[Eeglablist] Power reduction issue after rejecting ICs

I use ICA to reject eye blink, muscle artifact,etc...
I calculated the power reduction changes(after rejection vs.before ), and
it's around 46%!
after preprocessing I'll be doing fft and subsequent power analysis. Is it
OK to proceed since power reduction is around 50%?
Is there any alternative way of rejecting artifacts,... so I don't have
that much of power reduction?
Thanks in advance for any advice
