My iPhone 5 won't update to ios 8.4.1: Not enough space
The Error says I need 610 MB of space, but my phone has 2.4 GB free.
Trying to update via iTunes on Mac Book Pro
iPhone 5, iOS 8.4
Do you see that huge amount of Other data on the screen? I think that is why you are getting this message. Read this.
Another good article on the Other and options to decrease its size:

I'll look to reduce "other", but why does this error happen when it appears I have plenty of space?
I know that you addressed your question to Demo and he will invariably reply. My two cents... The space reported by your phone is the accurate amount, the space reported by iTunes is an estimate and often varies, particularly when it has been a while between syncs. iTunes unfortunately "believes" its own estimate thus is unable to complete. Your phone very likely has a corrupted Other and about the only way to correct that is to do a Restore. Here is how:
Use iTunes to restore your iPhone, iPad, or iPod to factory settings - Apple Support
Also for what ever it is worth, I "Restored" both my iPad and iPhone in the last two weeks. I do that on occasion not only to reduce Other (it drops to about 200-300 MBs) but also to install a fresh copy of the iOS. Have never lost any data or settings.... other than one free app iTunes could not find but was indeed in the store, an easy re-download (iTunes warned me about this). iTunes is really superb, it will guide you through the process rather easily and of course you have folks in here that can step in as well. Good luck.
Ah thanks. you're right. Phone showed only ~200 MB free. itunes was quite a ways off. Thanks.
Please note my edit to my post.... 🙂
No need for my 2¢ other than I agree with elcpu.
