[Q] Total memory less than 768 MB???

Can anyone explain the amount of RAM that this phone is suppose to have?
The specs for the phone lists 768 MB. However, the total memory that comes up is 617940 kB.
Thanks.

where are you finding this number? i am at 758 MB. since i have a bunch of apps installed, that would seem about right.

How are you guys getting so much free ram? When I check on Task Killer, whenever I kill all the apps I'm not using it usually shows 358 mb ... and programs I'm not using automatically keep running (i.e Maps).

hmm maybe im not checking the right place? i'm getting my 758 mb number from settings--SD and phone storage. the internal phone storage tells me 758mb.
on an unrelated note though, you shouldn't use task killers. they are considered by most to be more of a drain on your battery life as android is already setup to manage closing unused apps on its own.

Many people use the term "memory" to mean system memory as well as storage. I try to avoid calling system storage as "memory" and tend to use "storage" instead, or refer to the type of storage.
Total ram is around 768mb. Part of it is reserved (not sure why, possibly for filesystem caching) so around 603mb is available. For this platform that is a healthy chunk of RAM to work with. Even with my hefty usage I have ~126mb free.
Internal storage is something like 2gb, with it partially consumed by the Android install as well as NAND configuration adjustments for reliability which cause some of the storage space to be consumed through hardware (there's an excellent explanation of this somewhere, don't have a link handy), resulting in about 1.1gb being available. I have 103 apps installed, 523.5mb of the internal storage used, with 638.8mb available.
There was an excellent tool posted on xda (http://forum.xda-developers.com/showthread.php?t=1066060) called Android Optimizer that gives a lot of good information about memory, storage, cpu usage, etc. I'd recommend checking it out. It's not available on the market and it is a little buggy so use it with a bit of caution if you choose to use any of the optimization functions.

cool. thanks for the explanation nimdae!

There have been so, so, so many posts on this topic that I will not rehash them all here. Instead, I will ask a simple question: For what do you use all that free RAM?
Ask yourself that question, and be serious about it. I think you will find yourself uninstalling your task managers and memory optimizers before long.
Edit: to avoid unnecessary discussion, Watchdog is in fact neither of those, and I would highly recommend it as the only memory app you will ever need.
Edit 2: the total RAM displayed is the RAM that is actually available to be used by anything the user may want to run. As a poster earlier said, the system reserves a certain amount of RAM for its own use to keep important processes moving along. The reserved RAM is not available, and so doesn't appear in total RAM. Unless you want to uninstall the OS. Then you could have access to all 768 MBs.

I would like to reiterate why you should not use automatic task killers.
As of, I believe, Android 2.0, the garbage collection and memory management was significantly improved. However, this was not a new system in Android, it always existed.
How it works:
If you haven't noticed with Android, when you leave an app, it doesn't close it unless the app specifically does something to end the process. This is by design. Android allows the app to remain in memory. Frequently used apps will load faster with this design. A "task" that is not killed and is in the background ONLY consumes memory, it does not "run" (in Linux terms, the process is actually in a "stopped" state so the task can't do anything anyway). Only a "service" can run in the background. Most apps that have long running services have lightweight services.
If an application loads that requires more memory than is available, Android will examine backgrounded tasks for candidates to be killed to free up memory. This makes it so as many tasks as possible can remain in memory for better performance. In understanding this, you should know that if you have a large amount of memory, and memory usage is high, this is a GOOD THING. With the amount of memory in the I2, there is a lot of breathing space for this.
There is one other case where a backgrounded task will be killed: if it has been in the background for a certain period of time without being brought forward. Killing a task to free up memory to load another task can actually be a little cpu expensive (but not THAT much) so this can make it slightly easier.
Please note that backgrounded tasks WILL NOT contribute to battery drain. Only tasks at the front and services will. Killing your backgrounded calculator will do nothing for you other than free that small amount of memory it uses. Used memory does not contribute to extra battery drain as DRAM refreshes happen on ALL cells anyway.
Background services can also be made candidates for being killed. If an app needs more memory than can be made available by killing backgrounded tasks, then services become targets to be killed as well.
Automatic task killers cause a couple of problems. A less major problem is you lose that one benefit you get by keeping tasks in the background: performance. I don't just mean how fast it loads. If it can bring a backgrounded task to the front from memory rather than load from storage, you remove extra processing to load the app, including storage access, that contribute to higher battery drain. The other problem is a poorly configured task killer can break things like notifications.
Managing your services is always a good idea. Having a lot of services running means background processes that are capable of contributing to battery drain. Additionally, there are apps with misbehaving services (services that consume resources or use features they shouldn't). While I'm against automatic task killers, using something to monitor and manage services is a good idea. Just always keep in mind the implications for killing a service: it may affect a feature to an app that you would rather not impact.

