My iPhone is running slow. What most likely is the cause?

The memory is filling up, or you have lots of tabs open, or it's gotten to hot or it's to old.

Cancel out other apps that you don't use. Programs running in the background can make your iphone slow. If ios 7 double tap home button and swipe up the stuff you don't use. If on ios 6 and below double tap home button and tap and hold on 1 app and it will all wiggle and tap the - button to make it gone from the background.

Are you using iPhone 4/4s that installed iOS7?

If that's the case then follow my instruction:

1. Click on Settings
2. General
3. Background App Refresh
4. Turn it off
5. Back to general
6. Hit Accessibility
7. Hit Reduce motion and turn it on
8. Go back to accessibility and turn off Increase contrast
9. Hard reset you iphone by hold the power button and the home button at the same time (hold it until it's off).
10. Done!

Close your background apps as most just open stuff and never close them

  • Will my iphone run slow if i use up all/most of storage capacity? I got a 32 GB iphone 5. If i put all my music on there + all my apps, pictures, and videos, ill only have about 1 GB left. Will this slow down my iphone at all? What if i end up using all the storage? What's a good of amount of storage to leave free in order for performance not to be affected?
  • Will it most likely be crowded to get new iPhone 6s Saturday or sumday? I cracked my iPhone 5s yesterday (Thursday) and now I can't even see what I'm typing. I was going to get the new phone when things cooled down at the apple store but now that I have a cracked phone I want to get it as soon as possible. So will it most likely be crowded this weekend?
  • Why the hell is my NEW iPhone 4S running so SLOW? I got it a little before Christmas, it was brand new, AT&T 4G. It wasn't like this before! I barely have any apps, I have almost FULL bars and Wi-Fi connection, I don't know what's going on! When I'm on FB, it runs incredibly slow as well as on the internet. All I know is that it's p*ssing me off!
