Charging Battery

[Bazile]

I was reading that it wasn't a good idea to constantly charging the battery in your mobile to 100 % , because it reduces the life of the battery faster
You should charge it up to about 80 %

Is there any setting on mobile phones that allows you to stop the battery charging at any particular point ?
