    So now that my Incredible is rooted, I wanted to ask what can I do to improve the battery life. I have already removed most of the bloat-ware. Thanks for any input.

    Well....

    1) Do a search. I am not saying this with a RTFM tone, but with a "I do not know everything and you will find small tweaks that may help that you would otherwise not know about" tone.

    2) Undervolted kernel. I like hydra, but I also use AOSP so I am out of the loop as to what the best UV sense kernel is. This will make the biggest difference.

    3) different ROMS. Again, I have no good advice, but there is a difference between ROMS, and a search will help you find one that both satisfies your battery needs and that you like the function of.

    there are many more, but I forget most of them as I have just resigned to having a UV kernel and charging as often as possible, as CM6.1 has worse battery life than stock, if you can believe that.

    if you want sense i heard a lot of talk about skyraider3.5 and lou's #8 kernel but i found redemptive revolution and ziggy's bfs to be the best for my phone. on standby i was losing 1 or 2% per hour after 12 hours my phone finally hit 90%. that was the best i ever did so far but i am always looking for a way to squeeze out battery life. good luck

    I'm using the stock ROM and Lou's #8 kernal, battery life is good.
    Monday was a fairly light use day for me, streamed 1 30-minute old radio show, sent a few texts, talked on the phone for about 15 minutes and played about 30 minutes of solitaire. That night when I went to bed I realized I'd forgotten to plug in my phone, but didn't care enough to get up and do it. Tuesday at noon after some more light use, off the charger for 31 hours at that point, it was still showing a 65% charge (1800 battery).

    There are a lot of things that you can do, some that don't require root access, that will improve battery life without affecting performance. I'll detail some things here, and mark them as (ROOT) if root access is needed.

    1. Disable 3G always on: From the home screen, hit menu, settings, wireless and networks. Find this option and disable it. This means that your 3G data connection will be turned off unless requested by an app that needs to sync, or unless you need to use data for any reason. This is a huge battery saver. NOTE: Only available on Sense-based ROMs

    2. Use wifi when at home; If you have a wifi connection at home, keep it turned on all the time. Wifi uses very little battery when connected but idle. When your phone needs to sync, wifi uses considerably less battery than 3G. NOTE: Using option 1 or 2 will give you a substantial boost to battery life, but using both in conjunction will only give youa small boost over using just one. In other words, don't expect a double-boost from using both.

    3. SetCPU (ROOT); This requires its own guide. Click the link for the free download from the developer, or buy it for $1.99 as a donation off the Marketplace. When used properly, it can underclock your CPU under certain conditions, which will save you some battery life. The most popular is the screen off profile, which causes your CPU to be locked at the minimum speed when the screen is off. This gives a substantial boost to battery life.

    When it comes to kernels, you'll often here of terms like "HAVS" and "Smartass." If you have HAVS, it's best to not use SetCPU. If you have both of these, then DO NOT use SetCPU.

    Smartass as a governor causes the CPU to top out at 384mhz when the screen is off. HAVS causes the CPU to automatically under-volt based on the clock speed, giving you a double boost to battery life over just underclocking. SetCPU can mess with this functionality. In my experience, using SetCPU with a kernel that has HAVS causes sluggish response and performance while negatively impacting battery life.
