How is the battery life after adding 2GB more RAM on a MBP

[hajime]

Hello, I have a santa rosa MBP with 2GB RAM. I am considering to add 2GB more RAM to the machine. Could anybody please let me know the effect of having twice more RAM on battery life? Thanks.

I don't think RAM has any effect on battery life.

It might improve the battery life a tiny bit based on what you're doing. Basically, the more RAM you have, the less page outs you have and the less the hard drive is being used (which is a big power guzzler). Probably not very noticeable effect however (5 minutes, maybe?)

Haven't really noticed a huge difference. Still just a bit over 4 hours.
