Why does the iPhone take so long to start up after it dies?

I was wondering ,i have an iphone 3gs i was out of the house and my battery went flat i got back home and it usually takes about 3 hours befor it switches on , is that normal ? i mean what if i needed my phone for emergancies ?

It should take <10 minutes for the charge icon to come on.

No, that's not normal. Normal is 10-15 minutes.

You have to adapt to an imperfect world, just like the rest of us. Believe it or not, there was a time when no one had a mobile phone... somehow we made it through the day and all those emergencies. 😉

Think illl just put up with it till contract runs out 🙂 thanks for the fast responce people 🙂

A recent study has indicated that some types of lithium ion (lithium iron(II) phosphate) batteries do have a memory effect. Obviously it isn't as distinct as older battery technologies but it does exist.

My guess and experience is that while li-ion batterys have little if no memory effect, they do seem to lose performance over time. In both respects, that they seem to take a bit longer to charge, but don't last as long.

This exact experience most recently I have seen on a gen 1 ipod touch. It works, but if that battery gets way down it can be awhile to get it back into a operative state.

Paul, your response is totally off the mark. Think about why people are in this discussion.

I understand this discussion quite well but you completely misunderstood my post. I clearly stated that a 3 hour startup time was not normal. My comment about adapting was in response to his specific concern about not having a phone for emergencies, not about having to adapt to a 3 hour wait. It was somewhat tongue-in-cheek... I guess you missed that.

I have a iPhone 4 & just recently I have started running into this problem where when I turn it off or restart it, it takes almost 10 or more minutes to turn back on! does anyone know why? PLEASE HELP!

Shorty, please make a new post on the forum. Tagging onto an old thread is not recommended if you want to get help.

When you make the new post, include the following:

iPhone Model

Your carrier

Reset Settings (yes/no)

Usage patterns.

my phone died (4s) and it's been taking over 7 **** hours for it to even hit a charge so im guessing either apple *****, or it is my phone. it may be the genious bar but really 7 hours? even right now it still hasn't hit a charge

The phone gets charged to 5% before booting back up. This is so that it doesn't turn off immediately right after you unplug it. protects the flash memory from corruption. this is mere speculation on my part

Your problem is not relatated to the original (and now rather old post). You're more likely to get help if you start your own thread with a properly descripteve subject line. Also, lose the profanity. It makes your post difficult to read.

Best of luck.

If Apple (or Samsung) can design their devices to not boot up util power reaches 5%, why not design them to instead power off when they only have 5% left?

It makes sense from an operating system preservation standpoint.

Run as long as possible (safely) and then only boot when it can safely startup without being interrupted.
