Auto brightness

golfinglenn · Jan 18, 2012

This is my first iPhone and I have brightness set to auto, but it never seems to change with light conditions. Even with auto set to on I can adjust brightness with the slider. Is this normal?

Mine does the exact same thing, not sure if it's normal though. 

Turn off auto brightness its useless plus its a battery drain.

That's kind of the whole point. If the ambient light changes, the display brightness changes along with it. If it's working correctly you won't notice a difference in the display brightness. It's changing, but it's all in the way the eye perceives it. If it wasn't changing then it would seem dimmer in bright light and brighter in dim light. And yes, it's normal to be able to adjust the brightness with the slider even with auto set to on. That just sets the relative brightness point.

Then it's not working properly as it should dim if I turn the lights out and it's not doing that. I have to manually dim the display in a dark environment as it is too bright.
