I book shutting off at 50% battery
help! my ibook is shutting off at 50% battery. When it did it this morning I pushed the battery button and 2 dots lit up so I don't know what is going on. I don't get the reserve battery warning or anything, just blip, shuts down. Then when i turn it on it tells me my computer has a date set in the past or something. Is there anything I can do? Thanks.
Hi battricia,
I think that you may find that your battery has reached the end of its life. To get more info about your battery, go to the Apple menu>About this Mac>More Info and select Power. Scroll down to Battery Information and select, copy and paste the info into a new post. Given that a new battery starts at 4400 mAh (milli-amp hours) you should get some idea from the present Full Charge Capacity just how far down the road your battery is.
You might want to check Here to see if you qualify for a free replacement battery under the Battery Exchange Program.
Good luck and post back with the Battery Information.

Computer shuts off at 45% Battery
My MacBook Pro shuts off at 45% battery life, I do not get a low level warning before it shuts down. I have replaced this battery with a new one, and it does the same thing. I notice that my led on my charger blinks from amber to green all the while charging. My new battery only lasts from 45 minutes to one hour after a full charge. I have done the SCM resest and the Pram, I have done everything recommended. Still no answers. I have the original 2006 MacBook Pro and had the battery replacement exchange within the first 4 months of owning it. That battery worked fine until a couple weeks ago. I did some updates, and now it seems that it has affected my battery for some reason....This new battery I just installed last week. It's very frustrating to have to haul my ac charger with me everywhere. I do not have any extended warranty. Can anyone else give me something else to try? Below is my battery info.

For the battery to charge properly, three things have to work--the battery, the power adaptor, and the left I/O Board.
Your new battery sounds like it may be defective. Take a look at this article:
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
After 6 cycles, your Remaining Capacity in should be very close to your Full Charge Capacity of 3496 mAh, rather than 1350 mAh.
It's also possible there could be a problem with your power adaptor or the left I/O Board. Usually the way to narrow it down is to try a known good power adaptor and a known good battery. If the problem remains, the left I/O Board is likely the problem.
It may be worth taking a careful look at both the port and the end of the MagSafe connector, and check to see that none of the pins has become pushed in or something like that. It may also be that the blinking green/amber indicates a faulty connection of some sort.
Good luck! -
Macboook shutting off at odd battery percentages.
Ive had my macbook for about a year, core duo, and within the last two months it has begun shutting off when the battery is not near being low, the two times i could tell what the percentages were when it shut off were last week 15% and tonight 27%, i dont know if it has been getting progressively worse or if it is getting all mixed up percentage wise, but it has become a real problem. The computer is not plugged in when this happens and i have already reset the PMU as i was told before, this did nothing. any suggestions are helpful, thank you.
Have you done the battery update? Apple: About Battery Update 1.2.
How many cycles are on your battery? Apple: Determining Battery Cycle Count
If it is under 300 and you still have a problem after doing the update call Apple at the number listed in the update link and see about getting your battery replaced. You can also go by a store if you live near one and get help there. -

2009 MacBook Pro shuts off after low battery warning.
Today I got the warning at 10% and about a minute later, the computer just zapped off. I only had internet (Facebook and email) and iTunes open. This has happened before, more often recently, where it shuts off shortly after the warning. I've been wondering if I have a bad battery because sometimes the computer has drained all the way to 0% and then zaps off.
Is this fixable with the current battery? Or is it just old and likely needs replacement?
Any input is appreciated. Thanks!!Apple actually has a section of their website dedicated to explaining how recharge-able batteries work these days. It includes some tips on how to maximize your battery life.

IPhone 6 Shuts Off at 50% Battery
I just upgraded from the iPhone 4S and have only had my iPhone 6 for 2 weeks and already seem to be having problems. I am not a rich person and cannot afford to be buying a new phone every time this on fails me. I, like most people, use my iPhone as my alarm clock. If my phone shuts down in the middle of the night I am late for work in the morning and I lose my job.
My phone has been shutting itself off when the battery reaches 50% power. Why? Is this a glitch? Do I need to return my phone and request a brand new replacement? Is the battery bad and does it need to be replaced? Am I doing something wrong?
Plus I only seem to have 1-2 bars of service (AT&T customer) when I would have mostly 3-5 bars with my iPhone 4s. What's going on? Is there something I can do to fix this?If you have a recent Backup of your Media/Data on your Computer with a current version of iTunes, you could Restore the iPhone 6 to Factory Settings and see if the Battery issue persists. To do this you could put the iPhone in DFU Mode by holding the Home button while plugging the lightning cable into the iPhone. You would then see a graphic on your iPhone 6 screen indicating you need to connect the iPhone to your Computer and iTunes for a Restore. Don't do this if you don't have a Computer and iTunes. Don't do this if you don't know your Apple ID and Password.
There are some preliminary things you could try first, if you choose...
A Reset ...By Holding down the Sleep / Wake (Power) button and the Home button at the same time until the white Apple logo appears on your iPhone 6 screen, then release the buttons but leave the iPhone alone until it fully Resets to your lock-screen.
You could also try a "Reset All Settings" but you would then need to add back your personal choices in Settings and perhaps add back your WiFi Password.
Also: If you are going to want to return the iPhone and get another one do it within the first 14-days.
However your iPhone is still covered and any warrantee issues would be covered beyond that within the warrantee period of longer if you purchased AppleCare Plus for iPhone. -
MacBook Shuts off abruptly, bad battery?
I booted my MacBook up as usual and began to use it without any problems. I click on a link to watch a YouTube video and it plays for several seconds and then the computer shuts off right after that with no warning. I had over an our and a half of battery life left before this happened. After it shut down I checked the battery on the back and I pressed the button and only one light blinked very quickly. This has happened on more than one occasion and the only way to boot the computer back up is to plug it back in to the AC adapter. Once I check the battery life while it's charging, it will something insane like 170mAh.
Is it time to get a new battery? My MacBook is a late '06 model and I've had it since January of last year. I calibrate it once a month and I don't deplete it more than half of its charge life. Any ideas?
Thanks!KBHenn...will you let us know what you find out if you contact AppleCare? I have the same problem it seems with the power outages. Mine goes out when I have 30-40% left it seems. The problem I'm seeing is that the calculator at the top of the screen is constantly changing and sometimes it's got crazy numbers like 200:00 hours left! It'll jump around all over the map. I also noticed the same thing as far as charging the charge says it'll take 28 minutes to fully charge and I come back in 10 minutes and it says 34 minutes to fully charge even though the % is going higher. Just weird.
I bought mine in Sept. '06. I'm not trying to hijack your thread here, but I'm curious as to how everyone's battery capacity is so high (mAh)? I've never checked mine until now and it's only 1267 Capacity. Do we simply have different batteries or is is this something that wears down over time? I'm in the same boat as you as having these issues, but once again since I'm over 300 cycles I'm curious to see if Apple Care will cover it. Good Luck!

