"The latest iPhone 17 is too expensive, but I'm worried about models that are too old."
For those facing this dilemma, the iPhone 16, which has been on the market for some time and whose price has become more reasonable, is a very well-balanced option. Its performance is still at a current level, boasting specs more than sufficient for daily use, including Apple Intelligence support, camera performance, and battery life. However, if you don't fully grasp the differences from the iPhone 17 and the precautions for buying a used one, you might regret it, finding that it "wasn't what I expected."

This article carefully explains the features, pros and cons of the previous-generation iPhone 16, its differences from the iPhone 17 and iPhone 15/14, and an estimate of how many years it can be used.
We aim to provide content that helps those considering a previous-generation iPhone 16 make a clear decision based on three pillars: "peace of mind, affordability, and practicality."

Conclusion: The previous-generation iPhone 16 is "quite viable" if cost-performance is a priority.

First, to conclude, unless you absolutely need the latest flagship, the previous-generation iPhone 16 remains a very strong option, even in December 2025. With the release of the iPhone 17, prices for the 16 series have been gradually decreasing in both new and used markets. Especially for used A-grade items, it offers a balance of "high-end performance at a mid-range price."

The iPhone 16 features improved chip performance, enhanced battery life, and better camera capabilities compared to previous models. Furthermore, it supports Apple Intelligence, Apple's suite of AI features, making it a series that becomes more convenient the longer you use it. On the other hand, the iPhone 17 introduces display, camera, and network enhancements, catering to those who prioritize "the absolute latest" or "the best possible camera."

In other words, the previous-generation iPhone 16 is perfect for those who "want a device that will last a long time while keeping costs down" or "want a cost-effective iPhone, even if it's one generation behind the latest." Conversely, if you "won't settle for anything less than top-tier camera and display performance" or "want the absolute best specs for years to come," considering the iPhone 17 series would lead to greater satisfaction.

When choosing an older model, it's crucial to calmly assess "how much performance I actually need for my usage." This article will systematically organize the information needed to make that judgment.

Who should choose the previous-generation iPhone 16?

The previous-generation iPhone 16 is a good fit for people like this:

• Currently using an iPhone 11-14 and looking to upgrade soon.
  
  

• Mainly uses SNS, watches videos, browses the web, and plays light games.
  
  

• The camera is "good enough if it takes decent pictures," but wants some quality for low light and portraits.
  
  

• Wants to keep monthly phone bills and one-time payment costs as low as possible.
  
  

• Is okay with a used phone, but wants "warranty," "inspection," and "battery condition" to be thoroughly checked.
  
  

If these points apply to you, you'll likely experience high satisfaction with the previous-generation iPhone 16, even without choosing the latest iPhone 17. Especially in the used market, A-grade iPhone 16s can be found for around 100,000 yen, making it an attractive option for users who "want to save money without compromising on specs."

PRODIG offers a wide range of used iPhones, including the iPhone 16 series, making it easier to compare options like "how does it compare to the iPhone 15 or 14" or "which model fits my budget."

Who should choose the iPhone 17?

On the other hand, there are also people who should choose the latest iPhone 17 instead of the previous-generation iPhone 16.

• Has a strongこだわり (obsession/preference) for camera performance and wants to use even slightly newer generation sensors and processing engines.
  
  

• Values "the latest comfort" such as ProMotion display and new Wi-Fi chips.
  
  

• Wants to use the top-tier specs for as long as possible, looking ahead 3-5 years.
  
  

• Prioritizes the desire to own and the satisfaction of having "the latest" over price.
  
  

The iPhone 17 series, with its A19 chip, high refresh rate display, and redesigned camera configuration, takes a step forward in terms of "everyday smoothness" and "low-light shooting capabilities." If the price difference with the previous-generation iPhone 16 is acceptable, then choosing "the 17 if you're going to buy one anyway" is a perfectly rational decision.

What is the previous-generation iPhone 16? Lineup and spec overview.

Here, we'll briefly organize "what models are in the iPhone 16 series" and "what is the positioning of each model." Even though they are previous generation, the 16 series has a wide lineup, from the 'e' model to the Pro Max, so it's important to know "which one is right for you."

iPhone 16 Series Models and Sizes

The iPhone 16 series primarily consists of the following configurations:

While size and weight vary slightly by model, the 16 series as a whole tends to be slightly larger and heavier compared to the iPhone 12-15. In return, screen visibility and battery life have improved, which actually benefits usage scenarios like "watching videos during commute" or "playing games for extended periods."

