Is it good or bad for the battery to keep the powercord plug in after complete charge.

It does no harm. It won't over charge.

Using a power bank good or bad for iphone battery lifespan?

I currently use iphone 5, i see many aid product made now such as power bank,
but a question comes in my mind , is that good or bad for our battery lifespan?

Are you referring to cases with battery packs in them?
If so, most have a switch to turn the battery in the case on or off.
Having the iPhone or any phone in a battery case is neither good or bad. It is merely a way to extend the "life" of the device between charges without the need to physically plug the device in as there is always the extra battery onboard.

Does it adversely effect the battery to keep the IPad plugged in when fully charged?

Copied from Texas Mac Man ...
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

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.

I forgot my ipad on charge after 100%,is this bad for ipad battery?

Once the battery was fully charged, the smart circuitry stops charging the battery. Power is then used just for running the device, and the charging circuits will not cut back in until the battery has spontaneously drifted down by 5%-10% of a full charge (which should take days with a normal, healthy battery).
You cannot over charge any Apple device.

My ipod touch 4g just updates today on itunes and the update caused more trouble than good. My ipod will no longer show me the battery percentage in the top right hand corner and also I am not allowed to drag other applications to the bottom panel.

My ipod touch 4g just updates today on itunes and the update caused more trouble than good for me. My ipod will no longer show me the battery percentage in the top right hand corner and I am not allowed to drag other applications to the bottom panel. Also my itunes doesn't allow "enable disk use" anymore. Can anyone help? My ipod now says that it's the 4.3.4 version

- Unjailbroken iPod never showed % battery. Just the icon.
- Unjailbroken iPod Touches never had a disk mode.
- What happens when you try to drag a wiggling app to a empty space in the bottom? Does it move and snap back?

My computer has been seen at Genius bar 6 times for freezing up, reloaded all original settings and even went to the apple shop where they replaced the battery and logic board. Still freezes after I try to reload iTunes stuff and app stuff from apple

my computer has been seen at Genius bar 6 times for freezing up, reloaded all original settings, all of their diagnostics, and they even sent it to the apple shop where they replaced the battery and logic board. Still freezes after I try to reload iTunes stuff and app stuff from apple, especially iPhoto which is seems to refuse to load and then begins freezing up all over again. Anyone else have this problem. Other than this, I have had absolutely no problems with this computer. Now, it's a file of junk.

Hi Ronald ...
Have you checked lately to see how much free space there is on the disk? Especially since iPhoto freezes at launch ...
Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space.
And make sure the OS X software is up to date.
Click the Apple  top left in your screen.
From the drop down menu click: Software Update
If you have anti virus software installed or are using third party Mac cleaning utiliites, that may be part and parcel of the your problems.

I was wondering why the iPhone 5 has the option for a battery percentage and the iPod touch 5g doesn't? I mean... they are almost both the same thing... just the iPod does not have the phone.

One likely reason is the % battery is not that accurate because of the smaller battery capacity in the iPod compared to iPhone and iPad. Users why use a % battery app post that the % reading changes a lot.

You can try recovery mode to see if you can revive the iPad.

Have you left the iPad charging for a couple of hours or so to be sure?

Make an appointment at the Genius Bar of an Apple store. If under warranty, as you say (the warranty is transferable) and not abused Apple will exchange it at no cost.

When will the color of the battery icon in the top bar will become red?

What is the percentage of battery life at which the color of the battery icon in the top bar will become red? 20% or 10%?

it is not a good idea to drain you macbook all the way down to see when it turns red. if it ever does - i've never seen mine red when it's down to 10%.
if you follow some of the threads here - some people who drained their battery all the way down to 0% can't turn their macbook back on.
From Apple's website:
Standard Maintenance
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her notebook on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month. Need a reminder? Add an event to your desktop’s iCal. When your battery no longer holds sufficient charge to meet your needs, you may choose to replace it. If your notebook came with a built-in battery, you should have the battery replaced only by an Apple Authorized Service Provider.

My ipod touch 4 generation wont charger or connect to my computer but it will charge using a wall charger. The battery was dead so I plugged it in to the Computer and it charged it enough to come on and now that it is on, it wont charger or register.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I just bought my first iphone. I am so disappointed in the battery life on the iphone5. Have the phones always been this way? Is there anything in the works to improve the battery life?

I just bought my first iphone. I am so disappointed in the battery life of the iphone 5. Is this the norm for iphones? Are they working on a fix to this problem? Almost wishing I had bought something else.

Without knowing what battery life you are seeing we can't determine if you have a problem. Have you compared your usage to the Technical Specifications?
Talk time: Up to 8 hours on 3G
Standby time: Up to 225 hours
Internet use: Up to 8 hours on 3G, up to 8 hours on LTE, up to 10 hours on Wi-Fi
Video playback: Up to 10 hours
Audio playback: Up to 40 hours
Under normal use, unless there's a problem with your phone, battery life is comparable to any other smart phone and better than some. If you've never owned a smart phone before you will be disappointed with the battery life on all smart phones. You should expect to charge any of them daily. It's a mistake to think of it as a phone at all; it's a very powerful pocket-sized computer that can also make phone calls.

My iPod says the battery is low, the apple symbol appears and then cycles back to low battery message?

My older iPod classic says when I dock it either with charger or hooked up to computer that the battery is low, the apple symbol appears, you can hear a whirring sound (hard drive coming on) then a clicking sound and then back to low battery message. Has been doing this for the last week.

Hey there Kevin,
It sounds like your iPod Classic is exhibiting some unexpected behaviour when you have it connected to your computer with the usb cable. I suggest the troubleshooting steps in the following article to help troubleshoot the device:
iPod classic Troubleshooting Assistant
http://www.apple.com/support/ipod/five_rs/classic/
Start by resetting the iPod, then retesting the issue.
Reset
To reset your iPod:
1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
2. Press and hold the Menu and Center (Select) buttons simultaneously until the Apple logo appears, about 6 to 10 seconds. You may need to repeat this step.
Tip:
If you are having difficulty resetting your iPod, set it on a flat surface. Make sure the finger pressing the Select button is not touching any part of the click wheel. Also make sure that you are pressing the Menu button toward the outside of the click wheel, and not near the center.
If the above steps did not work, try connecting iPod to a power adapter and plug the power adapter into an electrical outlet, or connect iPod to your computer. Make sure the computer is turned on and isn't set to go to sleep.
Thank you for using Apple Support Communities.
All the very best,
Sterling

On my iPhone 5, the battery symbol and percentage won't change, even while charging or during usage throughout the day. The battery is however charging and draining properly from what I can tell.

Has anyone had this issue or know of a fix?
Thanks

Try this
Restart iPhone: Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for phone to restart (no data will be lost).
Using the phone while charging doesn't create a problem.. I do it all the time
