A repeat of smudger's epic deal here, but for Pixel 6a.
Google are being evasive about who's eligible but you can check here. I was offered a US$452 refund. People will get different offers depending on if they're in/out of warranty.
Getting the refund involves the same process of creating a Payoneer account and waiting a couple of weeks.
Battery replacement capability (instead of providing a refund) is expected in Australia soon. Individual end users will have one year from the initial software release on July 8, 2025 to register and make a choice of one of the support options, which may vary by country of purchase, location, and warranty status. After July 8, 2026, these support options will no longer be available.
I checked and ineligible :(
