Firstly Iphone 13 have some problems with camera, device make photoes with artifacts, with some black dots or black squares.They appear in random places and on radom devices. Mostly it is a software bag, but this bag is very strange for a mobile phone which cost more than 1000$
Secondly, IPhone 13 in some cases can not establish a connection with Apple Watch. Apple Support recommends to reset your network settings, but that doesn’t help.
Thirdly, Macro mode which appear on iphone 13 works very twitchy. Due to the fact that it turns on automatically, if you place the camera near the object, the process of switching from normal mode to macro looks very strange, and sometimes when you don’t need this mode, you can not turn it off, so it is unuseful in some situations.
Fourth problem, that new iphone have 120HZ screen, and it is only a market lifehack, because there are no apps in applestore, that can work with 120 hz, so you can not see the difference of high refresh rate modes and low refresh rate modes in apps. You can see the difference only in ordinary menu.
To summ up, Iphone 13 have a lot of minuses nowadays, that apple need to fix, and may be in future, after some weeks, I will recomend this iphone to buy.
