Strange charging issue with HTC Amaze - Red LED on but won't charge

view story

http://forum.xda-developers.com – Hi, I'm bad at explaining things but will do my best. so here it goes: When connected to a charger, my htc ruby that shows the battery charging icon and the red led light but the battery doesn't actually charge. I then purchased an anker battery+charger combo and it charged the oem battery to its fullest and it lasted all day as usual. Has anyone encountered this wierd issue before? I also went ahead and reset the phone using twrp but that didn't fix the issue. Also, the phone is running CM10.1 nightly 0415 I think. thanks (HowTos)
