Hey Feanixflame, Not sure I understand why it was not repaired, I'm guessing no problem was found. Anyway... Have you inspected the charging port for foreign debris? Packed lint in the bottom of the port can push the charging cable out preventing a solid electrical connection. With a strong light and a magnifying glass look in the port, your looking for signs of damage, cracks or missing pieces and debris. Attempt to blow out debris, but you may need to dig it out with a non-conductive probe, I find a round wooden toothpick works best. Be careful not to touch or bent the gold pins on the long side of the port. Also make sure the locking pins on the ends, the silver bumps on the ends, are free of debris and push back, they are a spring lock that holds the cable end in the port. If free of debris, try another cable and a different charging device if possible. (Trouble shooting 101.) It is possible your cable has developed a short. The lighting cables have a history of failure and Apple will replace the cable for free if found to be defective and you are within one year from date of purchase. The last thing to try would be to reset this iPod or last resort, after you make a full backup to your computer of all data / info on this iPod attempt a restore from backup or restore to new. If nothing works, contact your Apple store or the Apple Genius Bar, set up an appointment to have your iPod evaluated. Make sure your bring the iPod and charging cable. Good luck. Cheers.
