Why did the technology companies' release (launch) prices of their latest products increase?

I compared the currencies of the developing countries against the US dollar and Euro. A significant percentage of the developing countries’ currencies lost value against euro (€) and the US dollar ($) in the last several years.

The gold price went down against euro € and US Dollar $ .

But almost all tech companies launch prices this year and the last year went up like from 15% to 30%. Please just look at the release prices of new smartphones and other electronics.

Why is it like this? I am really confused.
