How do i improve macbook pro battery life?

I am baffled at the array of often conflicting recommendations on this question and having just spent yet another £100 on a new battery I am determined to get the most out of it for as long as possible. The last one got me 357 cycles which some would might is pretty good - I think I could do better. Please does anyone have some sensible advice that holds water? Like is there an app / software that will help? Thank you in anticipation. 😕
