The screen is most certainly not on most of the time. Also I didn't realize Dolphin uses that much power; from the stats you'd think I do nothing but surfing the web all the time, which is not true at all.
The phone is a Samsung Galaxy S (GT-I9000) running Cyanogenmod 7.1 (but I seem to remember that the start where more or less the same when the phone still had the stock software).
