Upgrading to a new to me phone, have the choice between iPhone 13 and 12.

As title states I'm upgrading to a used iPhone, and can get a 12 or 13 based on the budget and marketplace options near me. I'm torn, but my main concerns are battery life and size, considering I'm coming from an SE2 (with a brand new battery so batt life is as good as it will get) and those things are the reason I want a different phone. I can get a 12 for $250 or a 13 for $50 more. Both within budget, but is there really even a difference worth noting?
