Turn on Auto-Brightness
The iPhone has an ambient light sensor that adjusts the brightness of the screen based on the light around it (when there's more ambient light, the screen needs less power to be visible). Turn Auto-Brightness on and youll save battery because your screen will need to use less power in bright places.
Turn Data Push Off
The iPhone can be set to automatically suck email and other data down to it or, for some kinds of accounts, have data pushed out to it whenever new data becomes available. Youre probably realized by now that accessing wireless networks costs you battery life, so turning data push off, and thus reducing the number of times your phone connects to the network, will extend your batterys life. With push off, youll need to set your email to check periodically or do it manually.
Turn Off Location Services
One of the coolest features of the iPhone is its built-in GPS. This allows your phone to know where you are and give you exact driving directions, give that information to apps that help you find restaurants, and more. But, like any service that sends data over a network, it needs battery power to work. If youre not using Location Services, and dont plan to right away, turn them off and save some power.
Turn Off 3G
The iPhone 3G and later models can take advantage the speedy 3G cellular phone network. Not surprisingly, using 3G requires more battery life to get the quicker data speeds and higher-quality calls. Its tough to go slower, but if you need more battery, turn off 3G and just use the older, slower EDGE network. Your battery will last longer (though youll need it when youre downloading websites more slowly!).
Turn off Equalizer
The iPod app on the iPhone has an Equalizer feature that can adjust music to increase bass, decrease treble, etc. Because these adjustments are made on the fly, they require extra battery. Turn the equalizer off to conserve battery. This means you'll have a slightly modified listening experience - the battery savings might not be worht it to true audiophiles - but for those hoarding battery power, it's a good deal.
