I would not let the phone discharge to as low as 5% , drops quickly once in single figures. I would advise not letting it drop below 15% anyway to maximise battery life. see one article here: https://charbycharge.com/how-often-should-i-charge-my-phone-to-prolong-the-battery-life/
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
