What to Do With Old Phones and Laptops Before You Get Rid of Them

When you delete a file on most devices, the system typically just removes the pointer to that data and marks the space as available to be overwritten — the actual content often remains until something else happens to occupy that space. This is exactly why simple file deletion isn't a reliable way to prepare a device for someone else to use.

The fix is a full factory reset, not manual deletion

Modern phones and computers have a built-in factory reset option that either overwrites storage or relies on encryption to make the data unrecoverable, which is a fundamentally different — and far more reliable — process than deleting files one at a time.

Before you reset: back up what you want to keep

A factory reset is permanent. Make sure anything you want to keep — photos, documents, contacts, app data — is backed up somewhere else first, whether that's cloud storage or an external drive.

Phone checklist

Sign out of accounts and remove the device from account lists

Sign out of email, cloud storage, and any account you don't want linked to this device going forward. Many services also let you view and remove specific devices from your account's active session list.

Remove the SIM card

A SIM card can potentially be used to receive calls, texts, or verification codes tied to your phone number. Take it out and keep or destroy it separately from the device.

Turn off Find My Device or equivalent

Disabling device-tracking and activation-lock features before resetting prevents the device from being tied to your account in a way that could make it unusable for a new owner.

Run the factory reset from settings

Look specifically for a "factory reset," "erase all content," or "reset to factory settings" option — this is different from a simple restart or a partial reset.

Laptop and desktop checklist

Deauthorize licensed software

Some paid software limits the number of devices it can be active on. Deauthorizing it on the old device frees up that license for use elsewhere.

Sign out of browser-saved passwords and accounts

Browsers often store saved passwords locally. Signing out of the browser profile, in addition to the operating system reset, adds an extra layer of protection.

Use the built-in reset or reinstall option

Most operating systems include a "reset this PC" or equivalent option that reinstalls the operating system and clears personal files — check whether it offers a "clean data" option specifically, since some versions only remove files without securely erasing them.

What if the device is broken and won't turn on?

If a factory reset isn't possible because the device won't boot, physical destruction of the storage component (or the entire device, for smaller devices) through a certified electronics recycler is the more reliable option, rather than assuming a broken screen means the data is inaccessible to anyone else.

Common questions

Is deleting files enough before selling a device?

No. Deleting a file typically just removes the reference to it, not the underlying data, which can often be recovered with readily available software. A full factory reset, which overwrites or encrypts the storage, is what actually makes data unrecoverable on modern devices.

Does a factory reset remove everything, including my accounts?

A factory reset clears local data and settings, but it doesn't automatically sign you out of every cloud account or remove the device from account-linked device lists. Signing out and removing the device from your account settings separately is still necessary.

What's the difference between recycling and donating a device?

Both are reasonable options once a device is properly wiped. Donating gives the device a second useful life if it still functions well; recycling through a certified electronics recycler is appropriate for devices that are damaged or too old to be useful to anyone else.

Should I remove a SIM card before getting rid of a phone?

Yes. A SIM card can potentially be used to access calls, texts, or account verification codes tied to your phone number, so it should be removed and kept or destroyed separately from the device itself.
