Do banks charge to keep your money?

I'm curious, do banks actually charge customers for simply keeping their money in their accounts? It's a common misconception that banks provide a free service by storing our funds, but is there a hidden cost involved? I've heard of fees for overdrafts and maintenance, but what about just having a balance in the account? Could you clarify if there are any charges associated with keeping money in a bank account, and if so, what are they typically?
