Apple phone charger cords that regularly & randomly stop working. Also the plethora of different attachments for devices.
No idea about anything Apple (apart from a few Beatles records, oh, and Badfinger's first album), but I'm with you on attachments.
Just make everything USB-C, it plugs in whatever way you want and unlike mini-USB doesn't wear out after a couple of uses.
Bigwow, I agree. Never knew going through charging cables was an issue. Until recently I had a OnePlus, now I have a Samsung and it didn't come with a cord, so I just keep using the OnePlus cord which must be over 5 years old.
