Missing 3Gb?

[sciteach]

I recently purchased a 16Gb 4S. When I connected to iTunes it shows that, before apps, other, etc. that I only have 13Gb available. Does iOS5 take up 3Gb?

My iPhone 4 16gb shows that it has 13.7 free before anything else with iOS 5 installed. Of course some may be different from others depending on how the memory formatted. May be a different brand of memory from the 4 to 4s but I wouldn't think that it would be that different. I also don't have siri though so that may be some of the difference as well.

This is normal.

That's kind of what I thought. Thanks!

the hard drive and flash memory industry has been scamming us for years. you always get less than the amount advertised. the actual calculation is 1024 kb to 1 mb and 1024 mb to 1gb and so on. but they generalize it by using 1000 to 1 so they end up giving us less. the difference get worse as you go up in capacity.

The main reason as to why I was so concerned is that this is my first Apple product and had never had to use iTunes. I have a lot of music in WMA format. When I imported this to iTunes it HAD to convert it to mp3. The issue is that a 2mb WMA file converts to an almost 6mb mp3 file; I basically am tripling the amount of space needed for the same quality of song.
