[Q] Free memory for the apps

Hi,
I'm considering about IS purchase but wonder how much free internal memory does this phone have for user apps after the first power on? Original Desire's free memory for the user apps was total crap, how is the situation with IS? Thanks.

Are you saying that there was 1.1GB FREE internal memory for the additional apps installations? Am I right?

Yes that is correct. There is 1.1GB free internal memory for apps.

What Is The Free Ram In this HTC ...? Can it has more than 350 MB free just like GALAXY S........ i think Galaxy is the Best Phone till date..... it can also Challange Tegra2 Processors Handsets....

[Q] SD Card Upgrade

I'm looking forward into upgrading my SD Card, right now it's the default CLASS 2 with 2gb. I pretend to buy a 16gb class 10 one, from Adata.
But I need to know some things first. The only reasons that I want to upgrade is to get more space to install apps, place musics and maybe expand my RAM a little.
So, is it possible to expand my ram? I don't want performance upgrade, it's just that I tend to multitask a lot of programs and my memory runs out really fast.
If so, how much more memory I can allocate on my SD?
Same for apps.
How much big can my apps partition be?
I saw that the recommended limit is something around 1.2/1.3gb, but is there a safe way to expand a little bit further? Or would it make the phone too much unstable?
And also, is it really worth it to upgrade my SD to a CLASS 10 one with 16gb? Or is it just a waste of money?
Thanks for the support and excuse me if I'm asking on the wrong section/way. I found somethings about it but there was nothing too much concrete. :/
EDIT
I just flashed my X8 with the latest firmware and baseband, as pc companion didn't want to install the baseband ..15 nor the newest drivers. Also installed the CM7, dualtouch and all that crap. It already installs apps to the SD and I've noticed a small slowdown on app startup. Would a class 10 sd soft it out?

Up to 200MB on SWAP partition, up to 2GB on apps EXT3/4 (any1 have so many of them???) rest for music/videos etc.

I have made a guide for partitioning the SD with ext+swap (you need AlfsKernel+GDX)
Look my signature

Thanks. But just another question. Is it really necessary to have a Class 10 SD card, or would Class 2 (the default one) slow things down while using swap?
Edit:
Also, a class 10 sd card is way too much expensive for me. I found a 16gb one, class 4 but it's SDHC. Will my X8 read a SDHC?

Everything above (and including) 4GB is sdhc, so yes, it reads them fine. About speed, yes it's important, apps will load faster.. but never amazingly fast. The X8 is slow nowadays, don't expect awesome results. If you are used to class 2 speeds and you buy a class 10 card then yes, you will notice improvement.. Not that much with a class 4. Do you really need a 16GB card? Maybe a 8GB class 8 or 10 would be better if you don't need that much space.
About adding more ram, just forget it
Sent from my E15i using XDA App

I got almost 20gb of just music on my computer, full discography of bands and all. Basically, 90% of the sd will be dedicated to music then But maybe i buy a 8gb one, i just need to stop being lazy and copy only the musics that i want instead of CTRL+A, CTRL+C, CTRL+V it all. Thanks for the help by the way.

So class 6 sdcard is enough for x8?

No problem The thing is, we have a certain amount of RAM at our disposal, plus our devices are getting faster and faster, getting more and more cores, but not that much RAM increase.
Let me illustrate my point :
htc HD2 (my frist device to run Android) - 2009
RAM : 448 MB usable
CPU : 1 GHz Qualcomm Snapdragon (single core)
SGS3 - 2012
RAM : 778 MB usable
CPU : 1.4 GHz quad-core Cortex-A9
So CPU speed is up by way much more than RAM, and I'm not taking GPU into consideration, plus storage speed increase etc...
Now those devices tend to be used in multitasking, having many apps running at the same time.
What those need is :
- CPU power to run on (we have plenty !)
- RAM to fit in (we have little)
Now even though an APP is running, not every bit of it is really needed, so those parts can be swapped out (put into swap) freeing these memory blocks and making room for more apps to fit in RAM.
So what will this mod do for you : Allow for more multitasking
Keep more apps running in RAM at the same time, making the device snappier when switching from one app to the other.
One app won't run faster !
If now you don't have swap, Android will have to gently ask the least used app to please close (save data, and quit) to free up RAM. Now when you get back to that app, Android will have to reload it, the app will start and reload it's data.
You can see, this will take more time.
Hope this isn't too confusing

