It's called spin farming, and there are videos of people that are already doing it. YouTube Curtis Stone.
And I've seen several videos about getting returns of 10% a year average, but I don't remember if it was regular savings accounts specifically. Dave Ramsey talks about this all the time.
Savings are what is left over to "play" with, that is, if you lose 50% of it in the stock market, it does not affect your life. That is what I mean by play with.
You are young, any "savings" you have, should go into a business of your own, or to buy a house to live in. But you can't go into business without first getting experience in that business without any risk to your money, by working for someone else who is in the business you want to get into. So your savings for now should go into a house you can live in.
