"I want a smartphone that fits in my pocket."

In recent years, the smartphone market has seen an increase in larger models. Are you thinking along these lines?

If you're looking for a small new smartphone, it's hard to find, and the options are limited. That's why used small smartphones, which are affordable and offer access to popular past models, are attracting attention. However, many people are hesitant to take the plunge, worrying that "the battery on a used item might be degraded" or "there might be invisible defects."

In this article, experts thoroughly explain everything from the pros and cons of choosing a used small smartphone to how to choose one you won't regret. Furthermore, we introduce PRODIG's carefully selected top 10 recommended models, divided into iPhones and Androids. By reading this article, your worries about choosing a smartphone will be resolved, and you'll be able to find the perfect device for you.

Pros and Cons of Choosing a Used Small Smartphone

Pros

In recent years, smartphones have tended to increase in size. This is due to the growing number of users enjoying rich content such as high-resolution video viewing, mobile games, and social media. However, for smartphones that are constantly carried in hand and often operated with one hand, this increase in size is not always an advantage. In particular, for those with smaller hands or those who prioritize portability that fits neatly into a pocket, it can lead to reduced operability and convenience.

This is where smaller smartphones, which were once mainstream, come into focus. The used market offers a wide range of popular smaller models, providing the significant advantage of being able to choose models that are no longer available new. For example, while Apple's iPhone 13 mini and iPhone 12 mini are no longer officially sold new, good condition models can sometimes be found in the used market. Additionally, Android also has high-performance yet compact models such as the Google Pixel 4a and Xperia Compact series. These models can be purchased significantly cheaper than new ones, making them very attractive for those who prioritize cost-effectiveness.

Furthermore, small smartphones are also suitable for use as a secondary device. For those who want to use different phones for personal and work use, or as a backup when the main smartphone's battery dies, purchasing an affordable used small smartphone as a second device is a smart option. Being able to meet such diverse needs is a major advantage of choosing a used small smartphone.

Cons

When choosing a used smartphone, it's important to understand some of the drawbacks. The biggest concern is battery degradation. Smartphone batteries are consumables, and their maximum capacity decreases with longer use. Used smartphones have been used by previous owners for a certain period, so their battery life may be shorter compared to new ones. The degradation may be even more advanced if the battery was frequently subjected to heavy use.

Next is the cosmetic condition. As a used item, there may be scratches, dents, or paint peeling on the screen or body. While retailers usually grade the condition of their products, it can be difficult to check every detail from photos alone. In particular, minor scratches on the screen might be noticeable during use.

Also, the device's performance can be a disadvantage. Since they are older models, they may not be fully compatible with the latest apps or OS updates, and operations might feel slow. They may not be suitable for uses requiring high processing power, such as gaming or video editing.

Finally, there's the short device warranty. New smartphones typically come with a manufacturer's warranty, but for used smartphones, the warranty period may be shorter or there may be no warranty at all. It's necessary to consider the risk of having to pay for repairs yourself if a defect occurs.

At PRODIG, to ensure customers can purchase used smartphones with confidence, we have established our own strict inspection standards and clearly display the product condition in four ranks from S to C.

• S Rank: New, unopened item. 
  
• A Rank: Very good condition. Minor scratches or signs of use, but generally clean.
  
• B Rank: Good condition. Scratches and small dents from general use, but no operational issues.
  
• C Rank: Fair condition. Visible scratches or paint peeling, but no impact on functionality.

By clearly disclosing the product's condition in this way, we create an environment where customers can purchase with confidence and satisfaction. We also offer a reliable warranty service for unforeseen defects, so please consider us even if you are hesitant about used items.

How to Choose a Small Used Smartphone You Won't Regret

Check Battery Condition

When purchasing a used smartphone, the most important thing is to check the battery condition. The battery is the lifeline of a smartphone, and if it's significantly degraded, it might need charging multiple times a day. This can be a major source of stress, especially for those who frequently use their phone outdoors.

For iPhones, you can check the "Maximum Capacity" by going to Settings > Battery > "Battery Health & Charging". If this maximum capacity is 80% or more, it can be considered in relatively good condition. For Android smartphones, the checking method varies by model, but many models offer apps that provide similar information. It is crucial to check whether the maximum battery capacity is clearly stated on the retailer's website before purchasing.

At PRODIG, to help customers choose used smartphones with peace of mind, we list the maximum battery capacity on our sales pages. This allows you to understand the battery's condition before purchase and make a well-informed decision.

Thoroughly Check for Scratches and Operation

The external appearance of a used smartphone is an important factor in judging the product's condition. Prominent scratches, screen cracks, or camera lens scratches can significantly detract from the user experience. Furthermore, beyond the appearance, it's crucial to check the operation of various buttons, speakers, microphones, cameras, fingerprint authentication, and facial recognition. If these do not function correctly, you won't be able to enjoy a comfortable smartphone life.

At PRODIG, we apply our own strict inspection system to all products. Our expert staff carefully inspect each device, checking not only the external condition but also over 20 functional items. After confirming that there are no operational defects, we grade the product condition in four ranks, from S to C. This thorough quality control ensures that customers can choose used smartphones with confidence. In the unlikely event that a defect is found after purchase, please be assured that we offer returns and exchanges.

Consider the Balance Between Purpose of Use and Specifications

When choosing a small used smartphone, the most important thing is to clarify "what you will use it for." For example, if your main use is "browsing social media and websites, and mobile payments," you don't necessarily need a high-performance CPU or large amount of RAM. However, if you want to "comfortably play the latest 3D games" or "perform high-quality video editing," then a high-performance CPU and sufficient RAM are essential.

Also, "camera performance" is an important point. If you only enjoy taking everyday photos, most models will suffice. However, if you want to take higher-quality photos and videos, you'll need to choose a model with a dual or triple camera, or one that supports wide-angle or telephoto lenses.

The appeal of used smartphones is that you can get high-spec models that might otherwise be out of reach at an affordable price. However, if you demand excessive specifications, the price will also increase, diminishing the advantage of buying used. By clarifying your purpose of use and choosing a model with specifications that match it, you can make the most cost-effective choice. PRODIG offers a wide range of used smartphones across various price points and specifications, so you're sure to find a model that fits your needs.

Choose a Reputable Shop

When buying a used smartphone, one of the most important things is "where you buy it from." On flea market apps and auction sites, due to transactions between individuals, the product condition and warranty are often unclear, and there's a significant risk of encountering trouble.

On the other hand, purchasing from a reputable specialized shop like PRODIG can significantly reduce such risks.

Characteristics of a reputable shop:

• Strict unique inspection standards: Thorough operational checks and external examinations.

• Clear display of product condition: Detailed disclosure of scratches, maximum battery capacity, etc.

• Reliable warranty service: A warranty system to address any defects after purchase.

• Clear return and exchange policy: Clear rules for returns and exchanges in case of any issues after purchase.

PRODIG has a complete system in place to ensure that customers can purchase used smartphones with peace of mind. Please see here for more details on our peace of mind warranty and return policy.
