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

I'm probably a bit late with my advice but I just solved my charging problem by removing some lint that got in the charging port. A quick firm blow did the trick.

As with any electronic device with an OS, there has to be a certain amount of juice in the battery to safely start the OS. Let's say it turns on immediately. If the phone accidently is unplugged before it boots up completely, there may not be enough energy to continue booting up and cause a shutdown at the same time; thus causing damage to the phone. Apple has set a limit to start the phone once the phone has been charged to an arbitrary limit of 5 percent to avoid this damage.

Since you are connecting to a computer, the power has to go through the computer first before it gets to the phone. It's like with anything with a middle man. Everything is faster when you go to the source.

It takes my iPad like at least ten minutes idk why everyone on here is saying we're impatient or that we should charge it before it dies but like sometimes I just forget that it's low or it dies while I'm not home. I agree that it is inconvenient apple should speed that up somehow.

It's important to note that if the battery is extremely low on power, your device may display a black screen for up to two minutes before one of these images appears. Continue charging for at least 30 minutes, or until your device is fully charged.

Hi I have a iPhone 5c in green and I love the phone however there is one downside so far I've detected. The iPhone 5c takes a long while to come on to the unlock screen and this is with a full battery . This is after I turn the phone off then come back in a while to turn it back on. It's a annoyance. But from reading the other posts this seems like an Apple glitch with their phones. I also have an LG enact smartphone and that comes on automatically. Maybe someone needs to notify Apple of this issue as it seems I'm not the only one having this problem . Thoughts?

LOL yeah i can grow a beard before blackberries start up

We'll my ex brother in law says that if you charge your phone when there's still juice left you are actually frying the battery a bit each time u do so. He's great on electronics so I trust his advice

He is wrong.

Not so much on batteries though.

Lithium Ion batteries are not designed for deep cycling (full disharge). Doing so is far more harmful than charging them whenever.

-> Battery University - How to Prolong Lithium-based Batteries

"Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full dischargesand charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while. "

Any specific reason you are turning it off?

This seems like laziness on apple's part to me.

When the device is plugged in and charging, there could and should be circuitry within the device, that powers the device while it's charging.

Huh? You can use the iPhone while it's charging. In fact, if you turn it off and then plug it in to charge, it will turn itself back on.

This thread is about the ridiculous amount of time one must wait (I waited about 30 mins today), once their battery is dead for the device to be usable. Currently, one must wait until the battery reaches a certain level of charge before the device boots up.

What I am saying is that the device should be usable the second the phone is plugged in, regardless of the amount of charge that the device had on the battery at the time it was plugged in.

All of this is doable with circuits and code.

It may be doable but I've never seen a smart phone that does it. It would also probably require a back up battery. As it is, there's barely room for all of the stuff that goes into an iPhone. An additional battery would displace something more useful.

No additional battery.

Parallel circuit with a voltage regulator to power phone on one branch and current to the battery on the other.

Once the battery has enough juice, turn off the voltage reg branch and let all current go to charging.

The fact that other smart phones don't do it simply presents an opportunity for Apple to be the best at yet another thing.

Why don't you build your own phone?

Walk the walk, don't just do the talk.
