Whispersync issue: Audible to Kindle on iOS

I upgraded a Kindle book by buying the Whispersync For Voice enabled Audible book. I did this through Audible’s matchmaker service.

The problem: Kindle will not update with the last location heard on the Audible app. The Kindle iOS and web apps will sync with each other, and Audible will always recognize the last position read in Kindle (iOS and web) and ask if I want to continue from that location.


  • iPhone 5, running iOS 9.3.4
  • iOS Audible app, version 2.14 (416)
  • Kindle for iPhone, version 5.1
  • Kindle web app (read.amazon.com)

Attempted solutions:

  • Delete and re-download book in both Audible and Kindle apps.
  • Delete and reinstall Kindle and Audible apps.  
  • Reboot phone. 
  • Manually hit the sync button in both Kindle and Audible.
  • In Amazon account, manually re-deliver book to Kindle app. 

Audible tech support suggested deleting/reinstalling the app and rebooting the phone.

The eventual (and accidental) solution: for unrelated reasons I restored my phone from a backup, which forced me to re-download the book. I was then having issues playing the book at all, so in desperation I changed the Audible setting for “Download by part” to Single-Part from Multi-Part, and downloaded the book again. 

Something I hadn’t seen before–when you change that setting to Multi-Part, a message pops up warning you that keeping audiobooks as a single file is better for syncing across devices. I do not remember seeing this when I originally changed it to Multi-Part. I also don’t know why I assumed at the time that Multi-Part must be better…probably because of the way Kindle books are broken up into locations.

don’t choose multi-part
Syncing now works both ways.

restoring an iPhone to create space removes data you probably want

I have an iPhone 5 that is perpetually hovering near capacity. I came across a tutorial online suggesting backing up then restoring your iPhone to free up all the “Other” space being taken up on the phone — in my case, around 2 GB.

Don’t do it. What that author failed to understand/mention is that the Other space includes all the files cached by your apps. So it’s a space gain only until you realize you’re missing all your podcasts, books, etc. and have to download them all again.

Specifically I noticed losing all my local data in Overcast (podcasts), Audible, Kindle, NewsBlur (RSS reader), and my various email and calendar apps…so pretty much everything I use regularly. After opening them up again, I’m back to square one in terms of lack of space.
