Thank you for your help, but it does not fix anything.
Iām sorry, was a try ā¦ 
Came to the forum for the first time looking for help with this. Like others, I find that the adaptive brightness feature on my F6 tends towards not-nearly-bright-enough in most light environments, and does not seem to learn from the manual adjustments I make.
I found that when I turned it off, and just adjusted my brightness manually, battery life took a noticeable hit over the course of an average day. And that seemed to be regardless of how bright I set it. Anyone else experience that?
