It has been done more recently to, inclucing water resistance.
E.g. Samsung had their flagship Samsung Galaxy S5 series phone with removable battery in 2014.
I remember having an s5 “active” model that had even more water / dust / rugged protection. With the headphone port and removable back cover to change everything. Was a great phone at the time.
It also had an IR blaster you could use to control TV’s and other tech.
Headphone jack
Swappable battery
Expandable memory
IR blaster
It was basically the perfect phone
