I´m asking this because my iPhone is suggesting me to do it, but I thought it was the other way: the phone constantly calculate ambient light so this process use more battery.
Thank you.
iPhone 5s, iOS 9.2.1, null

My experience with Auto brightness is that it keeps the screen too bright. What my colleagues and I have found (and this holds true across a large number of makes and models of phones and tablets) is that you'll save battery life if you turn off Auto brightness and turn the screen brightness down to as low as you can use comfortably. That's almost invariably dimmer than the auto brightness would set it to.
Personally, I don't think auto brightness on iPhones works all that well.
Hi
I found turning off Apps Refresh makes battery last another 2/3 hours between charges.
Cheers

An article in the NY Times last Thursday (2/25) about extending battery life on smartphones suggested leaving auto-brightness enabled on iPhones.

Perhaps I will revisit the issue. However, I know if I turn on auto-brightness, if it does anything, it turns it up. Now, perhaps I'm unusual in how low I keep my brightness. If so, my advice wouldn't help most people.
Auto Brightness can be calibrated. Turn A. B. Off, go into a very dark room like a closet, manually adjust the brightness to the minimum desired and then turn A. B. back On. It will remember this low setting but even then it may be too bright for some as it adjusts up. Worth a try perhaps...
Thanks for the suggestion. Should i ever find a closet in my house tidy enough to walk into and shut the door, I may give this a try. 😉
LOL... 😉
Turning on Auto-Brightness does save battery life?
