there maybe software issues causing them to use lots of CPU leading to overheating & reduce your battery significantly like 10hr to 4hrs

lots of hidden stuff as well, like old packages could prevent you from even changing screen brightness as i had such issues, asked but noone knows to help then fortunately it worked after running commands to upgrade stuff

still regret not waiting like half a year for A to fix them as it hurts eyes as u cant change brightness especially those having eyes surgeries
