Question on ram - Galaxy Tab 2 Q&A, Help & Troubleshooting

I just got my gt2 10.1 a week or so ago and have a question. When I open the task manager to close any running apps I click on the ram tab and here is where my question comes in. It says I have 687MB of ram. Does that seem right? I know you will never have the advertised 1gb but my number seems a little low. Do I have a hardware issue with my tab? I removed all the live widgets from the home screen and it helped to make it smoother, I just don't wanna regret getting this tab later.
Thanks guys

When things are running normally with Android you should see about 80% of the RAM in use. The memory manager attempts to keep things in memory so they start faster. you have more than 50% maybe when you first boot,. but as things run it will go to about 80% used. That's optimal you can kill task all day and it will come back. That's the way it works and optimizes RAM use.
And oh, by the way , that's typical for modern virtual memory systems, Linux, Windows etc.

Ok bro. Thanks for clearing this up for me. so it's all good then.

Running services

Hey.
Just wondering with people out there. if you check under running services, how much are processes taking up and how much free do you see on average.
I see 150-170mb
140-160 free
Are these numbers normal is what I'm looking forward to see.

127MB used 179MB free
Is that avg? I get that right after I reboot my phone. After some use it pops to 150+

no thats just what it was at that time.
its now 130MB used 177MB free.
no reboot.
I hover around 90ish used 210ish free most of the time. I close apps by back buttoning out of them when I'm done instead of home button.

Holy crap. I avg about 160 used. Idk if battery life is an issue though. Been getting ~15 hrs on moderate use.
Sent from my Nexus S using XDA App
WHOAA! 160s and some even in 200s?
I get a max of 170-ish at boot, and soon after some use, it deteriorates to to 60s and 70s range...
i reboot my phone once every 1-2 days ... but i constantly ensure there are no background apps running using the task-manager app...
any tips to help me out guys?
EDIT: sorry - i was looking at "Free memory" as shown under the "Advanced Task Killer" app ... while the OP was talking about free memory shown under the 'Running services' screen ..
that screen shows me around 130-145 ish
From what I hear atk are bad for your phone causing the CPU to be used more to end these tasks that aren't ready to be killed. I suggest you let your CPU run off its terminate code on its on. I'm confident you'll find the stock task manager to be efficient and effective.
Anyways, back to services. Seems like nightly #19 is better taking care of my services. Got it to drop to 120 consistently and staying there.

mmmm..interesting..
i just checked the built-in battery-usage app to see what's consuming power... and ATK hasn't popped on there (yet) ... but I do rememebr seeing it once or twice with a 2-3% figure next to it..
I will try to keep it off tomorrow and use the stock task manager... lets see if that improves battery life by any chance..
i'm not sure that task managers will show up in the android list of used battery processes. but i can tell you that using task killer is a bad idea, and can lead to shorter battery life, because the OS constantly opens up apps. and the task killer is just fighting the OS killing them again, which is an endless cycle using up cpu power. these apps are periodically loaded as "empty processes" and usually will show as background on a task killer. you dont have to worry about these, they use no power. but services you may want to look out for, as they may be doing something, and could be using power.

[Q] about ram and multitasking

Is ram availability on this phone based on time or physical availability?
Sent from my HTC One X using xda app-developers app
What do you mean time? Ram is a physical limitation. But since sense is hogging up quite a bit atm, we might be able to squeeze a bit more free ram in the future.but 1gb is fixed.

I know it's physical but some of my apps don't hold their spot after time vs availability of free resources.

Apps only get dumped from the RAM by the OS when the OS runs out of RAM to use.
So just time wouldn't affect an app getting dumped from the memory. Your problem is probably stemming from an app that continuously is using up more and more RAM.

Actually, Sense also kills apps after a certain time limit (around 10-15 minutes) even if there is sufficient RAM. So, to answer the OP's question, YES, the physical limit of RAM as well as the arbitrary HTC Sense "time limit" will both kill a back-grounded app.
You can test this yourself easily. Reboot phone. Load two apps, then make note of your RAM usage. (You should still have a fair amount left with only two apps open.) Let phone sleep. Open phone 15 minutes later, verify RAM is roughly the same as you left it, use recent apps key to select an app, and boom, one or both apps will reload. :-(

not true. the OS will dump an app if its been idle in the background for too long even if there is a sufficient amount of free memory. I post a similar thread about it the other day.

