When Does the iPhone 13 Series Software Support End?

The iPhone 13 series, released in the fall of 2021, has become a “golden mean” for many users due to its A15 Bionic chip power, improved battery life, and the debut of the ProMotion 120 Hz display in the Pro models. As we are now in the spring of 2026, this series is approaching five and a half years old. In the tech world, this is a significant age, making the question of software “lifespan” critical when planning your next purchase or assessing the resale value of the device.
In this article, we will analyze Apple’s historical patterns, the technical potential of the A15 Bionic, and provide an accurate forecast of when your iPhone 13 will receive its last iOS update.

1. Apple’s Support Standard: Historical Context

Apple is known as the manufacturer that provides the longest software support in the smartphone market. Although the company never announces official “expiration dates” in advance, trends are clear.

Based on academic analyses of consumer behavior and technology lifecycle studies (e.g., M. Castells, 2022), Apple has recently been striving to extend the lifespan of devices to 6–8 years to promote sustainability and retain users in its ecosystem, where profits are derived from services (Apple Music, iCloud, Apple TV+).

2. Technical Barrier: A15 Bionic and RAM Impact

Software support depends not on the device’s aesthetics but on its SoC (System on a Chip) capabilities. The iPhone 13 series uses the A15 Bionic processor, which is highly capable even by 2026 standards.

NPU (Neural Processing Unit) Importance

Modern iOS versions (from iOS 18 onwards) increasingly rely on On-device AI (artificial intelligence on the device). The iPhone 13 features a 16-core Neural Engine capable of performing 15.8 trillion operations per second. This is a key factor that will allow this model to support future operating systems that require real-time video and speech processing.

RAM Limitation

One of the few weaknesses of the iPhone 13 is its RAM (random access memory):

• iPhone 13 / 13 mini: 4 GB RAM.
• iPhone 13 Pro / 13 Pro Max: 6 GB RAM.

Academic studies on software optimization indicate that the “weight” of operating systems grows by about 10–15% each year. It is likely that the iPhone 13 Pro models, due to the additional 2 GB of RAM, may receive one more iOS version than the standard models, although historically, Apple tends to “disconnect” the entire series line at once.

3. Accurate Forecast: Key Dates

Based on the current context of 2026 (when the iPhone 13 is successfully running the latest iOS 19 version), we can outline a future roadmap:

• iOS 20 (Fall 2026): Almost guaranteed support. The iPhone 13 will still be powerful enough for all core functions.
• iOS 21 (Fall 2027): High likelihood that this will be the last major operating system for this series. The device will be 6 years old.
• iOS 22 (Fall 2028): It is likely that the iPhone 13 (especially the base models with 4 GB RAM) will no longer be able to effectively run the processes of this version.

Verdict: Major software updates for the iPhone 13 series are likely to end in the fall of 2027 with the iOS 21 version.

4. What Happens After the “End”? (Legacy Support)

Users often mistakenly believe that without the latest iOS version, the phone becomes unusable. This is a myth.

Security Patches

Apple implements a Legacy Support policy. Even if you can no longer download the latest iOS version, devices still receive critical security patches (Security Updates) for another 2–3 years. This means that your iPhone 13 will be safe to use for banking transactions and other sensitive actions until 2029–2030.

App Compatibility

App developers (Third-party developers) typically support 2–3 older iOS versions. So even if your phone does not have the latest system in 2028, apps like Facebook, Instagram, or YouTube will work seamlessly for at least a couple more years.

5. Summary: Is It Worth Keeping in 2026?

If you are currently using an iPhone 13, it is technically still in the “golden mean” zone. However, if you plan to buy it as a used device:

• Buying in 2026, you will have ~2 years of full support and another ~4 years of safe usage.
• Pay attention to Battery Health – lithium-ion batteries degrade over 5 years, so an aging battery after iOS updates may not be able to sustain higher system energy demands.
