Is it best to allow the battery in my iPad to discharge fully before charging or no.??
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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 (2.5W, 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.

Does allowing the Battery to drain to 0% depletes full charge capacity?
I bought a Macbook pro 17-in intel core 2 duo 2.4Ghz from the Phiippines on July 10, 2007 and brought it to Ireland couple of days after. Later, I upgraded to leopard 10.5.2 with 4 Gig memory. Auto updates have been installed since its first use. The only problem I encountered (except for some Safari quitting unexpedtedly) was in the battery.
Here is the record of my MBP battery use:
Battery information
Battery : MBP 17in Rechargeable Battery
Model: A1189 10.18V 68Wh
Serial: 6 _ _ _ _ _ DVYF1A
My Battery practice:
- I wait for 5% remaining charge before I plug the charger
- At several occasions I forgot to plug the charger before remaining charge goes to 0%
- I usually unplug the wall charger as soon as full charge is indicated.
- I sometimes leave the wall charger plugged for several hours after green light shows.
- I use my MBP for an average of 12 - 14 hours a day. At times I dont shut it down and just allow it to go to sleep mode.
- Calibrated about 10 times.
Record of Battery Life/Charging
Battery Cycle Life (based on istatpro) Full Charge Capacity (based on MBP)
1 100% No Record
62 100% 6492 mAh
66 100% 6484 mAh
100 100% 6484 mAh
300 98% 6213 mAh
301-317 95-99% 5850 - 6109 mAh
318 83% 5254 mAh
318 (at 3908mAh or 53% remaining charge MBP suddenly shuts down)
318 (MBP shuts down if wall charger is unplugged) Tried calibrating and resetting SMC but did not work.
I then checked if my MBP is still covered by the one-year warranty despite more than 300 battery cycles, no bulges present at apple website https://selfsolve.apple.com/GetWarranty.do (here you have to enter your MBP serial number)
I brought my MBP for check up here in Dublin, Ireland and indeed the problem was the battery. They replaced my battery with a new one without cost.
Thanks Apple my new battery now has a Battery Health of 100% with the following initial cycle records:
Battery Cycle Full Charge Capacity
1 (33% remaining charge as soon as I received it) 6810 mAh
1 (I then used the remaining charge up to 1%) 6726 mAh
1 (full charged) 6810 mAh
1 (full charged) I let it rest for few hours then checked 6879 mAh
2 (full charged) 6879 mAh
3 (full charged) 6876 mAh
4 (full charged) 6830 mAh
5 (full charged) 6845 mAh
5 (full charged) I let it rest for 1 hour then checked 6868 mAh
6 (3% remaining charge) 6829 mAh
I forgot to plug the charger (battery drained to 0%) 6492 mAh
Notice the sudden drop of full charge capacity in cycle 6? How do I recover the lost charge capacity? Does letting the battery drain to 0% depletes its full charge capacity?The short answer is that yes, completely draining the battery has a slight negative impact on full charge capacity. The full charge capacity does fluctuate a bit over time, but the general trend is downward no matter what you do - there's a continuous chemical reaction occurring in the battery, with a finite life.
However, I note that you state +I wait for 5% remaining charge before I plug the charger+; if you are doing this because that is what you need to do, i.e. you do most of your work away from a power source, fine. But, if you are doing that because you believe that's best for your battery, that is incorrect. The 'old' NiCd batteries performed best with full discharge and full charge. The 'newer' Li-based batteries do not have this requirement, and in fact perform better over time when used frequently but 'lightly', avoiding full discharges (except for the occasional battery calibration, which allows the OS to more accurately determine the time to charge and discharge).

Since I have upgraded from 7.1 then the power consumption increased slightly unbelievable. I have new batteries in my iphone 5 and when I had at ios 7 so was consumption that allows the battery envelope in two days and with ios 7.1 so is it only 12 hours before I need to recharge the battery.
Wrote a little wrong the first time!

Mi iphone4 doesnt allow the battery charge
Hello, mi iphone4 doesnt allow the battery to charge, how can I know if with a new baterry it will work??

After the inital die/recharge of my Iphone 5, is it necessary to, once again, allow the battery to completely die before charging? Or, can I just recharge it when the battery gets low?
You can recharge your phone whenever you want. The lithium ion battery (not just apples) have a certin amount of charge cycles like any other lithium battery. A charge cycle is a complete 0%-100%. So sticking it on the charger everytime at night doesn't count as a charge cycle. If your batter is at 80% then you charge it to 100% that is 20% of a charge cycle. Its a little confusing, but I learned it with doing a lot of asking and research. Don't worry, just charge your phone when you need to and you'll be fine.
Its recommended to do a full charge from 0%-100% once a month to calibrate the battery meter. -
The battery on our IPad is not charging??
the battery on our IPad is not charging, what to do??
Could be the charger, cable or iPad. Plug the USB cable into your computer. It may say "Not Charging", however, it is charging slowly and will verify that the cable is good.
Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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).

