MBP shuts down with over 30% charge

Recently my mbp has just been shutting down without warning, even with a battery at over 30%. I try and reboot and it turns on, then shuts down right away. Once I plug it back into to a power supply its fine. I've had it for about two years, been through 223 cycles, and it says its in good condition.

When did you last properly calibrate your battery?
http://support.apple.com/kb/HT1490
Calibration should be done approximately every two months. Failure to do so for a long period of time can result in the microchip "fuel gauge" in the battery losing the ability to accurately determine the remaining charge, and it will report that there is more charge in the battery than is actually present. As a result, the computer will not initiate Safe Sleep at the proper time, and instead undergo a hard shut down, one of the main causes of hard drive directory damage. Once the battery is in the state resulting from a failure to calibrate, it is not possible to calibrate the battery, and it will need to be replaced. Note that Apple specifies, +"A properly maintained Apple notebook battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles."+ Calibration is considered part of proper maintenance

IPhone 5 shuts down with over 30% battery remaining

My iphone 5 is shutting down with over 30% battery remaining. It used not to shut down with still around 2% remaining but its increasing with every day now. For the last 5 days or so it is shutting down when showing even 30% remaining. When plugged in again, the battery is all drained down. Please someone give some valuable advice.
thanks

Sounds like a definite hardware problem. You should still be in warranty, so head over to an Apple Genius Bar and they will either repair or replace it. A replacement will be much more likely, and it's free (if in warranty).
Good luck!

My iPhone 5 shuts down with a 10% charge remaining, is there a fix?

After my recent software upgrade my iPhone 5 shuts down with 10% charge remaining. This has never happened before. Is there a fix?

The battery gauge probably needs to be recalibrated. It "thinks" there is more charge in the battery than the battery thinks there is.
When it shuts off charge for just a minute or two, then restart (hold HOME and SLEEP until an Apple logo appears). Deliberately run the battery down until the phone shuts off at 1%. If it shuts off above 1% repeat the above until you get to 1%. Then charge for 4 hours with the wall adapter without using the phone. This process will recalibrate the battery gauge.
To prevent this from happening again about once a month run the battery all the way down to 1%, then continue until the phone shuts off. Apple recommends this in their battery help article, but they don't say why you should do it. The have some hokum about "keeping the electrons moving." Honestly! The iPad battery tip gives the correct reason.

IPhone 5 shuts down with the battery at 40%

I'm having issues with my iPhone 5. It regularly shuts down with the battery being far from 0%. When I took it to the apple store, a "genius" said that the battery is fine and restored the phone to the factory settings. I set it up as new without touching the backup (with iOS 8), but the iPhone keeps shutting down with a half charged battery. If anythings, the problem only became worse with iOS 8.1. I would appreciate any suggestions on how to fix it.
The iPhone is out of the warranty and is not eligible for battery replacement. Another issue I have is that the home button often responds with a delay, but I don't know if it's related to the main problem.
Thanks

MBP shutting down unexpectedly even though battery meter still has charge

Hi,
just in this last week, my MBP has been shutting itself down very suddenly when on battery power when there's still charge left.
At first there was about 25% charge left. Over the next few days, that went up progressively till today it is now shutting itself down with more than 50% charge left.
Has anyone had issues such as this? and what should i do to rectify it?
I'm going to try recalibrating the battery.
I don't usually use the MBP with the power connected
I try where I can to charge and then disconnect and use till power is low.

I was having same problem: meter shows plenty of charge left, yet MBP shuts down. When I decided to take a look at my battery (also with recall in mind) was horrified to find it swollen and warped so badly -- pushing out of its casing. Could barely get it out and then back in. That I'm getting any charge at all amazes me considering how badly the battery is misshapen.
Has anyone else had this problem? I'm beginning to think Apple's not being quite up-front about the seriousness of the problem: Yes, MBP gets hot, yet no more than my old PowerBook and iBooks.
But, had we been given batteries which are perhaps really unsafe, not to mention causing lost work time and maybe systemic difficulties?

