Good Idea to Get Kindle Oasis 2?

I'm VERY eager to get a Kindle Oasis 2 but worried about the battery. Considering that it's been more than a year since it was released, should I hold on to my 25% trade-in discount until May 31, 2019 (the expiration of the discount) for a new Oasis with better battery or is the KO 2's battery not as bad as people say it is?
