Iphone 4 suddenly very slow?

I know this phone is dated (iphone 4) but I'm really tryin to wait & see what apple is gonna do next. I updated towers last week (*22899) last wk and now it's worse. The whole phone is slower, but safari is worse (3G is terrible, wii fii a little better). I'm using 8.2 GB & have 5.5 GB left. Any advice, tricks, ANYTHING at all will be appreciated! (Don't want to hard reset just yet.) This is what I've tried beside tower updates: minimal location services, constantly close apps, soft resets, clean safari history & cookies, & delete messages/calls/voicemails.

3G depends on your carrier. On other things make sure you close all apps open in the background.

  • Why do I do this? I'm very very very tired yet I don't want to sleep? I want to sleep because I'm practically blinking and bobbing my head side to side like a drunken man but I just don't want to sleep. I watch tv or go on Facebook or play on my iPhone. And I'm starting to get dark circles. And as a guy I don't wear. Concealer or whatever
  • My iphone screen is very dark, but if I look very close, I see the apps slightly? My iphone screen is very dark but I still see the buttons slightly, but I have to look very closely in order to. It is definitely not the brightness, because the brightness is set to 100% and its way too dark anyway. I tried restoring my phone and turning it on and off, but nothing is working. Please help. What do I do? I literally threw it out of anger and its fixed.
  • My iphone 4s is charging very very slowly? I let my phone charge for about three hourse and it only charged from 3% to 5% and its really really slow; i'm not sure if its the battery or not. Also; i had finally charged it to 10% and i took it off the plug for a second the. It went back to 1%.
  • My internet is being slow suddenly? I have a fast Wi-Fi. I just got from school and I can't load videos, even advertisements. I'm so dressed… I feel so furstrated i wanna break my iPhone. What can I do
