Does yourDesire Hd really have 768 RAM????

Sorry if this is a noob question, this is my first android phone and do not fully understand android of yet.
Basically going to settings >>> Applications >>> Running services.
At the bottom of that screen you see Other : a mb Available b mb + c mb in 46
I understand one is memory used by essential processes, available and memory which can be freed up but what i don't understand is why it does not add up 768? and only around 520 mb?

Some of you RAM is taken up by the HTC Fast Boot feature. Around 80~100MB is used.

in adb shell type free and it will show around 630MB available, the rest is used for Radio and GPU

so disabling fastboot is advised?

Why? Do you really need the 768MB of RAM? What are you running? Photoshop? 768MB RAM is enough for a loooong time!

It's not a question of needing, I was just enlarging my knowledge on the subject.

Theoretically, it is possible. Try it out and see what happens and report back. However, it is also possible that the device saves some ram for hardware acceleration/graphics memory like the HD2 did...

[Q] Ram doesn't add up? (Not the usual question)

Hello,
So I just recently got my Nexus, and I'm really really loving it. I had a question about the RAM. I'm on stock un-rooted and I noticed I had a little less that 700 MB ram. I know that's for system or gpu or whatever so I'm ok with that.
What I'm confused about is, I'm currently using 400 MB of it. If I combine the totals from the "Running Apps" section plus what is in the "Cached" section, it doesn't come close to the total 400MB being used.
So where is the extra Ram being used from? How can I free some of it up?
I've been reading that task managers are a no-no for ICS, so I'm more curious about which apps are killing my ram.
Thanks in advance

Killing it how? Using it to make you phone react faster?

Well sure in theory make the phone run faster. I imagine having more free ram available to be used in the cached application section and not the "running application section" will help make apps load quicker too. My friend had a desire and the amount of ram she had did drastically effect her phone performance.
But also because I'm curious about where is that extra 200 or so MB of ram is being used from?

Linux shares ram within apps/processes in a very complex way where even the experts have difficulty explaining exact tallies on ram levels. This is why different apps report different free ram values like os monitor vs system panel vs stock settings etc. So i wouldnt wprry about how android OS shows your ram value in settings, its not gonna add up and its a tricky question to ask.

Hmm alright. So basically it's not something I should worry about? It's quite a large discrepancy. I guess I'll worry about it once I have errors that are "low ram" or something to that effect.
Thanks anyway

It's the discussion like there was in the galaxy s forum. The not displayed ram is used by the kernel it self and by the GPU. And besides it's a good thing to have a full ram in Android, because then many apps are pre loaded in the ram and can start faster this way.

Its always been like this on my android phones, i wouldnt worry. For example if you kill all current apps, you wont see free ram increase at the exact level of the total of all closed apps. Too much overlap and ram page sharing i think.

Don't worry about it. Some ROMs e. the stock ROM, don't have a seperate RAMDisk.
So, basicly, the ROM dumps some cached processes on to the RAM directly "clogging" it. If you however, have a custom ROM, eg. CynagonMod, the system uses half of the RAM it would use as a stock ROM, because cm uses a RAMDisk, which uses a minimal amount of space, on the device's memory.
But, there's absolutley nothing to worry about
Enjoy the phone and leave the RAM, as it is

Can anyone here tell me how to partition my sd card to create 1 ext4 partition to increase internal memry, 1 simple fat partition for daily use, and most importantly gto create 1 swap partition to increase my RAM and how to use it as RAM in galaxy fit ... Plz provide me a tutorial

The Galaxy Nexus doesn't have an SDcard. You can't partition it up like that.
Also, think you're in the wrong forum.

[Q] Samsung Galaxy Note 10.1 2014 Edition uses Too Much Ram

Hello there
I have just bought a Samsung Galaxy Note 10.1 2014 tablet. But it consumes too much ram.
This causes instability and excessive battery usage.
Do I have any chance about this?
Thanks

Android isn't compareable to windows in ram usage. Your tab will run smoother if 1gig is used instead of 600mb, because some data is still in the memory which means faster app starts...
If android needs more ram it cleans the memory itself

Then it's something you installed, because out of the box it's fine.

How did you make that connection?
There are multiple posts here about RAM usage on this tablet and many more about RAM usage in Android. You don't need to worry about your RAM, OS does a good job managing it.

Hi again
I Use "Clean Master" to montior my RAM usage and it always shows ram usage is around 92%
I didn't install too much stuff. A couple of games which I play rarely and a few drawing apps.

IMHO a memory monitor could mess up with normal memory management, because if it is set to a too restrictive policy it could try to free memory that OS will reuse at once, and so on.
I would suggest trying to use your tablet without the memory monitor, then compare the behavior.

