From the above link...
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

Do that repeatedly and you soon will have a completely useless battery on your hands.
Solution - charge it up BEFORE it auto shuts off on you.
Repeatedly deep cycling a Lithium cell will ruin it much faster than charging it when only partially discharged.

My iPhone 5 shuts down with a 10% charge remaining, is there a fix?

After my recent software upgrade my iPhone 5 shuts down with 10% charge remaining. This has never happened before. Is there a fix?

The battery gauge probably needs to be recalibrated. It "thinks" there is more charge in the battery than the battery thinks there is.
When it shuts off charge for just a minute or two, then restart (hold HOME and SLEEP until an Apple logo appears). Deliberately run the battery down until the phone shuts off at 1%. If it shuts off above 1% repeat the above until you get to 1%. Then charge for 4 hours with the wall adapter without using the phone. This process will recalibrate the battery gauge.
To prevent this from happening again about once a month run the battery all the way down to 1%, then continue until the phone shuts off. Apple recommends this in their battery help article, but they don't say why you should do it. The have some hokum about "keeping the electrons moving." Honestly! The iPad battery tip gives the correct reason.

Battery powers down with use while charging

Battery takes hours to charge but powers down if pluggwed in

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.

Ref:iphone 3G.I was visiting the US last week.One day my iphone battery completely drained overnight.I re-charged it but ever since it has either come up with a message saying it's registering, or that I need to register it.It was registered years ago.

Ref: iphone 3G. I was visiting the US last week. My iphone battery completely drained overnight. I re-charged it but ever since it has either come up with a message saying it's registering or saying I need to register it. I'm concerned that if I re-register it on itunes I'll lose all my data. I originally registered it a couple of years or so back, when it was new. Any advice much appreciated.

Thank you for quick reply. The data is still there - every so often when I switch it on, it comes up with the main icon screen, rather than the emegency calls only screen (which it does most of the time), and I can get to my contacts, photos, and so on, but it won't connect to any mobile/cell network provider, including my network here in the UK - O2.

My Iphone gets hot and wont hold a charge for more than 8 hrs

My Iphone 5c gets hot even when i dont have a protective case on it but it is worse when it is charging. The battery will only hold a charge for at most 8hrs, i have taken it into the store and they always say nothing is wrong with it. I find that hard to believe since my old iphone that was 2 years old lasted longer. I have already turned my backlight down and turned off notifications. Any ideas?

Charging has always been recommended without an iOS device in a case...many of those do not allow heat to dissipate.
Turn down screen brightness, turn off things you don't need, like Bluetooth if not being used, change the Mail push timing so it is less frequent...all things that use energy should be stretched out to save battery time.

IPod mini battery shows empty even after it charged for hours, but works?

i'm new to this, i borrowed someone's iPod mini and when battery ran out i put it to charge to my new macbook, charged for a few hours, lightning bolt showed all the while even if sometimes the indicator showed full and other times it showed that it was charging. now that i've disconnected it, it shows empty but it still works, can anyone help?
I read here http://www.vsa.cape.com/~danh/ipod.htm that this could happen, that the battery indicator could start showing full after 20 minutes... should i start panicking or not?

HT201272 I downloaded previous songs frm my iPad on the iPhone and I realized I was being charged for this when I thought it'd be free

Hello I had a bunch of songs on my iPad and a friend told me I can re-download them onto my iPhone with the username I have and I did that and I was charged for them. I really wish I knew I would of been charged for this or else I would of had to wait until I can do so without being overdrawn in my bank account.

You can, but you need to click the "Purchased" section of the iTunes Store to see your previously purchased stuff (you'll see little "cloud" icons to indicate your just downloading, not repurchasing). If you're on your phone, you click "More" then "Purchased" and you'll see everything there.
You should contact Apple support. Using iTunes for the Mac or PC, go to the iTunes Store, click your account name to get to your account section, then you can look at your purchase history and "report a problem" for a specific purchase.

HT1296 My battery seems to be not holding charge for very long, I have a model 4(s?) and have it in service for 21 months. What do I need to do to save my information?

What is usual life of battery, what do I need to do to rapidly get my phone back in service, most importantly, what do I need to do to preserve all of the information on my phone, or how do I do a miror image of the phone's stocked info.

Hello there, Jean-Marc Peladeau.
The following Knowledge Base article gives a few pointers for troubleshooting your battery issue:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Specifically:
Battery life seems short
Click ( www.apple.com/batteries/iphone.html) for tips on how to prolong iPhone's battery life.
Try turning iPhone off and then on again.
Connect iPhone to iTunes and restore iPhone.
If the screen shows a low-battery image, the battery is low on power and needs to charge for up to ten minutes before you can use it.
When charging iPhone, make sure to leave it charging until it is fully charged. You'll know the battery is fully charged when the battery icon in the upper-right corner of the screen looks like this .
Note: When charging using a computer, don't connect iPhone to a keyboard. Also, the computer must be turned on and not in sleep or standby mode. If iPhone is connected to a computer that's not turned on or is in sleep or standby mode, the iPhone battery may drain.
Note: Charging with a FireWire-based power source is not supported, except on original iPhone.
Additionally, in regards to your question about backing up your device, feel free to review the following:

My iphone battery has ran out and wont charge all i see is the red battery icon , what shall i do?

my iPhone 4 was working fine then the battery died as it normally would and now iv tried to charge it and it will not charge all it shows on the screen is the red battery icon i left the phone to charge so it can turn on by its self for about 30-1 hr but still didn't come on, then i thought the problem was probably the charger so i switched chargers to a much newer one but still no sign of it coming on, what should i do?

Hold the HOME and SLEEP buttons at the same time until an Apple logo appears (10-15 seconds).

Mac falls asleep when battery gets down to roughly, half charged

it falls asleep once it gets to this point, and then i wake it up and the charge has gone right down.
Does it need to be calibrated? or is the problem bigger than that?

Most likely you need a replacement. There are known issues with MBP batteries, and an extension of the battery warranty to 2 years, as described on this page:
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
Go to System Profiler (Apple menu > About this mac > More info) and click on Power. If the Full Charge Capacity is less than 4400 mAh for a 15" or less than 5000 mAh for a 17" MBP, your battery is failing. If your Cycle Count is less than 300, your battery is failing prematurely and Apple will replace it for free. If that's the case, call Apple or visit an Apple Store for a free replacement.
