I think most iDevices now will have a relay to stop charging the battery when it's full. Some might say that it could deteriorates the battery life but the I think that it's normal. You can't expect a 1 year old battery to be performing as good as a new one.

Apple Explains New iPad's Continued Charging Beyond 100% Battery Level
Tuesday March 27, 2012 12:06 pm PDT by Eric Slivka
Among the many topics related to charging, battery, and heat issues with the new iPad, observers have noted that the device continues to charge for up to an hour after the point at which the iPad reports a charge level of 100%.


AllThingsD has now spoken with Apple's Michael Tchao about the phenomenon, with Tchao noting that it is simply an effect of the same trickle charging feature that has always been included in iOS devices.

So, here’s how things work: Apple does in fact display the iPad (and iPhone and iPod Touch) as 100 percent charged just before a device reaches a completely charged state. At that point, it will continue charging to 100 percent, then discharge a bit and charge back up to 100 percent, repeating that process until the device is unplugged.

Doing so allows devices to maintain an optimum charge, Apple VP Michael Tchao told AllThingsD today.

“That circuitry is designed so you can keep your device plugged in as long as you would like,” Tchao said. “It’s a great feature that’s always been in iOS.”

Tchao notes that users can expect 10-hour battery life on the new iPad regardless of when in that trickle charge/discharge cycle they unplug their device, and that Apple intentionally displays the battery level at 100% throughout that cycle so as to not confuse consumers who might otherwise think their device is not completing charging correctly.

You'll never know what could happen, right ? Are 100% sure or just 99.9999% sure ?
Power surges could blew everything up... Better safe than sorry

me too having this problem using charger from mini but stuck at 87%,89%, but use iphone 5 charger can fully charge 100%

Anyone made a complaint to Apple and manage to get change to a new charger as our charger is faulty and can only charge until 89-91% and not 100%? I think Apple should change for free.the charger.

It's not the charger faulty just the device is build that way or should I say all lithium polymer cell is like that let your ipad drain to 0 or dead and re-charge to full approx 12hrs to calibrate the battery

Just wondering, If the feature is with I device, why charging it with iPhone charger is able to charge till 100%?

Mine terbalik. I have to use my iPad Mini charger then can charge till 100%. Before this I use my iPhone 5 charger it stuck at 91%. huhu...

I own an iPad Mini !!!
