Do you take steps to optimize your Android battery life?

As you know, I carry a LOT of phones around every day and thus have become accustomed to charging my devices every night, for the most part. I also carry a charged battery for my primary devices (Nokia N900, HTC EVO 4G, and Google Nexus One) just in case I have some heavy needs (like a camera session, podcast downloads, or streaming video period) and am not close to a charger or portable power pack. Google Android devices have a LOT of things running and connecting that you may not even know much about, but I just read an excellent article over on Just Another Mobile Monday that will help you wade through all of the happenings on your Android device to gain some battery life.

After reading the article, I went to my HTC EVO 4G to check on display brightness and saw that it was on auto-brightness. I went ahead and selected a level at about 25% because that is more than adequate for 90% of the time I use it. However, I break most of these guidelines because I figure I have devices with 3G (4G too), GPS, great cameras, and more so I am going to use them to their fullest and just charge up regularly or carry extra batteries.

Do you take action to manage your battery life or do you just go for it and charge up regularly?
