Putting the phone on charge all night does not damage the battery.
Smartphones of today have lithium-ion batteries, and advanced technology that prevents overheating, overcharging and other issues that plagued earlier phones.
A full charge of the battery does not mean it does not have any more battery cells that can be charged.
The Lithium ions inside the lithium cobalt oxide layer are designed by manufacturers so that only half of it is used, to ensure repeat charging and discharging for maximum cycles
