Is there any disadvantage of turning off the ADC clock between conversions (to save power)?

If I do this for example:

RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);
 
... Do one conversion...
 
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, DISABLE);

And does this even save any power?

If I already have enabled power down between conversions?

ADC_CR1.PDI = 1 ADC is powered down when waiting for a start event

ADC_CR1.PDD = 1 ADC is powered down during the delay

 Would the above save as much as using ADON?
