Post ICS battery issue

Wifi or mobile data on all day except for two hours in the cinema. But I can't wait for the battery to go flat as I need my beauty sleep!

Brightness was set to 31%. I usually had that set to auto with Gingerbread. I do have custom power saving set to kick in at 30% battery remaining. Otherwise nothing special. Emails are collected every 30 minutes and I have five imap accounts and gmail set up. I also run Facebook.

PS I used 505MB wifi and 2MB mobile data yesterday.
 
Nice, did it perform like that straight from the update or did you run it down a few times?

I got two batteries that im in the process of running down a few times each to see if that resets them to perform how they were before the update where I got long life out of it with heavy use.
 
I ran it flat the day before (the same day I got the ICS update) but even then despite quite heavy use the battery consumption was not abnormal at roughly 6% per hour.

I know everyone has their own opinion regarding screen brightness but on every smartphone I've ever had I always have mine set at around 75%. I've tested the phone with it set much lower and noticed very little difference in battery life. On older phones screens were a lot more battery hungry and there definitely was a noticeable difference (as in several hours difference). But now with screens using a lot less power the difference really is minimal. I just don't see the point of having it set very low when it makes little difference to battery life. And please people, I'm not criticising people who use low brightness settings, I'm merely making an observation.

Are other people really getting that much more out of their phone with a very low brightness setting? When I tested my Note I noticed less than an hour's difference in battery life with the brightness down at around 30% compared to 75%.
 
OLED screens consume little power if the display is largely dark no matter the brightness setting because there is no backlight. But if the screen displays a lot of bright areas then the consumption goes up. It's a bit like plasma v.s. LCD. So I can understand that screen brightness settings might have less of an effect overall on power consumption.
