This has happens about twice or three times a day. The last time when I took a photo it shut down even though I had 49% battery. When I tried to restart it I got the connect to a power source icon. Then if I wait a few mins I can restart ok and it then shows the battery level as it was before. Has anyone else had this problem? or know what is wrong and how to solve it. Thanks
Hey RichardNWhite,
Thanks for the question, and detailed information. To completely isolate the issue, you may want to follow these steps:
Will not turn on, will not turn on unless connected to power, or unexpected power off
- Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
- Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion.
Learn about LCIs and corrosion.
- Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
- After at least 15 minutes, if:
- The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
- The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
- Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
- If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
- If the display turns on, go to step 4.
- If the display remains black, go to next step.
- Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to
restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
- If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

IPhone 5 shuts down even when it's on the charger
My iPhone 5 keeps shutting down even when it has full battery. It doesn't last more than 2 minutes on and that's when I am able to turn it on. When I connect it to the charger sometimes it just flashes the apple continuously. I noticed that when it's on sometimes it doesn't connect to the Wi-Fi and I have no signal it just says searching. It just started doing all this 3 days ago, befire that it worked perfectly fine. Does anyone know what could be wrong with it?
Probably a bad battery. See if it qualifies for replacement: iPhone 5 Battery Replacement Program - Apple Support

The on-device battery meter is 'off sync' with the actual battery charge. There are a couple of ways you can try to repair this...
Leave the device to charge an hours or so, and then, still connected to the charging cable, remove the the battery from the device a few seconds and reinsert it. Watch over the next couple of days to see if the charge and the battery use is in sync.
Roughly every 30 charges, deliberately discharge your battery to 10-15%, and fully charge to 100% afterwards. This will help maintain the accuracy of the “fuel gauge” on the device (your battery meter or scale).
Don’t drain your battery every day to 10-20% of its charge. You can actually expect battery problems by draining the battery. Again, to repeat, top-off your charge during the day whenever convenient – even ten minutes in the car or at your desk will give you an extra 20-25% charge.

iMac keep shutting down black screen then have to hold power button down then turn it on again i did this 4 times in all of a period of 15 minutes what to do ??
Hmm. The problem still may be the RAM - Apple buys the RAM it puts in its machines from third-party vendors (usually Hynix) so it could be a RAM problem.
There are a couple of things that you can do yourself before taking your machine into an Apple Store or an AASP... download and run an application named Rember that will run a RAM test for you - let it run for a couple of hours or even overnight. If it turns out that your RAM is faulty, Rember will let you know. If it is faulty, then you have a couple of options - replace the RAM yourself or (particularly if you're under warranty still) take the machine to an Apple Store or AASP and have them replace the RAM.
If Rember finds no fault with the RAM, then you'll need to take it into an Apple Store/AASP and get a free diagnosis on the machine. Three beeps do usually indicate faulty RAM, but if it tests good with Rember you likely have another problem - it could be something as simple as the RAM, somehow, not seated correctly or signs of another hardware problem.
Run Rember first... call back with results.
Good luck,

IPhone 5 shuts down even when battery is not empty
My iPhone shuts down evenw hen i have over 10% battery life left, it even turns off when i walk into a building after walking outside in the cold weather. It's extremelly frustratin as i can no longer rely on my phone as it can turn off any time of the day. What do i do
I have the exact same problem .. sometimes when I use my camera, with plenty of juice, it just shuts down and won't restart claiming the battery is dead ... I plug it in and instantly there is the plenty of juice it had before .. not dead at all... sometimes it happens when I am just using an app ... pretty random actually but VERY inconvenient.
I have always boasted about my iphone being reliable and not having any weird issues ( as opposed to my friends who have Windows phones or other ones) but now ... THIS !!!!??
...... I have resorted to carrying one of those back up batteries in my pocket and a charging cable in my car ...
very inconvenient but until THEY FIX the problem, I can't trust my phone
It is too frequent a problem and occuring with too many people under same conditions to consider it being a battery or phone issue ... whether Apple recognizes it as an OS situation or not .... I do !!!
FIX IT PLEASE !!! -

My Ipod Classic keeps shutting down, even when fully charged
I have upgraded my Ipod classic operating system and all was well. Suddenly, it has started shutting down after 5 minutes of use, even when the battery is fully charged.
What iPod software version? Restore the iPod again
But maybe it is just set to sleep in 5 minutes.
Check the settings and set it to OFF

