3 Clear iPhone RAM
Generally, iOS does a great job of managing its memory resources. Apple designed it that way. But, with that being said, there are still instances in which your iPhone might feel a bit sluggish due to excessive RAM usage. Luckily, there’s a quick way to clear your RAM by hard resetting your iPhone.
On older iPhones with Home buttons, just hold down the Power/Wake button and the Home button until the Apple logo appears.
On an iPhone X, 8, and 8 Plus: press and release Volume Up > press and release Volume Down > press and hold the Side button until the display shuts off and the Apple logo appears on the boot screen.
