So I installed automatic task killer just to see if I noticed a difference. So it says it is freeing memory when I engage it. Great, more memory available seems to allow the phone to run smoother/quicker. However, give the phone a couple of hours and gradually the available memory on the phone lowers and lowers until it goes below 100mb and beyond. Engaging automatic task killer frees some memory but does not bring it back to its startup memory of over 150mb. I of course do notice that my phone begins to get "laggy" once I start to dip below 100mb. I guess my question is, "where is all my memory going?". Im not too concerned about using automatic task killer. I just want to know where my memory is going cause this is most certainly the cause of a laggy phone. A quick reboot and my phone is back to its highest point of 158mb and running nice and smooth. What gives? Also where are the other 150mb or so that the phone has available according to specs? If its all dedicated to the the android OS than why is the phone so laggy by the end of day? Sorry if its too many questions but im just looking for some insight into the memory management of the x10 and android. Maybe a 1.6 issue?
It's nothing to worry about. Unused memory is useless memory. It's *nix based so the memory in use isn't going to drain the battery or slow the system down. It manages everything by itself. By repeatedly killing tasks you're actually stressing things unnecessarily.
The only time you should kill all the tasks is when you know something is being problematic, before locking your phone when you have a suspicious app that doesn't always stop automatically, etc. Otherwise the Android OS takes care of this by itself.
I stopped using task killers months ago (except for when I lock my phone because of what I mentioned above.. programs keeping it from going into a deep sleep) and my battery easily lasts two days with periods of very heavy usage.
I only use a task killer to kill certain things when they cause problems, which is not often. Things I use often I leave in memory, they only get reloaded anyway.
Tbh if things are getting laggy that quickly you probably have an app that is misbehaving.

Thanks for the quick replies. Automatic task killer has already been uninstalled. Looking forward to the update with hopes that it helps with lag issues

Well that still doesn't solve the problem of badly written apps draining the battery. Often I've found that without a task killer my battery life has improved, but on occasion when I download a new app, I look at my battery usage a few hours later, and that app has managed to use 45% of my battery even though I used it for a few minutes. So then I just reboot
In conclusion, don't use a task killer, but keep an eye on the battery usage feature if you find that it has suddenly gone down (Settings -> About Phone -> Battery Usage)
I use Memory Booster. Quiet amazing.
hi i used to be same as you and always used talk killers
then i came across this article http:// www.ipmart-forum.com/ showthread.php?t=528674 (watch for spaces in the link)
since reading this i installed watchdog lite and i only kill a task if its overusing the system.
you can set it to notify you when an app is using more than a certain % of resources and its great then if i need to i just kill that app/process

that doesn't work all the time is kinda annoying to keep checking your phone and see if the battery is alive or not

K i seriusly need some answers how the hell do people come to know which app prevents it from sleeping? how can you figure out a bad application . does sleep here means when locks itself and screen goes blank? confused :S

I have read that taskkiller is not necessary on Android as the OS will kill off running apps when it needs memory - what are people's thoughts on this?
Hmmm...I read somewhere (maybe on here) heard if the App is coded properly that when not in use it will be background so not take up memory.
Not too knowledgable, but in that case would imagine they are acting like a windows service so will be taking up memory somewhere....so perhaps what I read was nonsense
Well, I have stopped killing tasks and guess what - I notice no difference at all! Hero is just as speedy (or slow depending on how you wanna look at it!).
Interesting!
Killing truly idle applications wont have significant effect. There are however many applications which appear idle, but still drains resources. An example is Peep, the twitter client, which starts automatically even if there's no twitter account configured. It has some frequent checks that put load on the CPU and thus helps drain power. Killing it adds many hours of standby time.
i'm not using any task manager/killer, did try them for a couple of days, can't really tell the difference, except i was wasting time constantly killing apps :/

Ditto... surely there is no need as the OS will kill a unused app if it needs the memory ??? I don't have any problem running any apps one after the other... they just load.
The only lag I get is while the handset starts a widget update, once they are started everything runs slickly.
I found it a little slicker without taskiller. Especially in the use of big apps like copilot or documents2go. It seems to be managing itself pretty well.
Yep. I can report that the phone is working very well without Taskkiller. I have uninstalled it now.
If you are reading this, give it a try for a few days and tell us what you think. You may be pleasantly surprised...
Ditto - I've removed taskiller so I don't get tempted. Surprise surprise, no problems, no lag, etc. Now mostly this is due to removing the clock and people widget, but memory management seems fine after playing many different games and browsing the internet.
I think a benefit to doing this is that you aren't going to get and bizarre problems caused by killing system processes by accident - ie you won't miss alarms or stop receiving email alerts.
Hi,
Since I read up on how the Android OS works I have not used TaskKiller or similar and the OS works great (MCR 2.8).
I think these task killer apps are redundant.
Anyone actually think they are needed at all?
It's true that the system will kill apps itself when the memory is needed, but a side-affect of having 192MB available to android, is that there will be a lot of open apps before that happens.
While some apps will become 'frozen'/ only taking memory and no cpu time, other will not.
Having these apps in memory, and using cpu while not needing/using those apps, will drain the battery faster.
In such a case, a task killer will be useful.
It may do more harm than good though, I missed an alarm because I killed the clock app once
short answer: no, not needed unless an app is draining the battery while the app is not used/necessary.
Theory is one thing, reality is another.
When I hit the 'kill all' button on taskiller my phone definatly speeds up, sometimes it's essential when an app hangs(phandroid has gone like this recently) or is rather resource heavy (like sky map) as the phone gets rather laggy untill it's taskilled.
yeah, what she said ^^^
If an app is still using cpu after you closed it, then (task-)kill dat motherf-
I've got Taskiller ocd! Less stuff running definitely keeps your phone running nice and fast so if I'm not actively using an app then I kill it. Although I do have all the important stuff on the ignore list so the phone doesn't crash... or I miss an alarm like E2K
I'm currently trying to decide which app I like best for the purpose, Taskiller Full or TaskPanel.
TaskPanel has more useful options like Auto-kill however I think it has a bigger memory footprint than Taskiller.
Hey all, do you use Advanced task killer or some related app on honeycomb? I use it on all my phones (g1, etc), but i have't on Vegacomb 1.6, and honeycomb does a damn good job of managing mem and running apps.
I use Advanced Task Killer to keep the memory freed up, also because of it's feature to kill all unused tasks every 30 minutes.

