I am on a 1750 Seidio slim extended battery and with normal to low use the battery life is HORRIBLE.
Tried the battery fix (Battery force FIX found!) and well it didn't work for me.
Charge,w/ device on till green.
Turn off device and replug the charger till it turns green again.
Unplug again and plug in again until it turns green.
I unplugged my device this morning and turned it on at 0600 by 0730 I was at 78%...
Checked mail, SMS's, market updates, twitters that I had received through the night.
WiFi off, email checking is at 30 min, sync is off, gps off, Enable always-on mobile device set to never...
This shouldn't be th is way not even with a software glitch.
The incredible makes my Droid look like a resourceful device in respect to battery life.
Something is draining your battery, you have to check your battery in phone setting/About phone/battery... and see what's using your power the most. I don't think its the battery but an App or something is running and draining the battery that much in that little time.
