How to get the most battery life for your iphone

I often see people with their iphones and they love it, but often complain of battery life issues.

Here are my top ten tips to help you maximize battery life on your iphone. This mainly applies to the Iphone First Gen phone, the iphone 3G, and the iphone 3GS. The iphone 4 has significantly better battery life than its predecessors, so some of the following are a non issue.

1. Adjust Screen 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.
Also, 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.

2. Turn off 3G if you don’t absolutely need it: Using 3G cellular networks loads data faster, but may also decrease battery life, especially in areas with limited 3G coverage or in large metal buildings where it constantly switches from EDGE to 3G. 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.

3. 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.
