android system battery usage

[Hamed]

is it normal 25% battery usage about 18 hours when i dont use the cellphone ?
Android system uses the most amount of battery. I think I need a app to know exactly which system app is using the battery. Can you guide me? thank you

I've started to see this too, that Android system use to much battery. It started 2 updates ago on my Edge 20.
I was hoping the next update would fix this, but that was not the case.
My thread:

Motorola Edge 20, low battery usage after update because of "Android system"

Since the 2nd last update, I've started to get less battery life, and I can see it's "Android system" which is using the battery. Anyone else experience this?
