Like everyone else, they last a month if you're lucky. I bought mine on July 13th. It is now August 16th. I threw one away last week and now I have to tape the 2nd of 3 to my phone because they are so cheaply built that when you plug them in they come loose after a few weeks. I just say the truth. I won't do it again. I still haven't found a charging cable that lasts 3-6 months :( I don't have kids running around plugging and unplugging them all the time so I think it's because they're so cheaply made they're 30 Years make days until they are given back and fail.
