I have it off but generally does having it off help your battery life and does the same apply for the ipad as well? As it was mentioned in the ipad forum.
 
Yes 100%

The phone is obviously having to power a certain function to auto correct the brightness

Switching this off the phone doesn't have to use any power to control anything

So yes I would say it would use up more power, how much is a grey area

It's not going to be that much imo
 
Once and for all...does having auto brightness off help battery life?

If I have auto brightness turned off and have my brightness at 25% even when I am outdoors...

While you have auto brightness turned on and the auto brightness bumps the brightness to 80% while outdoors...

Which one of us is going to have longer battery life?

But it also dims it down too, so it works both ways

It depends on if he goes outside / takes his phone out while outside) or anywhere that causes his screen to brighten.

The brightness of the screen determines current drawn on the battery (battery life).
 
It depends

Exactly my point ;)

OP asked a silly question that really just depends on how he, personally, uses his device and if he is in a bright environment or not. No one else can answer this for him...

It's not a silly question at all when quite a few have asked the same thing.

When inside and using your phone inside...not outside it is a fair question. Which is why it was brought up by others.
 
Turning on auto-brightness reduces your battery life compared to when you put it on the minimum with auto-brightness off.

Right?
