"I got the latest iPhone 15, but I'm curious about the next model..."
"If I'm going to sell it anyway, I want to sell it for the highest price while its value is still high!"

With Dynamic Island on all models, the long-awaited adoption of a USB-C port, and further improvements in camera performance, the iPhone 15 incorporates many attractive features of the Pro model, setting a new standard for the standard model.

While it hasn't been long since its release and the iPhone 15 is highly popular in the used market, many of you might be wondering, "How much would it sell for now?" or "Where is the best place to sell it?"

This article will answer all your questions. From the latest iPhone 15 trade-in market price in 2025, to "5 expert tips to sell for even 1 yen more," and the best selling method for you, we will explain it all thoroughly. By reading this article to the end, you will know everything about maximizing the value of your iPhone 15.

Introduction: Is now the time to sell your iPhone 15? Trends in the trade-in market

To conclude, the iPhone 15 is "now is the perfect time to sell, before its value drops."

The iPhone 15, along with the iPhone 16, is a current model still sold by Apple (as of July 2025). Due to its very high demand in the used market, it is traded at an overwhelmingly higher price compared to older models. In particular, as it is the first model to transition from the Lightning port to the USB-C port, many users are looking for an iPhone 15 for compatibility with peripherals.

However, the value of a smartphone is destined to gradually decrease over time since its release. Especially, when information about the next new iPhone, which is announced every autumn, starts to emerge, the market price of current models tends to fluctuate.

In other words, getting an appraisal now, while its market value is still at its highest, is the smartest strategy to achieve a high trade-in price.

Don't lose out! 5 tips to sell your iPhone 15 for even 1 yen more

Since it's the latest model, you'd want to sell it for as much as possible, right? Here are 5 simple tips that anyone can use to boost their appraisal value.

Tip 1: Include all accessories

The most important point for a high-value buyback is to have all the accessories that came with the purchase. For the iPhone 15, check for the following accessories:

• USB-C charging cable

• Manuals

• SIM ejector tool

• Outer box (including inner box)

In particular, the new USB-C cable and a clean outer box affect the appraisal value. Even one missing item can lead to a reduction in price, so keep them carefully stored.

Tip 2: Sell at the optimal time

For new models like the iPhone 15, the golden rule is to sell before the next model is announced. When a new iPhone model is announced around September each year, the market value of older models tends to drop.

Also, demand in the used market tends to increase during bonus seasons and before the start of a new lifestyle, which can stabilize purchase prices. Don't procrastinate; getting an appraisal now, when demand is high and value is at its peak, will lead to a high-price sale.

Tip 3: Clean the device thoroughly

Before submitting your device for appraisal, clean it thoroughly. Simply removing fingerprints, sebum, and dust around the speaker and USB-C port with a soft cloth or air duster will significantly improve its appearance.

Appraisers are human too. A well-maintained device, rather than a dirty one, gives a favorable impression that it has been "cared for," potentially leading to a more thorough appraisal and, ultimately, a higher purchase price.

Tip 4: Back up and initialize your data

To protect your important personal information, such as saved data, user information, and Apple ID links, you must initialize your device before selling it.

1. Data Backup: Back up your data using iCloud or a PC.

2. Turn off "Find My": Go to "Settings" → [Account Name] → "Find My" and turn off "Find My iPhone." If this is left on, we cannot purchase the device.

3. Initialize: Go to "Settings" → "General" → "Transfer or Reset iPhone" → "Erase All Content and Settings" to restore it to factory settings.

While PRODIG uses specialized software to completely erase data from purchased devices, please make sure to initialize your device beforehand for your own privacy protection.

Tip 5: Unlock the SIM

As a general rule, all iPhone 15 models are sold SIM-free. Therefore, users do not typically need to perform the SIM unlock procedure themselves, unlike with previous models.

SIM-free devices, which can be used with any carrier, have the highest value in the used market, making the iPhone 15 a model with good prospects for high-price trade-in. This is also one of the significant advantages of selling an iPhone 15.

Compare selling methods! Which selling destination is right for you?

There are roughly three ways to sell your iPhone 15. Understand the characteristics of each and choose the method that suits you best.

Carrier trade-in

This method involves trading in your old device when purchasing a new smartphone from the same carrier.

• Pros: The process is simple and completed simultaneously with the new phone purchase.

• Cons: Often provides points rather than cash, and the appraisal value tends to be lower than specialized buyers.

Individual sales on flea market apps

This method involves selling to individuals on flea market apps like Mercari or Rakuma.

• Pros: You set the price yourself, potentially allowing you to sell for the highest amount.

• Cons: Requires effort and carries the risk of disputes between individuals. Fees are also deducted.

PRODIG (Specialized buyer)

PRODIG is a company specializing in buying smartphones. PRODIG focuses on in-person purchases at its Akihabara store.

• Pros: Expert staff accurately assess the value, allowing for immediate cash payment on the spot. In-person service provides peace of mind.
