P.S. The Speed of your Computer probably effect the Speed of Syncing Music too.
Here is my Mac & iOS Set Up:
MacBook Pro 17', Late 2011, AntiGlare Screen
2.5 GHz Intel Core i7, 8 GB RAM, 500 GB SSD HD
Mac OS 10.8.5 Supplemental
iPhone 4S
64 GB - iOS 7.0.4
To play it safe, I am plugging my iPhone 4S directly into my MacBook Pro, unlike in the past, under iOS 6.1.3, where I used to plug it into Thunderbolt Display and never worry about it.
I have Re-Installed my iTunes, Version 11.1.4, and that didn't help!
To say that it's only iOS 7 that is causing this Slow Sync might not be totally fair. It's how iOS is "co-operating" with iTunes, and maybe with Mac OS itself!
I wish I had another iPhone 4S, just like mine, 64 GB, but running the Previous iOS 6.1.3. Then it would be possible to Isolate this Slow Sync Problem to just iOS 7.
Another "Suspect" could have been this:
I had a Particular Podcast in my iTunes on Mac, and it was Syncing to 2 Occurrences of that very Podcast on both my iPhone 4S (running iOS 7.0.4) and iPad 3 ( running iOS 6.1.3). It is possible that there was a "Confusion" somewhere in the iCloud Sync part of my Entire iOS Sync, where as the iCloud could decided which of the 2 Occurrences of the same Podcast on my iOS Devices to Sync with?
So I Deleted that Podcast from my iTunes and on iOS Devices, and then Re-Subscribed to it again! That seems to have helped! But only Time will tell if THAT alone was The Cause of my Sync "House Of Cards" Falling Apart, or if it was one of several other reasons for my Sync Instability! What I can say for sure is this:
After I Deleted every instance of that Podcast and Re-Subscribed to it, I did not see any Improvement in the Sync Speed! That Speed became Slower as the Number of Songs already Synced to my iPhone 4S Increased! The Greater Number of Songs on my iPhone 4S, the Slower the Sync!
So, with all those Time Estimates Formulas, at least you will have Some Predictability before you start your Sync and go to bed!
When Apple finally fixes this Slow Sync Issue, I'd be able to add Songs, or Text To Speech Articles ANYTIME to my iPhone! After 1-4 Minutes Sync I'd be able to Go Out and Have a Life, instead of starring at iTunes, and not even know when it will say:
• Waiting for changes to be applied
• Waiting for items to copy
And iTunes is NOT Telling me How Long it will take BEFORE for the Entire Sync to Finishe before I Click on Sync or Apply Button!!! Seeing such Estimate would have been very helpful!!!!
It would also be great if Apple allowed us to Pause in the Middle of the Sync and Resume it Later, when we have more Time!!!! But right now, one can either Eject iPhone, or Disconnect it, or Cancel the Sync!
Disconnect is NOT a Pause! It creates a Corruption, where the Other Space Size in iTunes Status Bar can icrease several times, or Disappeare completely! Eventually, after Re-Syncing, that Other Space might get corrrected or not! If not, the only other way to fix it is to do Yet Another Restore As New, then Restore from Backup! That means another bunch of Overnight Syncs, basincally starting from the begnning!
Cancel Sync = Undo that Entire Sync, and possibly More! Then it's like doingYet Another Restore As New, then Restore from Backup! That means another bunch of Overnight Syncs, basincally starting from the begnning!
Another Suggestion - it'd be great if the iOS Sync is having a Problem with iTunes Library, it would be great if there was a Log, so that we could See The Errors, with Suggested Fixes!
I have already provided some of this Feedback via http://www.apple.com/feedback/iphone.html
Adding to the FRUSTRATION on that Feedback Page is the fact that I had to Split this Previous Feedback into 6 Parts, because there is a Number Of Characters Limits on the Comments Field at http://www.apple.com/feedback/iphone.html
According to http://www.lettercount.com it's 782 Characters, which is not as bad as 140 Characters Limit in Twitter…
It would be GREAT, if Apple Feedback had a LIVE UPDATE CHARACTER COUNTER, so that a Person Posting would know how close to the Character Limit they are!!!! Hey, if Twitter knows how to do Count Characters, then we should expect no less from Apple, right:)?!
Other than this Sad Issue with this Slow Music Sync to iOS Devices - I LOVE Apple, and I can't wait for them to Fix this finally!!!
