Fell asleep while charging my iPhone?

I never charge anything overnight. I have a particular way of charging things. Last night, I was charging my iPhone 5. I started charging it around 9.It was 11:30ish at night and my phone was at 98%. I wanted to wait until it got to 100% before I unplugged it. Howeverm I fell asleep before I unplugged it! This morning I woke up at 7 because I remembered that it was still charging! Is it okay that it was charging for that long? :/ Is it possible to overcharge an iPhone battery?!

It will be fine.

Its fine! You can charge it overnight NOTHING WILL HAPPEN! Promise.

I overcharge my iPod and my friend overcharges her iPod and our electronics work fine. It's no big deal, it's a favor at the most since the batteries die so quickly.

I don't think you could overcharge a phone battery, I think it messes up the battery and it lasts less, i diid this all the time but I stopped doing it

It's a problem. You should immediately drop the phone. Drop it from about 4 feet. It will reset the lithium ion batteries. Then stick it under the sun. Do that for 2 hours exactly. That will expand the battery and retract it.
