How to Increase iPhone 3G's Battery Life Tips

Is the battery in your new iphone does not take much load? You're not alone. Check out these tips to live with the iPhone 3G's battery life while using it a whole lot.

. Dimming the screen:
the screen brightens uses more battery power. Change this under Settings -> Brightness

. Turning off 3G :
If you are in a location where 3G does not work, then you will not need to activate this service on your iphone and you do not get any benefit from the phone battery-hungry 3G radio. By turning it off, you double the length of your iPhone 3G battery, 5 hours of talk time to 10.
For turning off 3G : In home screen, tap Settings / General / Network /
Enable 3G Off

. Turning off Wi-Fi :
As with 3G , If you are in a location where Wi-Fi does not work, then you will not need to activate this service on your iphone and you do not get any benefit from the phone battery.
to do that : In home screen, tap Settings/Wi-Fi/On/Off.

. Turning off Bluetooth:

If you’re not using a Bluetooth headset, then for heaven’s sake shut down that Bluetooth radio. In Settings, tap General, and turn off Bluetooth.

. Turning off push e-mail:

If your email, calendar, and address book are kept constantly synced with your Macs or PCs, then you’ve probably gotten yourself involved with Yahoo Mail, Microsoft Exchange , or MobileMe . It’s pretty amazing to know that your iPhone is constantly kept current with the mothership—but all that continual sniffing of the airwaves, looking for updates, costs you battery power. If you can do without the immediacy, visit Settings / Fetch New Data ; consider turning off Push and letting your iPhone check for new information, say, every 15, 30, or 60 minutes.

. Turning off GPS:

If you are not be needing the iPhone to track your location, save it the power required to operate the GPS chip and the other location circuits.
In Settings, tap General, and turn off Location Services.
