Perhaps because multiple high profile third party tests have shown the 8 Plus lasting longer than the X in when tested.

I've been using the X for a week and I'm definitely returning it for an 8 plus.
While I absolutely love the display color and edge to edge it's still not enough to make up for these two things that are absolute deal breakers for me in practice:
- The screen is absolutely smaller in practical every day use due to being more narrow. I couldn't care less about extra room at the top. I'm always scrolling to keep whatever I'm looking at in the middle of the screen anyway. When I'm texting I don't give a crap about messages that are farther up the page, I care about the keyboard size.
When using it in profile mode which is 100% of the time other than landscape video for me, it is noticeably smaller than the Plus. In actual fact it is the same display width as the regular 8 NOT the 8 plus. (well covered by tech reviewers now) This also means a narrower keyboard in addition to having to zoom a bit more just to achieve the same side by side scaling.
- Facial recognition is notably slower than the fingerprint unlock even when it gets it right the first time. On occasions when the angle, light, or anything else is off it is dramatically slower. With my 7 Plus I could unlock my phone while it's still laying on my desk with a touch. Now I MUST pick up my phone or friggin lean over it EVERY DAMN TIME. Considering I pick up my phone literally hundreds of times a day that annoyance adds up.
Paying $200 more for even a few minutes of added irritation every single damn day is just adding insult to injury and I'll gladly sacrifice the gorgeous screen and sexier design for a phone with a wider display and bigger keyboard that unlocks faster.
I am not exaggerating when I say that at this point I'd gladly pay $100 more for the 8 plus. That I'm actually going to be saving money instead is just a nice added bonus.
