I received the email from Google notifying me of this "battery performance update" for my Pixel 4A which actually drains the battery faster, so it left me scratching my head wondering what a "performance update" is for Google.

After the update, my battery was depleted at an alarming rate. I applied for the $100 voucher but I've never heard back from Google. So I decided to bite the bullet and moved to iPhone instead. Apple might not be the best, but this was the last straw for me.
