1. Nice design (subjective, of course, but nonetheless), monolithic case with excellent assembly, expensive materials (glass, metal chassis).
2. An excellent screen with pleasant color reproduction, looks better than many amoled matrices on Android smartphones in the middle segment (no kidding). I was pleased that even in the sun everything more or less remains readable (that is, the brightness margin is not bad, but, of course, not a reference by today's standards, especially when compared with amoled matrices on the latest iPhone models). The standard 60 hertz of the screen is felt in terms of smoothness like some 90 hertz on the middle peasants on android.
3. Touch ID recognizes fingerprints instantly (if the fingers, of course, are dry, but sometimes they manage to recognize wet ones). I’ll also add here that when you save a login and password for any application, email client or site, you do not need to remember all this data, later when you enter a site or account in an application, you can simply put your finger on the scanner and data automatically filled, insanely convenient.
4. Excellent vibration (powerful, feels great in your pocket, tactilely very pleasant, and also coolly integrated into the system and various applications, both pre-installed and third-party ones, for example, the same Telegram).
5. Almost reference work of the light sensor.
6. Works almost perfectly on the latest version of iOS 14, excellent smoothness, it is clear that there is still a reserve of power for the future. Great for keeping apps in the background and not unloading them.
7. Decent main camera (in conditions of sufficient illumination), there is a 2x optical zoom without loss of quality. Excellent video quality (well, it's an iPhone, you know). Portrait mode, if you try, produces very decent results. I am glad that the blur when the portrait mode is activated works not only when photographing people, but also when capturing other objects.
All other pluses will rather be applicable to any current iPhone model, including iOS.
