Will this damage my iphone battery?

I accidentally charged my iphone for about 11 hours. I usually use a timer, but this time i forgot. My question is, will this damage my iphone battery? If so, what should i do to fix it?

In case you didn't know, that's not going to damage your battery.
It would have, if you were living some 10 years back. I used to keep my phone for charge at night and unplug in the morning.
IT IS NOT GOING TO DAMAGE IN ANY WAY!

You clearly don't know anything about batteries. You're an idiot if you think that damages it. Also, iPhone sucks.

Your iphone battery is safe now. Never repeat it again.
