Iphone 5 random shutdown when battery is not low?

Recently My iphone5 keeps shutting down itself randomly when it still has enough battery. It could happen when battery is 50%, or 60%. The lower battery, more frequently does shutting down happen. It is the latest ios7 version. And I tried to enter DFU mode and restored my iphone. But the problem is still unsolved. I want to know if it is a hardware problem, or something wrong with iOS system. And what further steps I should take. I don't think restoring it again in DFU mode would help.

There are other conditions that cause the iPhone to shut down - not only a low battery.
Examples:
Operating the iPhone in a temperature that is too hot.
Operating the iPhone in a temperature that is too cold.
Storing the iPhone in a temperature that is too hot.
Storing the iPhone in a temperature that is too cold.

Last Friday, the broken glass of my iphon g3 replaced. Since then, remains the screen of my iphon regular black. The battery is not empty. By the restart I get my iphon back to life. It always comes back sooner. The last 24 hours 3x. Is there a solution?

Since Apple doesn't repair iPhones (they replace them) you will have to take it back to whoever "fixed" it. Since it's been opened by an unauthorized 3rd party, it is no longer eligible for replacement by Apple.

Iphone 4 auto shut off when battery 20% and lower.

My Iphone 4 auto shut off when battery 20% and lower. The phone is only 1.5 years old. Can I know why this happen?

Most commom reason for this is faulty battery. You could try Restore with iTunes on computer, at end when prompted, Set Up iPhone as New. If still problem and you have AppleCare, take to Apple for resolution. If no coverage, make Genius reservation and take to Apple Store for quick free battery diagnostic testing.

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.

Random Shutdowns when on Battery Power

Hello!
My Macbook Pro is about 2 years old and it seems to be randomly shutting down when the battery is at about 40%. This has happened twice in the past 3 days. Both times, when the battery was at about 35-45% and was not plugged in with an adapter the computer would shut down without any warning and wouldn't turn on again unless it was plugged in. Once it restated (the full boot up) no applications acted as if they had "crashed" (though, thankfully I was never in the process of working on something, just browsing the internet), and Firefox, when reopened, opened up all my tabs as before the system crashed. Also, once it restarted the battery wasn't depleted and still showed about a 45% charge.
To complicate matters, the computer doesn't die every time the battery reaches 35-45% (one of those days it decharged fully and gave me the reserve battery warning as usual), so it doesn't seem to be a dead cell in the battery, if I understand correctly. The first time it randomly shut down was 3 days ago. Earlier today my computer decharged fully and gave me a reserve battery warning, at which point I plugged it in. However this evening it again died on my at 45% battery life, I restarted it by plugging it in, and then as an experiment unplugged it once it had started up. In the next 10 minutes it shut down once more.
I've removed the battery and there isn't any dust or grime, so that's not the problem as far as I know.
My battery information in the System Profiler comes out like this:
Charge Information:
Charge remaining (mAh): 1731
Fully charged: No
Charging: Yes
Full charge capacity (mAh): 2547
Health Information:
Cycle count: 125
Condition: Check Battery
So, is my battery dead or in the process of dying and I should consider replacing it? I'm still a little fuzzy on how cycle counts work, but 2 years seems like not a lot of time before replacing a battery.
Maybe my computer is overheating (I do have a case on it, but it should ventilate correctly)?
Or perhaps it has a virus? Though I have Norton Antivirus and it runs scans about 3 times a week and has not found anything ever.
I'd like to get this sorted out so I don't have to be paranoid about loosing my data in case I ever am working on something. And I'd really like to not have to plug it in all the time (I'm a college student...plugging it in everywhere on campus can be a pain in the ***).
Thanks!!

