The iPhone has a lot of great features, but you can make it even more powerful by unlocking the iPhone hacks and tricks hidden within your smartphone. There are hundreds of these secret features, but here are our picks for the best iPhone hacks.

Want to charge your iPhone’s battery as quickly as possible? First, put it in Airplane Mode. Airplane Mode turns off many of your phone’s features, including cellular and Wi-Fi networking, so your battery has less work to do and charges faster. Remember to turn Airplane Mode off when you’re done charging.

To use Airplane Mode: Open the Control Center (swipe down from the top-right corner on iPhone X and up or up from the bottom on other models) and tap the airplane icon.

Want to receive notifications of new text messages, incoming calls or other useful information without looking at your iPhone screen or listening for sounds? With this hack you can make the camera flash on the back of your iPhone blink when you have a new notification.
