Battery dead unexpectedly

In the morning Coconut Battery showed 99% capacity of my MacBook battery, and at night it suddenly became 0%. Is there any chance of software mistake? There had been suspicious signs before the battery failure:
- before full charge the light on power adaptor would constanty change between red and yellow (between 99% and 100% of charge)
- Coconut Battery shows crazy statistics, like age of my mac - 3954875 months, 4 loadcycles.
That worried me, but the computer and the battery worked perfectly, and the battery lasted 3-4 hours without charge... Could you comment on the situation, please?

Check and see if you have battery update 1.3 installed.
MacBook/Library/System/Library/SystemConfiguration/BatteryUpdater.bundle
Leopard installs it. It is the MacBook Pro update.
If it is 1.3 drag it to the trash and then reboot. After you reboot you will be able to emtpy the trash. Once you have done that run software update and it should install Battery Update 1.2. You should reset the SMC (System Management Controller) after doing this.

Is my MacBook battery dead or is there something else going on?

Hi
My macbook has an "x" on the battery symbol and says "no battery available" on it. I have tried all suggestions I have found, like, replace battery, reset power management, reset PRAM and still have the "x". It wont even turn on now with the battery inserted and at teh moment I can only use it when battery is taken out and Im plugged into power using Magsafe adaptor. Laptop is about 2.5 years old. I did only notice this hapening after I installed SL but I dont know if that has anything to do with it. Is my battery dead and if so if I buy new battery will that fix it or could it be soimething else. I did check battery cycle count a few days ago and all was grand but I cant check it now as when I insert battery laptop turns off!
Any help is greatly appreciated. THanks

Do a reset of the SMC:

Try carefully cleaning the contact points on both the battery and the MacBook with a little bit of rubbing alcohol.
If neither of those do the trick, your battery is likely toast. If you are under the 3-year AppleCare, you can try calling and they may offer you a free replacement. If you get a replacement and the same thing happens--your MacBook shuts down with the battery in it or can't see a battery--then you have a much more serious hardware problem.

Go to System Preferences>Displays and set the resolution to "Best for this computer" (or something to that effect).

My computer (MacBook mid-2007) does not recognise the battery suddenly. A cross appears on the image. I have tried uninstalling and re-installing it but it didn't help. Is the battery dead?

Inspect the charging port area for dirt/debris/fluff build-up that may be preventing a good connection and use a wooden toothpick, soft clean toothbrush, or a can of compressed air to clean it. Also look for bent or broken pins. Try another cable and/or charger block (be sure to always use a genuine Apple certified brand) in a known good outlet. If you're using a USB port, try another port. If you're using a hub, try a direct connection. If you're using a USB port in the front of a desktop computer, try one in the back. If all these fail, make an appointment at your nearest Genius Bar to have the device evaluated.

I dropped my phone down the toilet then turned it off and left it in rice over night now it's saying battery dead and needs to be charged but I've read charing it is the worst thing to do, help please?

After taking a dip in my vest pocket in the washing machine for about 10 minutes, my nearly new 5S spent 5 days in rice and silica gel packets. It definitely dried out, but there is damage to either the battery or the circuit board because it turns on, and I continuously get a blue screen and it reboots every five minutes for a half hour, and then miraculously, it stays on and works perfectly. But I wound up having to fork over $700 for a new 6+. because I couldn't stand the rebooting any longer. I had no insurance, but I do now, Apple insurance, not carrier ins.

3gs reboots after 4mins on calls and shows battery dead then shows battery charged on restart any 1 have a fix please

Thought it had worked but soon found out it had not.
after further days of trying finally, solved it for me Yesterday.
turned off notifications when locked, and bingo, wow.
i have not turned off iCloud but location services are also off.
best thing to do I found was keep checking your usage, settings, general, usage, and flip down to bottom, if the standby and usage are similar there is a problem, if there is a big difference then all is ok. Just keep turning things off and on until the difference is very apparent.
something on my phone was keeping the phone alive even when turned off, and I think this was the phone repeatedly trying to update continually.
to me this is definitely down to the iOS, my wife has exactly same phone and iOS but hers doesn't have any problem and the battery lasts for days.
the guy at the Genius Bar told me to restore the phone via iTunes, not iCloud. This is because iCloud remembers the exact info from your phone and simply reinstates it when you restore, and this includes the iOS too.
when I get home from holidays that's what I'll do, or wait for iOS 8 in few weeks. But I'm so pleased I finally made it work, I was beginning to think ditch the phone and buy Samsung.
anyway anyone out there please try my final solution and let me know if it works for you?

Closed my charged MBP, opened later - battery dead...

