Reset the iPhone
Generally, the iPhone is a very stable device and most people will not have any issues with it. However, if you never turn off your iPhone or you habitually download new apps to try, you may find yourself in a situation where your iPhone seems to be running slow. It may even lock up or freeze while you are using an app.
In many cases, simply restarting the iPhone by powering it off and on may clear things up. The iPhone is powered off by holding the Sleep/Wake button on the top right of the device for a few seconds until the red power off slider appears.
A more effective solution may be to reset the iPhone.
Resetting the iPhone can be accomplished by pressing and holding the Home button at the bottom center of the screen and the Sleep/Wake button on the top right of the device at the same time.
Hold both buttons for approximately ten seconds and you will see the screen go black. Continue holding until the white Apple logo appears. You can release both buttons once you see the Apple logo. The iPhone will restart and should function normally.
If you preform a reset when the iPhone is not locked up, the red power off slider may appear while you are holding the buttons. To reset the iPhone, continue holding the home button and sleep/wake button even after the red power off slider appears. The Apple logo will appear a few seconds after you see the red power off slider.
An iPhone reset will not normally remove or delete any apps,data, or settings.
Force Quit an App
Occasionally, you may just be having problems with one app. You could certainly reset the iPhone to clear the issue, but it might be quicker to force quit the app. To force quit an unresponsive app, simply press and hold the Sleep/Wake button until you see the red slider. When the slider appears, release the sleep/wake button and press and hold the Home button for several seconds. If it works correctly, your iPhone will close the unresponsive app and return you to the home screen.
Another method to force quit an app that may be sluggish or unresponsive is to use the multitasking menu. To access the multitasking menu, double click the Home button and a row of apps will appear below the dock. Scroll left or right until you find the app you want to quit. Tap and hold the app icon until a red badge with a minus sign appears and the apps begin to wiggle. Tap the red badge to force quit the app and any background processes it might be running. This does not delete the app from the iPhone, it just forces the app to completely quit so it will start fresh the next time you open it. When you finish force quitting the app, click the Home button to exit the force quit mode.
