Apple confirms that iOS 14 security updates were temporary measure

Apple confirmed that users will get security update for previous iOS release for some amount of time and then should proceed with update to iOS 15.

If you're using iOS or iPadOS 14.5 or later, you might now see the option to choose between two software update versions. This option allows you to choose between updating to the latest version of iOS or iPadOS 15 as soon as it's released, or continuing on iOS or iPadOS 14 while still getting important security updates for a period of time.

Apple Support

Currently, it is expected that users will need to upgrade to iOS 15.

iOS 15 adoption rate is slower than iOS 14 was year ago, 72% of modern devices now

Apple updates adoption numbers on App Store developer site. iOS 15 is currently on 72% of recent devices and just 63% of all compatible devices. Numbers for iPadOS are lower – 57% and 49% correspondingly.

This adoption rate is actually expected. Apple allowed users to stay on iOS 14 and receive security updates without getting the latest release.

However, it seems that now Apple is actively pushing users to update to iOS 15.

9to5Mac was able to confirm that devices running iOS 14.8 or previous versions of the operating system can no longer be updated to iOS 14.8.1. Instead, the Software Update menu only shows the iOS 15.2.1 update. Previously, iOS 15 was shown as an optional update, while users could just install iOS 14 security patches.

Survey shows that 87% of US teenagers use iPhone

Survey report shows that 87% of US teenagers use iPhone.

Both the 87% iPhone ownership and 88% intention to purchase an iPhone metrics are near record highs for our survey. We view the elevated penetration and intention are important for a maturing premium smartphone market. In addition, these trends are encouraging as the company continues to introduce new 5G iPhones, which could provide a significant product cycle refresh. We think these positive trends can also be a catalyst for further services growth as well, as the install base for Apple hardware continues to grow.
