Possible Causes of iPhone Slow and How to Speed It up When Your iPhone Is Too Slow

Solution 1.       Restart the iPhone that Has Run Too Long

When your iPhone runs for a long time without any rest, the touch screen can become rather irresponsive and the computing speed can get less quick as well.

Solution: Reboot your iPhone. Press and hold the sleep button until the power off slider appears. Slide it to the right and wait for your iPhone to be shut down. When finished, wait for a while and then, press and hold the sleep button again for around 5 seconds, and the iPhone will restart.


Solution 2.       Check Whether Your Device’s OS Is up to Date

In some cases, an old iOS could be the factor which affects your iPhone speed.

Solution: Update your iPhone to the latest iOS version. Check the iOS version by going to Settings, General, and Software update. Read iOS Update Tutorial for more detailed information.

Warning: If your iPhone is too old, for example – iPhone 4, the update may slow it down as well.

Solution 3.       Shut Down Extra Open Applications to Make iPhone Run More Quickly

Some running Apps in the background can take up large space which also makes your iPhone run slow. Select those unused running Apps and stop them is the best choice.

Solution: Double tap on the home button on your iPhone and bring up the App list. Swipe upwards to close them once for all!

Solution 4.       Too Many Cookies and Junk Files Slow Your iPhone Down

When using Apps or scanning some web pages, cookies and junk files are generated, and over time, they get accumulated which dramatically slows down your iPhone. If you are still asking “Why is my iPhone so slow”, this should be the most possible cause! 

Indeed, iPhone has some inbuilt cleaning features for files like safari cache and App data.
