Random Shutting Down of my Phone

I am new to the Tour, so if this is something that happens and has been known, sorry. My problem is that my phone will decide on its own to shut down out of no were. Is there something that I can do to keep this from happening? Is it just my phone?

Mine does this too. I am getting my 3rd tour on Tuesday, the first one never did this, but the trackball was horrible (left to right) also it had a ridiculously loose battery door. My current one reboots itself 5 times a day and the trackball is garbage. (left to right again)... also this one has the "screen ripple" issue, the first one did not. good luck getting on that works, one of my coworkers has one.... the other one has the same issues as myself. Welcome to the tour family, get to know your carriers store clerks, you will be visiting them often.

My iPhone with 40 or so percent randomly shuts down with iOS 7 and 6. Often with the camera app stating the phone is out of battery. Moments later I turn it back on and the same battery life still appears.

My iPhone with 40 or so percent randomly shuts down with iOS 7 and 6. Often with the camera app stating the phone is out of battery.

I think you might get a new phone instead of repairing it as it takes time and you said the repairing center is far from your living place

Macbook Pro Randomly Shuts down...SMC Reset only temporarily

I have a somewhat concerning problem with my 2011 Macbook Pro (15").
It started two nights ago, didn't happen yesterday, and happened again today. It has also fried two iPhone chargers. Here's the story:
On Sunday night, my Macbook randomly shut down. Wouldn't restart, nor would it even charge (the LED on the charger didn't even come on). So after trying everything I could (namely, PRAM, SMC, etc.), I finally took the bottom of the computer off, unplugged the battery internally, did a hard reset of the SMC, and everything was back up and running. That night, I got a strange error when I plugged my iPhone in to charge: USB is using too much power and has been disabled, or something along those lines. Weird--but my computer didn't shut down again, so I shrugged it off.
Fast forward to tonight--all worked fine until I plugged a NEW iphone charger into the computer. This same cord worked fine this afternoon, but I got the "USB drawing too much power" message and then nothing. The computer shut off, had to unscrew the bottom and do another hard reset, and here I am.
I've tried to figure out just what might have caused this. I did buy a charger from my university's bookstore that I do not think was Apple branded. Is it possible that it somehow fried my battery? Or do I have a bigger issue - motherboard, RAM, etc.? The computer (when I get it to finally power back up) works fine and no files have been lost, so I don't think it's harddrive related.
If anyone can shed some light on this problem, please let me know. I've searched for a long time to find a problem similar to mine and haven't found any answers other than the generic "Reset SMC," or "Reset PRAM." I know how to and have done both of these things. Do I need a new battery? I ordered a charger directly from Apple and have only used it since the first shut down.

There's only a limited amount of things you can do on a laptop repair-wise: tiny and tightly packed components are a far cry from yesteryear's huge boxes with individual removables.
Is the USB error coming in regardless of which USB slot you use? Have you reproduced this error with other USB devices that draw a charging current or significant power?
If the problem is indeed that USB is drawing too much power, it could be a short in the USB circuitry, or it could be a short with your phone. Try charging someone else's iPhone. The concept with current is that it's "pushed by voltage" and "drawn by a resistance in a closed circuit." If the voltage is too high, or if the resistance is too low (short circuit), then you will end up where you're at.
Also, it could be helpful to review your system log. In spotlight, write "terminal" then type in the shell prompt (without the quotes) "cp /var/log/system.log ~" this will put a file on your desktop that you can open with a text viewer, search for the word "USB" towards the end of the file, and see what you can make of it. Post anything here that seems suspicious. Warning: it'll be cryptic and hard to read!
So,
- Try different USB slots on your computer
- Try different USB power-drawing devices
- Try different iPhones or iPods
- Review the system log and post any suspicious lines

Another iMac Randomly Shutting Down!!

Hey Everyone. I'm new to the forums, though i've always used them as a resource over the years to learn more or troubleshoot issues. Hopefully, now, someone can help me with mine personally.. :-/
I have an intel 2.8gH Aluminum iMac that I purchased fall of 2007. Only now, almost 2 years later is it suddenly (just started yesterday) turning off randomly. Everytime it will not allow me to turn it back on until a minute or so has passed. I have reset the SMC as well as the PRAM several times. This afternoon, it is now to the point where I cannot even keep it running long enough to download an app to up the fan speeds. Although, I don't think it is overheating in the first place.
I'm really hoping it is just the power supply, as I've seen that be the fix for SOME iMacs i've found at other online forums. Though, the upper corner of my iMac is not hot or smelling burnt out at all. I have found more than several online forums of people complaining about their iMacs randomly shutting down, and am praying it is not the logic board, as that is a $900+ fix.
please, someone give me insight to how i can check if its the power supply or something else? I use this iMac for recording all of my music, editing video, and (of course) playing WoW lol. Currently using my 1st gen macbook.

