With the recent surge in smartphone prices, more and more people are considering purchasing used smartphones.

"I want to buy a used iPhone online, but which site is best?"
"How do I choose a used iPhone without making a mistake?"

Many people probably have these questions. This article introduces recommended sites for buying used iPhones and tips for choosing one without fail.

Before Buying a Used iPhone: Pros and Cons to Know!

By understanding the pros and cons of purchasing a used iPhone, you can minimize regret after your purchase.

Advantages of Used iPhones

• Lower Price
  Compared to new devices, used iPhones are more affordable, significantly reducing costs.

• Freedom to Purchase Device Only
  You can buy just the device without a communication contract, and by combining it with a cheap SIM, you can also reduce communication fees.

• Choose based on extensive reviews and ratings
  Since many users use these models, you can understand the performance and features in advance.

Disadvantages of Used iPhones

• Battery Degradation
  Depending on the usage period, the charging capacity can significantly decrease, potentially dropping to 80% of its maximum capacity after 2.5 years of use.

• Security Risks
  If purchased from an malicious seller, there is a risk of activation lock or jailbroken devices.

• Missing Accessories
  Accessories such as charging cables and SIM cards may not be included, requiring separate purchases.

While used smartphones lower the barrier to purchase, they also come with inherent risks. Knowing these risks beforehand can lead to a more satisfying purchase.

Additionally, some selling sites explicitly state information about potential concerns, so thoroughly checking product details before purchasing can significantly mitigate disadvantages.

4 Key Points to Consider When Choosing a Used iPhone Website

Choosing a website when purchasing a used iPhone is crucial to avoid post-purchase issues and ensure a secure transaction.
When selecting a site, it is advisable to prioritize the following four points:

• Reliability

• Warranty Period

• Return Policy

• Support System

We will explain each of these in detail.

Reliability: Check User Reviews and Track Record

The reliability of a site can be judged by user reviews and its operational track record.

Specifically, check ratings on third-party sites like Google, Rakuten, and Kakaku.com. A star rating of 4 or higher and over 1000 reviews generally indicate high reliability.

Regarding operational track record, it is recommended to choose sites with over 5 years of experience.

Long-term operation is a sign of stability, reducing the risk of sudden closure.

The presence of physical stores is also important; if available, face-to-face support can be expected in case of any issues.

Warranty Period: Purchase with Greater Peace of Mind with a Longer Warranty

It is recommended to choose a sales site with a minimum 90-day warranty, ideally six months.

When comparing warranty details, thoroughly check for battery replacement, screen repair coverage, and warranty application conditions.

PPRODIG offers a long 180-day warranty, along with return and exchange options.

Return Policy: Check Handling of Issues

The return policy is an indicator of how issues are handled after purchase.

Ideally, choose a site with a return period of 14 days or more and a full refund guarantee for initial defects.

The difference in how issues are handled is also important.

PRODIG offers a 30-day return guarantee, allowing returns for any reason.

Support System: Prioritizing Post-Purchase Follow-up

A robust support system directly contributes to long-term user satisfaction.

Compare 24-hour customer support, inquiry options via chat or email, and the presence of repair centers.

Choosing a site that promptly addresses post-purchase issues and questions ensures peace of mind when using a used iPhone.

Considering these points when choosing a used smartphone purchasing site will help reduce post-purchase risks.

Each of these sellers has distinct characteristics and reliability.

Next, we will introduce the features of each seller.

Additionally, PRODIG evaluates exterior conditions in three grades from A to C, with A receiving high marks for an appearance that is as good as new.

Nicosuma stands out with its 1-year long-term warranty and detailed battery level display.

Battery levels are shown in 1% increments, and only products with 80% or more are handled.

While prices may be slightly higher than competitors, it is suitable for buyers who prioritize quality.

Used iPhone Market in 2025: Latest Trends and Future Outlook

The used iPhone market in 2025 will be significantly influenced by the release of new models and the widespread adoption of 5G-compatible devices.

Specifically, with an increasing number of consumers prioritizing sustainability, the used market is expected to expand.

This trend is also due to a growing number of consumers choosing used products to reduce environmental impact.

In the future, the used iPhone market will need to balance price competition and quality assurance.

Changes in the Used Market Due to New Model Releases

The release of new models significantly impacts the used market.

When new models come out, the prices of older models temporarily drop, making it an opportune time for buyers to purchase at a discount.

When a new iPhone is released, models from a year ago can drop to about 30% of their new price.

On the other hand, the launch of new models can also lead to a decrease in demand for used older models.

Especially if there are significant functional differences, older models tend to become temporarily unpopular.

However, if the price drops, the cost-performance ratio improves, which can be an opportunity for buyers, and targeting this is also recommended.

Increased Demand for 5G-Compatible Models and Price Trends

Demand for 5G-compatible iPhone models has rapidly increased with the spread of 5G networks.

Specifically, models from iPhone 12 onwards are in high demand due to 5G compatibility, leading to relatively high prices.

Older iPhone 15 Pro models are available in the used market at about 70% of their new price.

Future price trends predict a further increase in demand for 5G-compatible models as 5G networks become even more widespread.

Expanding Used Market Due to Emphasis on Sustainability

With an increasing number of consumers prioritizing sustainability, the used iPhone market is steadily expanding.

Choosing used products helps reduce electronic waste and promotes recycling, thereby lessening environmental impact.

This trend is particularly strongly supported by younger generations and environmentally conscious consumers.

While the expansion of the used market brings more reliable selling sites and a wider variety of options for consumers, malicious sites are also increasing, making careful site selection crucial in the future.

Summary

To ensure a safe and satisfying used iPhone purchase, it is important to check the following points before buying:

• Reputable selling sites
  Check return policies and warranty details.
• Model and condition
  Check exterior appearance and battery status.

When purchasing a used iPhone, it is crucial to especially check the battery level and exterior condition, and also consider how issues would be handled if they arise after purchase.
