"I want to replace my iPhone 13 soon, but selling it is a hassle." "Which is better, trade-in or selling it outright?" Many people have these questions.
This article is a guide for individual users who want to safely dispose of their iPhone 13 and sell it for the highest possible price.

To summarize the conclusion first:

• To prevent data breaches, always personally verify initialization and sign-out

• Understand the four options: selling, trade-in, recycling, and keeping, then choose based on your priorities

• Combining in-store purchases at specialized used smartphone stores (e.g., PRODIG Akihabara) and online stores,
  the process of "sell → buy cheaply → rent if necessary" can be completed with a single brand

This is the general flow.
From here, we will gently explain the steps for selling your iPhone 13 from three perspectives: "safety, profitability, and practicality."

Conclusion: For a safe disposal, the shortest path is "initialize → get multiple quotes → choose the right channel"

First, let's get a rough idea of the best process for selling your iPhone 13.
Instead of immediately taking it to a store, keeping these three steps in mind will help you avoid mistakes.

1. Back up and initialize your data
   Back up data such as contacts, photos, and LINE to iCloud or your PC, then sign out of your Apple ID, turn off "Find My iPhone," and initialize the device. Doing this will help you avoid panicking at the store or having to enter your Apple ID password on the spot.

2. Get multiple quotes to understand the market value of your iPhone 13
   Check the trade-in pages of 2-3 carriers and used smartphone specialty stores, and roughly compare the purchase prices of devices with similar capacity and condition.
   Having an idea of "this is roughly the market price" will allow you to make a calm decision when presented with a price at the store.

3. Choose the channel that suits you (buyout / trade-in / recycling)

   • I need cash immediately → Buyout from a specialized store

   • I'm switching to a new iPhone right away → Trade-in with a carrier or Apple

   • It's broken and has no value → Manufacturer or local government recycling/disposal

The idea is to determine the outcome based on "what you prioritize."

By following these three steps, you can significantly reduce regrets such as,
"I could have sold it for more..." or "I panicked because I forgot to initialize it..."

Initialization Procedure to Prevent Data Leaks

The most frightening thing when selling an iPhone 13 is the possibility of it falling into someone else's hands with data still on it.
Smartphones contain not only photos but also credit card information and various login details. Here, we will outline the process for "safe initialization" that individuals must follow.

iCloud Sign-out / "Find My iPhone" Off / Activation Lock Removal

First, completely disconnect your iPhone from your Apple ID.

1. Open the "Settings" app

2. Tap on your name (Apple ID) at the very top

3. Tap "Find My" → "Find My iPhone" and toggle the switch off

4. Enter your Apple ID password to turn it off

5. Return to the Apple ID screen and tap "Sign Out" at the bottom

6. Follow the instructions to complete the logout

Completing these steps will also remove the Activation Lock, allowing the next owner to set up the device without your Apple ID.
Recently, there have been many cases where devices cannot be assessed due to remaining Activation Locks, so make sure to personally verify this procedure.

Backup & Erase All Content and Settings

Once your Apple ID is disconnected, proceed with backing up your data and initializing the device.

• First, back up to iCloud or your PC (Mac's Finder / Windows' iTunes)

• Once the backup is complete, go to "Settings" → "General" → "Transfer or Reset iPhone" → "Erase All Content and Settings"

This alone will restore your iPhone 13 to a nearly factory-fresh state.
After initialization, confirm that the initial setup screen, such as "Hello," is displayed.

Common Mistakes and On-the-Spot Solutions

Common mistakes made by individuals include the following:

• Forgetting the Apple ID password and bringing the device in without being able to turn off "Find My iPhone"

• Initializing without signing out of iCloud, leaving the Activation Lock on

• Forgetting to back up and losing important photos or LINE chat history

If you forget your password, try resetting it through Apple's "Forgot Apple ID or password?" page.
If you absolutely cannot unlock it, do not take it to a store as is; consult Apple Support first. It's not uncommon for devices with Activation Lock still active to be ineligible for purchase.

Four options: "Sell," "Trade-in," "Recycle," "Keep"

When considering letting go of your iPhone 13, there are four main options:

1. "Selling" at a buyback store or flea market

2. "Trading in" with a carrier or Apple

3. "Recycling" with a manufacturer or local government

4. "Keeping" as a secondary or backup device

Understand the characteristics of each option and choose the one that suits your personality, purpose, and lifestyle.

