I have disabled all my Widgets and have turned off all location and GPS settings and turned off Bluetooth and wifi as well as turned screen brightness too about 25% and backlight to 15 seconds. My battery is still going by way to fast. I am to 80% after about an hour of use. I take off charger at 530am and by 9 or ten im at 50% or less. .. I'm lost.
After a full charge, "spare parts" application shows that my battery has voltage 4158mV. A trained battery should have higher voltage. (Based on information from Motorola, the battery should be trained on page 8. http://www.motorola.com/staticfiles/...cks_EngVZW.pdf)
If you got a bad voltage number (< 4000mV), you may get a bad battery.
Here are some approximate battery usage we may get for DROID phone for a full charge of the battery. All are assumed to be continuous usage.
The battery should last about 9 hours when screen brightness turns to high in standby mode (Use screen only).
Battery may last 7 hours for phone call or internet data only (continue access without turning screen on).
Battery may last 3hours GPS navigation (Use Screen + GPS satellite + Data + CPU).
Battery may last 40+ hours for playing MP3 from SD card.
Battery may last 4 hours for playing Youtube movie (Use Screen + Data + CPU).
Battery may last 4 -7.5 hours for browsing Internet (Use Screen + Data + CPU).
The order of the amount of battery consumption is: GPS > DATA > Screen > WiFi > CPU.
The above is just my estimation without too much strictly test.
I doubt Weatherbug is the issue. It only updates infrequently. You can set it to update whenever you want.
I would say having too many widgets is a big drain.
I find that talking on the phone of course is a top drain. Following that is usage of the screen. You can't possibly get three days using the screen often.
I mean you can use GPS for continuous driving for 3 hours. If you just turn it on without continuous using it, it does not consume lots battery.
The screen used too much power because it is aways on and in use. Data and GPS is not always in use, though they consume more battery.
If you check this video, you can find GPS consume more battery power.

just put the phone on the cradle/charger after a near 14 hrs of use (no game play) and 50% left on the battery. at first it seemed like the update made the battery life worse, now i'm not so sure.
overall, i'm pleased.