I bought my iMac 20" in May 2006. I had been very impressed with it until one day I shut it down to move it to another room. I could not get it to turn back on. I had to leave it unplugged for a few hours. Since then it has started randomly shutting itself down, turning itself off and not starting up again until I unplug and leave it unplugged for a few hours. I had purchased the Apple Care? Extended Warranty, and the fault occurred during this three year period, though I failed to take the fault seriously and did not phone during the period. It was just after the three year warranty that I phoned Apple Care? about it and everyone I spoke to said they had not heard of this problem occurring. I wonder now, why the Apple Customer Service Team don't visit the discussions.apple.com where they will find quite a significant number of like problems occurring with the iMac sold in 2006.
My reason for paying the nearly triple price point for an Apple Computer was the quality of the build and my expectation that I would get far longer life out of my purchase. I don't like buying throw away products and I gladly save and wait longer to buy better quality products. Just as an example and point of reference. In 2000 I purchased a second hand Dell with 8GB HDD and 256Mb RAM. I paid $1000 for it and I gave it to my father when I got this iMac and he still has it running today. It has not had a single hardware issue in nine years. Good luck I suppose. However, after spending around $3000 on this iMac, and Apple now telling me the Logic Board is generically, non specifically 'failing', it goes against my pure desire for non disposable, throw away products to buy another Logic Board for AUS $1064. For one, I don't believe it has given me anywhere near the life that I expected from a product with such a high price point and solid reputation for quality, nor do I feel confidence in buying anything more 'Apple' after the dealings I have had with them over this problem. I am amazed that Apple would sell a 'failing' Computer to their customers and then expect that the customer will spend more money, considerably more, on a product that may be equally faulty and that they will not stand behind either.

My iPhone 4 randomly shut down and won't turn back on.

My iPhone randomly shut down whenever I got a phone call twice in maybe 5 minutes. Now it wont turn on no matter how many times I plug it in or use the home and lock button. Is there anything I can do? After the first time it just turned back on but now it won't.

I just had this happen. Hold the lock and home button down for ten seconds.

8x randomly shutting down

My 8x has been randomly shutting down as of about a week ago. I updated the phone, performed a soft reset and hard reset and none of that has helped. Has anyone else had the same issue?

Yes Geordan_Ganka,
I have an HTC W8 phone (WP8X). There appears to be no rhyme or reason for the shutdowns. Sometimes, I'll just reach into my pocket and pull it out, press the power button - and realize it's OFF, when it had been ON when I deposited it earlier. Other times I'll be actively using it (typically Pandora) and it'll just power-down - I do see the "Goodbye" screen. It doesn't vibrate or make noise when this happens and it's sudden. I would say the phone shuts off about once daily, if not more frequently than that. I refuse to use the phone as an alarm clock because of this and it has resulted in a multitude of voice mail, which I'm not pleased with as the phone is my only line.
Do these symptoms sound similar to your power-down issues?

Macbook randomly shuts down after installing Mountain Lion.

I have a late 2008 Aluminum Macbook; as of last week I have installed Mountain Lion finally and I've come across a rather irritating problem: the laptop keeps randomly shutting down. I've noticed it primarily likes to go down when the battery is at 89%. I've never had battery trouble before, this happens even when the computer is not over-heating, so I'm fairly certain it's not a battery issue. After restarting the computer all the applications I was using are still open and any progression I had made on documents have been saved since the time of the crash.
I'm really at a loss as to what's going on with this. Has anyone experienced something like this or have any suggestions as to how to fix this?

Hi ppl again :)
I found that screen is not disabled, it is only have a very low brightness. So I begin to wait because I saw that actually installer is still running. Finally, Mas OS was installed and after that I change brightness using keyboard (it didn't worked while installation). Now all is ok. I also tried to reboot and system loaded correctly.
I hope this will help. Unfortunatelly Apple support was unable to help me by a phone call.
Have a nice day!

IPhone Randomly Shuts Down

My iPhone randomly shuts down and I have to charge for a few minutes for it to come back on. Went to Apple Store tech support. They did a diagnostic and found nothing wrong with the phone. Told me that the problem was the number of apps running in the background (i.e., multitasking). After deleting all of the apps in the background, the phone still shut down with 53% of battery indicated. What is the problem? What can I do about it?

To be honest these are the solutions that may or may not work.
First thing I would try is rebooting the phone by holding the sleep/wake button and home button for 15 seconds until you see the white apple logo.
If that doesn't work I would restore from backup. If that doesn't work I would restore as new. If all else fails take it to your closest apple store they may replace the phone for a working one..