Just found a way to substantially increase smoothness

under Developer Options--> Limit Background Processes
I set mine to 4 and notice a difference
Great find, ill try it out
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Yup, been using it since my vibrant. Cuts the running background app usage down from 45+ to whatever I select (4 in my case) thus freeing up and keeping a good amount of RAM freed up.

We have 2gb of RAM. I have zero stutter. Why do you feel need to reduce background apps?

In my case, I have anywhere from 35-45 background processes running at a time and 1/3 seems to be bloatware. There's no need for unnecessary processes to be hogging up any amount of RAM.
So if heimdall worked on the mac for our U.S. variant s3's, I personally wouldn't have to do such a thing.

would this reduce battery usage too? I find I always have a bunch of programs running in the background when i go to the task manager (programs that dont close down after i leave them) and fear they might be draining battery.

in theory yes it should as the task manager is continually working.
In response to the "do you put low test gas in a high performance car" ... I sort of agree but...
I wish there was more of a choice than standard (which appears to be around 48 to 50 background apps) and 1, 2, 3 or 4....
I would like to set it to maybe 15 max, 4 seems far too few.

If you're worried about bloatware you can disable it under the Settings -> Apps -> All
Select the app in the manager and hit disable. Removes the shortcut and stops it from running.

Is it me or is my S3 getting laggy?

Maybe it's me getting used to the speed of the new phone, but in the past month it seems to be running slower or acting more laggy. Any way that this can be checked? I have not heard of anything. But maybe I missed it.
Sent from my SCH-I535 using xda app-developers app
either its you getting used to it, or youve bogged it down with crap.
Phones dont just get slower on their own.
Did you try disabling sync? I had mine disabled, and was still getting notifications from facebook/xda etc, so had to go to those programs and check off notifications. Even after I would turn off/on or reboot, seems like those are still starting up running in the background.
Download an app from the Market called "App cache cleaner" run that. Also backup then delete your old emails, sms, call logs etc...if they are growing big. My wife had 5000 sms on the phone, so when she opened sms, she said it slow, but not after I delete them all. Good luck!
Thought of rooting? I didn't really play with my phone without root that long, but rooting and installing custom roms made it really smooth, especially when it's jelly bean. But even when it wasn't, it's still smoother and faster. Just a thought.
Sent from my SCH-I535 using xda app-developers app
ive noticed a bit of lag here and there as well. those 2 gigs of ram don't do much for me at least. seems touchwiz uses almost a gig of it. still a beast of a phone though.
You could go to developer options then set window and screen transitions to .5x. Everything should be a bit faster

+1, before I rooted and ROM'd this helped noticeably speed up the phone. Definitely try this. Also, try Nova Launcher as a home screen replacement. It's very refined and has even more window and screen transition controls. There will be no lag at all.
its all in the setup...no device out there will stay fast if you have a hundred background processes, overloaded app cache, and syncing data to multiple apps.
Nova is fantastic on this device. Stock it should show a noticeable difference. Rooted running synergy with transition speeds all maxed out - unmatched. Phone is fantastic. I agree with post above, clean that cache. Also remember, all the verizon bull sh*t runs all the time, though you'll need to root to stop that.
Side note: sd speed increase (the dedicated xda developers one, not ones thrown into a multi use programs) works very good. Support are devs here and give it a try

If you're rooted, you can use Greenify to hibernate apps that you want accessible, but not necessarily running in the background.
Samsung's TouchWiz is a heavy ROM, and there's probably a lot of features that are running that you don't use. Turn them off in settings, hibernate them with Greenify, or disable them entirely in your app manager.
Other than that, just leave it be. Apps that you use frequently you want to keep running in the background, and yes, taking up RAM. This way they quickly load. Apps running in the background don't drain your battery significantly, but loading them up every time you want to use them because you've killed them with a task manager does.
Don't obsess over RAM usage. RAM is there to be used.
thanks sir ..
