Browse source 
* settings page located in Settings -> Battery
* soc-based step charger, jeita thermal charger switch (also done something in kernel)
* add a mode for user always connected with chagrging cable to limit battery around 40% - 60%
* add a switch for user to limit max charge at around 80%
