different usage shown on phone and on computer
my iTunes show that i have 5.18GB free space, but on my phone it shows 3GB. I've tried restarting, syncing, but it's still different.
iPhone 5s, iOS 8.4
I have this same issue. At the moment, my iPhone tells me it has 1.3GB free, while iTunes thinks it has 2.65GB free.
Worryingly and rather annoyingly, a quick search indicates this has been a problem since at least 2010 - iTunes 10 - incorrect ipod/iphone free space calculation
