    One other thing I did... I set the screen time-out to be an hour. I did this originally because the 1 minute time out was annoying, but I noticed that it seemed to help the battery life. I guess leaving it on required less power than it going up and down and up and down all day long. Try it and see if it helps you. I'm curious to find out if it's just a placebo for me..

    looking for a good one...
    I used Rico's suggested profiles and I'm still testing but I think they gave at least 2 hours more..!! I'm happy!

    You need ADB installed allready on your PC, and make sure it can recognize your Nook properly.

    Click on the link 'download removal' in the very first post of that thread. (It will take you to megaupload to get a zip file)

    Extract everything in that file

    Hook up your nook to your pc

    click on the .bat file in the extracted folder

    Your nook should reboot

    That's it.

    Thanks for clarification. Can you explain ADB? I've seen the term, but never looked into it.

    This wiki can explain it much better than I can...and it will give you instructions on its installation.

    Does anybody have a good way to do a run down test? Maybe running a timer and playing a movie on continuous loop so that we can get true comparissons between various settings?

    I know this thread is old, but I have a related question. Would a quick fix be to leave my NC in airplane mode 24/7? I see a lot of my battery usage since root is going toward cell standby. I'm not technical enough yet to mess with this ADB stuff. Airplane mode doesn't appear to affect my WiFi, will it affect anything else if I just leave airplane mode on? And will it in fact improve my battery life?

    Airplane mode? I didn't realize there was an airplane mode on the NC. Other than turning off the wifi.

    Via elixir widget, I can toggle on airplane mode. It then turns off WiFi, but I can then toggle WiFi back on and stay in airplane mode. Not sure if its helping the battery though, because cell standby still shows up under battery usage.

    Thanks. I just browsed through that thread. Today I noticed that my NC took longer to charge back up than it had the past few days. Then again, I used it down to about 30%. I will now be shutting wifi off when not needed and see how that improves things.

    Hey...I'm a bit new around androidforums.net, but I wanted to add (if I'm not late adding it, lol) that you can remove phone.apk and the telephony apk (sorry, offhand I forget the exact filename) uising Root Explorer...I simply renamed their file extensions to .bak and the system thinks they are no longer there...and should I need to undo this- I would just rename them back to .apk... :)

    I haven't taken time to read the entire thread yet either...but I did notice that cell standby was taking about 43% of my battery usage...so I'll keep you all informed as to how removing those 2 apk's worked for me...

    I did get a chance to read it... seems most people are now of the mind that this has NO effect on our nook since there's no actual cell/telephony hardware. So don't bother with it.
