Is your iPhone being slow?
Older iPhone’s tend to be a bit sluggish but this simple trick will speed up your iPhone, and it takes less than five seconds!
Open up the App Store app and tap on any of the buttons along the bottom of the screen (Featured, Top Charts, Explore, Search or Updates) ten times.
The screen will flash white for a few seconds, and then return to the App Store homepage.
What this does is it clears out the App Store’s cache and makes it reload, getting rid of any frozen updates and temporary files – making your phone speed up.
It can also be used on the iTunes Store app.
Another tip to speed up your phone is to reset it (press and hold the home and power buttons together until the phone turns off and restarts), deleting apps you don’t use anymore, and turning off the Background App Refresh function (Settings > General > Background App Refresh).
