If you disable Whispersync, you will be missing out on some of the better Kindle features, including syncing your reading location, and backing up your annotations. This is where you will find the Whispersync for Books option. Scroll down and select the option to go to Settings menu.

Kindle Android app and Kindle Fire tablet – Open the Kindle app’s main menu, and then open the slide-out menu on the left.

Kindle iOS app – Go to the Settings menu, select the option for the Other options menu, and then select the Whispersync for Books option.

This will give you a pop-up menu where you can enable or disable Whispersync.

Kindle eReader – Go to the Settings menu, and then select Device Options > Advanced Options > Whispersync for Books.

Here’s how you can turn off Whispersync for just one Kindle app or device. This is not such a good idea if you also use the device for checking your email, just to name one example.

The first and easiest option is to turn on airplane mode, and keep your device from talking to the internet completely.

Whispersync is enabled by default, but there are a few ways to keep it from working. For example, if you loan a device, you probably don’t want to have the lendee’s annotations added to your account on Amazon.

This syncing feature is called Whispersync, and most of the time it is good to have the feature to have enabled, especially if you switch between reading on several apps and devices. But there are also times when syncing can be an nuisance. When Amazon launched the Kindle in 2007, one of its many killer features was the effortless way that the ereader automatically synced your reading location, bookmarks, notes, and highlights with Amazon’s servers (and for the 6 or 8 people who had two Kindles at the time, syncing between two devices was also pretty cool).
