The first day I got it, it came out of the box at 75% battery. I didn't charge it until it got down to 5%. Then I fully charged it and used it to 18% today. If I run the battery down and up for a few days will that help me to get a good battery life?
Got a tip for us?

Maybe once, but not more. The laptops will calibrate the battery by running it to zero. Not sure if the iPhone has the same feature.
If you don't use Bluetooth then go to the settings and turn it off.
If you are browsing the web and have access to WiFi then use that in preference to 3G.
Set the screen brightness at a comfortable level but not as bright as possible.

Its simple, turn off 3g, bluetooth, and turn down screen brightness and you'll get good battery life, but don't sweat it, the new battery is easily capable of a full days use almost no matter what you throw at it*

You never get the best battery life straight out of the box. Calibrate it first and things will improve after the first few days.
If you read the instruction manual you will not find any reference to "calibrating" the battery. It is a urban myth. Just use it and enjoy it and you'll have a great experience.
The owners manual does say that about once a month you want to 'exercise' the battery by running it down to maybe 10% then recharging it, but that is all the maintence needed.

Apple said:
That is what I class as calibration, doing this does improve battery life.
So if, as you claim, you'll likely get a full day out of it anyway, why are you suggesting that he turn off 3G and cripple the phone?
What's the point in having a phone that lasts an hour longer if you hate it while you're using it?
I also believe that calibrating an iPhone is something of a myth.
However, I found that my 3gs really benefitted from frequent charging. I could tell this by comparing it to my wifes. She has a more carefree attitude towards tec stuff. After a few months, mine had the best battery by far. And I charged it almost every night - as I will do my iPhone 4.

Huh?
"... but don't sweat it, the new battery is easily capable of a full days use almost no matter what you throw at it".
I read that as saying that you could do all the stuff he suggests to squeeze every last minute out of the battery but "don't sweat it" (translation - don't bother to do it?) ... "full days use" ... "no matter what you throw at it" (translation - it'll last you a full day without needing to do all the stuff he suggested and just leave everything on).
I don't understand why you're having a go at him. The way I read what he wrote, he was saying exactly what you just said.
