HTC One M8 Battery Issues?

[AC Question]

I've had my HTC One M8 (Harman/Kardon ed.) for a few months now. I used to charge it overnight and I'd wake up with it at 100%. It's always been a rapidly draining battery, but up until recently has it really deteriorated. When I'd plug it in, using the original HTC charger, it'd say something like "charger unable to charge phone" or "slow charge" and every day when I'd charge it overnight, the percentage would drop (i.e. i'd wake up and it'd be at 85%). Today, it had extreme difficulty charging at all, and now it's dead, stuck at 1%. I charged it for a few hours so it went to 5%, turned it on, but it only lasted a few seconds before shutting off again. I've tried practically everything from the re calibration method to switching out chargers. I seriously need help here, because I NEED my phone.

Have you tried a different cable and/or charging plug?
