What happens when my device is fully charged? where does the charge send it’s power? Does the phone slowly let it go and charge back up? has plagued my mind forever!
In: Technology
The current that the phone draws from the wall/USB charger is reduced to only supply power that the device uses. The energy being taken from the source is reduced to whatever the phone needs in the moment, and nothing more. When you unplug the phone, it switches back to draining the battery.
