Apple Releases Software Update for iPhone 5s, 13 Years After Launch
TL;DR: Apple has released a surprise software update (iOS 12.5.8) for the 13-year-old iPhone 5s and iPhone 6. The update fixes critical digital certificates set to expire in January 2027, ensuring that essential services like iMessage, FaceTime, and device activation continue to function well into the future.
In a move that defies standard industry lifecycles, Apple has released a new software update for the iPhone 5s, a device that first hit the market way back in September 2013, when Frozen was still new and “selfie” had just been added to the dictionary.
The update, versioned as iOS 12.5.8, was released yesterday alongside the company’s modern operating system updates, including iOS 26.2.1. It is available for both the iPhone 5s and the 12-year-old iPhone 6, ensuring these vintage devices remain functional well into the future.
Keeping Critical Services Alive
While the update does not introduce new features, it provides a critical fix to ensure the longevity of the hardware. According to Apple’s release notes, iOS 12.5.8 extends the digital certificates required for essential services such as iMessage, FaceTime, and device activation.
Without this patch, these key functions were scheduled to stop working after January 2027 due to certificate expiration. By pushing this update, Apple ensures that users still relying on these older devices can continue to activate them and use communication services without interruption.
Unprecedented Support Window
This release marks a significant extension of support. Before this, the iPhone 5s and iPhone 6 last received a software update in January 2023 for security fixes.
While Apple publicly commits to a minimum of five years of security updates, the company frequently exceeds this timeline. In addition to the iPhone 5s and 6, the 11-year-old iPhone 6s also received attention yesterday. That device was updated to iOS 15.8.6, receiving the same certificate extensions to keep it operational.
This level of long-term support stands in stark contrast to the broader smartphone market, where devices are often considered obsolete after five to seven years.