I opened my sleeping MacBook Pro 2.0GHz last night and used it for a few minutes. I noticed the battery was mostly charged. (Not plugged into AC at the time.) I closed the screen and walked away.
The next morning (12 hours later) I opened the unit and it did not come on. I looked at the bottom and saw one flashing light for the battery meter. I gave it AC and tapped the power button and it restored from disk-saved sleep state and was back.
The battery fully drained itself thru the night. The bright white flashing sleep LED was lit when I saw the closed unit later last night.
This has happened once before.
- Did the unit wake and run down the battery?
- Was the LCD screen lit, while closed, until it died?
Anyone seen this behavior?
blakespot

I've had this happen to me a few times too.
Very annoying, because it makes me lose confidence that I can just shut the lid and come back to the computer later and continue my work.
This is almost Windows like (Windows notebooks have a notorious problem with sleep and waking properly without crashing) !!
I don't remember this problem with my Powerbook - the reliability of the sleep was one of the truly satisfying user experiences, never having to reboot OSX and having an instant on internet experience at home.
I'm wondering if it might be related to the hibernation feature that is implemented in the MacBook - you might have noticed that it takes 20-30 sec for the hard drive and fans to stop after closing the lid as an image of the memory is stored on the hard disk (for just in case the power runs out or the battery is taken out).
I don't like hibernation, because like most people after I close the lid of the computer I want to put it away and this 30 seconds is a critical time with hibernation for hard disk damage as 2 gig is being written to the hard disk. Any knocks and bumps could be catastrophic.
I'm going to turn of hibernation and will follow up whether the battery dead with lid closed problem continues.
Problem is that it is intermittent.

How do I disconnect my Facebook account from my Apple device that has iOS 6?
Open your Settings in iOS
Scroll down and tap Facebook
Tap your name > Delete Account
This disconnects your account from your Apple device, but it won't delete your Facebook account or deauthorize apps that you’ve already approved

N86 - Battery Dead Twice within 6 months time

Hi, I own a N86 at July 2009 and replace battery once in Sept 2009. Now 28 Nov my battery dead again. Seems like my battery dying every 2 months. NOKIA PLEASE RECALL THIS BATTERY!!!

It's not a question of heating the battery up once and it dying. Lithium-ion cells are slowly killed by oxidation and that increases at elevated temperatures. Given that most smartphone batteries are already being run ragged by going through their complete capacity every day (whether charged in one go or charged several times), it doesn't take much time sitting in a glove box in a warm part of the world before the battery will keel over.
I absolutely agree that only doing full discharges isn't great for the battery's lifespan, and batterires should be charged frequently instead, but six months is a heck of a short time.
Help I'm trapped in a sig factory.

Reversed charging indicator when battery dead

When my iPhone 4S (ios7) has a dead battery, the charge indicator sometimes works backwards--when the charger is plugged in it shows "dead battery"; when I unplug it, it shows "charging". It doesn't appear to charge when it does this.
It's happen several times, and each time it's come right after home/power resetting, although being dead it doesn't give any immediate indication that it has reset. I just mean that if I don't reset, it never charges; if I do the reset, and leave it plugged in for a while, it seems to come right.
It's a problem becase I never know it's happened until I go to pick it up thinking it's been charging, only to find it needs a reset and another charge.
The phone is a couple years old, but the battery is generally in good shape and normally gives me no trouble charging or in terms of charge time.
Thanks for any thoughts!

Hello Mik,
It sounds like your phone is charging incorrectly and behaving unexpectedly. I would start by resetting the phone with the following info:
To reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo.
From: Turn your iOS device off and on (restart) and reset
http://support.apple.com/kb/ht1430
If that does not correct the way that the phone is charging, I would next back up your device to iTunes with this article:
iOS: How to back up and restore your content
http://support.apple.com/kb/HT1766
And restore it from your backup with this article to put it into recovery mode and install a fresh iOS copy on the phone:
If you can't update or restore your iOS device

Thank you for using Apple Support Communities.
All the best,
Sterling

Why my Iphone 4S battery dead quicker than others!

Hello guys:
At the start i have to say i am a Janpanese guy which means what i say may have some mistacks. Please dont pick on me.
I bought an iphone 4s 4 days ago. I find out my phone only need charge 3 hours at the first time and was up to 100 percent, I took it off and used for 4 and 26min on 3G Internet and 14 hours standby times and it is complete dead. I did follow the battery docter this program turned off applications that waste battery time. Such as wifi iclound sifri and i put my phone brightness at about 1/3.
Second day i charged my phone for 6 hours and it is the same! Eventhough i put at standby it still use the battery.
What can i do for this?
I check some people said restore the system might help and i am doing now, is that ok? Or is that have something that i can do about?
Thank you for everyone.

iOS 5 have so many things that can do that. Wifi conections, GPS, Ping, Push mail...
My advice is that you use that things only when you have to use them. I calculated that mi iPhone 4S can be 100h in stand by without wifi, GPS, Push mail and turning of the game center.
I think that batteries are not ready for the tecnology of this time.

Mid-2010 battery dead after 629 cycles?!?

Hi,
My mid-2010 Macbook Pro 15" battery is seemingly dead after only 629 cycles. It says that the condition is "replace now" and the green indicator lights flash when I press the button on the side. It was working fine, and then I didn't use the computer for a little while, and now the battery doesn't charge and it has to be plugged in.
I'm hesitant to think the battery has just failed, because like I mentioned, there are only 629 cycles on it, and it was working prefectly before, and it seems very sudden.
Any help/thoughts/suggestions are appreciated!
Thanks!

Make an appointment at the genius bar. Have you fully discharged and recharge fully over the battery's 2 yr life? This is good to do a few times a year.
