I was full sure I would see battery improvements moving to pixel. Given its their platform and their chipset, I dont understand why it is worse than the midrange samsung I had.
Like way worse, I struggle to get to the end of the day on days I dont drive.
Can anyone explain or do I have an issue.


You brought a pixel. They are known to suffer in this area. The A55 had superior battery because it has midrange performance so it cannot burn much anyway. You can turn off 5G, turn on battery saver. But, you cannot do much.
Pixels offer sub flagship performance and way worse battery. Get a different smartphone next time if you want good battery life.
