Do anybody knows when we charge our iPhone more than the required time ... I mean when 100% level is achieved .... Do there is any damage to the phone for overcharging? Do there is any auto-cut function in the phone to protect it from overcharging?

I've been told it won't over charge. I charge mine over night every night and always have.

You can't overcharge it. It's perfectly fine to keep it connected to a charger after it reaches 100%. I keep mine on a charger all night.

You can't overcharge an iPhone, there are built in components that will prevent that, I charge mine all night every night, no issues.

IIRC, once the device is fully charged, it goes into a small drain/charge cycle to keep from just sitting there trying to charge once capacity is reached.
That's why at times users can unplug after overnite and be at less than 100 percent...

I charge mine every night and nothing too horrible has happened, however sometimes when I unplug my phone from charging, it goes down to 95% or something around there. Anyone know why that is? Is it because I use my phone while it's hooked up to the charger when it was already at 100%?

You cannot overcharge an Apple iPhone battery. The battery charging technology draws power from the charger as needed, it is not pushed to the device. Once at 100% it stops requesting anything from the charger and will then begin to discharge a small amount. Once it gets back down to approximately 98%, it will call for charging again. This cycle will repeat over and over again. I have had every iPhone since the first and three iPads and at the end of my day, I place the device on the charger when I go to bed. I have never had a problem and never noticed an appreciable degredation in my battery performance.

Apple does recommend that you don't leave them plugged in all the time however.

Thanks Talon for that good piece of information. Now I can charge my mobile freely overnight to which I was reluctant before. :)
