Contrary to what you have read about using the phone while it is charging, that will NOT cause damage to the battery.
And, the battery will NOT overcharge either...... the internet hangs onto "bad info" forever because the internet does not expire........ what you read is only applicable to ancient battery technology and chargers.
Samsung built in a smart charger chip to prevent that from happening and the new battery technologies are far better than what we had many years ago. NiCad batteries were horrible about being mistreated.
the technical explanation is very long, but suffice it to say, your S5's battery did not expire prematurely from overcharging or using it while being charged.
