Like I said before, I used custom power saver settings and I provided the parameters above.
I also have shut off WiFi and Bluetooth, but I keep GPS on (it only turns on when the app needs it) along with data. The key to getting up to 7 days standby is to shut off the 3G/data when it is not being used. That uses up quite a bit of juice, but the display brightness should also be set on the lowest setting possible. I use AUTO only when I am outdoors or need to use the Droid2 as a GPS in the car.
The Motorola site says the Droid2 is capable of something like 400 hours standby, which I am not sure how to get this unless everything is shut off (airplane mode, no incoming data/text/calls).
But if I use the Night time power saver mode, I can get up to 3-4 days standby time with minimal usage of the phone. If I make a lot of calls, listen to music, surf the web, and use Pandora, I get about 1-2 days max. I felt this was pretty bad considering my company issued BlackBerry will easily get 7 days of standby time with light to medium usage.