MBP 17inch A1151 shuts down with battery

I just bought a used MBP. It came without a batter. It booted fine when I bought it and ran off of my MacBook power adapter (60w). I ordered a new battery and 85w charger. Whenever I put the battery in with it started up, the MBP shuts down within 5 seconds. If I put the battery in when it is off and boot it up, it will not get through the boot process without shutting down. I left the battery in with the MBP off and plugged in to charge the battery. It is fully charged.
I have seen reports of this problem and wonder if it needs a new logic board or could it be something else.
Or, if I should just use it without the battery as a desktop computer.

I saw that some people were posting battery reports, so I checked mine. I booted it without the battery and opened the Power information to see the battery cycle count, etc. So, i installed the battery and the battery indicator in the menu changed from X battery to plugged battery, said it is at 96% and charged, but the system info never changed from no battery installed. I even went to printers and then back to power and it never noted a battery was installed. weird.

my iphone 4s shutting down with 20% charge

Hello klmcholden,
The following article provides some useful troubleshooting steps that can help restore proper function to your iPhone.
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.
My issue is still not resolved. What do I do next?

Computer shuts down with charge on battery and no warning

without warning and plenty of charge on my battery my mac book pro shuts down? if it just sits there in sleep unplugged it seems to run fine, but if its unplugged and i try to use it (with a charged battery) it shuts down with out warning. started about 3 months ago. Is the battery just old..?

It is almost certainly a sign that your battery is dying, timskins.
The problem is that when batteries deteriorate their internal resistance increases and they are no longer able to deliver power when it is demanded, even though they still have the ability to store it. They may chug along providing low power for quite a bit longer, but when your computer suddenly needs a bit more (because of increased CPU or GPU demand, or the HD spinning up or whatever) it is unable to provide it and the computer shuts down unexpectedly.
Think of it like driving a car with a bad fuel pump. Your car is driving along a highway with a full tank of gas. Its running smoothly enough. You put your foot down to accelerate up a hill or overtake a another vehicle and the engine dies because the fuel pump can't meet the greater demand for gas. The tank is still pretty full but the fuel can't be pumped in fast enough to keep it running in a high demand situation, so it shuts down.
See the section dealing with increasing internal resistance in batteries at http://www.batteryuniversity.com/parttwo-31.htm for more about such things, or http://www.buchmann.ca/Chap9-page1.asp for a longer, more technical, account.
Once this starts happening the only options are to get a new battery or to avoid any work that makes much demand on power (like visiting a "Flash" based website or, when it gets bad enough, even spinning up the HD from a stationary situation.) Unfortunately even with light use the battery will soon reach a point where the regular peaks of CPU and HD use will become too much for it and you will suffer more and more unexpected shutdowns until the battery is replaced.
My suggestion would be that you take the battery to an AASP or Apple Store, where they can quickly "stress test" the battery for you to make certain that in your case this is, indeed, the problem.

Snow Leopard shutting down with no warning is getting more complex!

I have a series 1 Macbook Pro and have updated to Snow Leopard. As with most other people I immediately got problems with the "battery Service" message. So, having read all the various posts, and tried re-calibration, I bought a new battery.
Charged fully and disconnected adaptor. The machine shut down with no warning at about 85%! I tried a few more times after fully charging the battery and it shut down a number of times - 83%, 85%, 89% and 98%. The battery shows a cycle count of 1. The last time it shut down (89%) I decided to try re-starting without plugging the adaptor back in. The machine started and ran up to the point where it properly started Snow Leopard - when it was about to change from the blue screen - at which point it shut down again. I tried this a number of times and it was absolutely conisistant, doing it every time.
I then had the bright idea of plugging in the adaptor but watching the LED to see what happened. The LED came on green for 1 or 2 seconds, then went red. I then immediately unplugged it again. I then tried to start the machine with battery only. It started perfectly and went on running until down to 15% at which point it shut down, again with no warning. Tried re-starting - it wouldn't! Plugged the adaptor in so that it would charge the battery whilst using the machine. Then, much to my amazement, while the adaptor was still plugged in, and the battery was far from fully charged, the machine shut down - again without warning. That's "it shut down with battery installed AND mains connected". The machine then wouldn't start, with mains connected. It would switch on for a few seconds then shut down again. To get it to start I needed to remove the battery and run it on mains only.
That's where I am at the moment, running 'mains only' with no battery installed. It looks as if Snow Leopard sets the battery monitor / charging hardware incorrectly on the MBP. Once set incorrectly it looks as if it loses itself!
Has anyone else experienced anything like this?

