    Hello everyone, I was wondering if replacing ram for 8gb 1666mhz and the hd with an ssd would decrease battery life. Does it?

    A SSD consumes less power, and RAM is RAM, so in all likeliness, you'll probably gain 20-30 minutes of battery life.

    not true, the higher frequency ram will consume more power, an as he is upgrading the size as well there will be twice the amount of modules on the block, each consumes a set amount of power.

    The difference would still be quite minimal. In fact, I did not notice neither a drop or increase in battery life when I upgraded mine. RAM is pretty low-powered, DDR2 ram, for example consumes 400 mW or less. Since DDR3(what the OP has) is rated at 1.5V instead of 1.8V, it consumes even less power. My argument still stands, RAM will not be making a difference, in itself to the overall power draw.

    Now, if the OP uses his extra ram to open VM's, do RAM intensive work such as photoshop amongst other things, then YES, his battery life will decrease, but that'll be due to usage, not the RAM.
