ELI5: If electricity moves so fast, why does it take so long for phones to charge?

Because batteries do not store electricity.

They store chemicals. And when those chemicals react they MAKE electricity to power your phone.

Plugging your phone in doesnt fill your phone with electrity, its using the electricity to move the chemicals back to where they were.

And when that happens, the battery is able to make electricity again.
