How long does it take for my iPhone 4 to charge?

I was wondering how to properly charged my iPhone since I want it to last for long. I charged it on because if I turn it off, it will suddenly turn on. So how many hours does it take to be fully charged? And in what percent should I charged it? And please tips on how to charge it properly!

Being a 4 it depends on usage and charging frequency.hard to tell. You could have your 4 next to another one with almost same apps and data and one will still run out before the other.
If you can, it's best to recharge at 20% or below but not 1 or 0% if you can help it. Google phone lithium ion batteries.
For best and longest lasting charges--over time--reduce chance of having to change battery, you need an app for that.
There's plenty of them. See this example.
Best luck.

Usually w/ an iPhone, it won't take too long. But usually it takes around 2-3 hours, maybe less. But anyway, it's best to just use it until it's at/less than 4% (or even dead all the way) …& then you charge it all the way to 100%. Don't unplug it at all while it charges from really low to 100% for best results & it should last longer. Hope I helped

  • Why does my iPhone 4 take so long to charge? Okay so I just got a new iPhone 4 so I'm not sure how long it should take to charge but I just had it at 86% and I left it charging for 1hour and its still not full charged. Should I upload that IOS7 thing? Would that help? Also it seems to die really fast is that normal?
  • How long does it take an iPhone to recharge after it had been dead a long time? My cousin just gave me her old iPhone 5. It's in good condition but it's been sitting in her drawer for months.

  • How long does your Android/iPhone take to charge from 0-100 percent? What is the model and brand of your phone? What phone charger is it? Is it quick charge, vooc or ordinary charger etc? Is the device or screen turned off?
  • How long should my iPhone take to fully charge? So my battery life was on red and than I charged it and it's been 3 hours and it still has like 30% to go. Is this normal. Plus I can't open my iTunes on my computer it's said windows installing for 3 hours. My iPhone is new if that matters.
