Situation: I was using firefox with 1 tab of YouTube with video on 720p from the period of 22:00 to 23:00 night that is 1 hour, the battery percentage at the start was 91% and dropped to 64% and no apps were used in the background nor did open just firefox and nothing else, I get anxious of these battery issues everytime I see battery percentage dropping quickly unnecessarily cause I know the experience wasn’t like this at the start it used at least give me 5 hours with these usage now not even 2.5 hours
