Have you noticed your iPhone or iPad being a bit sluggish lately? You might be chewing up memory without even realizing it. You see, on iPhones and iPads, even when you "quit" an app, it continues to run in the background. This is wonderful for easy access, but if you have too many apps running at once it could slow down your device. And if you have never properly shut down an app, it's possibly every single app you have is still running and using memory. Luckily, closing your apps is a simple process.
1) Press your Home key twice quickly to bring up all your apps that are currently running. This feature puts your apps in order of most recently used, so you can jump between them quickly. It is also how you close apps that are running in the background.
2) Press and hold one of the app icons until they all start wiggling and red lines appear on each icon. It should only take a second or two.
3) Tap the red line on each icon until every icon disappears
