Terrible battery life [Original iPhone]

[simplegray]

My battery is so bad.

I got up today at 6:30am and by 4 this afternoon it was telling me "20% left, please charge"

I was on the phone for MAYBE 2 hours. WiFi off, lower on the brightness scale, email checks manually. I did a good amount of texting but that should NOT wear it down so quickly.

yesterday was worse. got up at 11am (i know that's late) and by 6 it was saying the same thing. and it takes a long time to charge.

any thoughts?

(other than that -- it's the best hardware device i own)

I work an 11 hour day, everyday.
I have the brightness set rather high.
I listen to the ipod while working to-from the parking lot for about 40 minutes.
I make numerous phone calls a day.
I check the mail at a 30 minute interval and use the wifi.. as well as the bluetooth function.
I'm searching the 'net
When I get home... battery is about 50%

I think that is pretty darn good.. but could be better.

yeah my phone is on all day from 10AM - 3AM with moderate usage of texting, phone, ipod, internet, wifi and i don't think ive ever seen it drop below 40%. i charge it every night to full and have never had it shut off because of low battery.