MD513AE/A iPad Wi-Fi-16GB White - Model A 1458
I have purchase this from Dubai, UAE, some 2 years back.
I am NOT able to switch it on; when connected to power supply, the battery icon comes in but no signs of charging.
After some times the ‘Apple’ icon comes in. Tried simultaneous operation of Sleep and Power buttons, but of no use.
Sometimes a picture of cable and ITunes comes in; but not able to connect to
P C as there is no battery charge.Hi madhu254,

The battery of my iPad four drawn very fast after update to iOS 8.1 and the sensitivity of my iPad decrease until I cannot swipe it and is very lag >< please fix it immediately
Hello alicelan,
After reviewing your post, I have located an article that can help with device errors. You may want to consider restoring your device to factory settings to resolve the issues you've described:
Use iTunes to restore your iOS device to factory settings
Restoring iOS software deletes all your data and content from your device, including songs, videos, contacts, photos, and calendar info.
Before you restore your device
Make sure you’re using the latest version of iTunes.
Use iTunes to back up your device. Transfer and sync any additional content to your computer.
Turn off Find My iPhone in Settings > iCloud on your device to disable Activation Lock.
Restore your iOS device
Connect your iOS device to your computer using the cable that came with it.
Select your iPhone, iPad, or iPod touch when it appears in iTunes. In the Summary panel, click Restore.
Click Restore again to confirm that you want to restore your device to factory settings and delete all data and content. iTunes will download the iOS software file and restore your iOS device.
After your iOS device is restored to factory settings, it will restart. Once it does, you’ll see the "Slide to set up” welcome screen. Follow the steps in the iOS Setup Assistant. You can set up your device as new or using a previous backup. If your iOS device has cellular service, it will activate after you restore.
Learn more
If you get an error message, find out how to fix most update and restore errors.
If your iOS device with cellular service doesn’t activate after restoring, find out how to fix activation issues.
If your iOS device restarts repeatedly or isn’t responding, for example if you see a stopped progress bar or no progress bar, put the device into recovery mode and restore it again.
Thank you for contributing to Apple Support Communities.

My iPod touch 4G will not charge. I charged it and when I got it off charge it was really hot but showed it was fully charge then when I turned it on again the battery was dead. Now it won't charge. Please help thanks!
Try the standard fixes to rule out a software problem:
- Reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory settings/new iPod
if still problem that indicates a hardware problem and an appointment at the genius Bar of an Apple store is in order.
I suspect you have a hardware problem. -
My iPod was updating to iOS 6 and i shut it off during the update because it was taking too long and now my screen in baby blue i've tried to drain the battery but when i plugged it in to charge the blue screen came back on.I dont know what to do
Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order. -

new out of box , unable to switch on is there a problem with the battery as i thopugh it should be partly charged.
Plug it in for 15 minutes. If it doesn't come on hold the HOME button (the round one) and the SLEEP button (the one on the top) at the same time until an Apple logo appears (about 10 seconds). If nothing appears on the screen after 30 seconds you have a dead phone; take it back for exchange.

The new software update - iOS 7.0.2 is killing the battery in my iPad. I have searched online and taken the recommended measures to decrease battery use, but within hours my iPad is completely dead. It would take days to kill the battery before this update. I am very frustrated. Can I undo this update???
This typically happens when some apps on the phone were interrupted by the upgrade. When it comes back up the app tries to resume and can not. You have to find and kill that app(s).
Do you have an Exchange account?
That is usually the culprit. Go into Settings and turn off all of the toggles for the Exchange account. Then reset the phone (hold the Sleep/Wake and Home buttons and don’t let go until the screen goes dark and the Apple logo appears). When the phone powers back on, turn the toggles back on.
Do the same for all mail accounts if you don't have Exchange or that doesn't resolve the issue.
If it is not Exchange/Mail then it could be another app(s).
With iOS 7 you can control what apps run in the background. Go to Settings > General > Background App Refresh. This will list all of the apps that can run in background. Turn them all off and restart. If this fixes the problem turn on a few at a time until you find the one causing the trouble.
