After 16 months I too was having issues with the cable and purchased another and still had the same issue. The cable is a little loose in the connector when it is working and I discovered that moving it to the left or right will show charging or not. After reading this I cleaned out the port several times and discovered a pile of lint about the size of half a dime in there! All is well now and I have a spare cable to keep in the car.

I draped a thin dusting cloth (like that you get for cleaning glasses) over a bent paper clip and used that to clean out the inside of the port..
I was able to see an impressive amount of dust on the cloth after cleaning.
And now there seems to be no delay in charging.

GUM makes floss sticks for cleaning between your teeth. These work great in the lightning port for lint removal. The end is slightly flexible, and soft ridges on the side grab the lint. Solved my charging problem immediately.

NOT CHARGING (as soon as the battery icon goes over 98%) possibly caused by dust, lint, or corrosion?
The connector contacts are supposed to be gold plated, gold does not corrode.
Changing the Lightning cable (I have two Apple and three others) sometimes helps, maybe for a few minutes, then goes back to NOT CHARGING. This happens with different chargers, USB ports, or different cables, and is ALWAYS highly intermittent. One day it works, and then on another day it does not work. Apple charger or not, Apple cable or not. Next thing to try: cleaning the connector with contact cleaner?
Look at all the complaints, here and on many other websites. The old DOCK connector would sometimes fail, but the new LIGHTNING connector is even worse.
What is happening with iPhone, iPod, or iPad NOT charging with Lightning cables?

Try cleaning lightning connector on device side from dust and lint like described here: http://forums.macrumors.com/showpost.php?p=17023372&postcount=5. I just did it to mines - and now everything works like charm!

Another "me too" with compressed air. I was about to head to the Genius Bar when I found this post. Sprayed it out and voilá!, good connection.
