Below are some tips and tricks that you may want to try if you’d like to extend your iPhone’s battery life.

Disable Wi-Fi

If you’re not going to be using a Wi-Fi connection, you should disable it on your iPhone so that your iPhone’s battery doesn’t drain when you’re either connected to a wireless access point or when your iPhone’s searching for new wireless access points.

If you’d like to disable your iPhone’s Wi-Fi connection, you can do so by going to the Settings menu and then to the “Wi-Fi” section, where you should be able to disable your Wi-Fi connection.

Lower the Brightness of the Screen

The brighter your iPhone’s screen is, the more your battery will be drained. If you would like to prolong your battery life by turning down the brightness of your iPhone’s screen, you can do so by going to the Settings menu and then to the “Brightness” section, where you should be able to select a brightness that you like.

Disable your iPhone’s 3G Connection

If you’re using your iPhone’s 3G connection, it will drain your battery faster than if you disabled it. Even if you disable your iPhone’s 3G connection, you will still be able to access the Internet, as well as fetch new data, but you will be using EVDO, rather than 3G, which may be slower, but you will still end up saving battery life.

If you would like to disable your iPhone’s 3G connection, you can do so by going to the Settings menu and then to the “General” section. From there, you should then go to the “Network” section, where you should be able to enable or disable your iPhone’s 3G connection.

Disable Bluetooth

Using Bluetooth will also drain your iPhone’s battery faster than if you weren’t using it. If you would like to disable Bluetooh, you can do so by going to the Settings menu and then to the “General” section. From there, you should go to the “Bluetooth” section, where you should be able to either enable or disable Bluetooth.

Disable Push Notifications

Even though Push notifications can be useful for knowing that you’ve received a new e-mail or tweet, they can also hinder your iPhone’s battery life.

If you would like to disable Push Notifications, you can do so by going to the Settings menu and then to the “Notifications” section, where you should be able to choose which applications are able to send you Push Notifications, as well as if you’d like to enable or disable Push Notifications all together.

If you are someone who would rather still use all of the above features on your iPhone, perhaps you should consider purchasing a portable charger, such as the Kensington Battery Pack and Charger, which is available from the Apple Online Store or the Monster Charging Case for iPhone, which is available from the Monster Cable website.
