Is my iPhone 3GS Battery Normal?

[JS82712]

3G OFF
Location Service OFF
Push OFF
Fetch OFF
Brightness 40%

I usually do some light web browsing for about 10 minutes in the morning, check facebook, check e-mail....etc and about 15 minutes of games. Other times just listening to music on the car. Even when my 3GS is on standby, the battery drains at about 1% every 30 minutes. Is my battery normal?

1% every 30 minutes? Haha, mine does about 1% every 5-10 minutes with location services on and 3G/push/fetch off, not using any apps.

I've let my run down to 2% (auto shutoff) in a vain attempt to calibrate it. Re-charging to full now, and hopefully the next few days will show improvement.

Keep in mind batteries are not mechanical components, they are chemicals, and therefore there may be a "break in"/"warm up" period. Its not all black and white with these things.
