Here is something I did. I just turned the phone off and let it charge to 100%. Then I unplugged it counted to 10 and plugged it back in. To my surprise it started charging again. Then I just kept doing that until the light was green when I plugged it in. Turned on the phone let it charge all the way up to 100% used a battery cal app and BAM! Great battery life... Hope this works for you.
