Did you figure this out yet? I was wondering the same thing... When I was researching the 2 phones, I saw they had the same amount of memory...

 

I would really like to know the answer to this so if you find out will you post it? Thanks

 

The standard apps that come with the phone I'm sure take up some of the memory. Maybe the phone only shows available memory left over after factory apps installed.

 

SIGH....

Who EVER said it had 256mb of memory for apps? Nobody did you just made that up on your own.

Eris has 512mb flash and 288mb RAM

the 159mb of flash is whats left over from the 512mb of flash used to store the OS.

288mb of RAM is just that, 288mb of ram, you cant install and store apps in RAM it does not work like that.

I would recommend learning how computers work.

 

i wont fault you for this one

 

The system including linux applications/libraries, default htc applications, android framework, ringtones, and other sounds comes to about 150MB. That does not include the linux OS. This was just the system directory. The HTC apps come to about 67MB of that. HTC has replaced pretty much every stock android application with their own more advanced version.

Once the device is rooted (note that the eris has not been rooted yet) you can put your apps on the SD card and the internal memory is just for the ROM.

 

There is nothing left to not understand we have just gone over this already.

The OS/System with all its parts allocate 353mb of the 512mb flash memory. You are left with 159mb.

512mb - 159mb = 353mb. Simple 1st grade math.

This is not that diffcult to understand. 353mb is allocated for OS/System use ONLY.

There probably IS memory from the 353mb not being used right now but its still reserved for OS/System use only since the Eris is getting Android 2.0 which is going to be a larger OS.

The 353mb memory is NOT for YOU to use. Its for HTC and future updates ect.

 

I'm wondering how noles managed to switch back to the Droid. The Verizon people told me you can only swap once in your 30 days. Droid>Eris>Droid = 2 swaps.

 

Another memory related question: With all my apps, my Eris is saying I have only 39mb of internal phone left (in the SD card and phone storage menu in settings.) Does this little amount of memory cause performance issues? Or is this just storage for apps and performance is only tied to RAM. I'll start dumping apps that I don't use if this causes performance issues--which I haven't noticed. The phone seems to run well still...Thanks in advance for any clarification!

 

When I bought my htc they sould me an extra card (not sure if this is the correct language) for 2 gb. When I looked at the one in the phone it is a 8 gb. Does that mean there is plenty area for storage but not enough memory to run everything?

This is my take on this. The eris is a faster computer than my first 386 clone and apple2and running on 4.5 floppy drive with only a few kb of ram.

All computers store data in hard drive in eris it's the internal memory. If you think you are running out of storage, you can create a folder to move application to an external storage the 8 Gg of memory. I have not tried it yet to see if it is possible, but if it is not, I am sure HT or another developer will figure out a way of doing it with out rooting it.

Ram is used to run application and it only stores it there temporarily, then they dump it one your done with the app. So what ever alloted ram is given to you should be more than sufficient unless you run all your apps at the same time and or running in the background. You'll need a task killer for that.

Please correct me if it wrong. I'm kind of rusty now, my 1, 0, days are long gone.

 

That makes perfect sense to me. Thanks for the reply.

 

It's a security thing. The Eris has RAM, ROM, and the SD Card. The SD card can not be used to store applications. Applications can store data on the card but the OS is locked down so that it will only run applications that are in the Rom. That is why we must install the apps.

RAM: 288 MB -- Memory space the OS/Apps run in
ROM: 512 MB -- Memory space the OS/Apps reside in (Read Only)
SD CARD: 8GB -- Memory for application use, media, and other file storage (read and write)

The only way around this is to root the phone which has not been done on the eris yet.

 

so this whole internal memory thing is not something to get concerned about in the future? also -- what exactly is "rooting" ? (sorry if this is a stupid question)

thanks

 

The small internal memory is a problem IMO. I have about 15 apps installed on my phone right now and I'm down to only 91MB of internal memory left. Basically I'm limited to how many applications I can have. I believe, but not sure, that all android phones have this limitation in one way or another. Some phones actually have less ROM like the HTC Dream with only 256. The Motorola Droid also only has 512 MB so moving to the droid won't be any better.

The concern is that as the OS grows, and it will, the amount of space for the applications will decrease. But the phone is pretty flexible. If this were to happen there is a possibility that the app storage could be moved to the external SD card.

Rooting is basically becoming super user on the phone. Android is linux at the end of the day and the super user is named "root". Basically the exploits find a way to install a program called SU in the system bin directory on the phone. SU is a program that allows applications or users to temporarily become super user. Once you are super user you can do anything on the phone. Change configuration files, update the OS, change hidden settings, and many more dangerous activities.

 

sounds....dangerous... :x

 

it is First thing a person should do when the root the phone is change the root password. Many people forget to do this one task which opens the phone up to attack from outside.

 

Is there a way to tell how much memory each app consumes when it isn't running?

 

No there is not.

 

FWIW - for anyone who cares...

Here is how the 512 Mb of Flash in the Eris is partitioned (currently); you can see it for yourself in the system boot log ( get a shell running and run the command 'dmesg > /sdcard/dmesg.txt' )



[ 3.984344] Creating 6 MTD partitions on "msm_nand":
[ 3.984832] 0x1ff60000-0x20000000 : "misc"
[ 3.986358] 0x02c60000-0x03160000 : "recovery"
[ 3.987609] 0x03160000-0x033e0000 : "boot"
[ 3.988952] 0x033e0000-0x0dde0000 : "system"

[ 3.991668] 0x15fe0000-0x1ff60000 : "userdata"

From the point of view of progressive addresses, this looks like this:

Code (Text):

1.  
2. ????:      0x00000000-0x02c60000   44.375 Mb
3. recovery:  0x02c60000-0x03160000    5     Mb
4. boot:      0x03160000-0x033e0000    2.5   Mb
5. system:    0x033e0000-0x0dde0000  170     Mb
6. cache:     0x0dde0000-0x15fe0000  130     Mb
7. userdata:  0x15fe0000-0x1ff60000  159.5   Mb
8. misc:      0x1ff60000-0x20000000    0.625 Mb

during normal operation, only system, cache, and userdata are mounted as filesystems: the first is read-only, and the other two are mounted read-write. I don't know what is in the first 44 Mb.
