IPhone 3G shuts down when not plugged in

Hello,
I have had this problem for awhile and now just getting to troubleshoot the issue. Basically the phone appears to take a charge after it's been plugged in to my computer and/or outlet, however when removed it shuts down after 30 seconds or so and I have to reboot. Is this a battery issue or another underlying issue? Can it be fixed? I took the phone to the apple store but they were not any help due to no warranty. Thank you!

My 3G's problems have only gotten worse with each new update. Now I literally can't use it continuously for more than two minutes without a full charge going down to zero. I can basically just call people on my 3G and that's it. I probably need to get a new phone now, but with the iPhone 5 possibly coming out this year I want to see if the iPhone 4 (and iPad 1) will go through the same ordeal with iOS5.
I think Apple just needs to learn how to make their software more scalable and learn to support different versions of their OS simultaneously.
With so many models in use it's almost become the same as their personal computers. They shouldn't continue to just support one updated OS optimized for one specific model. Microsoft continues to update and support Windows at least one generation back from the current version because they know there are people who are going to own these things for four years at a time.

Shuts down when not plugged in

My new (got it in July) MacBook shuts down when it's not plugged in. I usually turn it on and it will last around 2-3 minutes before shutting off completely, then if I try to turn it on it will make the turning on sound and immediately shut down. If I plug it in it will stay on. I looked at downloading OS X 10.4.8 in order to download the suggested firmwire to help with this issue, but will that cause me to lose all of my photos and everything else stored on my computer? Could there be any other solution to my malfunction?
Thanks for your help!!

Hi -
When it's plugged in ...does your battery show a charge? Also, if you press the little button on your battery (on the bottom of the macbook) a series of green led's should tell you if you have a charge. just asking this because your macbook may not stay on if your battery is not charging/dead.
Yes, you should also update you system and firmware as well.

MBP shuts down when not plugged into wall

hey there,
was wondering if anyone has experienced this paritcular problem or knows what to do...
I've had my MBP for about a week now, and I just notcied a day that it randonmly shut down... but it was only once, so I though it wasn't that big of a deal. I left the computer charging all night ast night, and when I tried to start it without it being connected to the wall, it wouldn't boot. I checked my batter power, which is 89% full, reset the PRAM and reset all of my premissions, but it still shuts off everytime the DC adapter isn't plugged in. I aso ran the memtest program for RAM which someone on this forum had suggested, but it says that everyhting is A-Ok... What do i do? Somebody, please help!

I am having the exact same problem as you! The computer will run all day plugged into the wall, but after I remove power, it shuts down within 10-15 minutes. It usually refuses to start up again at all until you plug it back in, even though the lights on the battery indicate full charge. After plugging in and restarting, OS X still reports full battery charge. I have tried resetting the PRAM and PMU, and also cleaning the magsafe connections. Apple Hardware Test reports no problems.
I added a stick of Techworks memory from OWC when I got the computer. Other people with sporadic shutdown problems seem to be pointing to bad memory as the culprit. I don't know if that applies here though, because the problem only happens on battery power. Also, I installed the memory as soon as I got the computer and it's been working fine for almost a month now. My shutdowns didn't start until a couple of days ago. I think i will remove this extra stick of memory and see if the problem goes away, just in case. Maybe you should try removing the additional memory you got from the apple store to see if you got a defective piece.
I haven't tried calling apple yet regarding this. Have you? I'm curious to see what they say about it.

Computer shuts down when not plugged in

When my computer is not plugged in it will not stay on. I've tried removing the battery and putting it back in and restarting the computer many times. Any help would be very much appreciated as to what I should do.

Try resetting the SMC first http://docs.info.apple.com/article.html?artnum=303319
Then check your battery version System/library/systemconfiguration and check is 1.2 if it is 1.3 drag it to trash and reboot then run software update to install 1.2
Check firmware update in applications/utilities
Finally calibrate the battery http://docs.info.apple.com/article.html?path=Mac/10.5/en/9036.html
If none of those help welcome to the club of the sudden shutdown...

The problem is your friend's music does not belong to you. It is owned by your friend.
I'm afraid you cannot do what you are trying to do. Restoring the iPhone is what you would have to do.
In the future, put your music on the computer and transfer it to the iPhone, not the other way.

Iphone 4s shuts down when it battery life gets to about 17%. prior to IOS 7 it would shut down at about 1%. What's up? (Oh, when I plug in recharge, the battery indicates it's at 17% or so. So, I'm not referring to battery drain).

My iPhone 4s shuts down when battery indicater reaches about 17%. When I recharge, indicater shows about 17%, so apparently this isn't fast battery drain. Oh, this happens since IOS7.

See if your phone is one that Apple has noted as requiring a replacement battery: https://www.apple.com/support/iphone5-battery/

should I bring it to apple ?

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these steps in order until the issue is resolved.
Replacing or even suggesting replacing hardware without doing basic troubleshooting first is not very smart.
If basic troubleshooting does not resolve, take it to Apple for evaluation. There is no obligation to pay for anything, the evaluation is free.

HT201401 IPhone often shuts down when it's comes about a 15 - 20 percent

IPhone often shuts down when it's comes about a 15 - 20 percent,
And when trying to turn it on appears on the screen there is a need to plug in (to charge).
After connecting to charger (after 5 seconds or so) the device turns on as if nothing had happened, and continues to work regular

That might occur if you're using the iPhone in low temperatures as the battery decharges quickly in lower temps. If you're using the phone at a normal room temperature I have no idea why your phone shuts off at as high as 20%. Also, if you use your phone in too high temperature areas the battery lifespan will decrease. The more you
Anyway, at least one time a month you should run the iphone down to 0% (or as low as you can go) and then completly charge it. Don't do any 5 minute charges, just go from what ever percent you're at and run it down to zero then recharge to full.