Like he said
I know lots of people will say not to use, but I have always used it and do find it makes a difference.
I used to use it until I discovered the difference it made. My battery life skyrocketed without it. The apps that ATK killed would resurge, only to be killed after 30 minutes, and the whole battle between apps, services and ATK would drain my SGS' battery life (which wasn't stellar to begin with). I'm happier without, actually.
I use advanced task killer otherwise my battery on my Vega goes really quick. It works well on mine! then again as you say Honey combs pretty good with memory and running apps already...

From what I heard, it is no longer needed with the newer versions of android because it manages the tasks quite well on its own. Maybe if you have issues with apps that regularly hang? but otherwise it shouldn't be necessary.
Over the last couple of days noticed run time has decreased. In battery stats it shows Android System is using 53%. Does that sound right? I usually close apps if the phone is going to be unused for a while.
It may happen if you have installed too many apps and there are many background services running on your phone.You can also use a good task killer to prevent your phone from getting high cpu usage

The last week or so since I got my HTC One Max, I have been slowly configuring it and setting it up to my tastes. On my previous phone, an HTC Rezound, I used an app called Clean Master to manage the phones ram, and Battery Doctor to extend its battery life. I tried an application called Battery Guru on my Max, but it actually drained the battery faster while the phone was not doing anything. After uninstalling it, my battery life seems to have shot upwards. I have not re-installed Battery Doctor. I have read the following things about these battery saver apps over the last few days:
1. Some say the applications are not needed and you should not use them, especially if they include a task manager. The logic was that Android was designed to have multiple apps in memory all the time, and closing them, then opening them again from scratch, uses up the battery.
2.Others have said just the opposite. They claim the applications greatly increase battery life. If you read the reviews on the Android Market about these two applications, that seems to be the case.
Both of these applications I have used get rave reviews from the many folks that have used them. Is the benefit they are seeing just imagined? Do the applications actually work? Is it also possible that they work for some and not others, since there are a lot of models of Android devices out there?
Most things that are ram "cleaners" are just giving you a slight point in time speed boost. Your ram will fill up again (as it should). Most so called battery doctors cripple your phone to extend battery life (think extreme power saver on the Max). What you want is something that blocks the applications that you do have running from performing activities in the background that you dont need at that moment ( think facebook looking for your location even when not using it just so it will know it faster when you open the app).
I use a combo of firewall to block most apps from using the internet (radio takes a lot of battery) and greenify which hibernates the app while keeping it in ram so it brings me into the app where I was before.

Try greenify

Free ram is idle ram. Having a lot of ram usage isnt a bad thing... Don't know how many people think the opposite. Now if it gets too high then yea its an issue when opening new apps but this issue died with gingerbread in all reality. Some would argue task managers even died with froyo.

Thanks everybody! I have installed Greenify, and removed Battery Doctor and Clean Sweep, and my phone is running great! I like it so much, I have put Greenify on my other Android tablets. No more battery saving apps or task managers for me!!
The trick is to properly manage the apps that you use.
The problem with task killers is that some apps that you kill will simply "respawn" themselves automatically in the background. Killing apps that do this just means your phone is constantly closing/opening the app again and again which is worse than not killing it in the first place. You will just have to experiment and check which apps respawn after killing them and avoid having the task killer auto-kill those apps, or uninstall those apps.
You also have battery saver apps that try to manage turning certain features on/off like WiFi, GPS and Blutooth. The most efficient way of managing this is to manually disable those features when you don't need them. Having an app do this for you means that app now has to be running all the time to manage those other features, which itself will ironically increase battery usage.
Avoiding as many apps as possible that need to constantly run in the background to perform it's function. These mostly include instant messenger apps or other apps that regularly check the internet for updates in the background. Either avoid them or if possible increase the delay between how often the app checks for updates/info. The Greenify app will allow you to "suspend/pause/freeze" specific apps when they are not currently on your screen. This keeps them from performing any activity in the background, and will help save battery if used on apps that would normally be doing tasks in the background. The downside is that if that app is suppose to be doing something while in the background, it won't be doing that anymore...like checking for updates, chat messages etc...
Keep screen brightness on automatic, so you don't waste power on a bright screen when in a darker environment.
These should be more than enough tips to help you better manage your battery.
