oh heck naw, my battery sucks butte also. i am on my second battery replacement from tmobile. all with the same results.
but with a few easy tweeks you can get 2 days with the Behold.
1. i turn off 3G when i sleep
2. i found that app/taskillers do nothing but take up memeory and battery life. i dont use them
3. anything with "follow me" location stuff. i turned my weather bug off and set locations for it and to update every 30 min
4. besides email and sports tap i set things to update every 30min or only refresh when i start the app
5. calibrate/condition the battery once a month
6. VIBRATION FEEDBACK will drain the battery fast, turn it way down if you really need it or turn it off
7. Using the phone for talking
with a smart phone i make less calls cause of email, text, twitter and facebook.
I get two days and have GPS on and brightness either at the middle, 3, or the brightest, 5, and many apps and widgets going.
but heavy youtube and web days or family yapping days i will only get 16 hours.
