Battery Low [Q] Samsung Galaxy S4 GT-i9505 very slow charging

I have rooted my phone and flashed the latest 4.4.3 Pure Nexus GPE by Danvdh, Kryten2k35 and Ktoonsez. And it's been charging for so long, like 9 hours to fully charge from 14% battery. This has happened to my i9505 since I rooted it and installed custom ROMs, all GPE. What should I do? What is the problem? Please help
