What is RAM?

RAM stands for Random Access Memory, also known as volatile memory.

The RAM available in your iPhone helps keep the phone running and it’s what lets you play games, watch movies or perform any task without a drop in the iPhone’s performance.

What does clearing the RAM or memory do on an iPhone?

While it’s not widely spoken about, clearing the RAM or memory on your iPhone when the device is lagging or slow will give it a boost in performance by shutting down unnecessary apps that are consuming a lot of RAM. 

When you clear the memory on an iPhone, there will be no difference in the OS or the user interface, instead the speed at which your iPhone can compute tasks will improve and will provide you with a better user experience.

Free up Memory using AssistiveTouch – iPhone X and Above

On newer iPhone models, you are allowed to reset the RAM and memory by using the AssistiveTouch feature since there’s no physical home button on the phone.

But in order to do this, you will first need to enable the feature on the iPhone. 

Here’s how you can free up memory on your iPhone using AssistiveTouch

Note: This feature works only on iPhone 13 mini, iPhone 13, iPhone 13 Pro, iPhone 13 Pro Max, iPhone 12 lineup, iPhone 11 series, iPhone XS, XR, and X.

  • Start by opening the Settings app on your iPhone and then navigate to Accessibility

To clear the RAM, when the iPhone is on the Shut Down screen, tap on the AssistiveTouch button and then press and hold the Home button for a couple of seconds. 

The iPhone screen will now flash. Once this is done, you will be taken back to the lock screen and your iPhone’s memory will be wiped clean.

To check if you’ve successfully cleared the RAM on your iPhone, tap on any app from your App Menu.

If the app takes a few seconds to load, then the memory has been wiped successfully and all the background tasks that were consuming RAM have been closed.

Free up Memory using Home and Power Buttons – iPhone 8 Plus and Below

On older iPhone’s, you wouldn’t need to have the AssistiveTouch installed to clear the RAM or free up memory.

In fact, the process on older phones is actually much easier than the newer models and all it takes is a physical home/menu button.

Note: This method works only on iPhone 8 and 8 Plus, iPhone 7 and 7 Plus, iPhone SE, and iPhone 6s, 6s Plus, 6, and 6 Plus.

To free memory on older iPhone models, follow these steps.

  • Press and hold the power button until the “Slide to power off” toggle appears on the lock screen.

FAQ’s

How do I check the amount of RAM on my iPhone?

Switch on your iPhone and launch the Settings app. Now navigate to Device followed by System to view how much RAM is in the phone.

Why do iPhone’s have low RAM?

This is because the iOS memory is handled by the apps themselves and not by the operating system.

So, memory is automatically allocated depending on the application that’s opened unlike Android devices where the OS handles the RAM.

Takeaway

These are the steps to clear iPhone memory. After doing so, your device will run smoothly sans any lag.
