More help understanding Battery Charge Info

Charge Information:
Charge remaining (mAh): 2797
Charging: Yes
Full charge capacity (mAh): 2816
Health Information:
Cycle count: 388
Condition: Good
Battery Installed: Yes
Amperage (mA): 322

What does charge remaining @ 2797 and Full charged capacity @ 2816 mean? Is it near the end? How did I get 388 cycle counts? Any info greatly appreciated.

Welcome to the Apple discussions.
A new lithium battery has a capacity ranging from around 3600 to 4500 mAh (see http://en.wikipedia.org/wiki/Ampere-hour for definition of mAh). Over time, this capacity declines until it won't hold a charge long enough to be useful, at which point the battery is replaced. Your battery total capacity is now 2816 mAh, and has been run a little on battery power, so the charge remaining is 2797 mAh, and the power adapter is plugged in and charging the battery.
A cycle is a discharge/charge of the battery. Here's an Apple note that may help: http://www.apple.com/batteries/notebooks.html . One thing it says is that a properly maintained battery should have 80% of it's capacity after 300 cycles.

Battery charge info in status bar is incorrect! HELP!

This issue started a day or two ago and at first I thought it was no big deal, but it's actually quite a problem! I've got a 15.4" Macbook Pro that I bought in May, and have never had any problems up until this point. But then I noticed that the icon in the status bar where it says the percentage of battery charge and says whether it's running off battery or it's plugged in - it's WRONG. It's stuck at 99% and says it's plugged in. All the time. Even when it's almost dead and not plugged in. So I can't tell how much battery charge it has left. In all of the places where you can view info about the battery, the info is wrong - it says it's fully charged, that I have a long time left, etc. but it's not true. So now it can completely out of batteries and shut down and I won't be able to tell that it's running low.
Has anyone had this problem? What do I do? Is this a software or a hardware issue? HELP!

Have you tried resetting the PRAM ?

Is there something wrong with my battery? (have battery charge info)

Have had my Macbook Pro for a year and a half now, and thought I was having over-heating problems a few months ago but they said it was "normal." But lately I have been noticing that with a full charge the battery will only last (on average) 1.5-2.5 hours (not video, just school work internet browsing and typing documents), and that's not as good as it was when I originally bought it...in fact, much worse (as I know batterys diminish over time).
Here is the battery info: (from coconutBattery)
Current Battery Charge: 3900 mAh
Maximum Battery Charge: 4187 mAh
Current Battery Capacity: 4187 mAh
Original Battery Capacity: 5500 mAh
Battery-Loadcycles: 339
Age of your Mac: 17 Months
So the max battery charge has dropped from 5500 mAh to nearly 4000 mAh in just over 300 loadcycles? That seems a little more than "average"...and it just feels that the battery is draining quite quickly.
I have Applecare extended warranty, will this be covered based on the battery statistics info? Or am I just over-reacting?

The battery in your specific machine should generally hold its full charge up to about 300 cycles depending on use... then it will drop down to roughly 80% and gradually decline. Going from a capacity of 5500 mAh to 4187 mAh is a drop of about 24% (or about 76% of the original capacity). These numbers aren't really out of wack for normal battery wear. Some people will experience slightly worse... others slightly better... but I don't see an issue considering the age and cycle count on your battery.

My iPod displays black & white battery charge icon and sad iPod face. help!

I plugged my iPod into an older iMac; it froze and had to be restarted.
I restarted it and started listening on shuffle.
It would skip through all of my songs without me pressing any buttons.
I restarted again and it worked fine.
I came home and plugged it into my 10.3.9 iMac and the tracks started skiping and barely playing on iTunes.
I tried to eject it, but it wouldn't...so I unplugged it.
I then restarted it, but after the silver-on-black iMac icon came up, the sad iPod face showed.
So I pluged it back into the computer. It spontaniously restarted when I tried all of the steps of restarting and reinstalling.
Then it just displays a black& white old battery charge icon with a thunder bolt that flickers on the screen now and then.
And continues to restart itself with first the apple icon turning into the sad ipod face and then into the battery charge icon.
I really do not want to restore my iPod. I am hoping to keep my files but at this point, my future is bleak.
This happened last night. They said it might just be my battery so I kept it plugged in for about 10 hours. Nothing.
What can I do?
Please, please help.

