Automatically limit (stop) battery charging at a given percentage

Device : Moto X Play ( Rooted, Stock, Android 6.0.1, msm8916 Board, XT1562) ## Why do I want to limit charging ? ( Let's leave out whether my reasons are valid or not and accept that I **want** to, if you disagree with my reasons) To improve the longevity of battery , I wish to limit charging when it reaches 90%, as explained here https://android.stackexchange.com/q/156526/131553 ## Is it possible? Yes, at least on my previous device Honor 6, as brought out here https://android.stackexchange.com/q/92413/131553 , with two different ways of doing it I have tried unsuccessfully to identify the file responsible in which changing values would limit charging ## I am looking for the system file responsible for stopping charging, with it's true path (without symlinks) (as I saw on on my previous device, locating the path of file was a big challenge after identifying it) ----------
