why iPhones are so expensive?

Here is The reason behind the question.

1. the first reason that iPhone are expensive is that they spend money on research and development. They also bring new technologies and their implementation.

you might have seen that there are so many new things(technology) that apple bring and after a few months or years later we see that android manufacturer copy them. so bringing something new is hard and costly too.

2. And the second reason is its brand value.

Apple's brand value is so big. people purchase their phone to show the status. apple makes only flagship phones, not midrange that's why their performance and built quality everything is so good as compared to Android. In Android, there are too many phones in the midrange and fewer flagship phones like pixel 2, Samsung Note series, S series, HTC and etc.

There are also expensive Android flagship phones like iPhones because they also invest their money in research and development and bring new technologies like Google's pixel phones Samsung's S series and note series, LG phones, Sony Xperia series etc.

There is a limitation in the iPhone because it's not an open source like Android. Android is an open source where everyone can develop and implement a program over here
