Just found the deal of the century on a brand new Nexus 6p 64g!!

So I was contacted today by an awesome guy through the market place where I have a phone for sale. Ironically he wasn't enquiring about my phone but I had responded to someone saying what price range I was in for a new phone with a larger screen. I gave him my cell and we talk. He at first offered me a Pixel XL for $400 which since my other phone hadn't sold I could not buy. He happened to have three Nexus 6p phones one being brand new in box with the plastic still on it. We got to talking and I told him I'd be interested in one of his Nexus 6p which I've owned before and it has always been my favorite Android phone since I switched from Apple a little over a year ago now. I missed the one I sold but it was 32g and I wanted the 64g anyway. So he says how about $150!!! I was floored! I could not believe the price he said. I of course said yes I'll take it. So I've got a brand new in box Nexus 6p 64g on the way for $150 dollars. I am super stoked because I typically keep two devices. One smaller and one larger. The 6p will now serve as my larger device to watch movies on, browse the internet and YouTube. Basically my media phone. I know there are many reports of the battery going bad so I hope that in this case since it's new that my battery will be okay for a while. I have always thought the Nexus 6p was one of the best Android devices ever made and I've gone through just about all of them over the year and half since I swapped over from Apple. Right now I'm using an Axon 7 mini as my daily driver which has a 5.2 inch screen. I just could not believe the price he offered it to me for. What do you guys think? Will I be okay with the battery since it's new? The performance I know will be great and interface smooth. Plus I used an honor 8 for a long time and Huawei Honor has been my favorite Android company. Anyways I'm excited to be getting a Nexus 6p again. Especially at the price point for a new 64g. What exactly is going on with the battery issues?
