Samsung used to include wired earphones, a USB cable and charger in the Galaxy S Series phones boxes, right up to the Galaxy S20 Series lineup.
Ditching in-box accessories and using smaller boxes can benefit the environment. However, it may also be said that this decision will benefit Samsung’s profits more than anything else because of saving costs for manufacturing and importing those accessories, as well as attracting additional revenue by selling those accessories separately.
It remains to be seen whether rumors of removing the charger and headphones from the Galaxy S21 Series phones will also affect non-flagship Samsung phones. In general, we will undoubtedly hear more about the Galaxy S21 Series lineup in the coming days and weeks given that it is expected to be announced sooner than usual, and most likely next January.
