So a new iPhone has piqued your interest, and you want to upgrade to the latest model as soon as possible. But what are you going to do with your old device? There are several options available. You could give it away, trade it in with your service provider, sell it, or recycle it.

Your iPhone most likely contains sensitive private data that you need to delete. You want to keep your personal information private. Leaving personal information on an old device may risk your security and privacy.

So, how do you properly wipe an iPhone without risking leaving residual data? Is it sufficient to delete the files and hand the phone over to a new owner? This article will demonstrate how to securely erase your data from your iPhone before selling or trading it.

Part 1. What Happens When You Don't Wipe Your Old iPhone 11 Series?

Selling or trading in your iPhone is a great way to make money while also helping the environment. However, if you do not first remove personal data from your iPhone, you may become an easy target for hackers. Fortunately, Apple has made it simple to delete all content and settings on iPhones as part of its ongoing efforts to improve customer privacy protection. And, no, you don't need any special iPhone hacks or tricks to accomplish this—you can do it right from your phone.

Before trading in or selling your old iPhone, it is recommended to completely wipe off all personal information that may still be stored there. Better yet, just clear the data on your mobile phone entirely. When you sell or recycle your phone, you have yet to learn where it ends up. If you keep that personal information there, it will travel with the phone. Criminals can easily use that data, including financial account information, frequently visited locations, and even behavioral biometrics, for fraud, scams, and identity theft. That's just one cybersecurity secret hackers want you to keep hidden.

Part 2. Back up Your Old iPhone 11 Series before Erasing

It would be best to erase all your data before trading in your old iPhone for a discount on a new one, selling, giving it away, or recycling it. This ensures that no one has access to the goldmine of personal information we all keep on our phones. However, before you reset your iPhone, make a backup that you can use to set up your new iPhone and return to if you lose contacts or photos on your new phone. Here are three methods for backing up your iPhone.

Back up iPhone to iCloud.

Using iCloud to back up my iPhone is one of the simplest ways to learn how to back up my iPhone. You can back up your data to the cloud without connecting your phone to the system. Apple gives every user 5 GB of free storage space by default. After you've used up your free storage, you may need to buy more. The following are the steps for backing up your iPhone to iCloud:

Step 1. Navigate to Settings > iCloud and sign in with your Apple ID and password.

This is a quick and simple backup of your iOS device by connecting it to your system via a USB/lightning cable.

Under the Reset section, there are two options: Reset All Settings (Wipe) and Erase All Content and Settings (Factory Reset).

That may be there is also a third option to make sure that all sensitive material from your old iPhone is wiped clean before you sell it. That is by way of third-party applications, such as Wondershare's Dr.Fone - Data Eraser.

Part 4. FAQs about Sell iPhone 11 Series

1. How Much is Your Used iPhone 11 Series Worth?

How much your old iPhone 11 Series will sell significantly depends on where you sell it, its present condition, and when you ultimately want to let go of it. A used 128GB iPhone 11 in excellent condition can sell from $300 to $550, depending on the store you sell it on.

Take note also that the older your iPhone gets, the lesser its selling worth will be. With that said, it's best to look for a great place to sell your iPhone for a good price as soon as possible.

2. Does Factory Reset Completely Wipe Your iPhone?

No. While factory resetting, or hard resetting, aims to delete all data and settings stored in your iPhone, without using specifically-crafted third-party applications, such as the Dr.Fone, some deleted files may appear not erased at all. The system just removes the pointer and marks the sectors as available; the files you wish to delete through factory reset are still there.

Using Dr.Fone permanently erases the deleted files, ensuring that no one can ever recover them, even with professional data recovery tools and applications.

3. What Else Should You Consider Before Selling a Used iPhone 11?

Before selling, giving away, or trading in your device, you should transfer information to your new device and remove all personal information from your old device. It is recommended that you use a third-party application to make sure all your contacts, calendar reminders, documents, photos, or any other iCloud information while signing in to iCloud with your Apple ID will be deleted.

After getting rid of all the important files on your used iPhone, thoroughly clean your phone, gather all its original accessories, and select a good place to sell it.


As you can see, there are plenty of options for factory resetting your iPhone device, whether it's your iPhone 11 Series or not, and you're bound to find the one that's right for you! With that said, Dr.Fone - Data Eraser guarantees complete data deletion, which means that even the most sophisticated data recovery program cannot recover the deleted data.
