Introduction & Clarification
First and foremost, it's important to clarify that no iPhone will literally stop functioning in 2024. Even older models like the iPhone 6 can still operate and perform basic tasks such as making calls, sending texts, and browsing the internet. However, Apple periodically discontinues iOS updates for older devices, meaning these models will no longer receive the latest software updates, security patches, or new features. This can have implications for performance, security, and app compatibility over time.
Understanding iOS Updates
iOS updates are crucial for ensuring that your iPhone runs smoothly and securely. These updates often include new features, bug fixes, and optimizations that enhance the user experience. Most importantly, iOS updates address security vulnerabilities, ensuring that your device is protected against the latest threats. When Apple ends iOS support for a particular model, that device will no longer receive these important updates, which can lead to performance issues and increased security risks over time.
Understanding Security Updates
Even after an iPhone stops receiving the latest iOS updates, Apple may continue to provide security updates for a limited time. These updates specifically address critical security vulnerabilities, ensuring that your device remains protected against emerging threats. However, once a device stops receiving both iOS and security updates, it becomes increasingly vulnerable, as it no longer benefits from Apple's ongoing security enhancements.
Not Upgradable to Latest iOS vs. Not Receiving Security Updates
There’s a distinction between iPhones that are no longer upgradable to the latest iOS version and those that have stopped receiving security updates.
- Not Upgradable to Latest iOS: These iPhones can still receive critical security updates but will not be able to access new features, optimizations, or apps that require the latest iOS version.
- Not Receiving Security Updates: These iPhones have reached the end of their support life cycle, meaning they no longer receive any updates from Apple, including critical security patches. This can make them more vulnerable to security threats and gradually obsolete.

Recommendations
If you own an iPhone that is no longer upgradable to the latest iOS 18 or has stopped receiving security updates, it’s advisable to consider an upgrade. While these devices can still perform basic functions, they are at greater risk of security threats and may become less compatible with new apps over time.
It’s important to note that upgrading to a newer model doesn’t necessarily mean buying the latest iPhone. Certified Used or Refurbished iPhones are excellent alternatives that offer the latest iOS support and security updates at a lower cost. These models are thoroughly tested and certified to ensure they meet high-quality standards, providing a reliable and affordable option for those looking to upgrade.
If you’re considering an upgrade, here’s a list of iPhone models that currently support the latest iOS 18:
- iPhone XS / XS Max
- iPhone XR
- iPhone 11 / 11 Pro / 11 Pro Max
- iPhone SE (2nd Gen) / SE (3rd Gen)
- iPhone 12 / 12 Mini / 12 Pro / 12 Pro Max
- iPhone 13 / 13 Mini / 13 Pro / 13 Pro Max
- iPhone 14 / 14 Plus / 14 Pro / 14 Pro Max
- iPhone 15 / 15 Plus / 15 Pro / 15 Pro Max
Although the iPhone XR is the cheapest model (around $120+) in the list above, we recommend getting an iPhone XS for only $10-$20 more. The iPhone XS has a significant hardware upgrade compared to the iPhone XR.
Used iPhone vs. Certified Used iPhone
When upgrading, it’s crucial to understand the difference between a Used iPhone and a Certified Used iPhone. A Used iPhone is typically sold as-is by an individual or reseller, often without any guarantees about its condition or functionality. These phones might have defects, wear and tear, or even hidden issues that the seller may not disclose.
On the other hand, a Certified Used iPhone is thoroughly tested, inspected, and refurbished by professionals to meet specific standards. These phones often come with warranties, ensuring that you’re getting a device that functions like new, without the risks associated with buying a regular used phone. Certified Used iPhones offer a balance between affordability and reliability, making them an excellent choice for those looking to upgrade.
