task killer has some sort of negative effect? If I downloaded the latest task killer from the market would it hurt anything when I use it? I've avoided them forever and now I'm trying to save as much battery as possible so I figured i'd get a task killer. Any advice would be appreciated

If you wanna save battery underclock and/or freeze active services you don't use.

My understanding is sometimes they kill services that android needs running, causing android to just start them up again and wasting more battery. From my experience juice defender is a better option for battery saving.

If you know what you are doing, yes. If an Android service keeps showing up then set it to ignore or whitelist it. There are still apps out there that once loaded do not release the memory back to the system so killing those is effective. If there are tons of apps in the task killer list then you will notice your phone slow down so that BS about android handling memory is just that. It is also useful to see apps that you don't use loading parts into memory. You can freeze them, list them in Autostarts or uninstall them if they are not really used.
Uninstall it and just use the v6 script set to aggressive.

Sweet thanks guys that's all I needed to know. I spent the last day or so setting up v6 on aokp and cm9 and finally got jd ultimate, but could one of you tell me what I would need to get rid of in the init.d folder to make the settings stick so I wouldn't have to have a script run at boot? It doesn't really bother me I just figured I'd ask
Thanks again!