It really doesn't get any better! Well, not a lot. I decided that I'd try yet another brand new battery. I charged it fully, disconnected the mag connector and it ran happily without shutting down - hooray. However, after putting out the message about low power and about to shut down, at about 5%, it ran to about 2% and shut down without warning. It didn't go to sleep.
I then couldn't get the machine to start again. I reset the SMC and still no joy. it would start to run, flash the screen a couple of times and then die. To get it to run I had to disconnect the battery, start it, then plug the battery back in again. Snow Leopard does appear to do something odd with the charging hardware. It appears to leave it in an odd state.
You may be right about Battery Update 1.3, but there appears to be no way of installing it under 10.6.8 - unless you know something I don't!

Macbook Pro shuts down with 40% battery left... does not just go to sleep

Hi,
Our MacBook Pro has started to shut down with about 40% battery left. After it has shut down, I press the button underneath the computer and 2 our of 5 lights light up on the battery. I wouldn't mind if it just went to sleep but I totally have to restart it and lose everything I have been working on when it died. The computer used to go to sleep when the battery got to 0%, then I could plug it in and keep working.
I don't know if it's a software issue or a battery issue or a firmware issue.
Any tips would be MUCH appreciated.
Thanks a lot.

I have read so many articles across the internet with people experiencing this problem. This is the conclusion I came to.
I could not calibrate my battery as my system would hard power down before it got anywhere close to draining the battery entirely. The last 10 cycles on my battery were attempts at calibrating. The most common cause would be because the battery in our macbook pro does contain something close to the charge being reported by the computer, but cannot deliver it. Your fuel gauge is probably not incorrect, especially when the leds on the battery itself show a charge that should be capable of running the machine. Even if it is not calibrated correctly. The internal resistance of the battery itself has compromised the batteries ability to deliver the amperage necessary to run our machines. After finally realizing this, I turned my screen brightness all the way down, and sat all my power settings to max battery life without allowing the machine to go asleep. Then, I went to sleep myself =). In the morning it appeared as though I had a successful calibration and the machine did not power down hard. Depending on how bad of shape your battery is in, this may or may not work. Either way, it didn't matter much. Even with my fuel gauge being correct, if my screen brightness was cranked up and I was doing anything somewhat processor intensive, my battery failed to provide the needed amperage and powered down my system hard again.
The battery really does have the amount of power it says, it just cannot deliver it as fast as needed. At a slower rate, it will work. A replacement battery is needed. I cannot explain the strange jumps/dips in storage capacity but would guess these numbers are a guide, and more than one environmental factor can change this number. Also, once the internal resistance builds up inside the battery and the inability to calibrate happens, it compunds the problem.
My machine is a first gen intel macbook pro. A few months after I bought it, I had battery problems and apple replaced my battery. My machine is 31 months old, it's battery is somewhere around 27. I tried to get apple to replace my battery and they told me no. I was 40% healthy @ 207 cycles. Many people complain about this but it seems reasonable to me, I didn't argue. I do believe my battery failed prematurely, however, it was due to a few factors and I do not think it was the batteries fault. My machine was one of those nice overheating first generation macbook pros. To make the matter worse, one of my internal fans stopped working. I knew this as my istat pro program showed me 1 fan @ zero rpm. I figured I had applecare and had work to do, so continued to use the computer for several months. I did quite a bit of video encoding and processor intensive work. When I would get to work in the morning, my granite desktop was really cold, however, after a half hour or so with the macbook pro running the heat would dissipate through it and warm it up nice and comfortable! lol, some may not think this is funny, but it worked well for me. I frequently had over 180 degree cpu temps and the bar above the keyboard being too hot to lay your hand on and keep it there. I am sure some of this excess heat contributed to the premature failure of my battery. The type of batteries in our machines are killed by heat, charge amount, cycles and age. Probably in that order for most users. So, can I blame apple because my unit ran hotter than it should have because their fan failed! eh, maybe, but I am happy with this laptop overall. I have never had a single laptop for more than 15 months and have had this one for over 30 now.
I ran across this site somewhere, it may have been another user on these forums, I cannot remember. http://www.batteryuniversity.com/partone-19.htm On this page, it talks about our batteries, the effects of heat and level of charge in combination with age. At 77 degrees F., charged to 100% (which is very typical of our machines, or close to it) after one year the battery is 80% as good as it was when it was new. At 32 degrees it is as 94% as good as new after one year. Jump up to 104 F. and the battery is only 65% as good as new after 1 year. Sometimes my computer is running for days and sometimes the environment is warm. Add that to the heat produced by the machine itself and I bet the battery sustained 100 degree temperatures for long periods of time. Just for fun, at 140 degrees and 100% charge in our lithium ion batteries, after only 3 months the capacity is only 60% of its new capacity.
Anyways, that is my battery story. Sum up. The inability to calibrate is due to the batteries increased internal resistance and inability to deliver the charge at a rate needed by your computer even though it appears healthy, or somewhat healthy. You may be able to calibrate by making your laptop drain less power, turn screen brightness all the way down, turn airport & bluetooth off, let hard disk sleep, and let it go. But that will not stop the hard shut down problem, although the fuel gauge will be more accurate. Think of it like this. a 100 gallon fuel tank on a car full of gas. The fuel gauge is correct, it is full. However, the fuel line connecting the fuel tank to the engine is made of a space age material that shrinks as it ages and is exposed to heat. Eventually the fuel line shrinks to the size of a coffee stirrer or small straw. When the motor is turned off the fuel seeps into the small straw. Start the motor, it begins to sip the fuel from the straw. Rev it up (encode video), the motor demands more gas but cannot get it. The motor stalls out (your computer shuts off). Same idea somewhat. Sorry so long

