I have the exact same issue with my current laptop (2014 ASUS ZenBook) and I blame it on ASUS' poor design of the laptop-end plug. I have replaced the charger multiple times so far, about once a year I think. My SO has used a Lenovo for 4 years now and has never had this issue - however, their brick-to-wall cord broke recently, funnily enough.

I mostly like ZenBooks, but they really need to spend an extra $5-10 on more durable charging components. Mine had the charging receiver inside the laptop fail from wear, so I had to pop it open, remove the broken one, and solder in a new one I'd bought online (around $30, but it would have been a couple hundred bucks to send it off for repairs). Of course then the hinges failed a few months later... It's very frustrating for a "premium" laptop to cut corners on stuff like that.
