Under-clock And Now My Phone Takes 3 Hours To Charge ?? topic

from stweaks i put the lowest voltage to 100mhz and 900mv
everything works perfectly but it takes three hours to charge ( 20% to 95% )
when i was on stock it would take 1hr 45min

i have resurection remix rom 4.4.2
dorimanx kernel 10

is it the undervolt / underclock thats causing the problem? :confused:
