hi @Sakib

charging a phone from about 40٪ takes about an hour if you use fast charging. when you charge a phone past 100%, the battery starts to die and it may heat up. so what i would recommend would be do it before you go to sleep and as soon as it gets to 100%, take it off.

But i heard that nothing will happened the phone or battery if i charged it overnight.
