Apple has officially rolled out iOS 15.8.7, a new update designed specifically for older iPhones and iPads that can no longer upgrade to newer versions of iOS.
While the update does not introduce new features, it delivers important security fixes aimed at protecting legacy Apple devices from recently discovered vulnerabilities.
Here are five key things to know about iOS 15.8.7.
1. The Update Focuses Entirely on Security Fixes
Unlike major system upgrades, iOS 15.8.7 does not include new features or design changes.
Instead, the update addresses several vulnerabilities affecting:
-
the system kernel
-
the WebKit browser engine
WebKit powers Safari and many apps that display web content. If exploited, attackers could potentially execute malicious code through a specially crafted website.

2. Older iPhones Remain a Target for Security Exploits
Security researchers recently identified an exploit toolkit known as “Coruna”, which chains together multiple vulnerabilities to gain deeper access to iOS devices.
If successful, attackers could potentially:
-
access private files
-
extract saved passwords
-
read messages and emails
-
gain elevated system privileges
By releasing iOS 15.8.7, Apple patched these vulnerabilities to protect users who still rely on older hardware.
3. Supported Devices Include Several Classic iPhones
The update is available for older Apple devices that cannot upgrade beyond iOS 15.
iPhone models
-
iPhone 6s
-
iPhone 6s Plus
-
iPhone 7
-
iPhone 7 Plus
-
iPhone SE
Other devices
-
iPad Air 2
-
iPad mini 4
-

4. Apple Is Still Supporting Devices Nearly a Decade Old
One of the reasons Apple devices retain their value is the company’s long software support cycle.
Some of the devices receiving iOS 15.8.7 were originally released in 2015 and 2016, meaning they are still receiving security patches almost 10 years later.
5. How to Download the Update
Users can install the update directly on their device:
-
Open Settings
-
Tap General
-
Select Software Update
-
Download iOS 15.8.7
Apple recommends updating while connected to Wi-Fi and ensuring the device has at least 50% battery.

Should You Update?
Yes. Even though iOS 15.8.7 does not include new features, it is an important security update.
Older devices are often targeted by malware because they run outdated systems. Installing the latest available patch significantly reduces security risks.
Final Takeaway
The release of iOS 15.8.7 highlights Apple’s ongoing effort to keep older devices secure, even years after their original launch.
If you still use an older iPhone such as the iPhone 6s, iPhone 7, or first-generation iPhone SE, updating to iOS 15.8.7 is the best way to ensure your device remains protected from modern threats.
