If you have an old iPhone, it is likely that you cannot continue to upgrade to newer versions of the operating system, such as iOS 15 or iOS 16. Just because they cannot be upgraded anymore, it does not mean that these devices cannot continue to be updated. Functional in many ways. And even, you may have an older version of iOS, and you can update to a newer (albeit outdated) version. Or install security patches that Apple releases from time to time for these devices.
The iOS version varies by iPhone
In this first section, we will see which iPhones have already stopped updating to iOS 16. We will also see what are the maximum supported versions for each device. We will also see if recent updates have been released in the form of security patches to cover specific security holes or vulnerabilities that could put our devices at risk. the iPhones that no longer update to iOS 16 are:
- iPhone 7
- iPhone 7 Plus
- The first generation iPhone SE
- iPhone 6S Plus
- iPhone 6s
- iPhone 6 Plus
- iPhone 6
- iPhone 5s
Although there are older iPhone models, we will focus first of all on the ones on this list, since they support relatively newer versions, and we have received updates. from security.
iOS 12 It is the maximum version supported by iPhone 5S, iPhone 6 and iPhone 6 Plus. On January 23, 2023, Apple released iOS 12.5.7 for these devices. This update covers vulnerabilities and vulnerabilities in this version of the system.
iOS 15 It is the maximum version supported by iPhone 6S, 6S Plus, 7, 7 Plus, and first generation iPhone SE. On January 23, 2023, Apple released iOS 15.7.3 and it fixes system bugs and security holes.
The difference between 32 and 64 bits
There is a very distinct difference from the iPhone 5S, which are two processors with 64-bit architecture. Until iPhone 5, A processors were running in 32-bit architecture, and the latest operating system had support iPhone 5 and iPhone 5C running iOS 10.3.3released in July 2017, which fixes security issues.
However, these two devices are the most limited in terms of functionality, since many applications are only available for 64-bit processors. And while there are developers that allow you to download older versions of their apps, others do not allow you to download such old versions for performance and security reasons.
Now that we’ve seen the iPhone 5 and 5C, the last Apple device to have a 32-bit processor, let’s see what happens with the iPhone 4S, 4, 3GS, 3, and 2G, the original iPhone. Although anecdotal, these are the latest iOS versions that are supported by these devices.
the iPhone 4S supports up to iOS 9.2. iPhone 4 supports up to iOS 7.1.2. iPhone 3GS supports up to iOS 6.1.6, which is the latest version of iOS with the old Apple look, before they made all the design changes in iOS 7. iPhone 3G supports up to iOS 4, the version released in 2010. iPhone 2G, its maximum version is iPhone OS 3.1.3, when iOS was not even iOS.
