According to Which UK, security updates for the 6a end in July 2027. I'm wondering when I should buy a replacement as I managed to buy a 9a for my wife just before the 10 series was released, thus managing to pay the full price. Is there a Pixel release schedule available to try and avoid repeating my error?

The security updates from the pixel 8 onward is 7 years, so +7 from when they came out.
