IPad shuts down with still 11% battery.

I have an iPad 2 which is 4-5 months old. It has been running great until the recent problem.
I use it 8-10 hrs every day, discharge it frequently, and never leave it plugged in overnight and charge it to full capacity almost every other day...
It has recent iOS and have also tried rebooting.
Now, the recent problem, it turns off at 11% power. few days earlier the same happened at 9% power.
I tried plugging it and trying to restart and then unpluggin immediately. Again, it shuts off at 11%.It doesnt even display the "low battery" warning before shutting.
Is this problem usual after 4-5 months of usage? Can i do something to fix it?
Thanx a lot!

You may need to recalibrate the battery. See link below.
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

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!

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.

Macbook Pro shuts down with a full battery, resets date

Hey I have a mid 2011 Macbook Pro that has been shutting down randomly. It'll have a full battery, but shut down when I unplug it or even sometimes when it's still plugged in. Every time I start it up again, the date is changed to Jan. 1 2008 and there's a notification that because it's set to that date, some applications may respond "erratically". It did this for about 2 weeks, then was back to working fine for about a month and now it's started up again.
Today when I turned it back on after it shut down, a notification said to rebuild the iPhoto library. I didn't really know what it meant so I clicked OK because I thought it would help. Instead it erased my entire iPhoto library and shut down again. Thankfully I had my picture backed up!
I have a Genius appointment tomorrow, but was curious if this is happening to anyone else or if anyone has a diagnosis!
Thanks!

Ok so I took it to the Apple store today and the guy was mildly helpful. He said I'm probably running too many programs at the same time and it's depleting all the power. Kind of ridiculous in my opinion because I feel like MacBooks are built to handle checking your email and editing a picture at the same time. He checked all the systems with disk utility and everything, including the battery, came back in good shape. Anyway, it worked fine (of course) when I was with him, but the moment I got home it was worse than ever. Now, even when plugged in, it'll only stay on for a few minutes, if that. It won't turn on at all if it's not plugged in. It plays this game where it shuts itself down then turns itself back on then shuts down again over and over. Any ideas? I feel like I'll just have to take it back to the store.

MBP 17": Sudden shut down with plenty of battery, then battery warped

My battery warped while in the computer and I had a hard time getting it out. This was after my computer began shutting down without any warning while on battery power. I called my local Apple reseller this morning and was told to bring the computer and battery in so they could check it out. When I arrived, they told me that they had a simple test which they had to run on the computer with the warped battery inserted. Pass: no free replacement. Fail: Replace the battery for me.
The USB gadget they used indicated pass, so I was out of luck. In other words, they said that my battery tested "OK". "But it's warped!", I said. They agreed, but only offered to sell me a new one for $129.95 + tax. I said that I wanted to complain to Apple since the battery was obviously on the way to a more serious problem and might damage my MBP. They said that they would complain if they were me....
I was in a bind since I need to travel soon, so I bought a new battery.
The explanation was that Apple recognizes that there is a problem, but since my MBP/warped battery passed the required Apple test, they couldn't replace it for free. The battery was so warped that I my computer wobbled on my desk! This is crazy! Those of you who have been reporting the sudden shut down had better be very careful. You may be on your way to a potentially catastrophic event in which the battery failure does serious damage to your MBP. I've read some real horror stories about this on the net.
Are you reading this, Apple?
-jr

Just a follow-up regarding my old battery:
I put it in the box that the new one came in and intended to recycle it. Then I forgot about it and looked at the box just now. The other side of the battery also warped to the point that I couldn't get the box out of the sleeve that fits around it without tearing it (which I did).
Pretty scary looking. Silver pouches (cells?) exposed and deformed. Afraid of the thing at this point. A fire hazard?
Out of the house in a can it went until tomorrow morning when I will get rid of it legally.
BTW, my deformed and potentially hazardous battery only had a cycle count of 137 when all this fun started....
Please be careful.

Why does my macbook pro keep shutting down with a charged battery

Why does my Mac book pro keep shutting down? I lose everything I am working on when it shuts down help

kva,
which model MacBook Pro do you have? Is it running Mac OS X 10.5.5? If not, which version of OS X is currently installed on it?
Are you running on battery when it shuts down, or are you running on AC when it shuts down, or does it happen in either case? Which app are you working in when it shuts down? Does it happen only in that app, or does it happen no matter which app you’re working in?

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.

Moments later I turn it back on and the same battery life still appears. It sometimes happens over and over until I leave it alone for a while (still not charging), and then it works.

I think you might get a new phone instead of repairing it as it takes time and you said the repairing center is far from your living place

Is it possible that you or someone who knows your iCloud sign on went into the Find My iPhone app and erased your device via iCloud? Because that is what that message is saying.
Have you tried to sign on with your Apple ID and password?
Was it online prior to this incident happening?

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
