Can you guys post how much brightness you have and if you have auto brightness on? Also how much battery life your getting.

I'm using auto brightness off and have it 50%

i have it on auto and its at like 1/10th of the bar. brightness would be a big player in battery life, but cellular connectivity and mail pushing i think are the biggest hogs.

I have it on auto all the time, never pay any attention to the specific brightness level, and the battery life is fine (although I don't use my iPhone all that much these days) :)

Great question.

I have my iPhones & Androids auto brightness turned off.

On my Galaxy's I have a widget on screen, that allows me to quickly & easily set the brightness manually depending on my environment. It's an easy & very effective way to maximize battery life.

On my iPhones, it's rather laborious, as I have to drill down through settings to change it. Nonetheless I do because the results are certainly worth it.

I set mine at 25%.

How much does this extend battery life? For me it's an increase of approximately 40%.

Auto bright off and fluctuate between 50-100% depending on the time of day/lighting.

On my first full charge I got 12 hours usage/1 day standby with it at around 70%. Combination of wifi and LTE connectivity.

I have auto brightness off and have it at about 40 percent. You get used to it and saves you tons in battery life IMO.

I have auto brightness on, and the bar is at 50%. Sometimes, the screen gets too bright, and I check slide bar and it's all the way up 100%! I may have to turn auto brightness off and just keep it at 50%..

No, not in a low light environment, for further clarification, I tend to adjust mine two or three times per day.

I have it at about 30% in the early morning. Around 25-35% during the day depending on if I'm in my office which is very low light, or out in the sun which demands it be increased.

After one adjusts to using a low setting it becomes very easy to read and greatly extends battery life. The display is a huge energy hog.

must not use your phone much or work very long :)
woke up at 7am and unplugged phone from charger (100%); did some casual texting/facebook/3 phone calls (3-8 mins each); watched 45 minutes of a movie during lunch; used Safari a few times...

...it's now 3:15pm and the battery is at 49%.

I've always had auto brightness set to on (which seems to be much more dynamic on iOS 6, fluctuating between 25% to 100%) and I still have lots of battery life by the end of day.
