Google’s Pixel 6 doesn’t come with five years of Android updates — only three

Google's new phones will be powered by a Google-designed chipset for the first time. This gives the company Apple-like control over the internal workings of the Pixel 6 and Pixel 6 Pro. However, if they thought that would mean that they would also receive an Apple-like amount of OS updates, the company is a little skeptical. Google's support page shows that it only promises to provide Android updates until October 2024 (via Android Police), which is three years after the release.
Google informs The Verge that users will still receive OS updates for at least three years. After which, they will commit to keeping Pixels secure and up-to date. The hardware's capabilities and requirements will determine the frequency and types of updates.

Google announced in its Tuesday keynote that Pixel 6 and Pixel 6 Pro would receive five years of security updates, two years more than the previous year! Android version updates, such as Android 11, Android 12 and so on, are another matter. Google technically says it will provide new Android versions until October 2024. However, Google has not historically fulfilled these promises.

During this time, the iPhone 6S, which has been around for six years, was updated to iOS 15.
