They're wrong here.

The charging logic is inside the phone. The power brick you plug into the wall is just a power supply and isn't responsible for stopping charging when full.

The brick also only limits maximum current for its own safety, the phone decides how much to draw and will not draw more than it is designed for.

A charger will only damage your phone if it provides out of spec voltage that's too high.

That statement is actually so wrong and shows so little understanding of the topic that I dismissed the entire article. Even a cheap garbage-grade 5V 1A charger from AliExpress won't damage your phone, it just won't charge it well.

Yeah for some reason these types of articles almost always get something wrong and just make things more confusing for people that come across them.

How did they manage to get so many basic facts wrong in one article? Anyone whose used a lithium ion battery in bellow freezing temperatures knows that it has a huge impact on the battery capacity.
