Is a used iPhone 8 still usable? Recommended reliable and practical models for cost-conscious buyers

"Is it okay to buy a used iPhone 8?" "I'm looking for a smaller iPhone with Touch ID."

If this sounds like you, then a used iPhone 8 is a great option, especially now that prices are so affordable. Its compact size and convenient fingerprint authentication remain popular, and its performance is more than adequate for everyday use. What's more, prices in the used market are reasonable, and it pairs well with low-cost SIMs.

This article will re-examine the appeal of the iPhone 8 and explain how to purchase one affordably. Please use it as a reference when making your purchase.


Why is a used iPhone 8 a smart choice right now?

In the used smartphone market, the iPhone 8 remains highly popular due to its excellent balance of "price," "performance," and "size." Let's take a closer look at its specific appeal.

 

Easy to use with Touch ID & 4.7-inch display

The iPhone 8 features a physical home button and supports fingerprint authentication via Touch ID. Its ability to unlock seamlessly even when wearing a mask, unlike Face ID, continues to garner significant support. Furthermore, its 4.7-inch screen fits comfortably in the hand, a valuable feature among the increasingly larger smartphones of recent years. It's an ideal model for one-handed operation and is easy for female users to handle.

 

A11 Bionic chip provides sufficient basic performance

The iPhone 8 is equipped with the A11 Bionic chip, which offers ample performance for social media, video viewing, web browsing, and light gaming. It supports iOS 17, meaning there will be no major issues with daily use as of 2025. With its essential specs, it's suitable as a secondary device or a first smartphone.

 

¥30,000-¥50,000 cheaper than new, perfect for a two-device setup or secondary phone

While the iPhone 8 is no longer sold new, used models can be found for ¥10,000-¥20,000. This is ¥30,000-¥50,000 or more cheaper than the latest models, making it a cost-effective option for a secondary device, a phone for children, or a second business phone.


Points to consider when buying a used iPhone 8

When purchasing a used smartphone, it's important to consider not only the price but also factors such as "quality," "warranty," and "clear disclosure of condition." Here are some tips to help you confidently choose an iPhone 8.

 

Aim for a battery maximum capacity of "80% or higher"

An iPhone's battery is a consumable item and degrades with prolonged use. Apple recommends replacement when the capacity falls below 80%. When buying used, it's advisable to confirm that the battery's maximum capacity is 80% or higher. PRODIG displays battery status in advance, allowing you to choose with confidence.

 

Check for Blacklisting (aka "Red Rom") / Whitelisting and SIM unlock status

A "Red Rom" or blacklisted device is one whose communication is restricted due to issues such as overdue installment payments. Since such devices may not be usable after purchase, it's reassuring to choose a product with a permanent Red Rom warranty. Also, check if the SIM is unlocked (i.e., if it's a SIM-free device). If you plan to use it with a low-cost SIM, SIM-free is the best option.

 

A warranty or return policy of at least 30 days provides peace of mind

To prepare for any potential malfunctions, also check the warranty period and return policy. A warranty of at least 30 days, and ideally 90 to 180 days, from the seller, is recommended for peace of mind. PRODIG offers a standard 180-day operational warranty and a Red Rom warranty, providing coverage for any unexpected issues.

Pros & Cons of different purchase channels

There are various options for purchasing a used iPhone 8, each with its own advantages and disadvantages. Understanding these beforehand will help you make a choice you won't regret.

 

Risks of flea markets/private sales (blacklisted phones, no warranty)

While you can find an iPhone 8 relatively cheaply on flea market sites like Mercari and Yahoo Auctions, or through private sales, most of these transactions do not come with operational or blacklisted phone warranties. There's a risk of purchasing a device without adequate condition checks, so this is not recommended for beginners.

 

Features of Apple Certified Refurbished and Carrier Certified Used products

Apple's officially sold refurbished products and carrier-provided certified used products meet certain quality standards and come with warranties, offering peace of mind. However, prices tend to be somewhat higher, and the selection of models and colors may be limited.

 

Peace of mind points from specialty stores

Specialty used smartphone stores often have thorough quality control, including operational checks, cleaning, and clear indication of battery capacity. PRODIG offers a 180-day operational warranty and a blacklisted phone warranty, allowing you to make a purchase that balances both price and peace of mind.

After purchase, use a low-cost SIM wisely

The iPhone 8 supports major MVNOs, and combining it with a low-cost SIM can significantly reduce your monthly communication fees. It's an ideal choice for light users with low data usage or those considering it as a secondary device. Furthermore, it's possible to use two lines on one device by combining it with an eSIM.
