I use Skype a lot to video chat. My Note 4 is either plugged into the original supplied Samsung Mains Power/Charger or my PC USB port. For maybe 1hr I will have the Skype App running; chatting with friend. The battery power level will be at 100% for most of the time. Am I damaging the battery keeping the phone plugged into a power source whilst running Skype. Also, what about if i was to leave the phone plugged in to the power charger for say 24hrs, does this damage the battery in any way?