Ipad2 won't shut down even when i press the sleep/wake button and the home button at the same time.
I can't shut down my ipad2 even when i press and hold the sleep/wake button and the home button at the same time.
If the screen appears to be zoomed in, then does tapping the screen with three fingers zoom you back out ? When zoom is on you should also be able to scroll around the screen using three fingers on the screen.
If you are seeing the keypad then that should be for the iPad's passcode, I assume that you have one set ? If the iPad is disabled then I wouldn't expect the keypad to show. -
Iphone reboots/shuts down even when plugged in
Here are the specs:
iPhone 4, iOS 7.0.4, 16gb, GSM
I've never had any big problems with this phone while using it, but today it randomly shut down, so I thought it might be a battery information glitch, because it has happened with a different iPhone of mine. So, I connected my phone to electricity, it turned on and stayed like that for a while (I had fully charged the phone a few hours ago) and it showed 94% of battery left, which is quite normal. The odd thing was, that it was searching for carrier and it was impossible to turn wi-fi on, the button was not responding. So I went ahead and rebooted the phone, still had the same issue. While still connected to the charger, the phone suddenly died again, showed low battery and turned on again. After a minute or two, the same thing happened again and after another reboot - again, again and again. I tried to reset the settings, still no carrier and still rebooting, even while charging. I tried completely erasing data and settings, but it was impossible to do that, because it asks for the iCloud password. Since it cannot be connected to the internet, there is no way for me to do that. When unplugging the phone, it dies in the same second. Next, I tried connecting the phone to my computer, but I can't even get it to turn on for a minute, because it reboots all the time after a few seconds (doesn't get enough power through the usb, I guess). Tried DFU mode, still no success. While connected to the computer, iTunes won't show the device connected to the computer.
So, there is no way to update the OS through the phone, because there is no way I can connect it to the web, resetting the settings won't do a thing, completely erasing the phone is impossible, because it cannot be connected to the internet, impossible to connect to a computer, because it reboots all the time, so no way to restore the phone. Basically, I can't really do anything with it.
I searched all over the internet for a solution, but couldn't find a single article about an issue like this. Is there anything that comes up in your mind, that might help? If so, please post an answer.Oh, forgot to mention. No, it's not jailbroken.

Got an iphone 4s for christmas. having problem with it shutting off even with fully charged battery. will not come back on nor can it respond to charger. next day usually comes back on then does same thing over again.
Perhaps you got a bad iPhone. Take it to an Apple store or an authorized service center.

MacBook shuts down without warning during calibration (39% battery power)
My MacBook has been shutting down without warning during recent calibrations (which I've done approximately every two months). Most recently it shut down after 2 hours and 20 minutes on battery power with a battery reading of 39% -- i.e., nowhere close to the 0% of a fully rundown battery.
The result is that:
I'm not seeing the 'low battery' warning dialog before the computer shuts down; and
(ii) I'm not able to save current work and close all applications when the battery's charge gets low, before the computer goes to sleep (because it just shuts down without warning)
Can I do anything about this? Is it just an unavoidable indication of declining battery performance?
My MacBook is 15 months old. Current 'battery information' is listed below.
Thanks. Replies appreciated.
Battery Information:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 4792
Remaining Capacity (mAh): 4790
Amperage (mA): 0

1. I'm not sure how to match the path you listed re: the '1.3 battery update' to what's on my MacBook. Maybe I just don't understand how to interpret it, but I don't have a root folder (or any other folder) identified as 'MacBook.' When I used Spotlight, I also didn't come up with a BatteryUpdater.bundle. A file named BatteryUpdate2007001.pkg was all that Spotlight turned up.
On my MacBoook my hard drive that I boot from is named Mort's MacBook. Yours may be similar I don't know. It is the drive you boot from. Mines shows in finder as the top level drive. The next level in column view. Then you find the System file and go from there.
If your not sure what you named your drive or which one it is click the apple in the upper left corner and then pick *About This Mac* You then should see *Startup Disk* and next to that the name is what you refer too when you look for the folder path I gave.
2. You recommended resetting the SMC. However, the info file you provided a link for says it shouldn't be "necessary except as a last resort in cases where a hardware failure of the power management system is suspected." Does that accurately describe the condition I reported? Also, the problems listed as possible reasons to reset the SMC don't include the one I posted about.
The reason I suggest resetting the SMC is that your changing one of the components that is controlled by the functions of the SMC. The battery is a big part of the system which the battery update changes. To get it to be sure to recognize the new bundle you reset the SMC. The instructions linked are not all inclusive but if you don't want to reset it that is up to you.
3. Similarly, re: the 1.2 Battery Update, it's not clear to me that any of the listed 'symptoms' of a faulty battery apply in my case -- unless what I reported indicates a "+low charge capacity/runtime+." Does it?
The battery update instructions are again not all inclusive. If you don't want to do it that is fine. All I know is you have a MacBook Pro update installed at the moment. You don't have a MacBook Pro. This suggestion of mine has helped many people with problems as reported by you. You do not have to do anything you don't want. That is your choice. Is your battery cutting off at 39% considered normal operating or capacity to you? I personally would call it a faulty battery, but thats just me.
What would be your definition of a faulty battery?
4. Apparently, you had a faulty battery which Apple replaced. I wasn't sure from your message whether you had other things going on that made it clear you had a faulty battery, or only the same symptoms I reported. Were there other power-related problems in your case, or only, as you wrote "the same thing as yours except mine cut off at 28%"?
I guess I misunderstood your original post, everything yours was doing mine was doing except mine cut off at 28% not 39%. I can only give advice on what you post. Are there other things happening that you didn't mention?
My idea of a faulty battery must be different than yours. If I don't get warnings I should and the battery does not work like it used to then that is a faulty battery in my opinion.
If your not comfortable with any of my suggestions contact Apple support and maybe they can help you. Possibly one of the other posters on here can give you different advice that you agree with. Never do anything advised in the forums unless you agree with it. -
