I purchased a USB cable from Walmart, thinking slove my charging issues however after about two weeks of using the charger I have to now keep the cable plugged in. I have to keep the charger from Walmart plugged, because it will go out although it says it's 99% charged. Should I purchase a USB cable from where I initially brought my phone from? Any suggestions as to my next step is and what type of USB cable? By the way, I wrote ZTE Community at the the year about my phone hanging up on calls drop my calls and I can only be on there for a second is from dropping my calls so I did everything that was suggested and it worked for about a week after that AT&t 6 not there so I'm thinking I need to get another type of phone or but I like the ZTE phones thank you please somebody help me.
