Up til this week, my phone has always charged fine at my bedside plug, my computer, and the plug in my craft room. Suddenly, it will only charge at my computer. Went out and bought two identical cables for my bedroom and the computer and plugged both in. Still, computer is the only place the the phone charges. My tablet (Kindle) recharges fine at all ports. Nothing in the phone system has changed in any way as far as I know, no new programs, the phone is not rooted.
