How much space does iOS 9 take once installed?

I've read a few times that the download size for iOS 9 is much smaller then for iOS 8 (1.3 GB vs. 4.6 GB). Is this only a matter of download size, or does the OS also take that much less space once installed? Does anyone know if the App Thinning techniques (including only device-specific assets and binaries) has been applied to the OS itself as well?

The only thing Apple claims is that the space needed for updates is much smaller:

True, but I wonder why they don't take the step of applying their own App Thinning principles to the OS itself.. Should be able to shave off at least 1GB. Seems like a logical next step to take, maybe they're waiting for the next version because of the additional complexity of doing this with an OS vs. with apps.

OS thinning is not easy, and reducing code scale often means function reduction.
If they really want to reduce the install base, and optimise the whole system to a new level, they should re-write everything they have now, using a new optimised language. OK, this is only my thought.
Since iOS 9 is still in second beta, final result is still not so clear.

Apple should give people the option to delete unused languages similar to how you can delete then re download dictionaries! Also, iOS should be specific to each device and not install every devices artwork...

And this could dramatically increase the complexity.
Plus, deleting language packs doesn't save much of the space. It may cause some problems however, since November one can guarantee you would never touch another language. But, yes, maybe Apple can just retain a code page for multiple languages, while removing much of language contents from device.

Shrinking the build-in apps can help reducing the iOS size... and giving you the option for a free download if you need them down the road, or giving the option to delete them.

i got 7-8 build-in apps i would be glad to erase...

I also have several integrated apps pleased to remove if applicable. However, after checking clean Yosemite application folder, I know one thing: stock apps are in fact not so big as we thought. Therefore removing them would not help releasing spaces. Those big one preinstalled such as Keynote, would be delectable. And tell you what? I hope Microsoft office would be preinstalled on my device. :p

We talking about iOS on phones\tablets not OSX on macs... when im having limited space, 16GB in my case, every bit of space i can save counts ;)

Out of curiosity, since you checked how much the Stocks app use, maybe you can post its size in mb, as well as for other build-in app - health, Game Center, Newsstand, Tips, iBooks, Passbook, Podcasts... so we can calculate the total of free space we can have without them installed.

And what I have checked is stock app on Mac OS X, not iOS. My device cannot be jailbroken. I use Mac OS X as the example because since desktop version app doesn't count so much space, stock app on iOS should not occupy so much space as well.
If you post your question on jailbreak forum, I am sure you will get your answer. :p
