1) Design. Initially, the reaction was "what kind of Chinese remnant did they do after 4k and 5k?" That's all until I saw it live.
2) Of course, it’s far from an ideal grip (it really needs a rubberized case), but it lies in the hand much more conveniently than 5k. Due to the straight forms, it was difficult to pick up the 5ku from the “lying on the table” position - the fingers simply slid along the edges. In 6ki, the round ends allow the fingers to run a little under the case, after which the phone is automatically in the palm of your hand.
3) The camera is really better than in 5k, the autofocus is just reactive. The fact that she sticks out does not interfere. Some people find this outwardly unpleasant, I don’t know, but for me, it’s done neatly and elegantly.
4) The screen is good, both in size and quality. Shifting the image down by double-tapping the home button is a great solution.
5) iOs, everything works smoothly, no lags.
6) The battery lasts longer than 5s (by the way, do not listen to those who say that the battery needs to be "rocked" by discharging it several times to 0 and then charging it to 100% - this is not necessary for lithium-ion batteries, which cost in the iPhone, as well as in all modern devices. The only thing that needs to be done immediately with such a battery is to charge it completely, but this is solely for the sake of calibration, and not increasing its capacity).
7) The build quality is excellent, nothing dangles, does not creak, is not pressed through, etc. I read a lot of complaints about poorly glued screens, but this problem, judging by the forums, arose among people who bought 6ku in the summer and autumn of 2022 in one chain of stores (they don’t miss the name here).