I have a question before i attempt setting this up.
How do we identify which partition on the card is supposed to be for swap?
I have a 64gb sandisk card and say i make two partitions, one massive one for data and a 2gb one on the end for swap, how do i identify to android that the 2gb one is for swap? Also, what format should the partition be?
Cheers.

The script handles finding the partition
All you need to do is partition your card and be sure the swap partition is :
- a primary partition
- of type "Linux Swap"

Yes, just create one partition with the size of the card, and make it a primary partition of type "Linux Swap".
But just a thought, what speed class is this card ? A too slow card might not be a good idea to use as swap device.
I'm waiting for my 64Gb card, so for now I'm running 512Mb swap on my older Transcend class 4 card, which is running fine for far. I'd not really go lower, though it's sur worth a try
JP.

Will the whole swap partition be used as swap memory?
And one more thing: what happens, if you remove the external sd, while the mod is active?

There's no mention what class it is. As i remember card came with some nokia phone 2-3 yerars ago, so i think that it's pretty slow, but i will test it anyway.

use with extsd and internal sd swap script?
Hi,
just wonder if I can use this with the extsd and interenal sd swap mod by mattiadj?
that will be great if i can use both mod and if we can use both, where will be the swap space? still the extsd?
thanks.

Hi,
Thank you for sharing this mod. What size would you recommend for the swap partition? I think that the general recommendation for desktop Linux is something like one to two times the size of physical RAM, depending on available disk space. Would that be reasonable for Android as well?

Swap will all be used, but they will have a priority (order) which you can check by typing "cat /proc/swaps" in a terminal.
I'd not use many though, you don't really need that much swap Just compare and keep whatever works best for you

On Android that might be shooting a little too high. I have a 512Mb partition, but I suppose 256Mb would be fine, that is the size I used on my previous devices.

For me Ramexpander say is not compatible with Ace.

I heard swapping partition from sd card to increase the ram, sd card might get damaged!!, is it true?

Reduces SD Life so yes.
Sent from my iPhone

but i guess you will change your sd card before it gets damaged so much, that you will notice.
i only had this once on a USB pendrive. it loses data since some weeks ago. but its about 8 years old.
lets say that todays SD cards have better lifetime than years old USB sticks. lets also say that you use your sd card more often than i used this stick (backups later car-radio). so we can say your SD card might have a bit less lifetime. lets say 6 years. in 6 years you will (most likely) have a new phone, sd cards are "oldies" and if not, 1TB cards are state-of-the-art.
so....yes you loose lifetime but i dont think you will use it till it "dies"

It really depends on use. When I swapped i ate through my sdcard in less than 6 months.. so there you go. Keeping low swappinness will increase sd card life, but it does depend on use.

increasing ram by swapping sd card is effective to what extent...can any body tell me....does it bridge the gap of our low ram...

That why the requirement need class 10 SDcard

You can use CM7 that uses less RAM!.. I just went from CM10 to CM7 and it really is an improvement for ACE as it uses a bit less RAM and that is noticeable.

thanx but no cm7

there are quite a few apps for increasing the ram like ramexpander and swapper...
but before using these apps remember that the read and write speed of sd card(which is secondary storage) is vey less as compared to that of the internal ram.. and probably thats why ram is very expensive as compared to sd card...
so if you use these apps may take a bit longer to start and even the best of sd cards i.e. the class 10 one won't last longer than 6 months...

Increasing ram
Hi i install ram manager pro apk on gts5830i then i create a swap file 128mb using this apk, then on sd card i see swap file img does it mean my phone ram increased.... i didn't install any kernel for it... plz does tell me if it increase ram or not...

