Long battery life is very important to an avid iPhone user. You can view your battery statistics in settings but here are a few tips to get the most out of your battery life: 1) Turn off push data: Applications such as mail can be set to fetch new data manually. The more frequently the application fetches new data, the faster the battery will drain. Also, you can reduce the amount of email accounts that are checked automatically. Settings -> Mail, Contacts, Calendars -> Fetch New Data 2) Lower brightness: Lowering the brightness is a great way to extend battery life. Alternatively, enable auto-brightness so the brightness will adjust depending on your current lighting conditions. Settings -> Brightness 3) Turn off bluetooth: Bluetooth should only be on if you are using it for things such as a hands free headset or a wireless keyboard. Settings -> General -> Bluetooth 4) Turn off location services: Applications that use GPS, such as camera and Twitter, will rapidly drain the battery. You can turn this off in settings. Settings -> General -> Location Services 5) Quit background apps: According to Apple, background apps are not actually running and don't use battery however, by quitting the 30 something apps you may not even know are running, you can extend the battery life slightly. This only affects iPhones with multi-tasking. Double Tap Home Button -> Hold on an app logo until they start to shake -> Tap the red circle in the top left 6) Turn off notifications for apps: This reduces the amount of apps needing to constantly monitor your iPhones status. Unless you like receiving Facebook notifications at 3am, this should be off anyway. Settings -> Notifications 7) Update with the latest iOS: Those Apple guys don't release updates for their own benefit. Apple engineers may find new ways of optimising battery performance so it is important to keep up to date with new iOS updates. Check for updates on iTunes 8) Store as close to room temperature as possible: Heat rapidly degrades the iPhones battery lifespan and can damage the internal components themselves. Don't store the phone in direct sunlight or even the glove compartment of a car. Heat will degrade the battery the most. 9) Use the iPhone regularly: It may seem stupid but to make full use of the lithium polymer batteries, it is important to keep the electrons moving frequently. Make sure to fully charge the phone at least once a month. 10) Use airplane mode in low or no-coverage areas: Airplane mode automatically turns off wi-fi and 3G and so extends battery life. Settings -> Airplane Mode And there you go. Ten tips for improving battery performance. Optimising your setting is very important and can help you get the most out of your iPhone.