Selling: For those who need cash quickly

This method involves taking your device to a specialized used smartphone store or a chain store's buyback counter for appraisal.
The advantages are as follows:

• Immediate cash payment (cash on the spot or bank transfer)

• Well-maintained iPhone 13s often fetch a higher price than trade-ins.

• Even junk or cracked screens may have some value depending on their condition.

On the other hand, the disadvantages include:

• If the condition is poor, it may sell for less than expected.

• Appraisal standards vary by store, so it's easy to feel shortchanged if you don't know the market price.

are available.
If you can go to places like Akihabara, selling at a specialized phone store (e.g., PRODIG Akihabara) while consulting with staff is likely to lead to greater satisfaction with the appraisal.

Trade-in: For those upgrading to a new iPhone immediately

Carrier stores and Apple Stores offer a "trade-in" service for iPhone 13, where the trade-in value is directly deducted from the purchase price of a new iPhone.

• Advantages

  • The process is simple and completed at the same time as the model change.

  • It feels like less money is leaving your wallet, so the psychological burden is lighter.

• Disadvantages

  • It's a "discount" rather than cash, so it's not money you can use freely.

  • Appraisal values are often lower than buyback prices.

If you're the type who thinks, "I'm getting a new iPhone anyway, so I don't care about the details," then a trade-in is a good fit.
However, if you want to sell it for as high a price as possible to put towards your next device or living expenses, prioritize selling it outright.

Recycling: A last resort if it's broken and has no value

If the screen is completely black, the power doesn't turn on, or it's clearly in need of repair, the buyback price may be close to zero.
In such cases, another option is to use recycling services from Apple, local governments, or certified operators.

• It's recycled as a resource, reducing environmental impact.

• Some collection boxes can be used for free.

However, devices sent for recycling generally cannot be returned, so if you're still thinking, "maybe it's still usable...", consider buyback or repair possibilities first.

Keep it: Utilize it as a secondary device

The iPhone 13 is still a capable model in 2025.
If the battery has slightly degraded but it's still perfectly usable, it might be more beneficial to use it as a secondary device than to sell it.

• Carry two phones, one for work and one for personal use.

• Insert a low-cost SIM and use it as a secondary line.

• Use it as a Wi-Fi-only device, dedicated to videos, music, and games.

Thus, it's also a good idea to pause and consider if you really want to let go of it before selling it.

Preparation and appraisal points for selling your iPhone 13 at a high price

If you're going to sell it anyway, you want to sell it for even one yen more.
Here, we will explain the points that affect the appraisal value at buyback stores and flea markets, along with preparation tips.

Checking the exterior, screen, battery, and network usage restrictions

The appraisal value is largely influenced by the following items:

• Scratches, dents, and paint peeling on the exterior

• Cracked screen, bleeding LCD, touch malfunctions

• Maximum battery capacity (Settings → Battery → Battery Health)

• Network usage restrictions (whether there's outstanding payment)

Here's an idea of the condition based on commonly used ranking:

Even for the same iPhone 13, the buyback price can vary greatly between A and C ranks.
Consider routinely protecting it with a case and screen protector as an "investment" for resale.

Accessories, box, receipt, and SIM-free status

Surprisingly, people often forget about accessories like the box.

• Having the box, cable, and manual together is often valued as a "complete set for the next owner."

• A receipt (proof of purchase) from an electronics retailer or online store helps distinguish it from stolen goods and provides reassurance.

Also, whether it is SIM-free or not is a key point.
Even iPhone 13s purchased from carriers can be SIM-unlocked from your account after a certain period.
Doing this before selling will make it more appealing as a "device that can be used with various carriers."

Pre-cleaning and tips for taking photos for flea market apps

Whether it's in-store buyback or a flea market app, first impressions are very important.
Wipe off fingerprints and dust with a soft cloth, and remove cases and stickers before bringing it in.

If you're selling on a flea market app, the way you take photos can affect sales.

• Take photos in a bright area, avoiding strong shadows.

• Include shots of the front, back, sides (all 4), and close-ups of any scratches.

• Also include shots showing it in operation, such as "powered on" or "charging."

