It is now 2016 and the problem persists. My Acer tablet is now useless because it cannot be charged. That is a lot of work, finding software and storing personal data, to lose because of a cheap connector. I had a run of e-cigarettes fail within a few weeks because of the micro USB. I now buy only the ones with removable batteries. And good thing as the micro USB became loose in a day. Even my new Fire tablet connector because sloppy with only a few cycles.
It is the devices port that is going bad, though the cables aren't doing much better as the locking tabs don't spring back as they should. The metal is soft, not spring steel as it should be. I bought a half dozen of them and they all have the same problem.
I've gotta say that my Apple IPOD port has survived five year and gone through three cables. It is just a longer version of the micro USB. Same pin size, just more of them. Five years of use and it is tight as a ....... (You choose your analogy)
The charger for my cell phone, and the cell phone that came with it, have been through at least a year of use and are still going strong.
My best solution is to attach a short micro to standard USB cable permanently so I am only plugging and unplugging the robust standard USB connector. Even this hasn't been much help as the connectors (two so far) still get loose just having the cable attached.
No, replacing them is not "easy". Replacing AA batteries is easy. Having to purchase tools for soldering, learn how to do it properly, set up a work station, cracking open the case, managing to remove and replace the board mounted part without ripping up traces, is not "easy". If it were "easy", we wouldn't have a job called electronic tech.
This level of quality failure is simply unacceptable. That it has been a problem going back more than four years is unbelievable. This is a market failure.
My best solution is simply that I will never buy a device that is dependent solely on the micro USB for charging.
