You’re not alone OP. I gave up the plus size with the 7 and haven’t missed it. Had an 8 and wasn’t even planning to buy the X until I got a surprise promotion at work last week. Decided to treat myself when I found stock in store last Saturday.
Love the big screen and the gestures more than I thought I would. But my screen is very yellow and it’s kind of driving me crazy. Also, the way Apple has calibrated its OLED panels leaves not a ton of difference between them and their LCD phones. Yes blacks are nice in a dark room, but I wasn’t nearly as blown away as I expected to be. Same goes for the cameras. Portrait mode is cool. But overall I’m seeing a lot of photos with the watercolor smudge thing going on. The camera seems to especially struggle in low light and I’m not seeing a ton of benefit from OIS on the telephoto lens (seems to still switch back to the wide angle in low light). Battery life is also not great. It’s maaaaybe the same as I was getting on my 8 or maybe an hour or so worse. No way is it 2 hours better like Apple is claiming.
I’m planning to give it a bit more time, but I’m finding myself having a hard time justifying the price of this phone. I can afford it, but I’m not sure it’s worth it. I may try to switch it out as it kind of sounds like I have a bad unit after I wrote all this out haha! But I might also just wait until next year and stick with the 8. I will say I like the direction Apple is heading with the X. Makes me excited for the future of the iPhone!
