why does fast charging in mobile phones charge the phone to a certain % very quickly and then significantly slows down?
In: Technology
* When you are charing a battery, you are basically moving electrons to one side and spots for electrons to go, on the other side.
* When the battery is almost dead, there is plenty of room for these electrons and so the flow easily which means they flow quickly.
* As the battery gets full, there is less and less room for new electrons so the process slows down.
