iphone lagging

"Please can someone help me with my iPhone X lag. The keyboard gets stuck when using any application. The screen keeps shuffling without any reason." -- An iPhone X user

We have all suffered from the iPhone lagging problem. The phone reacts to our taps and commands after seconds of pauses, which post a huge challenge to our patience. Now, with the following 10 all-around tips, you don't have to tolerate the lags anymore. After conducting these, your iPhone will run significantly faster than before.

Part 1. Delete Files to Fix iPhone Lag

One of the most common culprits for the iPhone lags is the lack of storage. To free up more spaces on your iPhone, deleting some large files proves to be effective. Though some files may seem small as individual files, they exist in large quantities. These files include images, audio, and videos. After deleting these files, you will be amazed at how much space has been freed after their removal.
If there are videos or photos that you don't want to delete when there is not enough space on your iPhone, back up them to iCloud, so that they can be kept without taking up your iPhone's storage. The automatic sync feature can be turned on in "Settings" > "iCloud".

Part 2. Restart iPhone to Fix iPhone Lag

For lags caused by too many apps running at the same time, a restart would be a quick fix, because it would make all the apps shut down instantly on your iPhone. While a normal reboot should be good enough, you can still try force rebooting the phone to give it a more complete restart, though it is not recommended to do so very often. We have enclosed a force restart tutorial below for your reference.