Imac shuts down when not in use

I purchased my 21.5" imac July 9, 2011 with Snow Leopard. No problems for 1 month. Then about August 12th or so, my imac started to mysteriously "shut down" when not in use. I'll be working on it, then get up to go pour myself a cup of coffee or something...then I come back to my computer that has now shut off. It is NOT asleep...it is OFF. So I turn it back on and it is fine. This has happened a few times now within a week. Anyone else have this problem?
By the way, I am now running Lyon, as of August 18th. When the imac shut down, I was usually viewing photos or on the web.
thanks!

First thing I would try is to reset the SMC, it can help with power related problems. Shut down the Mac and unplug everything including the power. Press and hold down the power button for 10 seconds. Plug in the computer but be careful not to press the power button as you are plugging it in. Wait a few seconds and turn it on. Hopefully it won't happen again. There is always Apple Support. Don't let the problem persist until your free phone tech support has expired (3 months). I would also recommend using the iMac with an UPS, and at the very least, a high quality surge protector.
If you have MS Word or a similar word processor you could try enabling the autosave feature and set it to 1 minute intervals. Keep a document open and if you come back to the computer and it has shut down, you can look at the last time the document was updated and know what time the comptuer turned itself off. It could be useful in diagnosing the problem.

ITunes shuts down when I plug in my iPod

I've used my iPod without a problem since Christmas. For the past week, when I plug in my iPod, iTunes shuts down due to an unnamed error.
I have reinstalled all my USB drivers, removed all of my Apple software twice and reinstalled it twice (once with the guidance of an Apple tech via phone). The Apple tech guy sent me to the Apple store to replace my iPod, which I did. But none of that has fixed the problem.
So now, I'm left with an empty iPod that can't sync with my library because iTunes keeps shutting down when I plug in the iPod. The people at the Apple store said they couldn't help me further because I have a PC. The people at Microsoft won't take any responsibility because iTunes is an Apple product. So, I'm left with a $200 iPod that is suddenly for some unexplained reason, shutting down iTunes. So now, both the iPod and iTunes are worthless.
Does anybody know how to fix this problem? I'm a singer and depend upon my iPod for rehearsal, so I need it fixed ASAP. Any help would be much appreciated.

Sorry I wasn't very clear the first time. Changing the Drive Letter is done through Disk Management in Windows. I suggested you open the itunes preferences in hopes that you would then be able to connect your ipod without it crashing.
To change the drive letter:
Since we know this trick works
First open itunes, then select Edit-Preferences and leave this open.
Then, follow the steps [here|http://support.apple.com/kb/TS1493]
I use Q, R and T for my ipods so the computer doesn't confuse it with other removable devices.

Why does my iphone 3gs shut down when battery gets to 80%? have installed new battery and nothing changes?

Why does my iphone 3gs shut down when battery shows 80%. a couple of months ago is shut down at 60% but has continually gotten worse. this was before 5.0. i took it to a repair man and he tried a used battery, a new battery, and the original battery. nothing helped. 5.01 didnt help either. What is my problem?

Fully discharge the battery (till it shuts down and won't turn on) and then fully recharge it (100%). This will recalibrate the battery meter. You may need to do this a few times.

MacBook shuts down when not connected to power supply

Hey everyone, I'm making this topic for an issue that has gotten me edgy lately.
My MacBook (not new) has a habit on shutting down on me instantly for some reason when the MacBook is not plugged into charge. Here is the strange thing though, if I unplug the charger plug and set it still on my desk, I have more of a chance of the laptop not failing on me, but when I carry the MacBook around, it has a 90% (guestimate) chance of shutting down on me.
Even after having the laptop plugged in for 12 hours, the laptop just goes into suspend mode.
I have to wait a couple of seconds before I can turn it back on (by pressing the power button, not any key).
Also, when I shut down more programs at certain times when not plugged in, and having the screen brightness low, the Mac does not shut down so fast.
Any advice?!
Thanks

Could be you battery. Mine shuts down when showing 40% charge left and I have to plug it into the power supply to fix it. I found out it was the battery by downloading coconut battery. It's an application that allows you to check the status of your battery (Link at bottom). I suggest you get that and when your macbook shuts down again, plug it into the mains, start it up and run coconut battery. If it shows your nearly out of battery power then that's your problem.
I was showing 40% left when it shut down. Did the above and I had no power left. It happens when the battery is old about 250-400 loadcycles
Hope this helps.

IPhone 3GS Shuts Down when receiving a call

My wife's iPhone 3GS has an odd problem - sometimes - but not always - when an incoming call comes in the phone shuts down. The phone doesn't ring (or vibrate) it immediately shuts down to the power off state - and it's only after a while that I realise the phone is off - later I find out someone tried to call.
Has anyone else seen this problem?
It's a 32GB 3GS on the latest firmware 3.1.2 (7D11) and 05.11.07.

I'm having exactly the same issue with my iphone, and same specs. It's a new work phone so discussed with IT manager. She advised returning it so it could be sent back for repair. Would be interested if you have heard of any other fixes as not keen to be without the phone, although that needs to weighed against the fact it randomly shuts down when a call comes in!
