unless there is a smudge on the glass/screen protector that sits on top of the light sensor
Agreed, it can also go out of calibration at any time, it's random and never has been reliable. Always has and always will be unreliable and chew up battery.

Perhaps for some. It almost always worked reliably and without battery issues across multiple iOS devices I've dealt with, and it looks like there are various others who have posted here and other threads that have been using it without any real issues.
That's basically the point as to your comment--while what you are saying can certainly apply to some people (as essentially is the case when it comes to a lot of different issues), by far, it certainly doesn't seem like there's some sort of a longstanding/ongoing issue with auto-brightness, either with how it works or with some type of extensive battery usage associated with it.
Not true sorry.
Auto brightness may have been unreliable back in iOS 3.x but it's been solid since iOS 5.0
I leave Auto-brightness, Bluetooth, Wifi, Background Refresh and location services on ALL the time and I get 10-12 hours of battery usage per day.
People need to let go of these outdated concepts of turning things off. Things are not like they used to be.
I've heard god arguments from both camps.
Auto brightness is definitely more convenient. But it can need calibration and with the ios 7 control panel it sometimes is because the brightness slider gets touched.
Manual gives you more control and can help with battery life if you keep the level low but it is a pain having to change the brightness when walking from room to room

I agree with you about the manual control. Although you could save battery by keeping it at 50% or so brightness it stinks having to constantly adjust it when you're moving in and out of differently lighted areas.
I have to say I am very impressed by iOS 7's auto-brightness compared to prior versions. It's just always dead on for me. I never feel like it's not bright enough or too bright.
I keep auto-brightness on with my iPhone, since I use it on the go and I need different brightness for different light conditions.
I use manual brightness on my iPad, since I use it mostly indoor and I need very small (if any) variations. I just lower brightness at night, in a dark room.
