1. Lock your camera's focal point.
Isn't it so annoying how you have to keep tapping the screen to make your camera focus? Well by pressing and holding down your screen for 3-4 seconds you can place an "AF Lock" on your focal point. Then your camera will not lose focus while taking your next picture.
2. Gently shake your phone to delete an entire message.
Don't want to hit the back button to have to delete your entire text message that you know you'll regret sending? Just shake your phone and then hit "Undo." Simple as that.
3. Charge your battery faster by turning on Airplane Mode.
It normally takes an hour or two to fully charge an iPhone to 100%. But by simply putting it on airplane, it'll charge in half the time
4. There is no need to finish the rest of your URL.
While on any screen with the keyboard open, simply push and holding down the "." will open up a series of pre-created URL endings.
5. Swipe left on a text to see the timestamp.
You can see the exact time that you texted someone back and how long it actually took them to reply to your message as well. In a text message, simply swipe to the left to see the timestamp of an exact text.
6. Save battery life by turning off your Location Services.
If you're not using maps at a certain time, why not just turn it off completely to save that much-needed energy on your phone? To do this go to Settings> Privacy> Location Services, then choose which app's location you want to turn off.