Hello,
If a sad iPod icon or an exclamation point and folder icon appears on your iPod’s screen, or with sounds of clicking or HD whirring, it is usually the sign of a hard drive problem and you have the power to do something about it now. Your silver bullet of resolving your iPod issue – is to restore your iPod to factory settings.
http://docs.info.apple.com/article.html?artnum=60983
If you're having trouble, try these steps at different levels one at a time until the issue is resolved. These steps will often whip your iPod back into shape.
Make sure you do all the following “TRYs”
A. Try to wait 30 minutes while iPod is charging.
B. Try another FireWire or USB through Dock Connector cable.
C. Try another FireWire or USB port on your computer .
D. Try to disconnect all devices from your computer's FireWire and USB ports.
E. Try to download and install the latest version of iPod software and iTunes
http://www.apple.com/ipod/download/
http://www.apple.com/itunes/download/
F. Try these five steps (known as the five Rs) and it would conquer most iPod issues.
http://www.apple.com/support/ipod/five_rs/
G. Try to put the iPod into Disk Mode if it fails to appear on the desktop
http://docs.info.apple.com/article.html?artnum=93651
If none of these steps address the issue, you may need to go to Intermediate level listed below in logical order. Check from the top of the lists to see if that is what keeping iPod from appearing on your computer in order for doing the Restore.
Intermediate Level
A. Try to connect your iPod with another computer with the iPod updater pre-installed.
B. Still can’t see your iPod, put it in Disk Mode and connect with a computer, instead of doing a Restore on iPod Updater. Go and format the iPod instead.
For Mac computer
1. Open the disk utility, hope your iPod appears there (left hand side), highlight it
2. Go to Tab “Partition”, click either “Delete” or “Partition”, if fails, skip this step and go to 3
3. Go to Tab “Erase” , choose Volume Format as “MAC OS Extended (Journaled), and click Erase, again if fails, skip it and go to 4
4. Same as step 3, but open the “Security Options....” and choose “Zero Out Data” before click Erase. It will take 1 to 2 hours to complete.
5. Eject your iPod and do a Reset
6. Open the iPod Updater and click “Restore”
For Window computer
Go to folder “My Computer”
Hope you can see your iPod there and right click on the iPod
Choose “Format”. Ensure the settings are at “Default” and that “Quick Format” is not checked
Now select “Format”
Eject your iPod and do a Reset
Open the iPod Updater and click “Restore”
In case you do not manage to do a “Format” on a window computer, try to use some 3rd party disk utility software, e.g.“HP USB Disk Storage Format Tool”.
http://discussions.apple.com/thread.jspa?threadID=501330&tstart=0
C. Windows users having trouble with their iPods should locate a Mac user. In many cases when an iPod won't show up on a PC that it will show up on the Mac. Then it can be restored. When the PC user returns to his computer the iPod will be recognized by the PC, reformatted for the PC, and usable again. By the way, it works in reverse too. A Mac user often can get his iPod back by connecting it to a PC and restoring it.
Tips
a. It does not matter whether the format is completed or not, the key is to erase (or partly) the corrupted firmware files on the Hard Drive of the iPod. After that, when the iPod re-connected with a computer, it will be recognized as an fresh external hard drive, it will show up on the iPod updater.
b. It is not a difficult issue for a Mac user to find a window base computer, for a PC user, if they can’t find any Mac user, they can go to a nearest Apple Shop for a favor.
c. You may need to switch around the PC and Mac, try to do several attempts between “Format” and “Restore”

Advance Level
A. Diagnostic mode solution
If you have tried trouble shooting your iPod to no avail after all the steps above, chances are your iPod has a hardware problem. The iPod's built-in Diagnostic Mode is a quick and easy way to determine if you have a "bad" iPod.
You need to restart your iPod before putting it into Diagnostic Mode. Check that your hold switch is off by sliding the switch away from the headphone jack. Toggle it on and off to be safe.
Press and hold the following combination of buttons simultaneously for approximately 10 seconds to reset the iPod.
iPod 1G to 3G: "Menu" and "Play/Pause"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Menu" and "Select"
The Apple logo will appear and you should feel the hard drive spinning up. Press and hold the following sequence of buttons:
iPod 1G to 3G: "REW", "FFW" and "Select"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Back" and "Select"
You will hear an audible chirp sound (3G models and higher) and the Apple logo should appear backwards. You are now in Diagnostic Mode. Navigate the list of tests using "REW" and "FFW". The scroll wheel will not function while in diagnostic mode. For further details on Diagnostic mode can be found at http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/
Try to do the 5in1, HDD R/W and HDD scan tests. Some successful cases have been reported after the running the few tests under the Diagnostic mode. In case it does not work in your case, and the scan tests reports show some errors then it proves your iPod has a hardware problem and it needs a repairing service.
B. Format your iPod with a start disk
I have not tried this solution myself, I heard that there were few successful cases that the users managed to get their iPod (you must put your iPod in disk mode before connecting with a computer) mounted by the computer, which was booted by a system startup disk. For Mac, you can use the Disk Utility (on the Tiger OS system disk), for PC user, you can use the window OS system disk. Try to find a way to reformat your iPod, again it does not matter which format (FAT32, NTFS or HFS+) you choose, the key is to erase the corrupted system files on the iPod. Then eject your iPod and do a Reset to switch out from Disk Mode. Reboot your computer at the normal way, connect your iPod back with it, open the iPod updater, and hopefully your iPod will appear there for the Restore.
If none of these steps address the issue, your iPod may need to be repaired.
Consider setting up a mail-in repair for your iPod http://depot.info.apple.com/ipod/
Or visit your local Apple Retail Store http://www.apple.com/retail/
In case your iPod is no longer covered by the warranty and you want to find a second repairing company, you can try iPodResQ at your own risk
http://www.ipodresq.com/index.php
Just in case that you are at the following situation
Your iPod warranty is expired
You don’t want to pay any service charges
You are prepared to buy a new one
You can’t accept the re-sell value of your broken iPod
Rather than leave your iPod as paper-weight or throw it away.
You can try the following, but again, only do it as your last resort and at your own risk.
Warning !!!! – It may or may not manage to solve your problem, and with a risk that you may further damage your iPod, which end up as an expensive paper weight or you need to pay more higher repairing cost. Therefore, please re-consider again whether you want to try the next level
Last Resort Level
1. . Disconnecting the Hard Drive and battery inside the iPod – Warning !! Your iPod warranty will be waived once you open the iPod.
In Hong Kong there are some electronic shops offering an iPod service for Sad iPod, the first thing they do is to open up the iPod’s case and disconnecting the battery and the Hard Drive from the main board of the iPod. Wait for 5-10 minutes and reconnecting them back. The reason behind which I can think of is to do a fully reset of a processor of the iPod. In case you want do it itself and you believe that you are good on fixing the electronics devices and have experience to deal with small bits of electronic parts, then you can read the following of how to open the iPod case for battery and HDD replacement (with Quicktimes)
http://eshop.macsales.com/tech_center/index.cfm?page=Video/directory.html
2.Press the reset button on the Hard Drive inside the iPod – Suggestion from Kill8joy
http://discussions.apple.com/thread.jspa?messageID=2438774#2438774
Have I tried these myself? No, I am afraid to do it myself as I am squeamish about tinkering inside electronic devices, I have few experiences that either I broke the parts (which are normally tiny or fragile) or failed to put the parts back to the main case. Therefore, I agree with suggestion to have it fixed by a Pro.
2. Do a search on Google and some topics on this discussion forum about “Sad iPod”
What should I do with my iPod? Send it or keep it?

