[Q] Memory Shown Less

Hello,
The RAM shown in my Nexus6 is
Code:
Total: 2970MB
Available 1332MB (45%)
Java Heap: 256MB
The Total RAM 2970MB is shown in the apps CPU-Z and Droid Info. Why the value is lesser than 3GB (3072MB) ? There should be a technical reason for that. Please let me know. Thanks.

Yep, the difference is allocated to a bunch of other hardware blocks, like the MODEM.

okay, I also have learned from the internet that the difference is held by the GPU, which the OS is not aware of. So the Total: 2970MB shows the available memory and not the installed memory, Correct ?

Yes. Boot to bootloader and it will will tell you what brand and size ram and memory is installed in device.

Also the storage space shows 54.6GB instead of 64GB. Is it because of the reserved space allocated, when the filesystem is formatted to ext4 ?

That is minus the system and other partitions reserved for firmware and the OS.

But it takes almost 10GB of space, which is huge. I think it is good that I have brought a 64GB version.

This is why you always buy as much memory as can afford.

If the remaining space (64GB - 54.6GB) is used by the OS and firmware, then what does the Available Storage mean ?
The Available Storage shows 49.88GB (91%). I mean there is one more difference: 54.6GB - 49.88GB. Please clarify. Thanks.

os and firmware + extra for future updates takes up the first 10 giving you 54. Available is your userdata. Anything less that 54 is what you put on it.

okay, When I brought this phone the Available Storage was 51GB, without adding any data by me. So I think something else has taken space from the 54GB (54 - 51 = 3GB).
Then I added some music files and the Available Storage is 49.88GB now.

Not 10 GB, no. The difference is less.
In software, 64 GB is 64x1024 Bytes x 1024 KB x 1024 MB.
In hardware, 64 GB is 64x1000 x 1000 x 1000.
Because there is now a difference in what hardware manufacturers call a GB, they tried to rename the true software GB to be GiB instead (though generally I refuse to do this).
So to work out how many GB of software data you can get in a 64 GB hardware disk, use the maths below.
64 x 1000 x 1000 x 1000, / 1024 /1024 /1024 = 59.6 GB
So a 64 GB anything is only really 59 GB.
Then as mentioned, that is partitioned into /system, /cache, /data etc

Okay, So is 'Total Internal Storage: 54.64 GB' the size of the /system partition or /data partition ?
Thanks.

/data AKA userdata. This is where your apps go, where your settings are stored and where your sdcard is.

So that 3 GB (54.64GB - 51GB) is used by the apps, I guess. So that is the reason why it was showing 'Available Storage: 51GB' at the beginning.
Thanks.

When you get the phone new, when you boot it, some system settings will be stored in data. Also some things related to Android Run time.

54.6 - 49.9 = 4.7
4.7 / 54.6 = 0.0861
0.0861 = 8.61%
8.61% rounded to the nearest percent = 9%
100 - 9 = 91.
Does that clarify it for you?

Worth buying a 2. hand SP for 100$? Possible to use 32 GB SdCard for installing apps?

