12 Things to Check Before You Sell Your Old Phone



12 Things to Check Before You Sell Your Old Phone

I’m about to sell my old phone. If you’re selling yours, too, here’s everything you need to know before plunking it down on the table and receiving your cash in exchange.

1. Check the Water Damage Indicator

Next, check the water damage indicator. If you look at your phone, there’s a small dot or line on the back of it that indicates whether or not it has been exposed to water. If there is a line, then your phone was damaged by water and may need to be replaced due to corrosion issues. However, if you don’t see any discoloration at all (or if it only appears faintly), then your phone has probably been fine after being submerged in water and does not require repair or replacement.

2. Make Sure You Transfer Everything

It’s important to make sure that your old phone is clean and empty before you sell it, or else the buyer will have no way of knowing what they are buying. You should also ensure that all of your data is transferred over, as well as any contacts and text messages that are stored on the device itself. This can be done using an app like Google Drive or iCloud which will allow you to back up all of this information onto cloud storage so that it is always safe and accessible.

3. Fully Charge Your Phone Before Selling It

One of the most important things to do before selling your phone is to make sure it’s fully charged. If you’re selling your old phone, it’s important that the buyer can see that the device powers on. If the phone is low on battery and doesn’t have enough power to turn on when they first try to use it, there’s a chance that they won’t be able to tell whether or not there was anything wrong with the device in question.

A fully-charged phone will allow you to check all of its other functions as well as test its battery life. This way, if someone comes back later saying their new phone isn’t working right, you’ll have no trouble diagnosing whether or not it needs repair or just needs a fresh charge

4. Back Up Your Data

Back up your photos, videos, and contacts. If you haven’t already done so recently, back up all of the data on your old phone before selling it. Backing up your information is a great way to protect yourself against losing important files in the event that something goes wrong with the sale.

  • To back up photos and videos: Make sure that you have an SD card that can be removed by both phones (or use cloud storage). Then connect them via USB cable and select “Copy images” or “Transfer images” in iTunes/Windows Media Player (depending on which operating system you’re using). This will transfer all pictures from one device to another automatically—no need for manual uploads!
  • To back up contacts: Go into Settings > Accounts & Passwords > Add account > Gmail or Exchange (depending on which one you have) then click “next.” Follow instructions for adding account details until prompted by email address instead; enter a new email address here instead. Scroll down until finding “Email addresses,” then tap add plus sign icon next to where it says add new contact info.” Enter your name then save changes once done filling out the information.

5. Sign Out of iCloud and Remove Find My iPhone

  • Sign out of iCloud: Open the Settings app on your old iPhone, tap your name at the top, then tap Sign Out. This will log you out of iCloud and remove all your data from the service’s servers. If you have any documents stored in iCloud Drive, make sure to download them before signing out.
  • Remove Find My iPhone (or Find My iPad): Head over to and sign in to your account if asked for verification; after that, click Manage Your Devices in the menu bar across the top of the screen to see a list of devices associated with it and select one from that list to remove its location-tracking ability using Find My iPhone/iPad or Find My AirPods (if applicable). You’ll need a passcode or password to do this; once you’ve removed it from Find My iPhone, remember not to enable Find My iPhone again later so no one can track down your device before it’s sold!
  • Restore phone/tablet back to factory settings: You may want to restore an old phone so that it runs like new again–but don’t forget this step first! Restoring an old device takes time–and in some cases requires internet access when restoring apps–so make sure everything on it has been backed up beforehand so nothing gets lost during restoration time!

6. Encrypt Your Phone and Factory Reset It

Encrypting your phone and factory resetting it are two important steps to ensure that no one else can get their hands on the personal data contained within your device.

Once you encrypt your device, you’ll be asked to set a password or PIN code for unlocking the screen. This is essentially an extra layer of security that protects your data from being stolen by thieves. And when you factory reset your device, any information saved on its internal storage will be completely erased so there’s nothing left behind that could give away sensitive information about yourself or others. Here’s how:

  • Turn off Find My iPhone (if applicable)
  • Reset iCloud Account Password – this only works if you have access to another device with iCloud enabled
  • Turn off Find My iPhone (if applicable)

7. Delete Old Photos and Clean Up Your Storage

You’ll want to remove anything that you’re not going to need. This means that all those photos and videos can go, as well as any apps and music you don’t use. You might choose to also delete text messages, call logs and email messages that are no longer useful or relevant. If you were keeping notes in a note-taking app on your old phone, delete those too. If there are calendar events or browser history entries from last year that won’t come up again this year (or even next decade), get rid of them!

