How to make battery health dip slightly lower on iPhone?

How would one make the iPhones battery health go down? I find loads online about keeping the battery in good condition. But what if one wants to make it drop 1-2% more on purpose? I was thinking about putting it in the freezer for example to skew the measurement but not 100% sure what would be a good idea.