I tried something on a other phone from my neighbor. is a huawei with same specs than the galaxy ace..
I moved apps to SD card with link2SD and created a Swap file in the internal storage.
The internal storage is much faster than the SD card and much better for swap file.

What is RAM
Random Access Memory (RAM) is temporary data storage that the CPU uses during calculations. The more RAM a device has, the more calculated results the CPU can store - which means less time the CPU has to do the same thing over and over again. In other words, the CPU can check RAM to see if it has already made a particular calculation in the recent past. If it has, it can use the pre-computed results instead of wasting processing time recomputing the same calculation. In short, more RAM means a more efficient (and faster) device.
SWAP
What is SWAP
Swap is, in short, virtual RAM. With swap, a small portion of the hard drive is set aside and used like RAM. The computer will attempt to keep as much information as possible in RAM until the RAM is full. At that point, the computer will begin moving inactive blocks of memory (called pages) to the hard disk, freeing up RAM for active processes. If one of the pages on the hard disk needs to be accessed again, it will be moved back into RAM, and a different inactive page in RAM will be moved onto the hard disk ('swapped'). The trade off is disks and SD cards are considerably slower than physical RAM, so when something needs to be swapped, there is a noticeable performance hit.
Unlike traditional swap, Android's Memory Manager kills inactive processes to free up memory. Android signals to the process, then the process will usually write out a small bit of specific information about its state (for example, Google Maps may write out the map view coordinates; Browser might write the URL of the page being viewed) and then the process exits. When you next access that application, it is restarted: the application is loaded from storage, and retrieves the state information that it saved when it last closed. In some applications, this makes it seem as if the application never closed at all. This is not much different from traditional swap, except that Android apps are specially programed to write out very specific information, making Android's Memory Manager more efficient that swap.

[Q] Repartition to increase RAM - Nook HD+ Rooted?

I am running CM 10.1 internal rooted on a Nook HD+. Is there any way to increase the RAM or expand its partition? I'm OK with the internal storage for apps, but I'd love to allocate more of it to RAM in hopes of speeding up the tablet a bit. Any suggestions or guidance is welcome. Thanks! PR

Some major confusion is going on here.
EMMC is not really RAM so you cannot reallocate storage between the two.

When I go into 'Apps' under 'Settings' and look at what is running, it shows me how much available memory is being consumed. RAM, I guess, is not the right term for that. Anyway, I've got roughly 769MB available of memory for running applications. With what I have installed right at this moment, 616MB is used, and 163MB is free. What I'm looking for is a way to increase the total available beyond 769MB. Can I re-purpose any of the internal storage to be used by running programs? Does that help clarify what I'm asking? Sorry for the confusion.

I think you are trying to ask the question I have just asked on 10.1 for dummies, the device has 1024mb ram but cm only shows it as having 768mb? Further more as very green states, emmc and ram are two different things, ram isn' partitioned as you have suggested.

Some portion of Nook's memory (RAM) is allocated to system use, as is some portion of Nook's internal storage (eMMC or flash memory). Both are distinct from each other, and apply for all computing devices. The difference is in how the numbers are reported--total amount or available amount. Available RAM can't be increased.

The current Nook HD+ has only 1GB RAM only. If you want to increase the RAM you can use a third party app to do just that. Currently I'm using ROEHSOFT RAM Expander (SWAP) https://play.google.com/store/apps/details?id=com.swapit.expander.de. I could increase my RAM to 2GB for right now using the space available on my external SDCard.

That's bound to be super slow.
You can have better luck by using zram which is a standardfeature of CM, for example. Works by creating a compressed swap image in RAM, so should be faster than sdcard-based swap, but still slower than real RAM.

The problem with ZRAM though is it consumes CPU cycles. It's a chunk of RAM that is compressed like a zip file on the fly. It may just make your Nook slower and probably impact battery life to some degree due to increased CPU load.

It's not like emmc access is fast. And compared to swap on emmc, compressing to RAM is probably super-fast