mybluehighways,
looking at your battery figures, your description of the computer's behaviour, and the age of the battery it is pretty clear that it has simply deteriorated to the point where it can no longer sustain normal operation.
The short answer is that you need a new battery.
The long answer is that when computers running on batteries shut down unexpectedly it is simply because the battery is not able to provide the transient power needed for a particular task or tasks. It usually occurs because the internal resistance in the battery has built up to the point where, though the battery can still store electricity, it can't deliver it sufficiently quickly to meet the demand.
It is like a car with plenty of petrol in the tank but a faulty fuel pump. It will trundle along quite happily on the flat for quite a while, but if you put your foot down to overtake or climb a hill the engine will stall because it can't get enough gas to meet the increased demand. At this point you can choose the dangerous option to keep on driving on flat roads only, and to never overtake anything or "put your foot down" to get out of trouble until the fuel pump dies completely (which you can be certain it will soon do), or you can get it fixed by getting a new one. The same applies with batteries, though you are "only" risking data loss and hard drive corruption with a computer, rather than your life!
The variation in the amount of time for which it ran before cutting out will simply be due to variations in power demand when doing different sorts of tasks. You will find, too, that the battery will cut out earlier and earlier, under lower and lower power demand situations, as it continues to deteriorate. (Once these batteries start exhibiting this behaviour you can be sure that they are well on the way out)
If you take your battery to an Apple AASP or Apple Store they can quickly test it for you, but if I were you I'd be preparing to buy a new one.
This has nothing to do with viruses or the like. It is a very common experience with the batteries in these MBPs when they are around a couple of years old. My own first battery in essentially the same model became problematic after 18 months.

My iPhone 5 randomly shutdown and rebooting doesn't seem to work for me, what should I do?

It also happens when I'm charging my phone, and also the battery percentage doesn't show that correct battery level not unless I turn off and on.. I tried rebooting the phone but it doesn't seem to work for me, random shutdown still happens..

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 LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 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 when battery life still shows 10% left

Install iOS7 on iphone 5 and the device will power down sometimes when it still shows 10-20% battery life then not power back on, while displaying that it should be plugged in. Also the phone will sometimes jump from 20% life down to something like 1-3% on the indicator in mere seconds and powers off shortly thereafter.
Basically the phone gets down to what shows as 20% battery life and may shut down at any point after that....

This could be because the battery has not been properly calaberated try the link below. http://www.apple.com/nz/batteries/iphone.html

Iphone 5 switches off when battery still has 15%

After updated to iOS 7, my iphone 5 always switched off when battery still have 15%. Anybody have the same issues?

Sounds as if the battery may need to be recalibrated. Let the battery drain until it turns off. Then connect the phone to the charger and let it charge to 100%. Disconnect and then use it. It should get it back to a better read. The batteries are designed to shut down when the battery has a certain amount of power left. The battery percentage is not always that accurate.
You can take a look at this link from Apple about batteries. http://www.apple.com/batteries/iphone.html

Random shutdown issues, battery, and overheating.

Hi,
About two weeks ago, I've experienced random shutdowns on my MacBook Pro (Bought it on October).
I am not sure if all this problem was about battery issues. First I've charged it for the first time and only lasted 1 hour. then I recalibrated it and now it last 2 hours and a bit more.
Now, apart from having battery issue, I've experienced random shutdowns from my laptop. I had installed all the available updates for my laptop.
Reading all the posted topics about heat, shutdowns and batteries, maybe my problem is just overheating.
So I've installed the fan control, adjusted the speed to 3500 rpm and worked fine.
But one thing came to my mind:
Is it safe for the fans to actually force the speed all time? if so, their cycle life could be shorter?.
On either case, what if the MBP actually has a defective factory error and if I still be using it, it could completely "melt from the inside"?
Does the battery itself has something to do with the overheating itself?
Maybe I should call for a laptop replacement as well.
Any suggestions?

Your Mac will very likely last as long as you own it or otherwise choose to upgrade. The heat issues posted here are not entirely valid. With that said, you might want to verify that your battery isn’t on the recall list by viewing the link provided below.
Excerpt:
"The affected batteries have model number A1175 and a 12-digit serial number that ends with U7SA, U7SB or U7SC. To view the model and serial numbers located on the bottom of the battery, you must remove the battery from the computer. The battery serial number is located above the barcode. See photos below. Only batteries within the noted serial number ranges need to be exchanged."

ITunes detects iPhone over WiFi only when it's NOT connected to a power outlet

iTunes detects my iPhone over WiFi only if it's NOT connected to a power outlet, so if I try to sync it fails.

