Why is my battery life draining fast on my 6s Plus?

Try and get it replaced at an Apple Store if you can! My first 6S Plus had very average battery life.. I complained, they swapped it out for me (he said it was a one time exception... so not sure if itll work for you) and the new phone definitely had better battery life! Can get through the day with it pretty well!