Excellent explanation nimdae! Task killers are the devil.

Remember: I'm not saying don't manage things. Poorly behaving services are the #1 cause of high battery drain (at least on non-LTE devices), and this will be even more problematic when you overclock.

If you get that much extra, you have a misbehaving app. Better to get the app developer to fix it or find an alternative.

CyanogenMod (maybe other ROMs) have a feature to kill a frozen app by holding the back button (long press, whatever). However, this can also be an annoyance on systems where for unknown reasons it registers a long press on a tap (my eris did this a lot).

[Q] Memory management

Hi Arc Users,
Do you guys encounter low memory after long period of usage? It seems like the memory does not free up after using the phone for a long time. I mainly use the phone for FB, Camera and messaging.
When the phone hits like 50+MB ram or so it starts to slow down and if it goes lower than 40MB my home screen starts to lag and the app icons take a few secs to load every time i return to home screen. I'll usually reboot the phone but its quite a pain considering the boot timing for my phone is rather long, like close to 1 min.
What are the possible solutions? I've heard that advanced task killers are unnecessary for Gingerbread. If thats the case, how do I free up more memory or have better memory management for the Arc?
Am a first time android user, appreciate any advice from you guys
Thanks!

Root is the solution. Delete apps and services which you do not use.
I haven't any problem either when free ram goes down to 30MB and i don't use a taskiller.

Just what are you doing when you run out of ram? Never did I run out of ram yet. Running ram hungry games will free up more what is needed as I experienced. When I return to homescreen, it takes a while (around 2 secs) because it will free up ram from the game, then load the homescreen launcher from start/scratch.

Same here but my Arc works fine, even with 30-40MB RAM, so it isn't a real problem.
But it would be nice from SE to make 400-450MB of the 512MB RAM available for the user.

What? That is a completely pointless excercise if you understand how ram is handled by the os.
You need to root and remove bloat, check ya settings etc to get better performance. I found letting things constantly access the network was a juice eater, I don't want fb to check every 4 seconds, I update it when I want to read it lol
I use a task manager, but only because I like to see what is running and using resources. I rarely actually kill any apps, just occasionally a few things I rarely use. Even then it fills the space with other stuff.
:edit: sorry flo95, that sounded a bit crappy, no bad attitude was intended.

I do not play games with my Arc. I just used facebook, MSN, Camera and messaging occasionally throughout the day. Medium usage.
It runs smoothly for several days but maybe after a week or two, the RAM starts to get low.

I use battery guard as a task killer. It comes with a widget where you can see the available amount of ram.
I'm happy about it. Though a lot of people say a task killer doesn't help I have no negative experience using this one... and I never go below 130 ram.
I still think it does help to close tasks that otherwise keep running in the background... But I'm new on android so I could be wrong.

Hey guys
Have you tried this script
http://forum.xda-developers.com/showthread.php?t=1111145
maybe this can help w/o having to install apps or task-killers. Should work on Xperia Arc but I don't guarantee it.

