subject: How To Improve Your Iphone's Battery Life [print this page] The iPhone is quickly becoming the most popular smartphone. The biggest issue users have been complaining about is the battery life of this and several other smartphones. Little do they know that their settings and behavior can make all the difference. Here are a few things you can do to increase the juice per charge on your iPhone 3G(s).
Put the device on sleep mode after use
This is one of the biggest saves you can make that don't impact your experience in any way. We all know the situation. Your watching a movie at your friends house; and you hear two beeps indicating that you just received a message on your iphone. You take it out of your pocket and answer the message. Now here is the important part. Most people just put it back in their pocket after they're done. This is wrong! By default the screen won't turn off until a minute after your last contact. What you should do is always hit the button on top of the iPhone when you're done. This way the screen wont be active when it's not necessary. Mind you the screen is the biggest energy sucker!
Turn off GPS
Apple advises this heavily in their battery optimizing articles with reason. The GPS is great but you won't need it every time. In fact the only time you use it is when you're navigating, using curtain 3rd party apps (very few use it) and when taking photos. The latter one few people know but the iPhone 3G(s) actually geo-tags your photos so you can see where you took them in iPhoto on the mac. When you're not using these features please turn GPS off in the settings of your device. It takes just a handful of seconds to turn it on/off so don't be sloppy.
Screen brightness
Lower is better for battery life. I advise to use the 'auto' setting. The sensor on top of your screen will determine what the best brightness is in every situation. Putting the brightness on full strength for a longer period of time will suck your battery dry before night falls!
Turn off 3G
3G is the internet connection your iPhone has (in curtain areas) outside your house. Turn it off if you don't plan to use the internet actively on your trip. The switch will tell your iPhone to only use Edge or Wi-Fi internet, both are more energy efficient.
Turn off push and fetch email
By default your iPhone will only check your e-mails when you hit the mail app. This is best for your battery life. If you prefer the better battery life above the comfort of being notified of new e-mails than make sure fetch and push email are turned off.
Update to the latest firmware and 3rd party apps
Make sure your iPhone is running the latest firmware update. As of writing that's 3.1.2. And delete all apps you aren't using. That will make a (minimal) impact on your battery life as well. And there you have it. A few things you can do to improve the battery life of your iPhone, iPhone 3G, iPhone 3GS and even your iPod Touch. I hope