My 8310 randomly shuts down

I have my phone fully charged and it will then randomly shut down. The ONLY way to restart it is to plug it into the charger, the hourglass starts up and it takes a while to get back to "normal" .
I think the only constant I can pick up is that the phone does not shut down when lying static.
Please help

Hiya!
have you noticed any particular trend as to what you are doing when it is shutting down?
If it happens when using an app, try removing that app. if its a core program, I would recommend trying a Clean Reload of your OS using the DM and see if that gets it. Just make sure you backup first.

Help my iPhone 3GS randomly shuts down, what is wrong?, Help my iPhone 3GS randomly shuts down, what is wrong?

My iPhone 3GS randomly shuts down for no reason, and apparently I am not the only person having a problem with this. This happens regardless of how much battery life my phone shows, or whichever application I am using. IS THERE A FIX FOR THIS!!!!!!! I understand that cell phones are not built to last forever, but my phone is in to good of a condition to go out and purchase a new one.

Before you get your knickers all in a twist, try the basic troubleshooting steps Apple recommends:
Basic troubleshooting steps clearly outlined in the User Guide are restart, reset, restore from backup, restore as new device.
If you have been through ALL of the troubleshooting steps and you're still having problems, then you'll need to bring your phone to Apple for investigation.

My iPhone 4S randomly shuts down.

My iPhone 4S randomly shuts down, when plug it into charge. I restored, as a new iPhone and problem continues, what do I do? iPhone is 4 months old, and has no damage.

It's almost impossible to say whether it's the battery or something else. If you're running 6.0.1 and you've done a restore and set it up as new, there are no other software updates to try.
If there's no Apple Store near you, contact Apple Care. If you can't wait for a replacement phone, you may be able to get an express replacement (they ship you the replacement before you ship them yours, but they will put a hold on your credit card until yours is in their hands).

IPhone 5s just randomly shuts down

my iPhone 5s just randomly shuts down even though the battery is in 60-70% charged range.
It shows the battery icon with one thin red line, I plug it in to power and a minute later it comes on with battery in 60-70% range.
I cannot figure out what's going on !!

Try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again.
If this does not help, get your phone checked by visiting an Authorized Apple Service Provider or Apple Store next to your place.
You can also contact Apple Support and talk to them. They can check the battery online.
Or visit this page to do that: iPhone - Contact Support - Apple Support
Click on Apple Support, then on ->Battery, Power &Charging ->Battery questions and troubleshooting, and follow the instructions.

Iphone 5s randomly shuts down

Hey,
I have an iphone 5s that randomly shuts down. Made a genius bar appointment and was told I had too many apps running(!!!) and I should kill them all and all would be fine. Surprise surprise that didnt solve the problem. I took if back to the genius bar two days ago, they swapped the phone for a new one and I started again from scratch. No restore or anything I think is potentially corrupt-bar my apple ID all is completely new and clean. Re-downloaded all my apps from the store fresh etc. etc. A day later the new phone is doing exactly the same thing. This is driving me crazy!!
Anybody have any advice?

Ouuu... may be problem in ios7.1.2 because my iPhone 5s have this problem too (someone later after the update )!!! But I can't go in apple store because I live in Ukraine) If this problem really in ios 7.1.2 please tel me about this!!! No service in my town does not know what the problem is.
Sorry about my English
In my case I hope that will fix in iOS 8.

Why is imac randomly shutting down?

Hi everyone, My imac 24" intel (early 2009) 2.66ghz 4GB ram keeps randomly shutting down, It started after i upgraded to 10.8.1, It was running fine until then, I had the screen set to sleep if no one had used it for half an hour (not changed this for 3yrs) & it started to not wake up & i would have to restart then when i started using it would randomly shut down like someone had pulled the plug! When i got it going again it would do it again sometimes in 5 mins sometimes 10 mins, I spoke to apple on the phone did all the usual stuff they told me to do still the same, I'm going to the genius store tomorrow with the imac.
I have no idea what could be the problem.
Anyone had this before?
p.s I have had this 3yrs now so no warranty

HTC ONE randomly shut down now requires password to decrypt storage..

I have had my ONE for a couple of months and had MULTIPLE issues but this one takes the cake! I was in Wal-Mart and the phone randomly shut down with a full battery. It would never reboot on it's own so I had to push power down and volume down to get reboot screen. When it finally restarted, it came up with a screen that says "Type password to decrypt storage" or "place an emergency call". I never set a password so am unclear on what to do from here. Tried to factory reset but it doesn't work. Any advice??

That's pretty strange, dstenz50. It takes a few steps to encrypt a phone http://bit.ly/1kdQYgh and I haven't come across it doing the process on it's own. Has anyone had access to your phone? Did you previously set up a PIN or password to your device? What's the exact message you're seeing?