That script seems to do basically the same thing as auto memory manager.. (per my previous post..)..

How do I stop apps auto opening

The title is basically the question, im fed up of alot of programs auto opening on my android phone, it takes battery and is slightly annoying receiving notifications off apps i dont really care about such as the NFL game tells me about small things in the NFL, im in the UK, i dont care.
If you argue that it doesnt take alot of battery currently have 117mb free ram, (2 secs later) killed all my selected apps now have 201mb free so im using 80mb of ram on apps im not using. Ive made 2 or 3 phone calls today no more than 30 mins long altogether and ive lost 55% of my battery since about midday, which is when i unplugged the phone.
And I think all these apps are the problem so how can I stop them from auto opening, please help

More free RAM doesn't really equate to longer battery life or lower power consumption.

Better search for auto starts, this asp shows you the conditions an asp can turn back on and you can bin it off, Facebook for example had like 8 conditions, from full to medium battery life, on charge and change in network....... Use it

There's still no reason for most of this apps to use RAM. Apps like facebook and skype shouldn't be actice without user permission. Without login they are complete useless.
I'll try Startup Cleaner, thx.

It's how android works and what RAM is for. There is always a reason.
Sure if someone doesn't use Facebook, it should be uninstallable, but its not and its not causing any harm

The problem isn't that apps start when I turn on the phone its that even after i use task manager to close they keep reopening and use over 100mb of ram, earlier I checked and only had 78mb ram available.
This must have an effect on battery to some degree i want to kinda ban certain apps from running in the background unless i specifically tell them to

RAM doesn't use more power, the more its used, no.

Thanks for you reply but its not really an answer its more of a contradiction, what I was asking is how to I stop apps from auto starting and eating up RAM, regardless of how long the phones been on

...and I'm telling you its a pointless, unecessary waste of time. Also it is not possible. Autostarts as already mentioned is the closest you'll get

I also turned off the autorun permissions of a lot of apps, for 2 reasons: 1) a device that is smooth sooner after booting, using less cpu cycles/power. 2) preventing Sense from reloading due to RAM shortage and have smooth multitasking.
1) Android loads a bunch of apps to the RAM that have the autorun permission, until it thinks it is "enough" and useful to you. No matter how many apps you have installed, the amount of free RAM is always about the same, just the number of "unwanted" apps in the RAM differs. Removing the autorun on boot permissions prevents the loading of unnecessary apps that will immediately be removed from the RAM the moment you start the browser/a game, saving cpu cycles=power. So for me there is no point in loading them in the first place, because I am never going to use them (right away). I want the apps that don't to any syncing loaded on demand.
2) I hate slow multitasking and I hate it even more when Sense reloads because it got kicked out of the RAM after each time I press HOME.
I use 3G Watchdog (~12MB RAM), Unlock with Wifi (~8MB), Whatsapp (~15MB), Handcent SMS (~18MB), Droidstats (~13MB), Extended Controls (~12MB), Battery Monitor Widget Pro (~13MB). Okay, I maybe could delete some of them, but these app are "OK" to me, because I use them actively or just need a background service to operate normally.
With Gemini I disabled apps like Facebook, a screenshot tool (just load when I want to make a screenshot..), various public transport planning tools, etc from autostarting.
No joy moment: after using the Facebook app (market version), it may take up 50+ MB and it will not be closed when I start another RAM intensive app, because it is a high priority service. Result: Sense gets kicked out of the RAM. Or, when the situation is somewhat less critical: multitasking is as good as unusable: switching between apps makes them load over and over again, because app2 kicks app1 out of the RAM and vice versa, causing unnecessary lag. Therefore: when I am done with facebook, I close it, then STAY the hell closed It may only autostart when it receives a push message. In that case it is nice to have FB already in RAM when I tap the notification.
Why do even some games have background services, or the Engadget app, or .. , or... all eating precious RAM. And yes, I know, once IN the RAM they eat no battery, but they DO eat battery when the app loads itself back in the RAM when it thinks it needs to, after it got kicked the moment I decided to so something else.
Hmm, spent way too much time to try to explain my frustration Oh and by the way, I have a Legend, but the basics are the same of course.

