Why own two iPhones? A complete guide to the pros, cons, and recommended models.

The practice of owning two iPhones, gaining attention recently, is for reasons such as "I want to separate my private and work use" or "I want a smartphone just for games and social media."

However, many people probably wonder, "Is it really convenient?" or "How about the cost-effectiveness?"

This article will explain the advantages and disadvantages of choosing to own two devices, key points for selection, and recommended iPhone models, along with how to buy them smartly secondhand. We'll also introduce how to choose a reliable used iPhone, so please read until the end.


Reasons Why More People Are Carrying Two iPhones

An increasing number of users are opting to carry two iPhones. Especially among working professionals in their 20s and 30s, the practice of using different smartphones for different purposes is gaining attention, and from a cost-effectiveness perspective, more people are choosing a used iPhone as their second device.

 

Want to Separate Private and Work Use

For working professionals who frequently communicate for business, separating personal and professional smartphones is a smart way to protect privacy while maintaining efficient communication. By having separate LINE accounts and contact lists, the risk of miscommunication can also be reduced.

 

Want a Dedicated Device for Entertainment/Social Media

Having a dedicated smartphone for personal entertainment, such as YouTube, Netflix, games, Instagram, or TikTok, can help conserve the main device's battery and better manage concentration.

 

Want to Save Money by Using Different Carriers

Another benefit of carrying two devices is the ability to choose different pricing plans for different uses, such as using a major carrier for the first device and a low-cost SIM for the second. This allows for optimization based on function, such as tethering for outdoor use, calls, or data communication.


Advantages and Disadvantages of Carrying Two iPhones

While carrying two devices might seem costly at first glance, operating them with practicality in mind offers many benefits. On the other hand, there are, of course, considerations to be aware of.

 

Advantages

Can Distribute Battery Consumption

Even if you consume a lot of battery watching videos, using social media, or playing games, you can rest assured with a secondary device. This helps preserve the main device's battery.

Easier Privacy Management

Contacts, history, and apps can be completely separated, making it ideal for business use.

Can Optimize Apps and Notifications by Purpose

Separating devices, for example, using one for work notifications and the other for hobbies and entertainment, can help maintain focus and reduce stress.

 

Disadvantages

Potential for Double the Cost

Since you'll incur costs for two devices and two communication plans, utilizing affordable used devices and low-cost SIM cards is key.

Increased Baggage and Management Complexity

You'll need to carry two devices, and charging and managing their loss will also be doubled.

Inconvenient Switching for Some Apps

Some apps, like LINE and certain authentication apps, have restrictions on multi-device usage, so it's important to check their specifications in advance.


Recommended iPhone Models for Your Second Device [By Use Case]

Used iPhones offer a good balance of performance and price, with many models available. When choosing a second device, select one that suits your usage style.

 

Recommended as a Sub-Device (Used, ¥10,000-¥30,000 range)

  • iPhone SE (2nd generation): Small, lightweight, easy to carry, and features Touch ID. Sufficient performance for a sub-device.

  • iPhone 8 / iPhone XR: Despite being in the low-price range, they handle LINE and map apps comfortably, making them recommended for a first sub-device.

 

For Gaming and Video Viewing (Cost-Performance Focused)

  • iPhone 11 / iPhone 12: Excellent balance of screen size and processing power, ideal for entertainment.

  • iPhone 13 mini: A superb device with a high-performance chip and compact body, combining power with portability.

 

For Camera Use and Social Media-Focused Sub-Device

  • iPhone XS / iPhone 11 Pro: Excellent night mode and portrait performance, perfect for photo and video posting.


Precautions When Choosing a Used iPhone as Your Second Device

While used smartphones offer excellent cost-effectiveness, it's important to check a few key points before purchasing.

 

Check Battery Degradation

On iOS, you can check the maximum battery capacity in settings. If it's below 80%, consider replacement.

 

Whether SIM Lock is Released

Confirm if it's SIM-free and check if it can be used with your current mobile carrier for peace of mind.

 

Presence of Red-Flag Guarantee / Operation Guarantee

It's crucial to ensure there's a red-flag guarantee, which means there's no risk of network usage restrictions.

 

At PRODIG, all products come with a permanent red-flag guarantee, are operation-checked, and cleaned. You can choose with confidence, even for your first used purchase.


To Reduce Costs, We Also Recommend Utilizing iPhone Buyback

One way to reduce the cost of purchasing a used iPhone is to sell your current smartphone. By selling devices you no longer need or older models, you can use the funds towards buying a second device.

 

Benefits of Utilizing Buyback

  • You can effectively utilize your existing assets.

  • There's a possibility of selling your device at a high price even after upgrading.

  • You can aim for immediate cash or discounts through trade-ins.

 

It might be a good idea to check the buyback price first on the PRODIG Buyback Site.


Finally

Using two iPhones can reduce daily stress and enable a more comfortable smartphone life if managed well. While there are challenges regarding cost and effort, the benefits of creating an optimized environment for each purpose are significant.

PRODIG offers a wide selection of reliable used iPhones with red-flag guarantees, and combining this with buyback can maximize cost-performance. If you're considering owning two devices, please check out PRODIG's lineup.
