> ... fleets of smartphones back in the windows mobile and blackberry days ...
In a completely unrelated world, where smartphones were not prohibitively expensive but still expensive enough to be a rare purchase, people in my country repaired old phones by buying new batteries. Those used to cost only a quarter to a half of the price of a new smartphone, and street-side cellphone accessories shops used to carry both original, branded batteries and cheap, knockoff batteries. The knockoffs were only about $10-$20 cheaper, and people were smart enough to know the difference it'd make.
