How to Get Your iPhone Ready to Sell: A Super Simple Guide

01/11/2025

5 Mins

Got an old iPhone and want to sell it to help pay for a new one? That's a brilliant idea! It’s a great way to get some money back in your pocket. Before you sell it, there are two really important things you must do: save a copy of all your stuff and then wipe the phone clean so all your secrets are safe.

Giving Your iPhone a New Home

Loads of people in the UK buy second-hand iPhones, so you won’t have any trouble finding someone who wants yours. But before you hand it over, there are a few simple jobs to do. This isn’t just to keep your private things safe – like your photos, messages, and banking apps – it’s also to make sure the new owner gets a phone that feels brand new.

This guide will show you exactly what to do, with no tricky words. We’ll look at:

  • How to save all your important bits and bobs so you don’t lose anything.
  • The proper way to wipe the phone completely clean.
  • How to give it a good polish so it looks amazing for the new owner.

Getting these steps right will help you get more money for your phone and makes things easier for the person who buys it. Everyone's a winner!

First Step: Save All Your Memories

Before you do anything else, the very first job is to back up your iPhone. Think of it like packing up your favourite toys and treasures before you move house – you wouldn't just leave them behind! Losing years of photos, friends' numbers, and messages would be a total nightmare, so this is the most important part of getting your iPhone ready to sell.

There are two easy ways to do this: using iCloud or plugging it into a computer.

How Do You Want to Save Your Stuff?

Let's have a quick look at the two best ways to back up your iPhone, so you can pick the one that's best for you.

What's it like? iCloud Backup Computer Backup (iTunes/Finder)
Best For Being super easy, as it does it by itself without wires. Big backups, if you want to keep your stuff on your own computer.
Storage It uses your iCloud storage (5GB is free). You might need to pay for more space. It uses the space on your Mac or PC. This is great if you have lots of photos and videos.
How it Works It saves everything automatically over Wi-Fi when your iPhone is charging. You have to plug your iPhone into a computer with a cable to start saving everything.
Getting Stuff Back This can be a bit slow, as it needs the internet to download everything again. This is much faster, as the information goes straight from the computer to the phone.

Really, it's all about what you find easiest. For extra safety, especially if you have things you really can't lose, you could look at dedicated data backup solutions that are like super-safe storage lockers for your memories.

Getting this right doesn't just keep your memories safe; it can also help you get a better price. Buyers trust you more when they know you’ve done everything properly.

Once your backup is all done and safe, you can move on. If you're wondering what to do when you get a different phone, check out our guide on how to set up your second-hand iPhone without losing data.

How to Wipe Your iPhone Completely Clean

Now that your memories are safely tucked away, it’s time for the most important step before selling your iPhone: wiping it completely clean. This is called a factory reset, and it gets rid of all your personal information, settings, and apps. It makes the phone just like it was when it was new in its box.

You really don't want the new owner finding your private messages, photos, or accounts you're logged into. Just deleting things one by one doesn't work properly and can leave bits behind. A full factory reset is the only way to be 100% sure your information is gone forever.

The Simple Steps to Erase Everything

This might sound a bit technical, but Apple has made it really, really simple. It only takes a few taps in the Settings app. The main things you’ll need to do are sign out of your Apple ID and turn off 'Find My iPhone' before you wipe all the data.

For a step-by-step guide, you can follow our simple instructions on how to reset an iPhone to factory settings. It’ll show you exactly what to press on each screen.

Making Your iPhone Look Its Best

How things look is really important, especially when you’re selling your phone. Let’s be honest, a clean, shiny iPhone will always look nicer and will get you more money than a grubby one. It’s time to give your phone a little clean-up.

Start with the easy bits: gently wipe away fingerprints and smudges from the screen and back. A soft, clean cloth – like one you’d use for cleaning glasses – is perfect for this. Whatever you do, don't use strong cleaning sprays, as they can damage the special coating on the screen.

Next, look at the little nooks and crannies. Carefully clean out any dust and fluff from the charging hole and speakers. A soft-bristled brush, like a clean, small paintbrush, is great for gently getting any bits out.

Being honest about the phone's condition helps the buyer trust you. A phone that looks looked after is a huge plus point!

Getting Everything Ready for the Buyer

What makes your iPhone look extra special to someone wanting to buy it? Having all the original bits and bobs! It's worth having a hunt for the original box, charging cable, and plug. Having these makes your advert look much more professional and trustworthy.

And here’s something very important: take your SIM card out! It’s easy to forget, but you'll definitely need that for your new phone.

Once you’ve got everything together, it’s time to take some great photos for your online advert. You want clear, bright pictures that show off your super-clean phone from all sides. If there are any little scuffs or scratches, take a picture of those too. Being honest builds trust and helps people feel happy about buying from you.

With everything ready, you just need to decide where to sell your phone. To get the best deal, have a look at our guide on where to sell your iPhone for the best price for some excellent ideas.
