Apple ceasing to offer the latest version of iOS for a mobile device doesn't mean the device becomes a mere paperweight. The company demonstrates this once again with an unusual move: a round of updates for iMessage and FaceTime and the device activation will continue to work for several more yearseven in models that are more than a decade old.
Far from the major new features of the latest iOS, these legacy versions focus on something much less flashy but essential: renew internal security certificates that were close to expiring in January 2027If Apple hadn't intervened, millions of older devices would have lost key messaging and video calling features, something especially relevant in markets like Spain and the rest of Europe, where second-hand iPhones and "battleground" models are still very much alive.
Updates for older iPhones: what Apple has actually done
In this latest wave of software, Apple has surprised everyone by releasing patches for several very old branches of its operating system. This isn't about new features or visual changes, but about keeping basic services operational. on mobile phones and tablets that many had already completely forgotten.
The list of recovered versions includes iOS 12.5.8, iOS 15.8.6, iOS 16.7.13 and iOS 18.7.4as well as their iPadOS equivalents. In parallel, the company has also distributed iOS 26.2.1 for the latest models, but the real news is for those devices that were stuck on previous versions and are now getting a second chance to stay connected.
The most striking case is that of iOS 12.5.8, designed for the iPhone 5s, the iPhone 6, and other devices from that era.We are talking about terminals presented in 2013 and 2014 that, despite being considered “vintageThey reappear in the Software Update section so many years later. Something very rare in the mobile industry.
In parallel, Apple has applied the same type of strategy to somewhat more recent generations such as those of iPhone 6s, 7, 8 and Xwhich are still very common as second-hand mobile phones, family phones or basic work devices in Spain and in much of Europe.
iOS 12.5.8: The patch that prevents iMessage and FaceTime from turning off on older iPhones
The most publicized update is, without a doubt, iOS 12.5.8Not because it makes 2013 iPhones modern, but because it acts as a silent lifeline. Its main role is extend the validity of an internal security certificate that was due to expire in January 2027 and on which functions such as iMessage, FaceTime and device activation depend.
Apple makes this clear in its release notes: The new build extends the certificate required for services like iMessage, FaceTime, and activation to continue working beyond January 2027.Without this patch, those phones might still turn on, but they would lose much of their practical use by not being able to communicate with Apple's servers or activate the device after a restore.
The following devices are receiving iOS 12.5.8, all of which are currently stuck on iOS 12 and have no option to upgrade to iOS 13 or higher:
- iPhone 5s.
- iPhone 6.
- 6 iPhone Plus.
- iPad Air (1th generation).
- iPad mini 2.
- iPad mini 3.
- iPod touch (6th generation).
In many Spanish and European homes, these devices survive as emergency mobile phones, multimedia players, home automation remotes, or telephones for children and the elderlyFor those kinds of uses, being able to continue sending iMessages, making a FaceTime call, or reactivating the device after a reset is more important than having the most modern interface.
It's also worth remembering that the iPhone 5s was launched in September 2013 and that its last major security update was in 2023. With iOS 12.5.8, it is now approaching 13 years of maintenance.a figure well above what most Android manufacturers offer, where a device of that age would have been completely out of the game for a long time.
iOS 15.8.6 and iOS 16.7.13: the iPhone 6s, 7, 8 and X are also included in the round
The renewal of certificates and security patches doesn't stop with iOS 12. Apple has also revived branches such as iOS 15 and iOS 16, which had been frozen for some time, with new versions that strengthen security and, in some cases, also ensure the continuity of key services.
On one side is iOS 15.8.6, aimed at a generation of iPhone still very visible in Spain and Europe, both in the second-hand market and in the hands of users who don't need the latest model:
- Iphone 6s.
- iPhone 6sPlus.
- iPhone SE (1rd generation, 2016).
- 7 iPhone.
- iPhone 7 Plus.
In the tablet ecosystem, the sister upgrade is iPadOS 15.8.6, available for:
- iPad Air 2.
- iPad mini (4th generation).
- iPod touch (7th generation).
In these models, Apple indicates that The priority is on security patches and vulnerability fixes.This approach aims to equate the protection of these devices, as much as possible, with that of newer versions. This reduces the risk of continuing to use them connected to the internet, even if they are no longer up-to-date with the latest features.
One step above is iOS 16.7.13Designed for the generation that pioneered the buttonless Home design and the leap to Face ID. Compatible models include:
- 8 iPhone.
- iPhone 8 Plus.
- iPhone X.
On iPad, the same branch comes with iPadOS 16.7.13 a:
- iPad (5th generation).
- 9,7-inch iPad Pro.
- iPad Pro 12,9-inch (1th generation).
iOS 18.7.4 and the rest of the patches: maintenance for those who no longer reach iOS 26
Although the news is in the older models, Apple has taken advantage of the same wave to release iOS 18.7.4, a maintenance version intended for iPhones that are stuck on iOS 18 and cannot be upgraded to iOS 26. The goal, as in the other cases, is maintain a basic level of security and compatibility without introducing major changes for the user.
The models that can install iOS 18.7.4 are:
- iPhone XS.
- iPhone XS Max
- iPhone XR.
On tablets, the corresponding update is iPadOS 18.7.4which reaches, for example, the iPad (7th generation)In all these cases, the company makes it clear that there are no major new features, but rather security fixes and stability adjustments.
