I've seen similar posts that complain of short lasting battery times but have not experienced it myself. I got the 3G when it was released, charge it every night before going to bed and unplug it every morning.

You can't overcharge the battery as there is built in circuitry that prevents that from happening. I leave bluetooth activated, location services have never been turned off, Wi-Fi is always on and still have over 50% remaining in the evening.

It's difficult to say whether you have a defective battery or just a new device that needs the battery to be conditioned. Give it some time and see if it improves. If not, return it for a replacement.

and wait so how do you know if the battery is fully charged? does the battery screen go away when its fully charged or it stays.. i don't know because when ever the battery got full i was scared to charge it for more thinking itd break my battery but i guess not

I've heard that push email and fetching email drains your battery pretty quick too. I have push and fetch on and mine is going down quicker then normal.

Wow, I can't get mine to die. I'm trying right now. Like others said, if it doesn't improve, return it for another.

Paying attention to just a few commonsense pointers will pay off with a longer battery lifespan and battery life for your iPhone. The most important thing is to keep your iPhone out of the sun or a hot car (including the glove box). Heat will degrade your battery’s performance the most.

Some Terms You Need to Understand
“Battery life” means the time your iPhone will run before it must be recharged. “Battery lifespan” means the total amount of time your battery will last before it must be replaced.


iPhone Temperate Zone. Your iPhone works best from 32° to 95° F. You should store it in environments of -4° to 113° F. That’s 0° to 35° C and -20° to 45° C for the metrically inclined. Keeping your iPhone as near room temperature as possible (72° F or 22° C) is ideal.
Viewing Usage Statistics
Awareness of how you use your iPhone and knowing how long your battery typically lasts can help you improve your its battery life. You can view your iPhone usage statistics by tapping the Settings icon on the Home screen and choosing Usage. Under the “Time since last full charge” heading you’ll see two items:
Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
Standby: Amount of time iPhone has been powered on since its last full charge, including the time the phone has been asleep.
Update to the Latest Software

Always make sure your iPhone has the latest software from Apple, as engineers may find new ways to optimize battery performance. Using iTunes 7.7 or later, you can update your iPhone with the latest software. Connect your iPhone to your computer, then select iPhone in the Source List. In the Summary panel, click “Check for Updates” to see if there’s a new version of the iPhone software available. Click Update to install the latest version.

Optimize Your Settings
Depending on how they are configured, a few features may decrease your iPhone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iPhone 2.0 or later software and may help extend your battery life.
Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
Turn off push mail: If you have a push mail account such as Yahoo!, MobileMe or Microsoft Exchange, turn off push mail when you don’t need it. Go to Settings > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
Minimize use of third-party applications: Excessive use of applications such as games that prevent the screen from dimming or shutting off or applications that use location services can reduce battery life.
Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.
Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.
Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ and tap Flat.
Turn off 3G: Using 3G cellular networks loads data faster, but may also decrease battery life, especially in areas with limited 3G coverage. To disable 3G, from the Home screen choose Settings > General > Network and set Enable 3G to Off. You will still be able to make and receive calls and access cellular data networks via EDGE or GPRS where available.
Lock Your iPhone
It may seem obvious, but you should lock your iPhone when you aren’t using it. You will be able to receive calls and text messages while it is locked, but nothing happens if you touch the screen. To lock iPhone, press the Sleep/Wake button. You can also set the Auto-Lock interval so your iPhone will turn off more quickly after a period of inactivity. To set Auto-Lock, go to Settings > General > Auto-Lock and set the interval to a short time, such as 1 minute.

Use iPhone Regularly
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

Question on this battery issue...Is it covered under the limited warranty to have the phone replaced? Mine just started draining quickly. I reset the usage info, and got a total of 10 hours standby and 5 hours use on a full charge, or is that normal? Seems like it should last longer. I have the brightness at minimum and nothing extra turned on...

Everything that you say turn off, I have most of it left on, with the exception of blue tooth. My battery can make it through the day quite easily with quite a bit left over. I think some people may be getting phones with bum batteries. I consider myself one of the lucky ones

make sure your brightness is turned down, also turn of the auto adjust option in the brightness settings, that alone drastically improved my battery life.

also i suggest letting the battery drain all the way out and then recharging it to full if you haven't done this already

Google it or check Apple.com

http://www.apple.com/batteries/maximizing-performance/

In the early years of the cell phone industry, the method you described was a correct one as all the batteries used at that time were nickel metal hydride.
You had to fully dicharge those bateries because if not, the battery built up a "memory". With the advent of better batteries, such as the lithiom ion.. this was no longer required. Even a few years later.. to present date, the battery used in the iPhone is a lithium polymr, which also does not require a full cycle drain.. it is actually harmful to do that a lot, although Apple suggests to to that once a month. There is a lot of good info for battery care on Apple.com. For the time being.. if you just put your phone on the charger every night, and moniter power consumption, you will be fine.
