Apple's iPhone 4G can take a little while to get used to.
The 4th-generation iPhone is a technological jump from previous generations. Introduced in 2010, the iPhone 4 had an improved camera, screen, battery and motion sensors. With the iPhone's large number of features and downloadable apps, becoming accustomed to using it can take a little while to learn.
Longer Battery Life
To make your battery charge last the longest, turn off the features you don't need. For example, turn off location services, push notifications and Bluetooth when you don't need them. Also, change your settings so that it checks your mail automatically less often, and reduce the brightness as much as you can. Lock your iPhone when you aren't using it. To optimize the battery life, use your iPhone regularly. Also, it's good to give your iPhone a full charge cycle once a month by charging the battery up to 100 percent and then letting it run down all the way.
Photos
The 4th-generation iPhone comes with a front-facing and rear-facing camera. The rear-facing camera is 5 megapixels. You can zoom in on an object by tapping anywhere on the screen and then adjusting the zoom bar that appears. The front-facing camera can be used to take a self-portrait, or to make video calls (called FaceTime). Switch between the front and rear camera by pressing the button in the top right corner of the screen in the camera app.
Punctuation/Numbers
Pressing the space bar twice will quickly add a period at the end of a sentence. If you want to insert another punctuation mark or number quickly, press and hold the "123" that changes the menu. Select your punctuation mark or number and then release the "123" button to insert.
Apps
Every once in a while, check your App Store to see if you need to update any applications. These will also show your home screen on top of the App Store icon. Try to do this when you're connected to a Wi-Fi network, so you're not eating up your allotted 3G download amount. From time to time, you may want to check which apps are open in the background. If you have lots of apps open, it may slow down your phone. Double-tap the home button to see which apps are currently running, and then tap and hold one of the icons. When the red "-" button appears, select the ones that you want to close. (Turning off your iPhone occasionally will also solve this problem.)
Text Messages
Most new users find it easier to turn the iPhone on its side for a longer touch-screen keyboard. If you're bilingual, you can add an international keyboard in the settings menu under "General" and then "Keyboard." You can add or change specific dictionary entries in the same section by selecting "Edit User Dictionary." The iPhone keeps records of all exchanged text messages, but if you want to delete a particular one, press "Edit," then tap a text message and then "Delete." If you're worried about overloading someone's phone with a lengthy text message, turn on SMS character count. Go to "Settings," then "Messages" and turn on Character Count.
