How to Permanently Erase Data from iPhone Before Selling

Posted by on 2 .

Early this morning, I got a few emails from my reader asking how to remove private data stored on iPhone permanently before selling. They also put emphasize on the word ‘permanently' as none of them are willing to get their privacy being leaked with the help of third-party data recovery software. I still remembered that my personal photos were posted on Facebook at someone's account, those photos came from the old device I sold online. I was pretty sure that the photos were deleted with the method provided by Apple: Erase All Content and Settings.


Research has shown that most of the mobile phones and smart phones are selling online with containing plenty of personal private data. This really is shocking! This is not just prove that the original users are not aware of the personal data will be leaked out, they don't care to remove private information, it also because we don't adapt the correct method to completely eliminate data from iPhone device. If you were smart enough and took a step forward, then you will find out that Erase All Content and Settings is not going to delete the data permanently. The data is still on your old iPhone unless it was overwritten by other digits. Fortunately, there is an app called iPhone Data Eraser which is developed with the aim to delete everything permanently on iPhone in a simple way.


iOS Data Eraser is a powerful data wiping tool that provides a much secure way to help you remove personal data on your iPhone. It writes a random set of digits to your iPhone a few times by utilizing the latest patent-protected algorithms. The data is absolutely non-recoverable even by FBI agents. So your privacy is under safe for sure when you give or sell the device to whomever.
