Yes I barely used it that day. K-9 usually it not so high as it was that day because others were so low.
My phone is constantly trying to get a connection out. I don't turn it off because I need my calls. So I'm kinda screwed by Verizon.
The only thing that really matters is that it lasts long enough for me to use it and I work at home next to a docking station.
But for those having battery issues - the main issue may be your reception - other than the screen that's the second most juice drinker.