I know that this phone is rather old currently but i'm still interested in it, let me explain.
I'm a Huawei Ideos X5 and Motorola Atrix 4G user, which are ancient comparing to XSP :laugh:. With the help of CM7.2 these devices are still operable. (Thanks to all developers and contributors). But i need at least Android v4.2 for some of the applications. These devices don't have official CM11, and unofficial CM11 Roms have some critical bugs and disadvantages for my usage, unfortunately.
I like Sony devices in general (do you remember K750i, W810i etc?) and interested in the compact series especially. I would get a Z3 compact but read a lot about the cracks and some other physical problems, so i decided to wait for the next generation. Then the Z5 Compact came at last, but with the notorious snapdragon 810! And it's still expensive, here in Turkey. So i think the next generation of Compact will probably be the ultimate one to buy.
Till that time, i want to use another compact sized phone such as XSP because it has these Pros among others:
+ Official Cyanogenmod support (It has stable CM11, and nightly CM12.1 AFAIK)
+ Gps with GLONASS support. (I use navigation in car frequently, so lock time and accuracy are important)
+ supports OTG AFAIK, although it's not noted on GSMArena page.
+ GYROSCOPE sensor.
+ FM Radio (is it still usable after installing CM11?)
Additionally, I'm aware of the Cons below, but they won't be a major problem for me (I guess):
- TFT display (it must be an awful joke )
- 155 gr weight
- 1 GB Ram
- 8 GB (5.8 GB user available) internal memory. (I have major concerns about these, see below!)
- insufficient Cameras
- Non-removable battery
- Low volume levels, especially in-call volume (This is a common Sony problem, right?)
Anyway, here come my questions:
* Does it worth buying a 2.5 year old second hand XSP for 100$? I don't know the brand new price, seems not sold nowadays. I didn't check the local shops yet, but buying a brand new one for a, say 200-250$, is not reasonable, right?
* Is it possible to use an external SdCard for installing apps? (By swapping external SDCard to internalSD, NOT via Folder Mount etc.)
I will definitely root the phone and install CM11 most probably. Please help me finding out these:
In general, the phones have /data partition for installing applications, and /sdcard partition for large application datas and user data. For example in Motorola Atrix 16 GB;
* /data partition is 2 GB .
It's large enough for me, so i don't have to move apps to sd. And some of the large apps install themselves to /Sd (be it internal 10,7 GB partition or external 32 GB in CM7.2) automatically. (The large games still need the /sd , that's for sure)
* /sdcard partition is 10,7 GB.
It's almost full although i use the other 32 GB SDcard for my music, video etc. files. Since CM7.2 has the option to use the external SDCard as internal SD, i can exchange them whenever i want. This is one of the most useful features of CM, i like it.
What is the situation in Xperia SP, can we use external SD Card to install apps?
The XSP has 8 GB (5.8 GB user available) internal memory, so i will have to use my 32 GB sdcard inevitably. And i have to use it as the main storage area for apps, not just for the user files! I guess it's not an option in Android JB and KK versions natively, right? What about CM11?
What is the content of the 5.8 GB user available memory? Is it
* just the 5.8 GB /sdcard partition (then /data partition is ?), or
* 1 GB /data partition + 4.8 GB /sdcard partition, or
* 1.5 GB /data partition + 4.3 GB /sdcard partition, or
* 2 GB /data partition + 3.8 GB /sdcard partition, or what?
I hope the /data partition is 2 GB or higher. Because we won't have to move the apps to Sd manually, if we have a lot of apps. And when we unmount the external SdCard for some reason, most of the apps are still usable, that's great. (I had to move some of the apps to SD in Motorola Atrix lately, because 2 GB is almost full! Another example, we had to extend the 600MB /data partition in Huawei Ideos X5 with a lot of hassle years ago. I hope i won't have to struggle like this in XSP!)
I will use the 32 GB Sd Card for the rest, apps' sd datas and my user files, anyway. Again, is it possible in CM11?
I know i asked a lot, but your opinions are really important for me. Please advise, thanks in advance.

Safestrap stock partition too small

Can you change the stock partition size on safestrap's stock slot at all? It shows two internal memory slots, one at 3.01gb and the other is 8gb. What is going on with that other 5gb and why isn't it used?

Not 100% sure, but I believe the non-user 8gb is split between /webtop, /cd, /preinstall, /system, /data, /cache/. /webtop and /preinstall alone eat up 2gb of it.
And, no, it can't be changed. Our resident awesome developer gave it a try a while back, and found that apparently the bootloader checks at power-on to see if the partitions are all "correct". If they're not, it pops an error screen, and there's nowhere to go from there; it pretty much soft-bricks the phone until the stock configuration is restored via fastboot image.
If we had an unlockable bootloader, then it's possible that this restriction could be removed. However, we don't - based on some poking at it by another member, it doesn't even recognize commands to pull information for/enter an unlock code - so we're stuck with stock partition sizes and virtual slots.
If you really have no choice but to use the stock "slot", you might want to look into buying a big SD card, getting Link2SD, and devoting part of said SD card to it. If you're using KitKat, the built-in App2SD might be adequate, but for Lollipop/Marshmallow, the 3gb just...isn't enough. App2SD isn't effective enough.
Otherwise, get a decent SD card and write the internal 8gb off as system storage. Make a slot with a 4gb /data size (the biggest we can go), and 700mb-1gb /system size. Install a gapps package that contains anything you would normally go to the Play Store and download separately; this installs them to /system, leaving /data more free for downloaded apps.
For large apps, use App2SD where you can to shift part of them from /data to the internal 8gb.
If you don't plan on flashing new nightlies very often, you can get apps to convert other apps into system apps, storing them in /system as well. The problem here is that they'll be wiped out whenever a new ROM is flashed, so you'd have to devise some method of backing them up and flashing them after the new nightly (ZipMe might work).

Nexus 6 32GB showing 29.12GB internally but laptop is showing 25GB

i installed lineage 14.1 it showed me that i had 29 GB space but when i connected my phone to laptop. my laptop showed me 25 GB. then i flashed stock rom again but still internally its showing that it has 29 GB but when i connect it with laptop its still showing 25 GB. i don't know whats going on. i have did lot of things. used adb/fastboot, twrp, FDR etc but nothing is working.
what am i missing?

There are different methods to calculate storage.
Megabyte is a unit equal to 1,048,576 bytes. The official SI definition is "mebibyte" MiB is 2^20 *bytes.

