I disabled the auto backlight. I then manually adjust it depending on my needs . I spent the whole day at airports going from Pittsburgh to Denver to see the Steelers beat the Broncos tonight and I still had 25 % battery after multiple calls, dozens of texts and surfing the web for many hours. I also used handscent for sms . The autobacklight is set very bright . I am trying to find a good app to add as a widget to quickly manually adjust the brightness . I found one but it did it in too big of steps. Any ideas?
