The iPhone is an essential tool that plays an active role in all aspects of daily life, not only as a means of communication for calls and messages, but also for taking photos and videos, using social media, cashless payments, and work apps. However, if you use the same device for many years, it's not uncommon to experience issues such as faster battery drain, apps becoming unusable, or sudden malfunctions.

"Can my current iPhone still be used?" "Is it time to replace it?"

For those of you with such questions, this article, written by PRODIG, an expert in used smartphones, will thoroughly explain the estimated lifespan of an iPhone, how to determine the right time to replace it, and cost-effective purchasing methods. By reading this article, you will gain a clear understanding of "how much longer your iPhone can be used" and be able to make a replacement without regrets.

What Determines an iPhone's Lifespan? Two Important Points Explained

The lifespan of an iPhone is not solely determined by whether the device physically breaks down. Two key periods, OS (iOS) updates provided by Apple and official repair support, significantly influence how long an iPhone can be used safely and comfortably. These two points can be said to determine the practical lifespan of an iPhone.

In particular, if OS updates are no longer available, security risks increase and the latest apps may become unusable, which can cause significant inconvenience in daily life.

1. iOS Update Support Period

Apple releases new iOS versions every autumn, adding new features, improving existing ones, and applying critical security patches. These updates are broadly provided for iPhones ranging from the latest models to several generations older, but they don't last forever. Generally, after approximately 6 to 7 years from an iPhone's release, that model tends to be excluded from new iOS updates.

The main problems that can occur with an iPhone whose OS updates have ended are as follows:

• Increased Security Risks: Even if new security vulnerabilities are discovered, no patches will be provided, increasing the risk of virus infection and unauthorized access. This can lead to serious situations such as personal information leakage.

• Restrictions on Using Latest Apps and Services: Many app developers optimize their apps for the latest iOS. Therefore, once OS updates end, you may not be able to install new apps or use the latest versions of existing apps.

• Incompatibility with Banking Apps and Payment Services: Banks and cashless payment services, which prioritize security, may stop supporting devices with outdated operating systems. This directly causes inconvenience in daily life.

Thus, the OS update period is one of the most important factors for continued safe use of an iPhone.

2. Repair Support Period

Apple also sets clear criteria for product repair support periods. Products that have been discontinued for 5 to under 7 years are classified as "vintage products," and those discontinued for 7 years or more are classified as "obsolete products."

• Vintage Products: Official Apple repairs are possible if the necessary parts are in stock. However, parts availability is not guaranteed, so repairs may not be possible even if requested.

• Obsolete Products: Official Apple repair support is completely terminated. All hardware repairs, including battery replacement, become unavailable.

When repair support ends, even if a malfunction or battery degradation occurs, Apple will not be able to provide official support. At this point, the iPhone can be said to have reached its physical end of life.

iPhone Lifespan Estimates by Model (Latest to Past Models)

The estimated end of OS support and repair support for major iPhone models are as follows. These estimates are based on past trends, and the actual end dates are subject to Apple's official announcements. Please use this as a reference.

4 Clear Signs It's Time to Replace Your iPhone

Some of you may be wondering, "Can my iPhone still be used?" Here are four clear signs that your iPhone is due for a replacement. If several of these signs apply to you, it might be time to seriously consider upgrading.

1. Battery Maximum Capacity is Below 80%

An iPhone's battery gradually degrades with continued use. You can check the current battery health by going to Settings > Battery > Battery Health & Charging, and looking at the "Maximum Capacity" item. If this maximum capacity falls below 80%, Apple recommends replacing the battery.

Why is 80% the benchmark? According to information published by Apple, iPhone batteries are designed to degrade to 80% maximum capacity after 500 charge cycles, due to repeated full charging and discharging. When the maximum capacity falls below 80%, not only does the battery life shorten, but processing performance may also decline.

Specific signs of degradation

• Frequent charging is needed when out and about

• Even after a full charge in the morning, the battery is less than half by early afternoon

• The phone suddenly shuts down despite sufficient battery life

• Charging takes an unusually long time

If you experience these symptoms, it's time to consider replacement or upgrading.

