+Smartphones aren't noted for their incredible battery life -- with great power comes the need for great batteries. While batteries are improving, mobile devices still don't last long enough for most of our tastes.
+
+Apple's iPhone is one of the better candidate when it comes to battery life, but despite Apple's claims of up to 7 hours of talk time on 3G, in our experience the battery begins to fade away much sooner.
+
+Still, if you tweak a few settings, turn off some features when you don't need them and dim your screen a bit it'll go a long way toward getting you 7 hours of 3G use.
+
+Here's our guide to making your iPhone battery last a bit longer
+
+== The obvious ==
+
+# Dim the screen -- This is probably the biggest single thing you can do to save battery life. Head to Settings, select Brightness and dim down the screen.
+
+# Lock your iPhone when you aren't using it -- Sure it will auto-lock after a set period of time, but why leave it sitting there wasting battery when it's so simple to lock? Just make it a habit of pressing the lock button every time you put it down. While you're at it, shorten the auto-lock settings; head to Settings > General > Auto-Lock and set the interval to a shorter time.
+
+== Features worth disabling ==
+
+# Turn off 3G -- You're on the AT&T network, there's no 3G coverage anyway. Just kidding. But if you're on wifi, turn off the 3G network. Also, if you in a place you know there's no 3G coverage, don't waste battery searching for it.
+
+# Learn to Love Airplane Mode -- The easiest way to temporarily disable all forms of battery draining networking is to switch into Airplane Mode when you don't need to connect, say when you're just listening to music on the bus.
+
+# Watch your apps -- There are two types of apps that are particularly hard on your iPhone's batteries -- games that never let the screen dim and location based services that constantly check your geo whereabouts. Make sure to shutdown such apps when you're not using them.
+
+# Disable Push notification -- The built-in Mail app as well as dozens of other apps poll servers in the background look for new tweets, mail and messages, all of which costs your precious battery life. Open Settings and select Mail, Contacts, Calendars. Then select Fetch New Data and turn off Push.
+
+# Delay data fetching -- So you've turned off push notifications, go a step further and make Mail and other apps check-in with the server less frequently. To increase the fetch interval, go to Settings and select Mail, Contacts, Calendars. Then select Fetch New Data and tap Hourly. Note that this is a global setting add applies to all apps. It's also worth noting that setting Fetch New Data to hourly means you can't find your iPhone using the MobileMe Find My iPhone tools.
+
+== Extending the life of the battery ==
+
+While all of the above will help your battery last a bit longer, none of it extends the life of the battery. For that Apple [http://www.apple.com/batteries/iphone.html recommends "cycling" your iPhone battery once a month], which means charging it all the way up and then running it all the way down. \ No newline at end of file
