Mbpr shutting off with 50% battery

Hi, i am generelly a computer nerd, and i am very good with computers, and i help alot of people with them, but this one thing is just stumping me! My MacBook Pro Retina just randomly shuts off thinking its battery is depleted when the battery status indicator says that it has 50% battery. is it just a faulty connection, or something else? TIA!

    Hold down home and sleep buttons for about 15 seconds.   If you don't see the Apple logo, plug phone into wall charger for at least 15 minutes.

  • My iPhone 3GS running iOS 6 shuts off with 60% battery. Do any of you know any fixes, or at least what might be causing this?

    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.

  • Mini 2140 shutting off with any kind of movement or jarring rendering the battery useless

    Hello, I have about 260 of these devices and I am running into an issue with the 6-cell extended life batteries.
    We have replaced the 3 cell standard life battery with the 6 cell extended life battery. Now for the issues. I have had several of these come to me with the same problem. When a using sets the machine down it will instantly power off. Almost as if you pulled the battery out. Now, once the machine shuts down you can power it back up just fine. Of course it will shut down instantly again if you touch or jar the battery at all.
      Now some of them get so bad that the machine will not power on and I have to replace the battery with a new one. Does anyone know what cause this? Is there a fix for this?
    I am running
    HP Mini 2140
    XP Pro SP3
    6 cell extended life batteries
    I do have 3 cell batteries that we use as back ups. I have never had one of these go bad so far.
    They have been in use since August of 2009
    Please let me know if anyone else has seen these issuses.
    If you need any more info just let me know.

    wouldn’t be concerned with this if it wasn’t wasting the battery.
    The battery is not being wasted.
    Apparently this mini ipod is suppose to have 14 hour battery life
    That is the "estimated" time of battery life.
    Depends on a lot of different factors.
    As a matter of fact, last night ~11 PM, I turned on my fully charged Mini, set it to Repeat All and hit play. I turned on Hold, set it on my dresser & let it go. on & let it go.
    It was still running tonight at 8:30 PM. It finally died within the last 1.5 hours or so. 21-23 hours is how long I got out it.
    but mine is much less since it doesn’t properly shut off.
    It is properly shutting off. Your battery is probably going bad.
    Your iPod is working exactly as it is supposed to work.

    My iPhone 4S shut off with a 62% battery life and hasn't came back on yet. I've charged it and all it just won't come back on at all. Is this a common problem? Is this covered under my 1 year warranty?

    No it is not common.
    Most have no issues.
    Have you tried basics from the manual?  Restart, reset, restore?
    The warranty covers defects.  If the iphone is defective, then they would replace it.

  • 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.

    It strikes me as odd that your charger blinks from amber to green while charging rather than glowing a steady amber. Does it fully charge your battery--i.e. do all the lights in the battery light up, regardless of what it says in the menu bar?
    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!

  • 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.

  • IPhone 6 shuts down with 40% battery life

    Hello,
    I have an iPhone 6 (64 GB) on T-Mobile running iOS 8.0.2 that shuts off when the battery indicator says about 40%.  I could be using it like normal, then it just shuts down and flashes the red battery logo and tells me to plug it in.  It comes right back on when connected to power and then it is good to go.  I haven't tried to run it back past 40%, again, but the phone consistently powers down around the 40% mark.
    I set up the phone with an import from my iPhone 5S and I got into the "death spiral", where the phone was stuck in a constant reboot unless I did the hard restart (power and home button until the phone restarted).  I think I fixed that by deleting the apps that were loaded from my 5S backup and installing them fresh from the app store. 
    I am restoring the phone right now and will load the backup from the iPhone 6.
    Has anyone else had this problem?
    Thanks,
    Matt

    It could be an issue with the battery calibration. I would go threw with the restore, set the device up as new, then restore from the backup. If that does not work then it is hardware related and most likely a battery issue. If you have an Apple Retail Store near you could take it in there for battery replacement, or you could call Apple Care and they have mail in options. You will want to make an appointment for the Apple Retail Store if you choose to go that route.

  • IPhone 5 shutting down with 20% battery life left

    My iphone 5 is turning off with 20% battery life showing. I've done all the updates. When I plug it in, battery life immediately jumps to 30% left. Any clues? It's not overheating and usually I'm just typing a text message. It's shut down twice now as I try to send a picture with the message. Thanks in advance for any help.

    This usually means that your battery gauge needs to be calibrated. Apple actually recommends doing this on a monthly basis, but the advice is buried in the battery info tiphttp://www.apple.com/batteries/iphone.html.
    What you need to do given your current problem: When the phone shuts off and it isn't down around 1%, connect to a charger for just a minute or 2, or wait 15 minutes, then reboot the phone (hold HOME and SLEEP until an Apple logo appears). Continue running the battery down until it shuts off around 1%. If it goes off above that value repeat the above process until you really do get to 1% (this will rarely take more than 2 tries).
    Once it has turned off and won't restart or reboot charge it with the wall charger for 4 hours without using the phone. This should fix the problem for the moment. Going forward, about once a month run the battery all the way down and charge for 4 hours. This should prevent the problem from recurring.
    If this does not work your battery may be failing. As it's still in warrantly take it to an Apple store for repair."
    I am having the same problems with my phone and found this discussion last night and tried to follow this procedure but I could not get my phone to turn on and run down to 1%. It shut itself off from 15%-7% almost instantly. I rebooted it as recommended by others and turned it on and let it shut off until it got down to 7% then it would no longer turn on. even after sitting for a little while. I have charged my phone to full overnight with the charger that it came with and will wait to see if the problem persists. I am very frustrated with this and found out that my phone is a few days outside the 1 year warranty. If anyone has had this situation and found a fix without getting a new phone, please let me know.

  • I Phone 4 with I OS 4.2  shuts downs with 30% battery still remaining.

    Hi,
    I have been an Apple fan for years, But recently my new I Phone 4 has been giving me a lot of trouble.
    I purchased the Phone in Oct'10, it was working great till last week. All of a sudden my phone automatically switches off with 30% battery still remaining. when I plug in the charger it starts from 30% percent battery and goes all the way till 100%. but when I start using it, it lasts till 30% and then kaput. no warnings, no signs just switches off and all attempts to switch it back on fail till the charger is plugged in and, then it will start still showing 30% battery and then charging all the way till 100%.
    I wonder if this is a software or a hardware issue, I am worried as the Phone was purchased in Singapore where I used to live but have moved back to my home town New Delhi in India. I can't go back to Singapore to get it fixed and if I go to a service center here I don't know how much I might have to shell out.
    I'm desperately looking for some help.
    Thanks
    DevRachit.

    to be honest these are the solutions that may or may not work..
    first thing I would try is rebooting the phone by holding the sleep/wake button and home button for 15 seconds until you see the white apple logo
    if that doesn't work I would restore from backup and if that doesn't work I would restore as new if all that fails unfortunately you would need to take it back to the country you purchased it for replacement

  • 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