2. More Than 7 Years Have Passed Since Release

As mentioned earlier, iPhones that are more than 7 years old will no longer receive OS updates or official Apple repair support. This significantly increases security risks and eliminates repair options in case of a malfunction.

In particular, iPhone 8 models and older are likely to be reaching this stage. Don't be complacent just because it's still usable; we recommend upgrading to a device that can be used safely in the latest security environment. If your iPhone is no longer covered by repair support, you can also consult PRODIG's smartphone partners for repair.

3. You're Experiencing More Performance Issues

The latest apps and operating systems tend to demand more powerful CPUs and larger amounts of memory. Therefore, if you're using an older iPhone, you'll increasingly notice performance issues in situations like these:

• Slow app launch and operation: Apps take a long time to open, or stutter during operation.

• Videos and games don't run smoothly: High-quality video playback or graphically intensive games experience frame drops.

• Dissatisfaction with photo and video quality: The quality of photos and videos looks inferior compared to the latest models.

These symptoms significantly detract from a comfortable smartphone experience. If you start to feel stress in your daily usage, it's a good time to consider upgrading to a new iPhone.

4. Device Payment is Complete

Upgrading a smartphone is a costly expense, which makes many people hesitate. However, the timing when the payment for your current device is complete is one of the smartest times to upgrade. If you are using a carrier's "device upgrade program," you may be able to significantly reduce the cost of a new model by trading in your old device. While you can continue to use a device for which payment is complete, selling it while it still retains value and switching to a new model can help you keep overall costs down.

For selling your unwanted smartphone, please also trust PRODIG. We offer buyback services at the PRODIG Akihabara store. For a smart upgrade, please try our free appraisal first.

Smartly Upgrading with a "Used iPhone" is Recommended

While the latest iPhone models are very attractive, their prices tend to rise every year, causing many people to hesitate about purchasing. Therefore, we recommend the option of a well-maintained used iPhone. While "used" might cause apprehension, if you choose a reputable specialty store, you can acquire a device of like-new quality at a great price.

3 Benefits of Choosing a Used iPhone

Used iPhones offer many advantages that new ones do not.

• Significantly lower purchase cost: Even for the latest models, and especially for older models, a used iPhone can be tens of thousands of yen cheaper than a new one. This allows you to get a high-performance model within your budget.

• Sufficient performance for your needs: For those who don't require the absolute latest performance, even a model a few generations old offers more than enough performance for everyday use.

• Wide range of choices: While new models have limited lineups, the used market offers a variety of past models. It's easier to find a device that perfectly matches your preferences in terms of design, size, and features.

• Environmentally friendly choice: Choosing a used smartphone helps reduce the consumption of new resources and electronic waste. It's a smart, eco-conscious decision.

How to Choose a Used iPhone | Checkpoints to Avoid Failure

When purchasing a used iPhone, there are several points to keep in mind to ensure a satisfactory purchase. Be sure to check the following three points in particular:

• Battery Maximum Capacity: As mentioned above, battery health affects iPhone usability. Make sure the maximum battery capacity of the device you are considering is 80% or higher.

• Red Lock Warranty Availability: A "red lock" (赤ロム) refers to a smartphone whose communication is restricted and becomes unusable due to unpaid device bills or other reasons. You can rest assured if there is a lifetime warranty in case the purchased device becomes red-locked.

• Return/Exchange Policy: In case of initial defects or discrepancies with the product description, check in advance what return and exchange policy the seller offers.

Summary: Choose "Comfortable to Use" over "Still Usable"

The lifespan of an iPhone is largely determined by its OS update support period and repair support period. After about 7 years from its release, security risks and risks in case of malfunction increase significantly, making it a good time to consider a replacement.

When signs of replacement appear, such as faster battery drain or slower operation, it's a smart choice to sell it while it still has value and switch to a new model. By considering well-maintained used iPhones as an option, in addition to new models, you can enjoy a comfortable smartphone life while keeping costs down.

PRODIG offers a wide selection of carefully chosen, high-quality used iPhones. We invite you to find the perfect device to suit your lifestyle.