I am not suggesting that you should follow as well, but just read them as your reference. You are the person to make the call.

MacBook Pro battery had accumulated more than a 1000 charges, and stopped functioning unexpectedly. Went and got the battery replaced. Just saw that SMC Firmware 1.6 update deals with this. Possible to get my money back?

MacBook Pro battery had accumulated more than a 1000 charges, and stopped functioning unexpectedly. Went and got the battery replaced. Just saw that SMC Firmware 1.6 update deals with this. Possible to get my money back?

The firmware update corrects an error that may occur, however the techs would have checked the condition of the battery prior to installing a new one. If the battery was questionable, the firmware update was really not too important.
You can check the battery condition by going to the apple, left side of the menu bar, About This Mac, More Info, System Report, Hardware, Power and see what it says about Cycle Count, Condition, Capacity: Condition anything but Normal needs to be checked and may need to be replaced.
The cycle count of 1,000 charge cycles is the typical life of a Lithium-Ion battery, the point at which the capacity drops to 80% of the as built capacity.

My info for battery charging says "Not Charging" when it is charging as per dashboard widget.

My info for battery charging says "Not Charging" when it is charging as per dashboard widget. Since change to lion all slowed down do I need more ram ( have 2 gig). Lost some icons in web site icons and other random icons. So far SL better.

Yeah, it was purchased in August 2008. I'm not really sure what a charge cycle is, but I do plug it in and unplug it a lot to a power source. Mainly because I keep my computer on most of the time (either on or on sleep). So between taking it to classes and stuff, I'll recharge in between and when it's really low, otherwise I run it off the battery most of the time.
On a sidenote, I have went to that information thing about about the battery after letting it sit plug in for a few hours, and now it has this information:

HT4060 Should I let the battery run down before charging my iPad or iPhone to help the battery last longer?

Should I let the battery run down before charging my iPad or iPhone or iPod Nano to help the battery last longer? I took a class at Verizon and they said let it drain completely and it would last longer. Thanks

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. Also look at The iPad's charging challenge explained http://www.macworld.com/article/1150356/ipadcharging.html

My ipod touch seems to be jammed on the battery charging screen it has the spining symbol like its trying to load something. I cannot turn it off. I have tried hooking it up to itunes to reset it, but it seems to jam itunes as well. Any help would b much appreciated.

Try:
- Resetting the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Then connecting it to your computer. If iTunes see it, restore the iPod via iTunes
- If no sceen in iTunes, see if placing the iPod in recovery mode will make it visible so you can restore it. For recvery mode see:
iPhone and iPod touch: Unable to update or restore
- Let, let the battery fully drain and then charger and try again.

It probably means you don't have enough available storage on your phone. It takes space to store the download - THEN unpack it. Best method is to use a computer with iTunes (This allows you to back up on your computer as well).
PLEASE: Do not purchase iCloud storage space - this will not give you more room for the iOS 7.1 installation.

Hello,
I can not get my battery charger on my new Gx700 Performance? (GX700-012)
In status indicate : " 95% available but no in charge" and led is no lit.
thanks

Don't trust the Windows status indicator too much...it's know to be very inaccurate.
Anway, just use your notebook until it shutoff due to empty battery, then recharge.
Good chance the indicator will show a better indication.
