What should wear out first?
It’s really annoying when charging cables stop working, but it’s less annoying when you realize why: they’re designed to stop working.
It’s not that they’re supposed to be cheap and easy to break (though some clearly are), but that when you plug in your phone and there is a bit of friction between the cable and the USB-C port on your phone, it’s designed so that the cable takes the brunt of the wear so that your phone can keep working for years into the future.
It’s similar with many digital tablets, such as the reMarkable or Kindle Scribe. With those, the nub of the pen slowly wears out and needs to be replaced every few months, but it’s the same logic as your phone. Those devices have a satisfying bit of friction and sound to make it feel more like using a pencil, but that friction means that something needs to be wearing out. Should it be your tablet, or the little piece of plastic on the tip of the stylus?
If there is friction involved, something is slowly getting worn out. Thankfully, most of the time it’s the cheap thing being worn out so that the expensive thing can live on.