Dwnload an app called internet commander from the market. It shuts off the internet when your screen turns off but still let's you get calls and texts. I've got my phone , rooted of course, clocked to 710 and my battery will last for days.

The guys here have already suggested you use a certain program from the Market. Have you tried it?
Regarding the whole RAM consumption issue, Android has its own built-in memory management system that ensures that there's always enough RAM for an app whenever it needs it, even if the memory manager shows like 40 MB free. Basically it "ejects" all background, unused apps, from memory making room for the foreground app which needs it most. If for some reason you need to fiddle with that, you can try using the V6 Supercharger script. I find it suitable for my needs but YMMV. It's completely reversible, so if you don't like it you can uninstall it just like that.
P.S. - I agree with rootSU, the ammount of free RAM has nothing to do with battery consumption. If you suspect that an app is draining your battery, check Android's battery statistics to find the culprit.

I respectfuly disagree. Android built in ram management is just silly. If I open xda app for example (it could actually be any app for that matter), reply to a few posts, read a few more and close it, why does it need to stay in ram? It reloads anyway when I run it again after I've closed it (using the back button or the actual exit command in the app itself). Why does the camera app need to stay in the background after I just shot a few photos and closed it? Because I may or may not use it again in some time? It's rediculous. And the whole theory that ram management doesn't require any power/cpu usage, how do you guys think all those apps get killed? Android will power?! No, kernel scans all running apps and kills the ones based on built in heuristics so it also reads them first. So that doesn't require any power/battery? Awesome if it's true! Although I wouldn't bet on that. And all this fuss just because you may or may not launch the same app sometime during the next day/week/month/year or it'll eventually get killed? Now that's just plain stupid. I get apps that need services like widgets, push notifications etc. but random apps like root explorer, xda app, titanium, youtube etc. which are opened specificly by the user shouldn't be in ram just for the sake of it after they're closed. I closed it, meaning I don't need it anymore. And I don't need the kernel to scan all apps and running services every time I launch an app so it could provide the free ram that app needs. Consumes cpu time, battery, i/o ... every piece of hardware actually just to free some ram that shouldn't be occupied in the first place. Every app that I ever opened on my phone got loaded almost instantly and that's just after phone had been booted. So after that it should stay in ram so I could open it in a blink of an eye instead of instantly? That's just funny.
Anyway, I'm just thinking out loud so don't flame me immediately. There probably are apsects of it that I didn't mention here or am not aware of. And I'm not saying that I'm right and you guys are wrong, I'm just saying what I know and think about this subject.
-. typewrited .-

PlayPetepp, while it might be true that the OS allocates (thus use) some resources to memory maintenance, the impact on battery life is negligible. In the Android OS, apps in memory are ordered according to priority and state, so the OS always knows which apps to kill first if it needs to make room in RAM, without much of a hassle. The only bad consequence of this system seems to be the fact that once the memory fills up, the launcher may lag or even be evacuated from memory. But, as i've mentioned in my previous post, there are ways to prevent that, either via scripts or, if you know what you're doing, via editing system files.

So the OS doesn't need to scan anything as it keeps everything in memory again? Seems like an endless loop. Open, sort, kill if needed, reopen, sort again, kill ... to what end, constant unneccessary multitasking that user is unaware of? I really don't see any benefit of that system and am only seeing the downsides. I mean, who needs every app they ever run remain in ram even if they close them after using? And then opening another app and "waiting" for whatever needs to be closed to get it running. Sure you can mess with the scripts (init.d, init.rc, etc.) but the underlined conditions stay the same. I hope I'm making sense here. Or am I fighting against windmills.
I just figured out that I strayed from the topic of this thread so won't be continuing this discussion if it's considered offtopic.

