If you want to become an iPhone power user, it's best to know about some of the hidden features Apple put in its operating system.
Here are a few of our favorites.
You can teach your iPhone to turn phrases or acronyms into anything you want. Go to Settings > General > Keyboard > Add New Shortcut to give it a try.
If you want to save an image from a website to your phone, tap and hold it until this menu pops up. Tap "Save Image" to store the photo on your phone. You can retrieve it later from your phone's Photos app.
Under Settings, you can switch on the iPhone's Do Not Disturb feature. That means you won't get notifications or calls while your phone is locked. It's best to switch this on while you're sleeping.
