I think you might be unlucky or buying low-quality models. I have a 100W Minix NEO P2 that was one of the first GaN chargers available near me and it's still going strong 2 years later. I also have a 60W Satechi travel charger that's been powered-on 24/7 for 3 years now without the slightest hint of a problem. It's even been buried under cushions for hours at a time. The only charger I've had actually die was a Hama-branded device. Hama is the cheapest possible Chinese junk the brand can find.
