There’s no need to open Safari or another Web browser to search for something online.

For a quick way to top up, turn on Airplane Mode as you charge.

iphone tricks - get more storage spacevia iPhone

Get more storage space

Want to make the most of your iPhone’s storage space? Clean out your phone’s RAM, which reduces the amount of space your apps might be taking up. If you have an older iPhone with a home button, this is quick and simple: Just hold down the “power” button, wait until you see the option to slide and power off your phone, and then hold down the “home” button.

For newer iPhones with Face ID, there’s an added step. First, turn on Assistive Touch in Settings by going to Accessibility, scrolling down to Touch, and toggling on Assistive Touch. Next, hold down the “power” button and the “volume up” button until you see the option to slide and power off your phone. Tap the Assistive Touch icon (a gray circle), then hold the “home” button. If you still need more space, try to factory reset your iPhone.

Correct Siri

If Siri says something wrong—such as a name or an address—correct her by responding with, “That’s not how you pronounce…” and Siri will ask for the correct pronunciation.

One-handed texters, try moving your iPhone’s keyboard closer to your left or right palm by holding the emoji button and selecting one of the keyboards on either side.

Learn these simple iPhone shortcuts to streamline everyday tasks and save a ton of time.

Lock the camera’s focus and exposure

Try holding your finger on the screen until the “AE/AF Locked” box appears at the top of the screen. Now, the camera won’t lose its focus or exposure settings, no matter which way you twist and turn.

iphone tricks - Record a video and take a picture at the same timevia iPhone

Record a video and take a picture at the same time

To snap a photo while filming a video, just press the shutter icon next to the video button.