Hello again nice to see you here
Here's an interesting article on what I was talking about. Sense 3.5 doesn't need that many mbs of ram to work smoothly. After booting and setting everything up I have 150+ mb free. That should be enough for decent multitasking but all those apps not getting killed when you close them are eating too much. Can anyone explain in detail what hidden app, perceptible app, backup app and heavy_weight app means? I've been googling this for a week and can't find any decent explanation.

@PlayPetepp - I think i have already said (in my previous post) that the OS does indeed use some resources for managing the memory, but they are negligible in terms of their impact on battery life. IMHO, the only thing a 3'rd party memory manager (task killer) WILL do is improve lanuncher responsiveness (lag) as the lag does increase when free RAM drops under a certain limit. Thus used wisely, a task killer can improve responsiveness, but battery life... very little, in rare cases (it does the opposite, most of the time).
Regarding the so called "memory slots", here's an excerpt from this article:
FOREGROUND_APP: This is the application currently on the screen, and running
VISIBLE_APP: This is an application that is open, and running in the background because it's still doing something
SECONDARY_SERVER: This is a process (a service that an application needs) that is alive and ready in case it's needed to do something
HIDDEN_APP: This again is a process, that sits idle (but still alive) in case it's needed by an app that's alive and running
CONTENT_PROVIDER: This is apps that provide data (content) to the system. HTC Facebook Sync? That's a CONTENT_PROVIDER. So are things like the Android Market, or Fring. If they are alive, they can refresh and provide the content they are supposed to at the set interval. If you kill them, they can't of course.
EMPTY_APP: I call these "ghosts." They are apps that you have opened, but are done with them. Android uses a unique style of handling memory management. When an activity is ended, instead of killing it off Android keeps the application in memory so that opening them again is a faster process. Theses "ghost" apps use no battery or CPU time, they just fill RAM that would be otherwise empty. When this memory is needed by a different application or process, the RAM is flushed and made available for the new app. To satisfy the geekier people (like myself) Android does this by keeping a list of recently used apps, with the oldest apps in the list given the lowest priority -- they are killed first if RAM is needed elsewhere. This is a perfect way to handle 'ghost' processes, so there's no need to touch this part

i said it numerous times... android is NOT windows. your free ram in linux => your system fails to work. your free ram in windows => you can open up more programs until the ram is full.
in linux it is better to have the whole ram full, not free. if you want more infos, you can search on the net.
When an Android app is no longer in use, the system will automatically suspend it in memory - while the app is still technically "open," suspended apps consume no resources (e.g. battery power or processing power) and sit idly in the background until needed again. This has the dual benefit of increasing the general responsiveness of Android devices, since apps don't need to be closed and reopened from scratch each time, but also ensuring background apps don't waste power needlessly

Android manages the apps stored in memory automatically: when memory is low, the system will begin killing apps and processes that have been inactive for a while, in reverse order since they were last used (i.e. oldest first). This process is designed to be invisible to the user, such that users do not need to manage memory or the killing of apps themselves.[65] However, confusion over Android memory management has resulted in third-party task killers becoming popular on the Google Play store; these third-party task killers are generally regarded as doing more harm than good.

i said it numerous times... android is NOT windows. your free ram in linux => your system fails to work. your free ram in windows => you can open up more programs until the ram is full.
in linux it is better to have the whole ram full, not free. if you want more infos, you can search on the net.

wrong. they remain in memory but they will not consume anything. that's what cache memory means.

Much more then just auto start managers..enjoy

High RAM usage?

I've noticed on my e975 EU version even with 0-1 apps open the ram free is only 1gb... Other phones have far more ram available including my previous nexus 4. Anyone else notice this? I often find with quite a few apps open I only have 2-300mb free

I've never seen less than 500mb free but its true. Never more than 1gb.

