Why don’t phone batteries limit charging after reaching some threshold charge percent?
They do. Any device powered by a rechargeable lithium ion battery has a charge controller. Batteries are charged by applying a voltage greater than the cell voltage of the battery.
The Short Answer
They do. Any device powered by a rechargeable lithium ion battery has a charge controller. Batteries are charged by applying a voltage greater than the cell voltage of the battery. If lithium ion batteries are left with a higher voltage applied after they are finished, they could catch fire.
