For my contribution to this anecdata the only Pixel phone I've had die is my Pixel 3 XL that started having weird charging issues and refuses to turn on and charge unless I let it completely passively drain then recharge it after that it only works for a bit, that happened after about 2 years maybe. Tried having it looked at by uBreakIFix and they had nothing. Other than that my Pixel 6 is doing great but I keep it in a case 99% of the time and don't abuse it.
