Perhaps I need to clarify an earlier post of mine. I see that Stelv has his brightness set for 50%, and his auto sync turned off. I don't use compcache, so it doesn't factor in to my equation. I have my brightness *cranked*. Why? Because I like the way it looks. I have GPS and auto sync turned on all the time. Why? Because it makes my use of the phone easier, and increases my enjoyment of it.
Let's look at it this way: I bought the phone to enjoy it, and cutting back on this or that to extend battery life decreases my enjoyment. The Droid Incredible and the Droid X are set up similarly - the brightness is almost all the way up, the GPS and Sync are on, and I enjoy using them. The difference is that the Droid Incredible works fine with the extended battery, and allows me to boogie though the day, doing the various things I do with a phone, and at 8:00 at night, I've still got 85% to 90% battery charge left. No compromise on my part and no problem with the battery's part. The Dinc, by the way, is an early AMOLED model, with the beautiful, but battery draining screen.
Sadly, the two Motorola phones, run the same way by me, by 8:00 at night are puttering along at maybe 35-40% battery charge, and that makes me nervous. Yeah, I can plug any of the phones into the charger on my desk at work, and recharge them during the day, but the point is that the Incredible doesn't require it, while the other two do.
