T400 battery life: good as reviewed? (and compared to T61?)

[hydrostarr]

Have the T400 owners experienced battery life as good as what the following review claims?

(Also interested in comparison of battery life to T61; can anyone confirm the T400 is much better? Seems to be when comparing with notebookreview.com on T61.)

From notebookreview.com on T400:

Battery Life

I don't think I have ever used the word "insane" to describe battery life before and there is no doubt that the 14" T400 falls into that category. To get 10 hours of battery life from a notebook this size, most people think you would need a huge battery attached to the bottom of the case, another battery taking the place of the optical drive, and a big battery sticking out the back. With the T400 you can reach 9 hours and 41 minutes with the wireless enabled, screen backlight at 60%, and the laptop in integrated graphics mode using only the 84Wh 9-cell battery. In this situation the notebook is only consuming roughly 8.5 watts of power. In dedicated graphics mode under the same settings battery life falls by exactly 2 hours down to 7 hours and 41 minutes, and power draw increases to 10.5 watts. The 6-cell battery managed 6 hours and 4 hours and 28 minutes respectively.

I don't really know how long your average work or school day is, but 10 hours of juice is more than enough to get me through my day.

For those thinking about gaming with the T400 on battery power, you should have no problem with the 9-cell battery. Playing Portal with all GPU and CPU at peak performance levels the notebook estimate 3 hours of battery life remaining. While it is a big drop from nearly 10 hours under normal circumstances, you have more than enough time to play around through a few classes or meetings if needed.

Frequent travelers will enjoy the T400 as a movie playing notebook on flights or just trying to pass time wherever. When watching XVID encoded movies off the hard drive the 9-cell had an estimated 6 hours and 45 minutes of battery life, drawing 13 watts of power. Plenty of time to cover two full length movies. For those who must still use optical media for movies, you lose more than an hour of battery life with the optical drive needing to spin throughout the video.
