    I have reduced my screen brightness to 40 and still have almost 40% battery life left at the end of the day after a typical day of use. Prior to this, I had my brightness level set at 100 and could not get through the day without charging.

    The difference between brightness level 40 and 100 is minimal.

    Backlight brightness = 10
    Backlight timeout = 10 seconds

    I do the same thing LL HUGH J said. Works like a charm. Also don't let apps sit in the background. My phone is now half full still after a work day. Perfect for me.

    Is it also true that if you disable automatically dim backlight, that saves battery life too?

    Swear I read that somewhere... For now I do have it enabled, as I've always found it a nice feature of the blackberry

    +1

    I've always done the same thing, and great battery life on Verizon. I had the backight timeout set for 30 seconds for 2 days, but it was really eating up the battery. Switched back to 10 seconds and it's a lot better.

    I don't know anyone does 40-100 brightness. It kills my eyes. Even 10 is quite bright. You won't even notice it.

    That is a possibility, as that may disable the proximity (ambient light) sensor...

    The battery isnt the issue, its the carriers networks. Myself being with Rogers, is H+ and currently the H+ network isnt what it should be. I tried this with my 9900 i turned off the network for about 3 hours and used it to play some games and the battery only dropped 12%. thats nothing after 3 hours of use. 9930's have a different radio so they will have different performance than a 9900. bottom line is until our carriers dont make the network stronger and more widespread the battery life will not be ad good as it was on previous phones. i hope rim makes a feature to turn off h+, like in the manage networks pannel, have one for 2g+3g only.

    I set mine at 10. The lowest. Plenty bright. I also keep blurtooth wifi and gps off unless needed. And I go into all apps and set the update intervals to the very most seldom I can tolerate or turn it off.

    I have mine at 50%, 45sec auto dim. I read a lot, and I can't read a full page in 10 seconds. I wish RIM was a little more sophisticated when auto diming instead of just using a timer.

    I used to laugh at iPhone users with their retina display barely lit up.