I'm not sure if the problem has to do with iOS 6, but the problem started around the time I upgraded to it. I was playing Infinity Blade II when my iPhone shut off on me. I tried restarting the phone but once the lock screen showed (The battery was also shown to have a 64% charge), it quickly shut off again until I hooked the phone on the charger. This time the phone showed that it had a low battery and displayed the screen showing the empty battery, but then after a minute, the phone's lock screen appeared again with a 64% charge again. This keeps happening when ANY application is running when the phone is near 68%. The only time I've gone below that is when the phone was left overnight on standby. I have no idea what's going on or what's causing this. I could really use some help.
Also I've already restored my phone, and the problem still persists.Chris,
Definitely sounds like the battery controller is, at the minimum, out of synch with the battery itself. This can happen from with this type of battery.
But considering the age of the phone, I'd say it is more likely time to replace a nearly bad battery.
At least do this. Run the phone until the battery dies.
Power it up, and run it until it dies again.
If the battery is truly dead, upon power up you should get a large red dead battery symbol in the screen.
At this point plug it in to charge. DO NOT USE IT. Allow it to charge to 100%. This will re-calibrate the battery.
If it does not help, you should replace the battery.

Iphone 6 keeps shutting off randomly with battery left
my iPhone 6 is up to date its on IOS 8.1,3 and it keeps randomly shutting off with plenty of battery left like 30 or 40% and it will just turn off. I restarted it and backed it up and it continues to happen i don't know what to do.
Try to set it back to factory settings, without using the latest backup, in case the backup contained corrupt data.
Use iTunes to restore your iOS device to factory settings - Apple Support
If the problem comes back, your device needs to be checked by an Authorized Apple Service Provider or Apple:

MacBook Shuts off While Using Battery Power
Hello!
I have a white 13" MacBook from 2006.
But whenever I try to just run the MacBook on battery power, it shuts off within
1-3 minutes of use (Mainly using Safari).
I tried to reset the SMC, and changing the battery to a new one, but the problem
still persists.

When we switched the battery, the cycle count was 216 with the new battery.
But when we switched the batteries back, it was still a cycle count of 216.
We also tried to call AppleCare, but they didn't help very much...
Is there a defective part in my MacBook?Never mind with the question...
My dad mixed up the batteries and put the old battery back in the
old one, and the new battery stuck in the new one... =P
So, I tried switching the batteries by myself, and guess what?
I'm using the new battery right now - just on battery power!
(And it's not shutting off! =) ) -

Randomly Shutting Off When On Battery Power
So, I recently had my logic board replaced because my built-in audio out port wasn't working. I had this done more than a week ago, but just 2 days ago I was using it without being plugged in for over an hour (the battery indicator said I had about 50 minutes left of power) and then suddenly, it just shuts down. I hit the power key, and hear the startup "ding", and then hear it shut down seconds later. I plug it in, and start it up, and it works fine. Then last night I was using it on battery power again, and when the battery said 57 minutes left, it just shut down.
Could this be from my new logic board?Hi E,
Unlikely, but possible. More likely the batt is dying. Time indicators have never been known for their accuracy, and a batt starting to die increases that problem. Check the condition of the batt (Apple Menu:About This Mac:More Info:Power) and post back.

Why does my iPhone 4 shut off below 15% battery life?
I noticed my iPhone 4 battery was getting low today. I was given a message at 20% life. I then let the phone drop down to 15%.
I received a phone call, in which the call dropped. After I pressed the Sleep button, I was not able to wake the phone. Instead,
I had to plug it in for about 3 minutes, and Sleep/Wake + Home buttons to restart the device.
Is this just a miscalibration with my battery? Or is this some sort of defect. Other than this issue, my battery life has been fine and the device has been working as expected.hi CiChirs, could be two circumstances. that the battery is completely consumed and then the iphone is off, this is due to applications or updates. I had an iphone 4 for a long time and battery worked within normal limits. so check applications or settings of your iphone.
if the iphone is taking off with power, then you most likely have a short circuit, check the dock connector with a clean brush.
i hope it help.
