I travel for a living and I have several chargers that I use. The charger has to be moved around within the phone in order for it to charge the phone and even then it is not a guarantee. This is the second phone that I have had in less than two years that keeps doing this. Even the charger that came in the box will not work very well. I depend on my phone to be able to communicate with my family as I am gone months at a time. This is ridiculous. I think that I am about ready to go with a different brand of phone. I have changed USB cables, car adapters, wall adapters. The only thing that I have not changed is the phone. These other cables will charge other devices with no issue.
