iPhone 5s Receives Software Update 13 Years After Launch

Apple has surprised long-time users by releasing a new software update for the iPhone 5s, more than 13 years after the device first hit the market. The update, iOS 12.5.8, ensures that key features like iMessage, FaceTime, and device activation continue to work well into 2027, offering extended functionality for devices most would have considered obsolete.

This move highlights Apple’s commitment to longevity, showing that older iPhones can remain secure and usable far longer than many expect. Users still relying on an iPhone 5s or iPhone 6 now have reassurance that their devices are not yet left behind.

What the iOS 12.5.8 Update Includes

The iOS 12.5.8 update is primarily focused on extending critical certificates for older devices. According to Apple, this ensures that features tied to device security—like iMessage, FaceTime, and activation—will remain functional after January 2027.

Previously, these certificate-limited features risked stopping entirely when the old certificates expired. With the new update, both the iPhone 5s and iPhone 6 will maintain core functionality, preventing disruptions for users who rely on these devices for day-to-day communication.

This update follows Apple’s trend of long-term support for older devices, even beyond its standard five-year security update window.

How Long Apple Supports Older iPhones

Apple officially promises at least five years of software updates and security fixes for every iPhone from its launch. However, the company frequently extends support for older devices, particularly for security patches and crucial feature maintenance.

For instance, the iPhone 6s, launched 11 years ago, received a security update in September 2025 with iOS 15.8.5. Just this week, it received another minor update, iOS 15.8.6, adding the same certificate extension as the iPhone 5s. This ongoing support reassures users that older devices aren’t immediately rendered obsolete once they fall out of regular software updates.

Apple’s approach ensures that millions of older iPhone users worldwide continue to have a functional and secure device, even as newer models dominate the market.

Why This Update Matters for iPhone 5s Users

For many users, the iPhone 5s represents a reliable, familiar device that they may not want to replace. The iOS 12.5.8 update ensures that this device remains practical for everyday use, even in 2026 and beyond.

Extending certificate validity is especially important for communication apps like iMessage and FaceTime, which are integral to Apple’s ecosystem. Without this update, users could face interruptions in messaging, video calls, or even activation of apps on their device.

This update also highlights Apple’s unique commitment to sustainability and device longevity, reducing e-waste by keeping older devices functional for longer periods.

What Users Should Do Next

iPhone 5s and iPhone 6 owners should install iOS 12.5.8 as soon as possible to ensure uninterrupted access to core features. The update can be installed via the standard software update process in Settings > General > Software Update.

By staying up to date, users not only maintain device functionality but also benefit from Apple’s ongoing security patches, keeping personal data protected even on older hardware.

Apple’s release of iOS 12.5.8 for the iPhone 5s and iPhone 6 proves that age doesn’t necessarily mean obsolescence. With key features extended well into 2027, these devices remain viable options for millions of users, reinforcing Apple’s reputation for long-term support and reliability. For anyone still using an iPhone 5s, this update ensures that your trusted device can keep running smoothly for years to come.
