Android
mtmerrick:
If i remember how iOS shows stuff correctly, the system partition is hidden from you - you can't see how much space it takes up, but you should be able to get a rough guesstimate by subtracting the amount of user available space from the amount listed in the back of the device.
(note: this is logic drawing from a rough recollection. I may be completely wrong here, possibly)

I haven't ever seen a single device or component that had exactly as much storage space as it claimed having. Windows says my 64GB SSD has 59.6GB of space, my music player says that my 16GB MicroSD card actually has a total space of 14.976 GB, and my phone's internal storage reports 13.33GB available of the advertised 16GB. I think that only in the last case there is actually space being reserved for the system.
It seems that there is also a big chuck of space allocated to something that Android does not recognise, seeing how the storage report leaves about half of the used space unaccounted for, even in the 'Misc.' category. Those are most likely the full ROM backups I've been keeping, but I'm not sure.
I'm actually much more interested in where all of my RAM is going. Just like the storage space, it leaves some of the advertised 1GB RAM unaccounted for, only adding up to 694MB, but the running applications are only shown to take up half of that. I assume there are a number of unlisted background processes being used for the Android OS, but then those are taking up a whopping 345MB of the available RAM. Isn't that a bit excessive?

There's this thing that I hate about advertised storage sizes. The 64GB advertised is 64 Gigabytes (64 x10^3 bytes), but that also a tad over 59.6 Gibibytes (59.6 x2^30 bytes). I suppose technically they aren't wrong, since the Giga- prefix does mean x10^3, but computers will usually report the size in kibi-/Mebi-/Gibi- bytes with a label of kilo-/Mega-/Giga-.
Long story short, what you bought was indeed 64GB but I doubt that's what you thought you were buying. I've fallen in that hole before as well.
To make matters worse, I've sometimes seen RAM with kilo-/Mega-/Giga- prefixes meaning the 2-based value and storage devices using the same prefixes but actually meaning the 10-based value.

On storage space: It checks out perfectly.
I've had a little problem with excessive data usage over the past couple of weeks: 'Android OS' would show a constant background bandwidth use of about 100 MB a week, and users cannot restrict the background data use of this process. After some searching online, I figured out that it was related to Google backing up your phone data to its servers, and sure enough, when I disabled Google backup, the data use went back to normal. Now, I still had to figure out what application was using all this data, since I couldn't remember what I'd installed when the data use started going up. Before I could figure out how to read application folder metadata ('last modified' date), I came across another user on stackexchange who had the same problem, and one of the comments said "You aren't changing your wallpaper ten times a day or something, are you?" and the OP said "Yeah, I have Tasker set up to change my wallpaper according to my location, but it only changes two or three times every day."
Now everything falls into place. I'd also recently installed a wallpaper rotation application that changes my wallpaper every 6 hours, and every time that happened, Google would upload a new backup of it to its servers - without my knowledge. Those high-resolution wallpapers are about 4 MB each, and they would change 3 times a day. Multiply that by seven days and the total data use is... 84 MB per week. So that checks out too.
Unfortunately there's no way of telling Google not to back up my wallpaper - because why do I care about losing a picture that I pulled from the internet - and given how infuriatingly difficult it is to actually get in contact with Google about their services, I guess I'm sticking to a single wallpaper from now on.

...I've never had that problem o_O have you tried unchecking Sync Google Photos and Sync Picasa Web Albums?
