Why do my phone chargers keep failing?

First off, what brand are you using? If they run hot, make sure they’re getting enough airflow around them because overheating can kill chargers fast. Also, check if the power rating is sufficient for your devices—if it's underpowered, it may cause issues.

If you’re using them in bed and yanking them around when you’re done, that could easily wear out the connectors in the charger or device. I've had chargers last for years because I'm careful with them!

It could be a mix of poor-quality chargers and maybe even some bad luck. Do you think you might be over-bending the cables or using them while they’re plugged in and tugging on them? That’s often a quick way to damage them.

I’ve heard that it’s best to use the official Nintendo charger for the Switch to avoid potential issues. All the cheap ones can sometimes cause problems or even damage your device.

Sounds like you're grabbing those budget chargers from Amazon or similar places. A lot of them just don’t hold up well over time.
