Apple Releases Surprise iOS 15 and iOS 16 Security Updates for Older iPhones and iPads
While the tech world’s attention is firmly fixed on the latest features of iOS 26, Apple has quietly rolled out iOS 15 and iOS 16 Security Updates for Older iPhones and iPads. On Wednesday, the company released iOS 15.8.7 and iOS 16.7.15, delivering essential security patches and bug fixes to iPhones and iPads that are no longer compatible with modern versions of the operating system.
This move underscores Apple’s continued commitment to supporting its aging hardware ecosystem, even years after those devices have been superseded.
What’s New in the Updates?
According to the release notes, the updates—iOS 15.8.7 (build 19H411) and iOS 16.7.15 (build 20H380) —focus exclusively on behind-the-scenes improvements. Apple has stated they contain “important bug fixes and security improvements,” but as is typical for these legacy patches, detailed release notes have not been provided.
Users should not expect to find any new front-facing features. Instead, these updates are designed to shore up device security and ensure stability for those holding onto older models.
Which Devices Are Affected?
These updates are specifically targeted at devices that cannot be upgraded to iOS 17 or later.
iOS 16.7.15 is available for:
iOS 15.8.7 is available for:
- iPhone SE (1st generation)
- iPhone 7
- iPhone 7 Plus
- iPhone 6s
- iPhone 6s Plus
On the iPad side, the corresponding iPadOS updates bring the same security enhancements to models like the iPad Air 2 and iPad mini 4, which are also limited to iPadOS 15.
How to Update Your Device
For users of these older devices, installing the update is a straightforward process and is highly recommended to maintain security.
- Open the Settings app on your iPhone or iPad.
- Tap on General.
- Select Software Update.
- If the update is available for your device, you will see the option to download and install it.
Users who have Automatic Updates enabled may find that the update has already been installed overnight without any manual intervention.
Why This Matters
In an era where software support lifespan is a key factor for consumers, Apple’s decision to patch vulnerabilities in operating systems that are several years old is significant. It provides peace of mind for users who choose not to upgrade their hardware, ensuring their devices remain protected against newly discovered threats. It also benefits the secondary market, keeping older devices safer for new users.
While iOS 26 continues to dominate the headlines with its “Liquid Glass” design and new features, this quiet update serves as a reminder that Apple hasn’t forgotten the millions of users still relying on its classic devices.
