What happens when you overcharge your iPhone?

Nothing just stays at 100% charged

Nothing.

Apple devices run on Lithium-Ion batteries that are programmed to cut their charging voltage and trickle charge after reaching a 100% charge.

Nothing happens

You can't overcharge an iPhone.

You can never overcharge an iPhone because apple is very intelligent if you have ever noticed on an iPhone the little lightning bolt in the battery changes to a plug, thats the iPhone telling the charger its done charging and if the battery falls below 100% while plugged in the iPhone tells the charger to come back on and bring the iPhone back to a 100% where the process will start all over again!
