Battery

I use iphones since 2008 and I've always charged them overnight, everynight.

Battery life won't be affected, since it's measured in cycles.

1 charging cycle = from 0 to 100%

1/2 charging cycle = from 50 to 100%

1/4 charging cycle = from 75 to 100%

Iphones batteries lifesfan is around 500 cycles.

The olny precaution is, if possbile: do not let the battery level go down below 20%

Excellent response from ProustGiulio.

And here is very much the same response in another thread:

Is it ok to charge my iPhone all night - Apple Community

Iphones have a cool feature that it knows that it is close to 100 percent charged it charges it slower so that it won't overwork/ overcharge the battery. I personally try not to just because you can charge it before you go to bed, but nothing bad will happen if it is plugged in all night

Leaving your iPhone plugged in is fine. It cannot be overcharged.

i think this will decrease the battery life.

Thanks. I would enjoy joining you for a good cup of coffee.

Enjoy your day as well.
