I can vouch for this. I have an iPod Touch 5th generation. About two months ago I noticed that my device would not proper charge. First, noticed the message on screen displayed Battery Level 20%. Plugged in lightening adapter to charge, the charge level immediately went to 50% then no sooner 100%. Disconnected charging cable, used my Touch 5th generation & after a while Battery Level 20%. This continuously happened for a while before with the lightening adapter connected the iPod Touch would show Not Charging connected to the computer or AC adapter. Jiggle the cable, disconnected the cable, tried another cable with 30-pin to lightening adapter before seeing onscreen the red battery plus lightening bolt go on then to a black screen fluctuate between the two. Contacted Apple & Technical Support told me that it could be the charging port or battery that could be the issue. Long story short, a replacement is what Apple did for me. Now I am back in business. This was my situation.