In the description, honestly stating the location of scratches, maximum battery capacity, and presence of accessories can help avoid trouble and facilitate a smooth sale.

Ideas for repurposing a "still usable" iPhone 13

If you found the appraisal value lower than expected, or you're not in a hurry to get cash,
it's a perfectly valid option to forgo selling and repurpose your iPhone 13.

Carry two devices to separate your smartphone life

Having two devices can make your smartphone experience surprisingly convenient.

• Main line: For calls, messages, payment apps, etc., the center of your life.

• Secondary line: For social media, gaming, video streaming, etc.

If you consolidate your social media accounts on a secondary device, you'll be less overwhelmed by notifications, and your main device's battery will last longer.
By adding a low-cost SIM, you can start your "secondary smartphone life" for just a few hundred yen per month.

Use it as a dedicated entertainment device at home

With just Wi-Fi, an iPhone 13 can be a perfectly capable entertainment device even without a cellular plan.

• Connect music streaming services to speakers.

• Keep it permanently on the sofa or by the bed for video viewing.

• Use it as a dedicated device for e-books and manga.

In the sense that "you don't have to worry about the battery draining" and "you can concentrate because you won't get calls,"
it's not a bad idea to use it extensively at home instead of selling it.

Use it as a monitoring, security, or smart home controller

Another way to use it is to place it in a fixed location.

• Install a monitoring camera app to check on pets or children's rooms.

• Use it as a dedicated remote control for smart locks, lighting, air conditioners, etc.

• Place it at the entrance or in the living room to display family to-dos or calendars.

There are many "uses that are only possible because it's not used as a phone."
Compare which one is more valuable to you compared to the selling price.

How to properly dispose of and recycle

If you have an iPhone 13 that is too old to sell, or broken and you are uneasy about keeping it,
it is important to dispose of and recycle it properly.

Collection boxes from local governments and electronics retailers

Many local governments and electronics retailers have "small appliance collection boxes."
Simply placing your device in one allows metals and plastics to be recycled, reducing environmental impact.

• Check the local government's website beforehand to see if "smartphones are accepted" and if "individuals can use the service."

• Initialize and sign out before depositing.

Especially for individuals, disposal costs are often free,
so it's useful to remember this as the "final option for broken, valueless smartphones."

Apple's Recycling Program

Separate from trade-ins, Apple also offers a dedicated recycling service.
Some devices, even those not eligible for trade-in, can still be taken for recycling, making it suitable for those who "prefer to use an official service."

• Bring to an Apple Store

• Complete the process online and mail the device as instructed (check Apple's official website for details)

Again, always initialize and sign out yourself before proceeding.

FAQ: Common Questions Before Selling an iPhone 13

Q. How much initialization is "safe"?

A. For personal efforts, your security will be considerably high if you complete these three steps:

1. Signed out of iCloud and Apple ID

2. "Find My iPhone" turned off and Activation Lock released

3. Returned to factory settings by "Erase All Content and Settings"

In this state, even if the device falls into the hands of a third party, it is highly unlikely that your photos or LINE data will remain.
If you're still uneasy, it's reassuring to ask store staff, "Could you please confirm if it's initialized?"

Q. I forgot to deactivate Activation Lock and already reset it...

A. Turn on the power once, connect to Wi-Fi from the "Hello" screen,
and if you can enter your Apple ID and password, you can log in again there to redo the lock deactivation.
If that doesn't work, try resetting your password from Apple's support page.

If you try to sell it without being able to deactivate it, it will result in it being unpurchasable or a significant price reduction.
Take a moment to confirm that the lock has been deactivated before bringing it to the store.

Q. What's the difference between recycling and trade-in?

A. Roughly speaking,

• Trade-in → A system used as a "discount on the next device you buy"

• Recycling → A system for "disposing of as a resource"

For a device like the iPhone 13, which still has value, it's generally best to first consider selling or trading it in,
and only turn to recycling if it's too broken to be reused.

Q. If I'm going to repurpose it, what's the best way to use it?

A. The top three popular personal uses are:

1. Secondary smartphone for dual-wielding (cheap SIM + SNS/hobby use)

2. Dedicated device for videos, music, and games at home

3. Fixed device for security camera/smart home remote control

If you're not looking to convert it to cash immediately but feel it's a waste to leave it in a drawer,
you might want to try one of these three options first.