It is recommended to decide "which model suits you" based on the balance of screen size, weight, and budget. For example, if you have small hands or prioritize one-handed operation, consider the 16e/16. If you prioritize video viewing or gaming, the Plus/Pro Max would be better. Narrowing down your choices in this way can help avoid disappointment.

Performance, Camera, and Battery Features

From a specification perspective, the iPhone 16 series' key points are not only improved chip performance but also enhanced camera and battery capabilities. Even standard models are equipped with high-performance chips, ensuring smooth operation for daily use, as well as demanding games and video editing apps. Pro models feature even more powerful chips and ProMotion displays, providing significantly smoother scrolling and animations.

Regarding cameras, the entire 16 series has evolved in low-light performance and image stabilization, making it easier to capture clearer photos in challenging situations like "night-outs," "pets indoors," and "live concerts." Especially the Pro/Pro Max models include a telephoto lens, significantly improving the quality of zoomed shots.

Battery capacity has increased in line with larger screens and the inclusion of AI features, with many users reporting that the "battery life is noticeably better than my previous iPhone, lasting a full day." For those who spend a lot of time outside from morning till night, or who prefer not to carry a mobile battery, the 16 series is a reliable companion.

iPhone 16 vs. iPhone 17: Which one should you choose?

When considering the previous-generation iPhone 16, many people are curious about "the difference with the iPhone 17." Here, we will briefly summarize the price, performance, and features, and explain "who is suitable for the 16" and "who is suitable for the 17."

Differences in price, campaigns, and effective burden

Looking at new prices alone, the iPhone 17 is generally priced tens of thousands of yen higher than the iPhone 16. On the other hand, in the used market, the price of the iPhone 16 is gradually decreasing, with A-grade units starting to settle around 100,000 yen.

Especially at the time of a model change,

• Carrier clearance sales
  
  

• Lump-sum discounts on older models
  
  

• Price adjustments at used phone shops
  
  

can combine to create a significant difference in the effective cost between a "new iPhone 17" and a "used iPhone 16."

As a budget guideline:

• "I want to keep the upfront payment as low as possible" → Used iPhone 16
  
  

• "I'll pay in installments, so the total amount doesn't matter much" → iPhone 17
  
  

This is one way to differentiate. With PRODIG, you can check a wide range of stock, including not only used iPhone 16s but also iPhone 15s and 14s, making it easier to find "an option to save even more."

Differences in Apple Intelligence and New Features

The major differences between the iPhone 16 and 17 series lie in Apple Intelligence and the "fine-tuning" of camera and network features. Apple Intelligence itself is available on iPhone 15 Pro models and later (including iPhone 16 and beyond), so from the perspective of "wanting to use AI features," the previous-generation iPhone 16 already meets the requirements.

The iPhone 17 features improved camera sensors, display, and Wi-Fi chip, which can lead to benefits such as "even less noise in low-light photography" and "more stable and faster Wi-Fi communication." However, these are differences that are "noticeable when compared side-by-side," and the iPhone 16 does not suddenly become inferior.

For everyday use such as messaging, social media, video viewing, and web browsing, the 16 series offers more than enough performance. Except for some heavy-duty uses like "professional photo/video production" or "playing the latest games at maximum settings," the perceived difference with a previous-generation iPhone 16 is often not significant.

How many years of use and support period to expect

Many people worry, "If I buy an older model, will OS updates stop soon?" Based on past trends, iPhones typically receive major OS updates for 5-6 years after release, and security updates often continue for even longer.

The iPhone 16 is positioned as an Apple Intelligence-compatible generation, and is expected to be supported for a long time in terms of OS updates. If your need is to "use it reliably for the next 3-4 years," then the older 16 series is a perfectly realistic option.

Of course, batteries are consumables, so you might need to consider replacing them after 2-3 years of use, but a battery replacement can extend the device's lifespan even further. PRODIG handles used iPhones that have been inspected for battery condition, making it easier to meet the needs of those who "want to choose a unit with minimal battery wear."

