How long to update my iPhone?

So, I have a regular ol' iPhone 4, and I still need to upgrade to iOS 6.1. I mean I've meant to update it but I always forget to.
How long should it take, I'm running 5.1.1 I think. Should I just have it update over night?

Every week ~

It takes about 15-30 minutes I think. That's how long it kinda took to update the iPhone 3GS.

It will just take a couple of hours, that's it.

It took 20 minutes to do mine.

  • Why isn't my 10 ft long charger not charging my iPhone after the update? Ever since the ios7 update, every time I plug in my 10 foot charger (not made by apple), it won't charge and says that "this accessory may not be supported." It only charges if I leave it untouched for long periods of time. When I plug it in at night it is only at %70 when I wake up 7 hours later. My friend has the same charger and has no problem with hers. Any suggestions?
  • Why is my iPhone taking to long to update? In the settings my phone said I have the IOS 7.0.6 update and I tired to update it last night and when I went to bed it was in the same place then I wake up and it hasn't moved does anyone know why its doing this?
  • Why does the iPhone 4s take so long to update to 7.0.6? I decided to update an iPhone 4s that I just bought the other day to 7.0.6 and it says its going to take 4 hours to update. Is this normal? I've never had an iPhone before so I'm not sure.
