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.
