How to start my iPhone after "overcharging"?

Theoretically that is not supposed to happen, because the power circuit inside the iPhone is supposed to have a relay/switch that detects when the charge is complete and no longer needs new current. So I would be a little worried about whether the power management pieces of your phone are working properly.

All of that said, I don’t have an answer. MY guess is that time will use up some power and eventually it will turn on.

The snarky response would be “You were overcharged the moment you bought the Apple product”.

Are you sure that the phone charged? If the cable stopped working – which mine often seem to do – the phone may be out of charge completely

@Stinley Will check but this has happened before.

Solved it. Stopped by the AT&T store and they had the magic touch.

@janbb – what did they do? Post it so others can learn.

Held down the start and the home button just as I had been doing but I guess he did it harder or longer. I have had that work for me before but it didn’t work this time. He said there’s nothing wrong with leaving the phone on the charger overnight and nothing wrong with the phone – stuff just happens (to coin a phrase.)

It’s really surprising how that one move works for just about any problem you can encounter with an iPhone (other than a physical defect in the phone which should be covered by warranty.)

One time I thought the battery had completely died altogether (this is on my iPhone 3G after all) because of a kink in the charging cord which interfered with proper charging.

It took a week or for me to get a replacement cord. After charging overnight, it would turn on briefly and immediately shut down again.

But I kept doing the same move of holding down both buttons even tho it promptly shut down a few seconds later.

I must have done this about a half dozen times or more. And voilà, it finally sprang back to life.

It never ceases to amaze me how many times that one simple maneuver has saved my aging phone.

BTW: I doubt your phone was overcharging because Apple has designed it to prevent that.

IF it had been overcharging tho, you should be eligible to have it replaced because that’s a serious defect (Apple’s fault).

Anyhow, glad you got it resolved.

Yup and thanks. I thought I had tried the maneuver many times but apparently it took one more. And the techie also said they don’t overcharge.

@janbb what you did is called a “hard reset”

When you press both buttons till the apple logo appears your iPhone preserves your personal data then tests and reconnects all the firmware connections.

If an app is hung up (often causing a black screen) it force exits the app and the screen will again turn on.

@Dog Yes, as I said this has happened before but this time multiple tries didn’t work.

If you are close to an Apple Store they will run diagnostics for free.

Thanks!

Hey Doggie, good to see you around :)

I have an iPhone 5, not a 5S, and no, you really can’t overcharge it.

When you held the home and start button down did you wait for the little white Apple logo to appear on the screen before you released the buttons? I’m not sure but I think you have to wait for that and then release the buttons
