My iPhone has started running really slow?

Even typing this message, it's struggling to match my typing speed. It's been like this for three or so days. It won't load up soundcloud cause it always crashes and I can't see videos on snapchat because it plays them at like 1 frame a second haha
What can I do to fix this?
I deleted apps and stuff I don't need and have nearly a gig left of memory.

I have a 4S running the latest iOS 7.
What even causes this? It used to work fine even when I had like 100mb left

Have you tried restarting the phone? Sometimes, random errors happen out of no where, and a reboot usually helps. If that doesn't work, then you may need to start fresh again.

BTW, is your phone jailbroken? If it is, some tweak may be causing this.

You can do a hard reboot - search online for reboot or reset iPhone.

Also - have you cleaned out Safari and deleted all the old stuff from searching? I hadn't done that in awhile and it made a huge difference.

  • 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!
  • My iPhone 6 has started to bend and apple won't replace it? I've had my iPhone 6 for almost a year now and its starting to bend slightly like those phones at bendgate. I still have warranty and insurance so I took my iPhone to apple to show them my bend and they won't replace it because they are saying its physical damage. What should I do i don't want to keep this bent phone.
  • My iPhone 5S has recently started heating up very fast? For example, I would use it for a few minutes and the back (where my hands hold the phone) would be VERY hot. I also put it to charge last night and when I woke up, the back was, again, extremely hot. I was afraid it would catch on fire or something. This has been happening for about a week now, and this has never happened before! Also I'm very good at preserving battery (I close running apps, turn of location services, etc.) so I'm not sure why it's happening. Advice?
  • My iPhone 4 is running so slow? Ever since the ios6 upgrade my phone has been running super slow! Everthing takes so long to load like if I'm uploading a pictures or just refreshing twitter or even using the Internet it has been taking so long to load anything I even deleted apps and its still slow what can I do to get it back to normal again?