4 Ways to Get a Great Deal on a Previous-Generation iPhone 16

When aiming for a previous-generation iPhone 16, "where you buy it" can significantly change the total cost and your peace of mind. Here, we'll generally outline four routes and explain the pros and cons of each.

If you're aiming for a new device at an Apple Store or carrier

First, let's consider purchasing a new iPhone 16 from an Apple Store or carrier. Even after the iPhone 17 is released, the 16 series may continue to be sold as an "older model" for some time, and prices may be reduced during that period.

Advantages

• Completely new, allowing for longer use, including the battery.
  
  

• Comes with a full manufacturer's warranty.
  
  

• Can utilize carrier installment plans, residual value plans, etc.
  
  

Disadvantages

• Higher price compared to used.
  
  

• Once stock runs out, it becomes suddenly difficult to acquire.
  
  

• There might be cases where "you could have bought the 17 for a little extra."
  
  

Especially with carriers, it's common for them to offer significant discount campaigns on older models, and you might see advertisements for "effectively 1 yen with certain conditions." However, since long-term contract plans are sometimes bundled, it's crucial to calmly check "how much you will pay in total."

Benefits of Buying a Previous-Generation iPhone 16 from a Used Shop

If you prioritize cost-performance and are looking for a previous-generation iPhone 16, purchasing from a used shop is an indispensable option. At specialized used shops like PRODIG,

• Pre-shipment functional checks and cleaning are performed.
  
  

• Battery maximum capacity and exterior condition ranks are displayed.
  
  

• Warranty and return policies are clearly stated.
  
  

These measures are in place to offer "used iPhones you can start using with peace of mind." This makes it easier to strike a balance between peace of mind and price for those who find "flea markets and auctions unsettling but are attracted by the low prices of used items."

Additionally, if you're wondering, "I'm interested in the 16, but maybe the 15 or 14 is enough," the advantage is that you can compare series across the same website.

• View PRODIG's used iPhone 15 series lineup here:

By comparing multiple series, you can find the "sweet spot between price difference and performance difference," making it easier to find the optimal device for you.

Risks when buying from flea market apps or auctions

There are also cases of purchasing previous-generation iPhone 16s through peer-to-peer transactions on flea market apps or auction sites. Price-wise, they are often listed cheaper than in shops, and there's a chance to find a good deal.

However, there are also numerous risks.

• It's difficult to ascertain battery condition and internal degradation.
  
  

• Risk of red-locked phones (network restricted) or modified devices.
  
  

• Returns/exchanges may be difficult even with initial defects.
  
  

• Cannot completely rule out the risk of counterfeits or stolen goods.
  
  

Considering these concerns, it's honestly difficult to actively recommend this option to anyone other than those who are "aiming for the absolute lowest price." Especially if you plan to use it as your main device for several years, it would be safer overall to choose a used shop with inspection and warranty, even if it means a slight price difference.

Benefits of Choosing a Previous-Generation iPhone 16 at PRODIG

PRODIG, as a specialized retailer and buyer of used smartphones and tablets, focuses on quality control and after-sales support. Here, we will outline the specific benefits of choosing a previous-generation iPhone 16 from us.

"Peace of Mind" Factors: Inspection, Data Erasure, Warranty

When buying a used iPhone, many people worry, "Will it really work properly?" or "Is there any data left from the previous owner?" At PRODIG,

• Data erasure using specialized tools
  
  

• Operation checks of various functions (calls, camera, buttons, speakers, etc.)
  
  

• Cleaning and exterior checks
  
  

• Red-locked phone warranty and a certain period of operation warranty
  
  

Through these processes, we provide "used iPhones that you can start using with peace of mind."

Furthermore, even in the unlikely event of a defect, exchange services are available based on warranty regulations, minimizing risks such as "what if it breaks a few days after I receive it?" Compared to taking on the risks of private sales yourself, it is well worth considering this "peace of mind premium," even if the price is slightly higher.

Understanding condition ranks and price differences

PRODIG displays product conditions by rank. The general guidelines for typical ranks are as follows:

• S Rank: New, unopened product
  
  

• A Rank: Very good condition. Very minor scratches or signs of use, but generally clean.
  
  

• B Rank: Good condition. Shows scratches or small dents from general use, but no functional issues.
  
