How To Enhance Your iPhone’s Performance

Posted on February 16, 2019 in How To


Often times we forget that our smartphones are tiny portable computers. Just like computers there are settings and actions that can be taken to maintain the device’s performance.

Have you ever experienced your iPhone randomly powering off for no apparent reason? This can occur when there’s not enough memory (RAM) available to run iOS. Apps cache information to RAM and when it gets “full” there’s nothing left to do but shutdown. Periodically clearing out the cache can help you avoid headaches like slow performance, unexpected shutdowns, and App crashes.

Clear App Data

You can clean out App data by heading to Settings > General > iPhone Storage. Swipe through to see what Apps are using the largest amount of space.

Tap on the App to manage – Offload the App if it is not regularly used or Delete if you want a fresh start. ONLY DELETE IF YOU HAVE PASSWORDS AND OTHER INFO BACKED UP – ALL DATA FROM THE APP WILL BE LOST!

Delete App & Data

TIP: Get rid of unused Apps by Enabling “Offload Unused Apps” – your device will automatically uninstall the App and save data of less frequently used Apps to save space.

Clear Safari Cache

Clear Safari History

Web browsing is a huge cache hog! Bits of information are saved from every website you visit. In theory this is supposed to help pages load faster; however, it can lead to problems if not periodically cleaned up.

Tap on Settings > Safari > Clear History and Website Data to remove browsing data. Be aware that if you are using iCloud to sync Safari between devices, data will be cleared from all devices!

Quit Apps

One of the easiest ways to free up some memory on your device is to quit open Apps. Do this by either double pressing the home button and swiping up on the App windows (iPhone 8 and earlier). For iPhone X and later swipe from the bottom up half way and over for the app switcher interface. Then swipe up on the App windows to quit.

Battery Performance

An old battery can degrade over time and also cause performance issues. Learn more about how to check your device’s Battery Health from our earlier post “iOS 11.3 Update Adds Battery Health in Settings.”

Power Cycle

After clearing caches and removing unwanted documents and data from Apps, it’s a good idea to power cycle your device to clear any remaining bits of data stored in RAM.

For iPhone 8 and earlier: Hold down the power button until “slide to power off” appears on the screen. Swipe to the slider to the right to power off. For iPhone X and later: Press the volume up button, volume down button, then press and hold the side button until “slide to power off” appears. Swipe to right to power off.

Tip: You can also power off from Settings > General > Shut Down


If you followed the above steps and are still experiencing performance issues there could be an additional software or hardware issue with your device.
