Before you go "doy, of course the battery drain is more with higher brightness".
What I did was I left my phone untouched for 30 minutes on medium brightness and put my phone on idle and my battery didn't move. I put my brightness to high and backed out and put my phone on idle right away, left for 30 minutes and it went down 4 %. So i changed it back to medium and left it for 30 minutes or more while i ate dinner, drained nothing.
Why would high brightness cause drain when the phone is on idle??
Odd.
