New iPhone 4S unresponsive, requiring a hard reset on several occasions

See https://discussions.apple.com/thread/3402128?answerId=16433465022#16433465022

I have same problem. Last 2 nights I have left my phone unplugged and woke to a dead iPhone. Unresponsive, out of power. Tried plugging it in, but it needs the reboot to get a response. 16GB 4S on AT&T. My mom has a 4 on iOS5 and is not reporting any problems...

Same problem as uskrums.. happened to my twice for the 16GB AT&T iphone 4s. Put my phone on standby and after two hours the phone shuts off. Last night happened to me again and it shut off again, only hard reset will turn it back on? Hardware problem or Software problem!?

I am glad I am not the only one having this problem. The first time it happened to me was two days after I purchased the Iphone 4S(ATT 16g). It has since happened three times in three days. I am quite annoyed. I never had these problems with my 3G. I am going to return it and get another.

I left mine plugged in charging last night and it is the first night that it has not died.

Yesterday I had my third lockup in as many days - again, it happened at the same time, between 10:30 and 11am.

Called Apple support and they suggested restoring as new (not from backup) and seeing whether the problem recurred. I did that around 2pm yesterday -- 24 hours later, I haven't had another hang yet. For now I've not restored any of my applications, music or email accounts, to try to narrow down what caused the problem.

If it's still working tomorrow, I'll try restoring things one by one and see whether the problem comes back.

add another 32gb iphone 4s

warm to the touch, and nothing, my diagnostics says i had low memory, on call to apple now though

Hi everyone,

This is happening to my new 16gb 4s as well, about once a day since Monday.

I restored it from an iTunes backup of my 3GS...

Has anyone had their phones jail broken in the past? mine was, but was not when I made the backuP I restored my new phone from, maybe that has something to do with it?

Same exact thing happened to me today. Went to a meeting w/ 96% battery. Left the 1 hour meeting. Phone was on the table the whole time. Took phone out of sleeve to snap a picture and wouldn't power on. It was warm to the touch. Called Apple support and tried all kinds of hard reset and nothing happened. A few hours later tried to do another hard reset and this time it worked. Took it to the Apple store later that afternoon. The rep said - "oh, it's because I had too many apps open." Huh? She told me to explicity close all apps in the multi-task bar (double-click home key) because in her experience, too many apps there will cause performance to degrade. I've never had to explicitly close apps. When I switch from app to app, I always just press the home button. Never had this happen to me with the 3GS and I NEVER explicity closed an app in the multi-task bar. Does not make sense. Now, we have to close apps? The rep ran a diagnostic and said the phone was fine. I just have to reset when it happens Is this what I have to expect? Besides,earlier today, I tried to reset and it wouldn't do it. Had to wait several hours.

I hope Apple does something about this.

I got my 64gb 4S three days ago.

Yesterday the phone became unresponsive twice requiring the cold reboot sequence.

Both times when the phone came back on wireless was 'off' (wouldn't see any known nearby wireless hotspots) until another 'normal' shutdown and powerup (normal reboot) was performed.

Then everything worked again.

Battery life has been a concern as the device is on a charger all night. Removed from the charger at 0530 am and by 1630 is down to a third (roughly) remaining.

Wireless is always enabled but not always connected, Bluetooth is not on. Siri has only been used one time since new.

The phone was 'restored' from and replaced a 16gb iPhone 4.

Good morning,

16Gb iPhone 4s running on AT&T became unresponsive this morning. It was restored from a 16Gb 3Gs config. It has been running fine for a week until this morning. Normal operations prior to unresponsive black screen; listening to music through Music app, received a message in iMessage, locked screen and put phone in my pocket, paused music with earbud controls, and when I tried to unpause the music with earbuds, nothing happened. I took the phone out of my pocket and screen was black, phone was not warm as others have reported, but only thing that brought it back was holding down the "home" and "lock" buttons at the same time. It's annoying, but it worked.

Does Apple monitor these forums? Or should I/we call the number previously reported so that they know the extent of the issue?

Scrabblepez, what that Apple employee told you was BS!

We can add another 32gig 4s to the party and I can tell you it has nothing to do with too many apps open because I am one of those maniacs that closes everything and never has more than 5 apps open at a time.

I get a lot of "app crashes" as well and I can confirm from my system logs that I've got a "low memory" log entry at least twice a day and some days as many as 6 since activation Saturday!!

***I believe this is a memory allocation issue...We saw this over on the Android forums (I'm a staffer there...shhhhh ;-)) with some HTC devices running Android 2.1 and 2.2. I cannot imagine that Apple is not yet aware that we have a memory leak or memory allocation issue. I also find it completely nuts that I am anal about resource mangement and I still get all those low memory log entries!!

I have a genius bar appointment tomorrow at 10am and I will update after!!

Hello, I have an AT&T 32gb 4S. Several times since I bought the phone, I have had issues where Siri does not respond, the wifi stops working, the settings app crashes, and the only way to turn off the phone is to hard reset it, then when you do reset the phone, it looks as if it was showing a completely inaccurate battery reading prior to reset. I have reason to believe that all of these issues are correlating with the same problem because once the phone is reset, everything works like normal.

Glad I'm not the only one seeing this!

Went to the Apple Store yesterday and had my 32GB 4s replaced. So far no more issues and phone feels* like it is running cooler. I think there may be some that are software related and an isolated few that are hardware related.

My new 32gig iPhone 4s arrived from AT&T yesterday afternoon. I removed it from the box, turned it on, saw the Apple logo, then looked away for a few seconds to start up iTunes on my PC. When I picked the iPhone back up, it was unresponsive (dead). I plugged it in, figuring the battery was dead. An hour later, I pressed the power button and it started booting again, successfully this time so I restored from my 3 GS from iTunes. This morning, it went unresponsive in my pocket. I logged in here and discovered this thread and how to do a cold-restart.

So it's gone unresponsive twice in 2 days, once right out of the box. The only difference for me is that it does not feel warm to the touch while it's dead.
