Battery charging issue in Samsung Galaxy S3 I have a Samsung Galaxy S3 and it is charging very very slowly when plugged into my PC. I deleted all my images and some videos and some other stuff and the charging seemed to speed up.

Is battery charging is related to available memory? I didn't think it was.
This is the due to the change in the supply current between the PC's USB port and the actual plugin charger you got with your device.

Current from USB port is less compared to that of the charger.

Hence time required to charge phone from PC usb port is more as that of charger