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.

MBP shuts down when battery at appox. 30%

Hello,
I have a 17" MBP 2.33GHz Intel Core 2 Duo.
Recently (in the last 3-4 days) it has decided to shut down completely when the battery charge falls to around 30%. Prior to these symptoms appearing, it behaved normally with the 'low battery warning' appearing at about 5% and then going to sleep mode as opposed to shutting down.
I have reset the SMU by removing the adapter, battery and pressing the power button for 5 secs. Unfortunately the symptoms remain. Obviously I cannot re-calibrate the battery as it won't carry on below 30% charge without the MBP shutting down.
I'll be taking a trip to my local Apple dealer in the next few days but was wondering if anyone else here has any further suggestions I could try.
Many thanks in advance.

Umm... of course Apple will do something. I do not understand why you felt you had to add that to your reply. Allow me to explain:
1. I have AppleCare, therefore if it's a hardware issue then any repair will be carried out without any cost to me.
2. Apple have introduced a 'battery exchange and extension' program:
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
If the battery is at fault, regardless of whether I have AppleCare or not, the battery will be replaced as it falls within the terms of the extension program.
I have just now reset the PRAM and am running on battery power. I'll know in the next couple of hours whether that has had any effect or not.
Meantime, if anyone else has any additional suggestions as opposed to 'me too' type replies I would be very grateful.
Many thanks.

MBP shuts down and requires a reboot (not a wake up)

I have a MBP that is running 10.5.8. When the power gets low and the MBP shuts down, I have to reboot it (push the power button). This is not the case with our iBook, or MacBook (I should double check it), here we just plug it in, hit the space bar and it starts up where it left off (just like it was asleep).
Is there some setting or ?
Thanks

If there is Warranty or AppleCare make Genius reservation or set up Service and take or send to Apple for resolution. If no coverage, you can use virtual Lock Button. Tap Settings App > General > Assessibility > Assistive Touch > ON > tap new white screen button > Device > Lock Screen. This can even be used to turn OFF iPhone, by holding down on it. To turn iPhone ON, connect to power, charger or USB of computer.

MBP shuts down on AC power

sorry for the long post.
Got my mbp back from apple with new logic board and battery after repeated kernel panics. 2nd day in after running new battery down to about 20%, plugged into AC and poof, mbp shuts down. Will not boot up while plugged in. Installed secong battery and boots up fine. BUT, after this battery goes down past 30% and upon plugging into AC mbp shuts down again.
Pulling battery and running on AC alone works fine, but cannot work while charging. Must keep it off and charge until green light on magsafe.

Took in to apple store. They replaced the logic board [again] and the whole power connector assembly for the ac adapter. Also the left fan and the temperature control gauge(?)
Well that's it folks! We're back up and running now!