I checked earlier with 0 apps running it was at almost 1gb used.. what on earth is using almost 1gb!? If phones with only 1gb can use less than that on jelly bean.. why does this phone use so much?

According to ram usage i am using approx 400mb, task manager says im using 800mb. Maybe 400mb is reserved for system? This is on stock rom with only a few apps installed.
Keep in mind free ram is wasted ram. Free ram is like having a fast car and only using first gear. Still curious to know where it all ram is used nontheless.

I get what your saying with 'Free ram is wasted ram' but when you run out of ram.... things will start to stutter.
Having a few apps open to find you only have like 300mb left is insane.
I've had phones with only 1gb ram before and with lots of apps open they are using like 700mb/1000mb... it's almost like this phone is going 'Oh I have 2gb available so i'm just going to chomp up 1gb for the sake of it and leave you with 1gb left....'

If you're root use an app called "Greenify". Simply hibernate the apps that don't use adding to the list of the app, then add the widget to hibernate the app that you added (all except whatsapp, twitter in my case). In addition I use a tasker manager (don't added to greenify) and add a widget too, that combination gave me 1,2 gb free using a lot of widgets

Im stock un-rooted.
I only have 2 widgets on my home screens, 1 is the standard world clock and the other is play music. Tried removing both and it barely made a dent...

That's weird, only 900 mb free?? Mmmm, try using advanced task manager from the play store (I don't remember if root is needed), that will free you more memory. But in the 900 doesn't mean that the phone will be heavier, backward the used ram is exploited to make the Optimus lighter

Seems odd eh...

I also have 600 - 700 MB of RAM when I do not use anything.
There are just icons on my homepage, and a calendar widget (stock one).
At this case, It gives me 600-700 MB of free RAM. I always use "clear RAM" button. But why it gives us so limited free ram?
I used to use 4X HD with 1GB of RAM. There were 350-400 MB free which almost same with this optimus g?
Can someone explain this situation?
Or I think we need a new update. or CM10.1

It just feels like the phone is using up too much or isn't optimised properly.
As said above, phones with only 1gb available use about 3-500mb... Our phone with 2gb available seems to use about 900mb-1gb with nothing running. It's like it's gone 'Oh there's twice as much free so I'll just use twice as much...'

What about the AOSP custom Roms ...is the ram usage is same on that kind of Roms too?

No clue, i'm 100% stock unrooted Maybe someone will know.
My nexus 4 was far better at ram usage than my optimus g mind you. No matter what it never used more than 1.2gb

I think the Lg UI(stock firmware) is a memory hungry ...i suggest to try AOSP roms with lg skin :thumbup:

Using cm10.1 and have always about 1.4gb free, and this is more than enough for everything.

Y, stock rom have a crazy high ram usage, now im on PA and got 1.2gb free.

My doubt would be if, on stock rom, you get many slowdowns when you experience this high RAM usage. For me (who doesn't still have a LGOG, but is seriously thinking of buying one), it's the thing that matters most - if the lack of free RAM results in worse usage.
Otherwise, most efforts could do more harm than good - a task killer that kills an app which will restart seconds later is wasting RAM and battery instead of saving them.
I'd give priority to greenifying unruly apps you need often and freezing apps you rarely/never need but won't/can't uninstall (with Titanium Backup, or any other app that can freeze system apps) - always making sure you're not freezing some system app that will bring your phone to its knees. With this well configured, I'd say a task killer would only bennefit those of you that rarely use your phone. Everyone who often takes it out of their pocket and updates Facebook/Twitter or plays games should let Android take care of itself, as it will keep in memory the apps you've been using the most - as it should.

Don't use task killer apps, they aren't good for Android. Maybe something like a LMK Manager but you need root to change lmk.

M$ Windows does the same thing - if you have 2GB it uses only the half, if you have 8GB is use nearly 3,5-4GB. I think it preloads a few things including the most common used apps in memory perhaps?
