High memory being used.

[joe645733]

Hey what's up everyone. Anyone know why there is so much RAM being used on the phone? As soon as I bought the phone without installing any apps, I'll open the task manger and see over 430mb's of memory being used, giving me a little over 100mb's left. I'll run 3 apps, bring it into the 80-90mb's left and the phone gets laggy.

Anyone know why the phone is using so much memory with nothing running In the Task manager? I never see it under 400mb's of use.

Thanks

Is it the same after a reboot?
For my Sensation, I've noticed that after a few times using it and playing with it, the avaliable RAM decreases even if I have no more than 5 apps running
Rebooting the Sensation gives me fresh RAM.

Also you may use a taskiller or task manager, that will show you much more running tasks than what is displayed by the stock HTC task manager

HTC's task manager is not even showing the right amount of ram. Go into menu->settings->applications->running and look at your ram there.

I just pulled the battery out and turned the phone back on. Says 468mb's are being used. Have around 110 availible.

Borodin, thanks. I'll try that. But I've noticed after 5 apps running. The phone will get real laggy. I came from an HTC HD7 and I loved how smooth it was. Not seeing that in this phone much...but still like it.

I'm not saying that it's not ridiculous that Sense 3.0 is using that much RAM, I'm just saying that may be we have more mem available then we think.
In my phone right now:
HTC's readings are 438 used/120 free
Android's readings are 253 used/263 free.

Phone definitely needs a make over as Sense is just bogging it down.

Supposedly has something to do with the 2.3 Android system

Yes I don't know why the two are reporting different amounts. But I have a feeling that the one in the running services is showing the correct value.

I installed ADW ex & checked a few times to see how much ram I had and it shows a little over 200mb free(in tsk mngr). Not to mention this thing is now snappy as hell.

Strange, I can reach a max of 338Mb free (according to a task killer and an external task manager from the market) after a reboot and after having killed all unecessary tasks. I use settings=>apps=>running apps to kill some tasks, and taskiller to kill some other, because both of them don't display all of the running tasks and display some that the other doesn't display.

After two days of (eavy?) use, doing the same trick to kill al unwantesd tasks, I can't go over 200 or sometimes 150MB so I reboot.

Just like most modern os you don't have to worry about memory. Android will take care of it. Also remember, if you're not using the memory its useless. It's better to have 10mb of memory free always as long as you don't notice issues. Apart from apps there are cached apps, buffers and other things loaded to keep the phone speedy. Just don't look or think about it and definitely don't use a task killer.

.....or at least, use a task killer very carefuly if you use one, set it to ignore all the system tasks, and also all tasks the OS will always keep on puting ON again indefinitly if they are killed, your wallpaper, any media related app, etc

(after each reboot, I have Gmail, the reader, news, weather, facebook, messaging, etc opened in the background for nothing, I definitly prefer killing it as they will start again normaly if I need them)

But right, except for N64oid and Fpse, I have never been bothered by too low RAM on the Sensation. And when that happened on these 2 emulators, it was after 2 days of heavy use without any reboot, so....^^

I agree with you 100%, and again with your comment about the task killer. Don't install a task killer, and don't obsess about killing about with the built in task killer. Since 2.2 android has done an amazing job at managing and using available resources. It's pre-loading services and apps into memory to have things launch sooner, etc. When the system runs out of available memory it will kill whatever apps it feels it needs to kill in order to give the smoothest experience possible.

The only reason I have a task killer now is if anything is loading for no reason. With that I found that VTOK & Movies by Flixster were always running & causing the phone to never sleep & draining my battery. They were always listed as in the foreground (along with Tmobile's Wifi Calling & MyAccount apps).

Bloatware!! The sooner it can be removed, the better.

I've noticed that rosie uses alot of ram on every sense build. But 3.0 is a little over the top. It gets killed quite easily as well after using the xda app, browser, and download manager for example. And then sense has to completely reload... Htc obviously noticed it a little late in the game and was quick to make miniscule changes in a desperate attempt to conserve ram usage. No scrolling wallpaper? On a dualcore 1.2ghz processor? Really? Lockscreen lag? Lag at all? Can't wait fire a cooked sense 3.0 rom. The difference will be tremendous!

Android is at its most efficient when the memory is being fully utilised. Don't think of memory usage in Windows terms.

Ask and you shall recieve, and that's what HTC just did. The no-scrolling wallpaper is considered a UI feature just as it is on the Galaxy S 2. It's also standard on ADW-EX and Launcher pro. I personally dig the stationary wallpaper.

what have you got so bad against task killers??

You just say "don't use it", without any explanation....

I use one, like I do on my 2 other Android devices, my Sensation is extremely stable, and I don't want to lose fps when I use Fpse or N64oid, sorry to tell you you're wrong: having less than 150MB ram, because many apps are running in the background, when starting one of these 2 emus, makes fps drop, or frameskip less efficient.

Try it yourself if you don't believe me.

Sorry, I don't use emulators. I also don't have a sensation, so I can't comment on gaming on one. I have however played just about every game imaginable on my SGS1 and have never had to worry about closing an app to play any game. The main reason why I tell people like the OP to not use task killers is because they tend to begin automatically killing tasks(the people using them, not the app on it's own), and since the newer versions of android behave they do, those tasks just end up starting again which then leads to an endless loop of task killing, and battery drains for no reason. I also make it a habit of restarting my phones once a day or two, so I never really give the devices to get bogged down with extra crap running. I'm just saying that's my experience. If you like it, then so be it. Kill away.

Another thing you may want to try is, backing out of all of your running apps instead of being addicted to the home button. Home leaves the apps running and using resources; Backing out closes them and keeps the universe in a zen like state. I love the home button, when I know i'm going back to use a certain app immediately. If not then I back out.

 

[i900frenchaddict]

allright, I agree with what you say.

Luckilly, I've set my Taskiller not to endlessly kill tasks that always start again (and actually, Taskiller doesn't display them, or don't kill them automatically or in one click on the widget, only if you go to the app itself and select force kill, what I never do knowing they will start again asap).

I mainly use it, from its widget, to kill everything related to messaging, gmail, facebook, reader, tutorial, etc, that tend to start automatically and never stop when I connect datas or reboot the Sensation.

I also most of the time try to back out instead of home button, but for a few apps, it may be loooonng because it will display a lot of pages back before killing the app.

As for newer versions of RAM management, it also depends on the ROM I suppose.
With my stock SFR/Vodafone french ROM, after, let's say, 2 days of use, the RAM goes under 170Mb, even if I close all tasks, I don't know where RAM is drained, I'm pretty sure my stock ROM is responsible for it, so I reboot every day or every 2 days too.
