I had a similar problem with some Anker cables - they'd die with light use. I found at least one culprit in that my wife would rest her thumb on the cable connection while the phone charged. This bent something enough the cable would stop working. But some of them have simply stopped working after use on my desk or being carried around in my backpack for a while. I've switched to aukey for cables for that reason. Whether they're any more reliable is TBD.
