Not everybody is changing the phone or computers as often. Say if someone gifts me an old iPhone and the battery is getting old I do not have any Apple store around to replace it, I will be forced to trash a working phone because sending it to the country capital for an approved person to install an approved battery is probably more expensive then buying a new phone.