Meanwhile, users of newer models receive iOS 26.2.1which, in addition to minor fixes, adds compatibility with the new second generation AirTagThat update, however, belongs to a different league and does not affect the scenario of older iPhones that want to remain functional for iMessage and FaceTime.
What exactly changes: renewed certificates and security patches
Beyond the list of models, the key to this whole movement lies in what's under the hood. In iOS 12 and iOS 15, Apple has renewed internal security certificates that were about to expire.These certificates are what allow the device to trust Apple's servers and use services like iMessage, FaceTime, or account login.
If those certificates were to expire without replacement, the effect on the user would be very clear: The affected iPhones and iPads would no longer be able to send and receive iMessages, make FaceTime video calls, or even activate the device after a restore.A mobile phone that cannot authenticate with Apple's servers is, in practice, only partially functional.
Apple seems to have learned from other cases where certificate expiration left many users stranded. Some older Google Chromecasts became unusable overnight due to an unrenewed certificate, and something similar happened with certain peripherals that depended on specific software to continue functioning.
In addition to certificates, these compilations include patches against known vulnerabilities that have been discovered in recent years. They don't make these iPhones the ideal choice for online banking or browsing particularly complex websites, but they do reduce some of the risk of continuing to connect them to the network.
It should be kept in mind that many of these devices have 1 or 2 GB of RAM, older processors, and outdated versions of SafariThis translates into a limited experience with modern websites and the inability to install many recent apps, which have become incompatible with iOS 12, 15, or 16 after a few years.
Impact in Spain and Europe: second-hand mobile phones, schools and specific uses
In the European context, and especially in countries like Spain where the refurbished and second-hand market is very important, these kinds of patches are not a minor detail. Many users still use iPhone 6s, 7, 8 or even 5s as a second mobile phone, a phone for children or a support device at workAnd keeping basic communication functions operational makes all the difference.
This is also noticeable in the professional and educational spheres. It's not uncommon. Old iPads in classrooms, small shops, POS systems, interactive kiosks, or control systems They continue to function thanks to the hardware's resilience and the software's reasonably secure operation, which requires minor adjustments. A sudden outage affecting iMessage, FaceTime, or activation would have forced users to replace their devices prematurely.
This decision also helps to reduce the gap between those who can change their mobile phone every few years and those who depend on Equipment that is over a decade old but still functionalNot everyone needs the latest camera or the brightest screen, but almost everyone appreciates being able to continue sending messages and making video calls smoothly.
There is also a direct effect on the Apple's reputation compared to other manufacturersThe company was already known for offering around five years of major iOS updates and one or two more years of security patches, something that is only now beginning to be seen in Android's high-end range with Google and Samsung. The fact that an iPhone 5s will still receive a specific patch in 2026 reinforces the idea that support doesn't simply end abruptly.
They are still useful, but with clear limits for everyday use.
The fact that these older iPhones receive updates doesn't mean they're recommended again as a primary phone for everything. The inherent limitations of hardware and app compatibility dictate how far one can go.Many popular apps have stopped working on iOS 12 or 15, and others can't even be installed from the App Store.
In practice, most of these devices are used as Emergency phones, music and podcast players, "workhorse" mobile phones, or terminals for children and the elderly They only need calls, basic messaging, and a few specific apps. In that context, an update focused on maintaining iMessage, FaceTime, and activation is more than enough.
For those who still use them as their daily mobile phone, these patches are a good opportunity to to bring everything up to date: update the system, review passwordsActivate two-step verification and exercise extreme caution with suspicious links and files.They don't make the device immune to security problems, but it's always better to have the latest patch available than to stay on a vulnerable version.
From an environmental point of view, extending the lifespan of terminals is also important. Preventing millions of iPhones and iPads from ending up in a drawer or at the recycling center prematurely It fits with the sustainability policies that the European Union wants to promote in consumer electronics, and gives users and companies some extra leeway to better plan their upgrades.
How to update your iPhone 5s, 6, 6s, 7, 8, or X so you don't lose iMessage and FaceTime
For those who still have one of these devices in operation, the installation process is simple and is done directly from the terminal itself. The OTA (via Wi-Fi) update system remains the same as in the most modern models, without needing to connect it to a computer.
The basic steps are the usual ones:
- Open the app Settings on the iPhone or iPad.
- Enter the section General.
- Click on Software update.
- Wait a few seconds for the system to check for new versions.
- If a compilation appears like iOS 12.5.8, 15.8.6, 16.7.13 or 18.7.4, touch on Download and install and follow the instructions on the screen.
During the process it is advisable Connect the device to a stable Wi-Fi network and make sure it has enough battery power.It is best to plug it into the charger to prevent it from turning off mid-installation, which could cause quite a scare.
On models that can no longer install iOS 26, the system itself will take care of it. offer the latest compatible versionwithout the user having to choose between different branches. After the update, the version number can be checked in Settings> General> Information and, if desired, activate automatic updates for future occasions.
With this rollout of patches, Apple makes it quite clear that Their idea of ​​support for iMessage, FaceTime, and activation goes beyond the commercial life of the iPhone.Older models will no longer receive groundbreaking features or redesigns, but they gain extra time to continue fulfilling their purpose as secondary phones, family devices, or basic work tools, something that in European countries with high terminal reuse can make a difference in daily life.