  

• C Rank: Fair condition. Visible scratches or paint peeling, but no impact on functionality.
  
  

Even for the same iPhone 16, the price can vary significantly depending on the condition rank. If you prioritize price and don't mind some cosmetic scratches, choosing a B or C rank can lead to considerable savings. On the other hand, if it's for a gift or frequent client interaction at work, opting for an A rank or higher will result in greater satisfaction.

The previous-generation iPhone 16 already boasts a high level of performance, making it advantageous to choose a lower rank to reduce the price, prioritizing "substance over appearance." Whether to aim for a like-new S rank or a cheaper B or C rank with some scratches depends on your budget and preferences.

Choose while comparing with other series

If you're hesitating, wondering "Is the 16 really right for me?" or "Is the 15 or 14 good enough?", it's recommended to compare across series. At PRODIG,

Collection pages are provided for each series.

Comparing prices for similar capacities and condition ranks across different series makes it easier to decide, for example, "If for just a few thousand yen more I can get a newer generation 16, I'll go with that," or "If budget is a priority, the 15 is perfectly sufficient." Especially if you prioritize Apple Intelligence support and camera performance, choosing the 16 series makes a lot of sense, and you'll likely feel you got your "money's worth" the longer you use it.

Steps to Trade In Your Current iPhone for a Previous-Generation 16

To get an even better deal on a previous-generation iPhone 16, it's effective to "sell your current iPhone and use that money as capital for purchasing a new device." Here, we'll outline the process of switching devices, making it easy to imagine how to utilize PRODIG's in-store trade-in service.

3 Tips for Selling at a Higher Price

To maximize your trade-in value, it's important to consider the following points:

1. Include as many accessories and original packaging as possible.
   The more complete the accessories—such as the box, cables, and original adapter—the more positively it will be evaluated.
   
   

2. Keep the exterior as clean as possible.
   Simply wiping off fingerprints and dirt can change the impression. While deep scratches cannot be removed, conveying a sense of "it was used with care" will improve the assessment.
   
   

3. Complete initialization and deactivation of Activation Lock beforehand.
   Signing out of your Apple ID and turning off "Find My iPhone" can be done in-store, but completing them beforehand will expedite the assessment process.
   
   

PRODIG's trade-in website allows you to check estimated trade-in prices, making it easier to grasp "roughly how much my current iPhone will sell for" in advance and plan your budget accordingly.

In-store trade-in process and precautions

PRODIG offers a buyback service for used smartphones and tablets at our Akihabara store. The basic process is as follows:

1. Bring your device and identification documents to the store.
   
   

2. Our staff will perform function and appearance checks, then provide an appraisal value on the spot.
   
   

3. If you agree to the price, you will be paid in cash (or by your specified method) on the spot.
   
   

Since it's an in-store buyback, you can sell your device and get cash on the same day, without worrying about shipping hassles or transportation issues. This makes it easy to, for example, "buy a used iPhone 16 on the spot and transfer your data right away," allowing you to "sell → buy → set up" all in one day on your holiday.

When upgrading, it's a good idea to consider "what condition rank and capacity iPhone 16 you can afford" by combining the buyback amount with your existing budget.

Finally

For users who find the latest flagship models too expensive but want to avoid overly old models, the older-generation iPhone 16 is a well-balanced choice. With Apple Intelligence support, high processing power, and improved camera and battery performance, it's capable of handling daily use and even somewhat demanding tasks.

However, it's crucial to correctly understand the price and feature differences between the iPhone 16 and iPhone 17 and consider whether "the 16 is truly sufficient for your usage" or "the 17 is worth choosing." Just because it's an older model doesn't automatically mean it's a good deal; satisfaction can vary greatly depending on "which model, which condition rank, and where you buy it from."

By utilizing PRODIG, a specialized used goods store, you can compare a wide range of devices from the iPhone 12 to 17 series, including inspected and warranted used iPhone 16 series models, to find the best one for you.

Furthermore, if you sell your current iPhone through PRODIG's in-store buyback, upgrading becomes a more realistic option by reducing your net out-of-pocket expense.

Instead of being fixated on "the latest," consider the older-generation iPhone 16 as a positive option, focusing on "specs that fit your usage" and "reliable quality." You're sure to find a device that offers a satisfying balance of price and performance.
