How Long Does Your MacBook Unibody Battery Last?

MacBook Pro unibody battery comparisons…

Recently bought one of the 15" unibody Macbook Pros with the built in battery.

Fantastic machine. But, I'm slightly disappointed with the battery life.

I haven't done any structured testing of the battery life, but I seem to be getting between 3 and 4.5 hours out of it, depending on what I'm doing (although I haven't let it run completely flat apart from when I calibrated it). This is generally just word processing and web surfing/emails. When I'm on the road, I'm less likely to be using Photoshop or watching videos, so I hate to think what would happen if I really did some production work on it.

I never expected to get anywhere near the claimed maximum 7 hours, but I did expect something a bit better than this.

Is it just me, or is this similar to your real world experiences?

It can probably sit there on for 7 hours, maybe. If the temperature is right and the battery is new. Your experience is normal.

It's a powerful machine, which takes a lot of power. There are power paks available, I think.

4 hours is the most I have ever gotten out of my Macbook, and this is with turning the monitor brightness down to about 60% and turning off bluetooth.

Also, using anything that is processor intensive, such as Flash, or Photoshop will eat up battery life.

I've gotten about 3-4 of video on airplanes. Working without power supply on html, doc, xls, etc. I can sometimes get 5-6. Not the advertised 7, but still better than the sub 2 hrs I got on my vaio.
