Re: why is my battery charging so slow..? draining fast too.!

I think you should be on at least android 4.3.x but are you using the factory charger and cable?

Have you tried a separate charger and usb cable?

When was the last time you checked for a software update?

I would at minimum wipe data cache via recovery mode. I would more so suggest a FDR if you feel up to it to boost the results the most.
