I just want to know about the experience when using it, screen, performance, battery, ...
Screen: XS is more yellow, there is a lot of discussions about this in this forum, however it might be some variance in the displays. But my XS was noticeably warm. I had to turn off true tone while my ipad and my current XR have it on. On the XS, skin tone looked more reddish/peachy and therefore more natural while on the XR skintone is yellower. XS was also darker for the same brightness level. I guess bc of the darker black OLED has. The XS has a bigger ppi, but i didnt notice it even when i compared them together. Note though, its something i found out after returning the XS so i didnt actively look for screen sharpness, they looked the same to me. I hated XS screen at first but now I actually kinda missed the warmer display. The black was indeed darker and the XR is a little more washed out but XR looks better than my sister’s 6s.
Battery: i only had my XS for a day so i cant tell if XR is significantly better or just a lil bit better. My XR definitely the most apple has made in its history. I have had 5S and the battery was atrocious. But I was just not really impressed by the XR compared to people here bc my previous cheap android and iPad Pro have a long battery similar to XR so the XR doesnt really wow me tbh bc im used to it. But it lasts 12-18 hours not including sleeptime. 6 hours ago i charged it to 72% and right now it is in 38%.
Performance: honestly i didnt notice anything different. However I have visited apple authorized resellers to compare it side by side. Weirdly enough, XR was faster at launching apps. But i dont know which one is better at reloading safari. My XR reloads safari tabs especially after playing games/big apps.
Anything else: i didnt care about 3d touch. I think long touch is better. XS had quieter speakers but im not sure if mine was a defect but i thought it was quiet for $1000 devices i actually thought maybe it was supposed to sound natural lol. For size XS is definitely better. XR is heavy and my fingers are sore right now from typing these while lying on bed. Both of them are bad for single hand typing but im quite short and have tiny hands. Camera, XS was better looking but im not sure if its the camera or oled. Xr is grainier but photography is not my hobby.
In the end, XS is a better phone though for the screen, camera, and design (i like the black camera panel, match any case colors) but it just doesnt worth $250 for me... maybe $100-150? I returned the XS bc i regret spending that much $$$.... Besides the features are something youll forget after 2 weeks of use. Keep in mind i used a $250 android phone before this so clearly fancy specs and features arent my concern...