8. Remove Sim Card and Memory Card, if Applicable

Remove sim card and memory card, if applicable.

Your SIM card is your phone number and the information that sends calls to it. It’s a small rectangle that can be removed from a slot on the side of your phone or behind its battery. Removing this will prevent anyone who steals your old phone from using it on their network, which could lead to expensive international calls or data charges for you. Additionally, removing any memory cards can prevent thieves from accessing photos or videos of yourself or people you know on both personal computers and mobile devices—and they could be used as evidence if someone tries to claim that they’re not guilty of whatever crime you think they may have committed while using your device!

9. Clean Off Dust and Grime From the Charging Port and Headphone Jack

To clean the charging port, use a cotton swab dipped in alcohol. The same goes for your headphone jack.

If you have time, you can also use a vacuum cleaner to suck out any particles that may be stuck inside the charging port or headphone jack. Just make sure not to leave the vacuum on too long and suck out anything else that might be loose in there (like screws!). If you don’t have access to one, try using a toothbrush and toothpaste: Dip your toothbrush into some paste and scrub away at any grime or dirt until it’s all gone! You could also use Q-tips—just make sure they’re made from 100% cotton so they don’t scratch any sensitive parts inside your phone as you clean them out.

Finally, if none of these methods sound appealing to you but you still want an alternative way of getting rid of pesky dust clumps without doing much work yourself there’s always compressed air! This method uses pressurized air which helps blast away dust particles so they no longer interfere with how well your device runs when turned on again (if possible).

10. Gather All the Accessories That Came With Your Phone and Sell Them in a Bundle if Possible

If you don’t have all the accessories, it’s okay to sell your phone without them. But if you do have all of the original accessories that came with your device, these can be sold together as a bundle.

If you want to sell each accessory separately, check the online marketplace first to make sure that people are actually buying them. For example: if the battery for a certain phone is only worth $2 used ($3 new), but there are no buyers for that part of the bundle on eBay or Amazon, then it might not be worth it for you to sell just that battery rather than selling both batteries together (as well as other parts of the bundle).

11. Consider Adding a Tempered Glass Screen Protector to Help Increase the Value of Your Phone

If you’re selling your phone to a buyer who’s also looking to upgrade, consider adding a tempered glass screen protector. These protectors can be more durable than plastic protectors and won’t add bulk to your phone. They’re easy to install and remove, so you don’t have to worry about taking them off when you sell your old device. Tempered glass is scratch-resistant, too, which means that it will last longer than other types of screen protectors.

12. Add a Fresh Case to Make Your Phone Look Brand New Again and Help It Sell Faster

As you’re preparing to sell your old phone, you may want to consider adding a fresh case. A brand new case will help make your device look brand new again and can help it sell faster.

Selling an old phone with a slightly used or damaged case—like one with scratches or cracks in the plastic—can decrease its value when you try to trade it in for cash or credit at a store like Best Buy or Apple. It’s important that the case is in good condition so that it doesn’t lessen the value of your device.

To ensure that your phone sells for as much money as possible, we suggest choosing one of these tips:

Choose a case that has no visible damage but still protects against drops and falls (a sturdy plastic shell will do the trick). This way, buyers know they can get their money’s worth without having to worry about any cosmetic issues down the road.* If possible, choose a simple yet stylish design over something flashy like rhinestones or gold accents; flashiness detracts from functionality when trying to attract potential customers.* Make sure there aren’t any loose pieces attached since this can lead people away after realizing how difficult it would be to start using such an item without having everything properly fit together first.* Consider getting rid of any bulky accessories such as extended batteries before giving them away.

In Conclusion

Now that you know how to get your old phone ready for resale, you’re ready to sell it! Whether you’re going through an online marketplace or a brick-and-mortar store, following these steps will ensure that your device is in the best possible condition. This way, you stand to make more money—and have fewer headaches—when selling your phone.
