edit : see 9th post of this thread , the guy ialexander has posted detailed steps . actually there is a feature in nothing to
charge upto 80 percent , but it only works at night time . there is a post where a dev replied with this answer
step 1 :-check mark the battery health option in settings (steadily overnight charging option)
step 2:- set an alarm anytime between 4am to 8am in the morning .
step 3:- plug in you phone after 9pm at night .
after following these steps the phone charges upto 80% slowly and will charge rest 20% when you are nearing to alarm time . I have followed these steps and it actually works . few things you will notice instantly that the phone does not show charging rapidly with the same fast charger if you are doing above steps . also it will steadily charge upto 80 % . and hold it there for like idk how long . (if you check the battery percentage in between it will assume you are not sleeping and charge will go till 100%. try it out ,
