- try setcpu ( see thread http://www.androidtablets.net/forum/nook/5119-setcpu-settings-nookcolor.html ) - keep screen brightness down - you can try disabling telephony service - controversy exists if this is actually useful or not ( [SCRIPT] Remove Cell Standby Service (Super Battery Life!) - xda-developers )
I've found this really keeps the juice flowing. I mean the backlight on this thing could light up a football stadium. During the day I go 50-60% brightness, and in the dark, it's like 15-20%. I sometimes go 3 days between charges (10_ hours of active use ore more, and standby most of the time)
I agree. I set my brightness as 10% and it lasted 3 days with 10 hours of use. I also have the Cell Standby Service removed.
Thanks for acknowledging the controversy. I HATE superstitious reasoning. I DO IT all the time (knock on wood), but I hate it. Oh btw, once I saw that turning off the services "helped" I immediately followed suit. Call me a lemming. -Matt
After taking my nook to work yesterday I checked the battery stats. I had about 70% battery left. Of the 30% drained, it said 75% was used by the cell standby service. I haven't disabled it yet but I find it hard to believe that's not just a mistake. Can anyone shed a light on this? Sent from my Droid
The best explanation I've heard is that it's a catch-all state that includes a number of conditions, including radio state. I guess I'm convinced by the argument that turning off (or removing) phone and mms has no impact on battery life: Battery life analysis: myths and reality - xda-developers. But the good news is--superstitious or not--there's plenty of room for the believers and the skeptics! -Matt
OK, is this even physically possible: rooted my new Nook last night, and for fun, put it in standby (or sleep or whatever) at midnight. Battery reading at 91%. Woke up this morning, battery reading at 91%. Came home from work, still 91%. Admittedly, it hasn't been used in that time. But I couldn't believe my eyes. I even installed a battery widget as a second opinion, but same result. Just doesn't seem possible... -Matt
