I could be totally wrong about my understanding but I think phones and other devices “pull” the electricity needed to charge their batteries and if you plugged it into a wall plug that couldn’t supply enough juice it could damage the phone. I also hear people talk about some wall plugs charge their phone way faster so my question is can phones or other devices modulate how much they pull if they detect that a plug is capable of supplying more? Enlighten me people of the internet’s!

It’s more like the wall is pushing the electricity out, and your phone’s charger has circuitry that controls exactly how much electricity gets pushed into your phone. Simple chargers let electricity out at either 0.5 or 1 amps (an amp is a coulomb per second and a coulomb is just a number of electrons, so you can just think of it as some number of electrons per second) while some chargers have special circuitry that talks to the phone through the cable and decides how to maximize the amount of electricity it passes through the phone without damaging it.
