lower than expected phiX indicates that your quant was off. If you loaded your library to get 30% and only could align 15% phiX, that means that your 16S was approximately twice as concentrated as you thought so took up twice as many spots on the flowcell as you planned. Recovering roughly the amount of phiX as you put on is a decent indication that your library quant was correct
