Apple watch battery

Hi guys

I don't use my apple watch very often and I am trying to find a way how to keep as much battery as possible, so I don't need to charge it every day even if I am not using it...

I have low power mode turned on and wifi off

But I still need to charge it every two days, because I was told it is not good for new batteries to run out of battery

What do you guys do in this situation, how to save my apple watch battery and my time?