How does used ram cause battery drain? It does not. What causes battery drain is when your cpu is getting used. When your apps aren't precached your cpu will have to work a bit harder every time you start an app. Also your memory monitoring app will use more cpu cycles than it will save you. What you could look out for are apps that consume lots of cpu power. Sometimes apps are badly coded and consume lots of power. Those kinds of apps will most likely show up in the battery stats in the settings menu. No external apps are needed. They usually cause more harm then good.

Yes maybe you are right. I managed to improved battery life. But I can't say the same for RAM usage.
Compared to my Sony Xperia Z1, Samsung Galaxy Note 10.1 2014 responds real slow. Although it has more RAM. (2GB vs 3 GB)
I did a research about speeding up it. But couldn't come up with a sollution.

More ram doesn't really make a device faster. Nowadays it's a lot more about the software and drivers etc.. Samsung sometimes neglects that and focuses on adding software stuff that they can advertise. I wrote a guide on speeding the device up. It assumes you have root, but you can just see how many apps you can disable in the settings. Might be enough.
After applying all the steps and keeping my device clean it's the fastest tablet I ever had in my hands.

More ram usage is a sign of more services running.... which means there is loads of stuff running in your background..
If I dont run a single app my ram has 1.3 Gig ram left... go to application manager and check whats running... if you see stuff you dont need freeze it with titanium backup.. or unistall if you are sure its not needed.. your system does not simply use more ram randomly...

RAM is there to be used. Free RAM is useless RAM. The more RAM it's using, the lower the battery usage because it doesn't have to go to flash memory for data.

Like he says when it comes to Linux the more ram in use the better.

I found the problem. It is TouchWiz.
After disabling it and installing a new launcher, Nova Prime, I have no ram and lag issues.
Yes I agree about ram thing but with a huge amount of ram usage multi-tasking is not efficent.

Been running Nova Prime with Lag for several months, still lags. Disable the card reduces the lag a bit. That though is not an option.

it has 2GB RAM... but it normally shows 1.4GB RAM using and about 400MB RAM free.... does it normal for this new tablet... plz bcoz i am new android system ....
(sorry for bad english)

Yes, it is normal.
Simply put, Android has complex - dynamic - ways of using and re-using RAM space.
As long as you don't see messages like "unable to start program", you're on the safe side.

Its normal. It doesn't benefit Android to have RAM free, and in fact its usually more efficient to have RAM as full as possible. This lets you quickly access commonly used apps, instead of stopping and starting them every time.
Also, be careful about using task killers for many of the same reasons. Freeing RAM has little benefit, but constantly killing and restarting tasks can actually impact performance, battery, or cause other issues.

Can you lower the ram usage?

Hi there,
I have the ZF2 with 4GB of ram. After a couple of days of usage, it seems impossible to lower the ram usage below 1.8GB even when I clear the cache of all apps.
However, when I restart the device, my ram usage is below 1GB.
I have uninstall or disabled every app I could without rooting. & I don't want to root now.
Nonetheless, I would like to keep the ram usage of my device as low as possible (2GB of ram use seems a lot to me, especially when I have one or two apps open)
Did you find a tricks or ways to keep 2gb or more ram free at all time ?
Thank you.

Simply, there is no clear way and those numbers are normal. The best memory management is with native linux, not yet available on zenfone 2.

What's the point of always having 2gb of free ram? RAM is completely useless if you aren't using it.

It's not a question of useful or useless. It's a question of is it possible and if yes, how.

Yes, keep the phone in deep sleep with all apps closed and disable everything in autostart , better yet, you can just power off the device
p.s: not even custom roms will run that low, I had cm12.1 with lg g3 3gb ram, I disabled basically everything and phone will still boot with at max 2gb free ram, maybe 2.2gb if you start killing launcher and sytem apps lol
4Gb ram with 2.2-3Gb free Ram is plenty for a cellphone. Its even plenty for a desktop unless you run hard core 3d games like crysis.
The lowest I have seen is 150Mb/1Gb usage with Nexus 7 v1 tablet yet it was hell slow. Note that the more Ram you have, the more the system will use it and cache in it. This will increase apps loading speed since they are directly loaded from Ram vs local storage.
I would love to have an app that lets you select what to cache in Ram, e.g. large high-resolution PDFs that take forever to open and load :crying: I have 300-800Mb PDFs that will take 1 min just to open.

Indeed, an option to decide what to cache would be great.
Can we expect less usage and caching with the 5.1 update or with a custom Rom?
