It will shut off when it's dead at about 1-2%. Sometimes it goes dark so many seconds after inactivity. I don't know. Have you done a full deletion network reset? What have you done?
It's possible that this is caused by the iPhone's own internal allocation settings - which is an issue that I recently experienced. It's easily solved: Settings - Safari - "Clear History". When the phone realizes that you're close to meeting/exceeding the maximum storage for "temporary internet usage", it will shut down - which is an indicator that you need to clear your internet history..... I'm not sure why this isn't at the top of the "iPhone Tips & Tricks" list - but it fixed my issue, nonetheless.
Hope it's helpful to you!
Mine did the same thing this morning.??? I plugged it in and it is still black screen. I dont know if there is a way to resett it or not.I will keep checking back to see if anyone has answers.
My phone as well did this last night. Power level was at 60%+ and the time differential was only about an hour, between use & brick. I will be looking over the Apple forums till I can get to my local , but this seems to suspicious, since the "new" plans go into effect today, thus potentially ENDING my family's unlimited plan that we've had for YEARS.
This sounds like a very interesting suggestion, however I do have one question that I would like to have you answer since you seem to know a bit more than my 20+ years experience in dealing with computers/technologhu -- how am I suppose to do this process that you've suggested when the phone will NOT power on???
I eagerly await your reply.
There was no implication as to my knowledge vs yours. I understand that you're frustrated; you've obviously come to this forum in search of possible solutions - which is exactly its purpose. There's no need to attack me because you're upset with the situation.
Now, as I said previously - I'd recently experienced the same situation. What I didn't say (as there was no demonstrated need or benefit) - was that I actually spoke with an Apple technician who instructed me to hold the buttons in order to power the phone up. Believe it or not, it powered on. I then went through the steps to delete Internet history (I later cleared cookies & cache as well) - and my phone resumed without issue.
I now perform this "clean up" step monthly - and have not had the issue again.
If this suggestion didn't help you, my apologies - but again, ONLY a suggestion. There was no intent to insult anyone's intelligence.
AUteach, I'd suggest that perhaps you'd benefit from a quick lesson in forum etiquette...but will refrain, as I feel you'd also be insulted by that.
To other forum members - I know the suggestion seems far-fetched, but it absolutely solved my issue. I hope it will help you, too.
