Prevent Android phone battery charging above 80%

I see that there are apps in Play Store that, if you root your Android phone, can prevent battery from charging above a level e.g. 80% (so that you prolong it's life).
So I suppose there 's no way of doing this without rooting your phone?
Making something in app inventor?
(not with hardware, I know there is something called 'chargie')

Yes, you need root to modify the input_suspend file (on newer devices) responsible to stop charging at some point.
