To maximize your Apple iPhone's battery you need to be proactive. A few tips to ensure the battery lasts as long as possible are to disable the wireless networks you do not need. For example bluetooth and WiFi are naturals to turn off at first.
The next step is to turn off the 3G network and revert to the much slower but less power-hungry Edge network. Personally, I have never done this and I understand if this is too drastic for you to undertake.
The next step is to reduce screen brightness. Turn off the Auto-Brightness setting and reduce the screen brightness to as low as you can stand to maximize battery.
You will need to also turn off the Fetch New Data settings in options and manually check for email. It is worth pointing out that the more often you check for email (15, 30 minutes, etc) the more you will use the battery. Turning on Push is a major battery drain so if you gets lots of email and want to maximize battery, be sure to check for email manually. Also keep in mind when you are in the e-mail application the system defaults to push automatically meaning new emails will be delivered as you are working.
In my testing, I have tried turning off the iPhone for periods when I will not be using it but I have found if I put the device in Airline Mode -- where all wireless networks are shut off, the phone uses negligible battery power for a period of hours. So, if you don't need the phone for many hours you can turn it off. A few hours -- put it in Airline Mode.
Obviously activities like email, web surfing and Google Maps do drain battery so just be aware of what you are doing if you need the iPhone to have enough battery left to guide you home after a wild night in a strange city.

Thanks for the great tips, cause iPhone's battery life has been a real disaster...However, what if i need my phone 24 hours a day? I mean everything's changing quickly in the business world and sometimes you need to be always reacheable otherwise you may loose something! And what if the activities like email and web surfing are essential for you? Something must be done on a deeper level, i mean by Apple.

That ia good area that peple would appreciate most. Cell phone batteries are expensive.
My Cell phone (Soney Erricson) still using the same original battery that it came with. I need to charge it once a day, but it does last me all day with 10 to 15 cell calls per day.
IPhone operates on Battery? Hmmmm.
Any time you transmit something, you use huge battery power. You don't need much for recieving signal. Think of it as a radio. The radio that you have and you tune it to listen many FM and AM stations, don't need much power. I remember back in 60s, I made a radio with no Battery at all and it was just a ear peace and a long wire.
But Radio stations that transmit signals do need lots and lots of power. Same goes for Cell phones but at much lower scale since thy are all digital these days, and also they only need to transmit to the nearest Cell site. So you still need lots of power to transmit, and that is why they ran out of power quicker than you think. Also any battery that gets charge over and over losses it's charging and retaining capability over a period of time (a few months and depends on # of recharges it receives).
One of the worst side effect of cell phone is, it's battery. It goes out quickly (even when it is brand new). They need to change it so it can use solar power and charge it's battery continously.