25GB is what you're left with after operating system. These files are hidden away to prevent people accidentally deleting them. What you're seeing is completely normal.
If memory serves me correctly, when you format the device it'll show 29GB in recovery, before the OS is installed.

you are not getting my point. it all happened after i flashed lineage OS. before lineage OS, everything was fine. after flashing lineage os, it showed me 29 GB but in real it was 25 GB in laptop when usb connected. and still now after flashing stock rom, this difference is not over. in settings there is 29 GB and in laptop its 25 GB

On my N6 (stock 7.1.1) it is the same. Storage 29,12 GB.
On the PC N6-storage is shown as Internal Shared Storage.
Capacity: 27.893.952.512.00 bytes = 25,9Gb.
Conclusion:
- I get your point.
- You are not the only one with 25,9Gb.
- It has nothing to with Lineage OS.
- It has to do with calculation, not with flashing.

I get 29.12GB on phone and when i hook it up to linux laptop it shows as 27.9GB. Running rooted stock 7.1.1.

That's the same as 27.893.952.512.00 bytes.
Also frequently used. But according to the Google marketing guys it's 32Gb.

It's not just Google. All device manufacturers do it. For example, a Galaxy S4 has 16GB storage, but after the ROM and recovery are installed a stock device only has a little over 9GB left. It's still advertised as having 16GB storage however.
The other issue here is that the hard drive manufacturers years ago redefined a gigabyte as 1,000,000 kilobytes while operating systems at the time used the original size of 1,024,576 kilobytes (now redefined as a "kibibyte"). The redefinition passed into common usage, so your 16GB (Gibibytes) is really 15.6GB (Gigabytes). Simply doing the math reveals this. 16,000,000 / 1,024,576 = 15.616. Confusing? Hell yes. We never had need of two systems. All the marketing geniuses had to do was be honest. But, being marketing geniuses, that was too much to ask for.

thanks a lot dear for understanding the situation. now i am feeling relax that this is not the issue with me only. but still, there is one question which keeps popping up in my mind is that when i received this handset it has the STOCK ROM 7.0 which was showing 25 GB in phone settings area and also showing the same storage 25 GB in the computer. if i look at that situation it looks normal to me. but now I and you are experiencing the same issue. why are we facing this issue now? is there any other way to flash the stock ROM to show the right storage space both on phone and on the computer because when i received the handset. its storage space was perfectly right on phone and computer and that was 25 GB.

54.6GB on Windows 10
58.24GB on Nexus 6
Flashing a stock ROM won't help here, as both numbers are correct. To resolve it so the Nexus 6 reports approximately the same amount as the PC, you'd need to revise the source code and change the storage space calculation so it uses 1,024,576 instead of 1,000,000. It may make sense in a zRAM app, and I did that modification for a zRAM app included in a custom ROM I was maintaining ages ago. However, I feel you're getting too hung up on the numbers here.

I've read about memory size issues. That concerned the 64Gb versions. Only 23Gb was shown/available. To solve this a reformat was needed.
I've used my N6 about 28 months. I have the idea that in all Android versions the user available memory size was always about 29Gb.
On my PC the size was different, but I ignored it.
N6 with Android 7.0 and storage size of 25Gb is weird for me. But Google delivered 7 versions of Nougat, so........ I can't tell more.

That's a whole different issue... That happens if you flash the data partition from a factory image. Since the image is made for a 32 GB system, it'll report as such until the data partition is formatted for the correct size, 64 GB.
The issue the OP is talking about is merely the difference between the prefixes kilo-/kibi-, mega-/mibi-, giga-/gibi- and so on.

Mi9T Pro 128 GB Internal storage capacity?

Quick question: Is the available storage space on MIUI12.5 109GB available? I can see two websites that list the Mi9T Pro as having 109GB of available storage space but just wanted to see whether this was the same for everyone else.
Reason being - I recently decided to update the newest MIUI12.5 version so the updater would stop nagging me and bumped into some MiFlash errors which I assume are due to quirks with MiFlash and USB3 (Xiaomi really needs to give MiFlash some work). Whilst my third attempt at flashing went smoothly start to finish with no errors I just noticed that 109GB is the available space with about 6GB used. The capacity of /root under Solid Explorer is 112.95GB.
My gut tells me everything is fine but that means MIUI consumers a LOT of space. I'd garner the overall eMMC is probably 117GB formatted and obviously that's not all going to be available for use but I just want to make sure I'm not missing any GBs. I'm guessing a successful MiFlash resets the storage chip anyway.
If anyone can check their partition sizes on stock MIUI and give me a general idea that everything is sized normally I'd be grateful!
If you're short on time, a thumbs up will do!
