Windows Phone Thoughts: RAM Upgrade Impact on Battery Life - Less Than You Think!

We've seen test results in iPAQ battery white papers where the more RAM an iPAQ has, the worse the battery life gets. I assumed that when I got my XDA back with 4x more RAM (from 32 MB to 128 MB) I'd see a significant drop in battery life. So much so that I ordered an XDA extended battery. Upon doing some tests, however, I was pleasently surprised that with the backlight and GPRS radio on, the battery life went from 8.2 hours down to 7.8 hours - a loss of only 5%. Not bad at all!
