Dealing with the same crap. I just recently made the developer functionality available by repeatedly hitting the build number section located in the "About the phone" heading in settings at the very bottom about 7-10 times but will have a notice of your progress and the amount needed. I selected " Keep the screen on when charging" the I downloaded the "Ampere" app at google play store, opened it up to run ( it shows wether the connection is good or if its n along with the mA amount but you can view its progress much easier and , ore confidently during the charging process. Ots been about 1½-2 hours now of non interrupted charging and went from 3% to 90%. So its not a complete solution or fix but accomplishes giving you peace pf mind and a charge phone. Almost forgot, after plugging in I rested the end of the connector (furthest end of connector plug piece from the end that goes into the phone)on top of something that about ⅜ high but on the same siface the phone is resting on to put a little added upwards pressure on the plug. Like the same direction if you where to lift the phone by grabbing the charging cord, that directional angle.
