Odds are you probably have a lot more than Safari and iTunes open. Is iTunes playing music? Are you watching YouTube videos or something? These can all contribute.

A big thing is screen brightness. The difference between having your laptop at full brightness and close to dark can make a huge difference. Try keeping the brightness as low as comfortably possible so you can maximize battery life.

Energy Saver settings, but, Coconut should tell a lot of information.

Try downloading Coconut battery or battery health monitor. This will provide info on your battery capacity and health

Something aint right.

Thankyou very much for your input:cool:

Open Activity Monitor, see if anything is using up a lot of CPU in the background.
Make sure you don't have any login items that are set to hide themselves.
Try recalibrating your battery.

Okay. For CPU:

Safari - No More than 50.0

Activity Monitor - No More Than 5.0

Everything else is usually less than 5.0

I've already re-calibrated my battery.

If Safari is running Flash apps/video, that's why.

50% CPU being used is fairly significant in terms of battery life/usage.

No, that's max. Most of the time it's around 15%.

Safari, FF, and iTunes are currently idling on my machine right now, taking up a combined 8% of the CPU. You must be doing something within those programs that is sucking battery life.