Hi there argelle1!
I believe you will want to restore this iPod in order to resolve this issue, but there are some other troubleshooting steps you can try before that as well. Those steps can be found in this website:
iPod nano (6th generation): Hardware troubleshooting
http://support.apple.com/kb/ts3474
Specifically, this is the section that refers to your issue:
Will not turn on or screen remains dark
Connect iPod to power for at least ten minutes to ensure that the battery has enough charge to allow iPod to turn on.
If iPod does not turn on after ten minutes, try resetting the device while it is still connected to power. Reset the iPod by holding down the Sleep/Wake button and the Volume Down button for at least eight seconds or until you see the Apple logo appear.
If the Apple logo appears on the display, connect iPod to a computer and verify that it appears in iTunes and can play music. If iPod appears in iTunes and can play music, no further troubleshooting is needed.
If the screen remains dark and will not turn on, then your iPod may need service.
Thanks for coming to the Apple Support Communities!

Braden

My iphone starts playing music when I'm not even touching the phone

My iphone 4 starts playing music when the phone is in my purse and I'm not touching it or even going through my purse. I've tried making sure the ipod is not set to a song but rather to a menu screen when I close it. Sometimes I haven't even used the ipod recently. My phone also calls people when I'm not touching it. Does anyone else have this problem? It must be something I'm doing but I can't figure out what it could be. I'd appreciate any help!

Mine plays music when I have the iPhone 4 in my pocket and bend over a little, I know that kinda 'scrunches' the phone slightly but no other iPhone I've had ever did this and I've treated them all the same. I'll be walking along, pick up something and then the music starts playing. I don't touch anything, never attach headphones, basically the phone is asleep but somehow something triggers the music to start playing. I've entered this as a separate thread but no one seems to know why this happens. I suppose I could take the phone back and exchange it for a new one, but it would be better to know what is causing this.

Macbook shutdown when battery in place.

My macbook pro work great when connected to the power supply and no battery inserted. When battery is inserted and power supply connected it shuts down within minutes of restart. Help.

It might be helpful if you indicated the EXACT model/year MBP that you have.
Perform a SMC reset:
http://support.apple.com/en-us/HT201295
Open System Profiler>Power and post this from your MBP:
(make certain that the charger is connected)
Try to run an Apple hardware Test:
https://support.apple.com/en-us/HT201257
You can use the original installation disk that has the instructions on it. Note that an error free AHT is not drfinitive.
I suspect that there may be something wrong with your battery.
Ciao.

Getting a warning when battery power gets low.

Hello!
I would like to get a warning, like a window popping up, saying that my battery power is running low. How can this be done?
Is it possible to make my machine hibernate if I don't connect it to power if I don't react to the warning?
I'm using a Lenovo Thinkpad T400, with an updated Arch installation, running Fluxbox.

I use this script to alert me when battery is low
#!/bin/bash
#low battery in %
LOW_BATTERY="10"
#critical battery in % (execute action)
CRITICAL_BATTERY="5"
#sleep time 4 script
SLEEP="60"
#acpi battery name
BAT="BAT0"
#action
ACTION="/sbin/poweroff"
#display icon
ICON="/usr/share/icons/oxygen/48x48/devices/battery.png"
#notify sound
PLAY="aplay /usr/local/bin/bears01.wav"
MAX_BATTERY=$(cat /proc/acpi/battery/BAT0/info | grep 'last full' | awk '{print$4}')
LOW_BATTERY=$(($LOW_BATTERY*$MAX_BATTERY/100))
CRITICAL_BATTERY=$(($CRITICAL_BATTERY*$MAX_BATTERY/100))
while [ true ]; do
if [ -e "/proc/acpi/battery/$BAT/state" ]; then
PRESENT=$(grep "present:" /proc/acpi/battery/$BAT/state | awk '{print $2}')
if [ "$PRESENT" = "yes" ]; then
STATE=$(grep "charging state" /proc/acpi/battery/$BAT/state | awk '{print $3}')
CAPACITY=$(grep "remaining capacity" /proc/acpi/battery/$BAT/state | awk '{print $3}')
if [ "$CAPACITY" -lt "$LOW_BATTERY" ] && [ "$STATE" = "discharging" ]; then
$($PLAY)
DISPLAY=:0.0 notify-send -u critical -t 5000 -i "$ICON" "Battery IS low. Plug or Pray." "remaining $CAPACITY mah, shutdown @ $CRITICAL_BATTERY mah"
fi
if [ "$CAPACITY" -lt "$CRITICAL_BATTERY" ] && [ "$STATE" = "discharging" ]; then
$($ACTION)

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 !!!
