    I'm sure this has been asked a billion times before, but does having auto-brightness on save battery life? I usually keep my brightness below 50%. Like 40-45%. I've had auto-brightness on since day one, and I don't really mind it, but if it doesn't save battery life, I think I wanna turn it off.

    Thank you!

    It is recommended by Apple, in terms of extending battery life.

    Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.​

    From doing some research on the net and from Apple, screen brightness is probably the the top battery drainer.

    The auto brightness keeps my brightness low so if you want to save battery id suggest you keep it on. I find myself turning up my brightness though because the auto brightness usually keeps it pretty dim

    I find that auto brightness uses your brightness setting as a max. Mine is plenty bright and I have it set to the default or 50%.

    I've been using my iPhone for atleast 5 hours a day. Is it detrimental to the screen to have the brightness at 100%? Is it possible to burn the pixels?

    I keep mine at 100% (as I have with all my phones) and there's no problem. If I'm running low on battery, brightness is the first thing I cut back, but besides that...

    i keep mine at about 40% with auto brightness. I tried using it at 50% but it was too bright for me. I dont like my screens really bright. Even on my macbook i never go past 50%.
