IPhone – I lost 2.3 GB after unjailbreak the iPhone 4s

iphonejailbreak

I just unjailbreak my iPhone 4s to the original 5.1.1 version.
I notice the devise is now SUPER slow and also I noticed that the storqage capacity lost 2.3 GB !!

I have 16 GB iPhone 4s and iTune showing [Capacity 13.62 (.31 other) (13.4 free)]

The way I jaibreaked my iPhone is by
– downloading 5.1.1 from iTune
– enter the DFU mode, (power button and home button for 10 sec then only home button for 8 sec)
– click restore

How can I unjailbreak my devise in the correct way? (if I did it wrongly)
What is the reason for losing the storage?
