Is it possible for 4gb of RAM to affect battery performance?

[Sdao]

Just wondering.

Yesterday I upgraded from 2gb to 4gb. I ran memtest on it and everything is great. The RAM checks out. Its working very well, no problems whatsoever.

I do notice that I'm not getting more than 3 hours of battery life on my MBP. My battery health is at 80% and I have 128 Cycles.

Is that normal?

Yeah I believe that is normal. Keep in mind the processes you are running and screen brightness are factors in battery life as well.

More RAM = less hard disk thrashing for virtual memory

Meaning you should get longer battery life if anything.

Meaning?

less power consumption? Think so. The hdd could probably take more power than the memory.
