Help! Chipgate or what?

I have a brand new 64g iPhone 6plus
Now I'm confused about one thing especially...
I know there's a sensor thing for force touch.
When my phone rings (I need vibration cause I'm hearing impaired) I feel like a drum hitting my phone.
I have this phone 3 days I'm still in window to exchange it.
Now is that Normal?
Second question and it may be nothing or it may be valid.
I checked and I have the what's called the ""crappy Samsung chip "
Battery life is ok
Phone isn't much faster or diff than my 6plus
I'm bummed I sold it because I don't see much difference other than photos...BUT love the pics and rose gold so $$ isn't a big issue BUT I want what I paid for and am supposed to have.
Is this normal?
