I have a Nookcolor. I basically use it at home alot. I read on it, occasionally surf the web and facebook and I play Words With Friends and read Devotionals, etc...off and on during the day. Doing all this of course while connected to WiFi. I notice that I have been having to charge my battery almost daily if I dont want it to die on me while Im reading at night. I know that turning off the Wifi will save battery but I hate to have to connect it every time I want to do something that requires Wifi..are there any other ways to reserve the battery time?
Turning wifi on and off is easy. Just tap the lower right hand corner (that shows the wifi and battery) and you bring up the quick settings menu. Tap the wifi to turn it on or off. To get rid of the menu, just tap anywhere outside of the quick menu. Your previously-connected wifi settings quickly connect, even with security passwords, etc.
On the other hand, yes, with active usage you may need to charge the nook color daily. Besides turning off wifi when not needed, turning the brightness down may help you get longer life from the device.
I find the biggest consumer of battery, by far, is the screen. With screen brightness set to about 25%, I see roughly a 10% battery drop per hour. With the screen off, this drops to 1%. I have found that leaving wifi on if I am connected to a wifi network doesn't make much difference. If you are not connected, the device will spend a lot of unnecessary battery upping the radio and trying to locate an access point.
So reallly, the more you play with it, the less total time you'll see. I just make a point of charging it overnight when I can. I'm happy with it, and it's much better than any other device I've owned.
I leave wifi on all the time except if I take my NC out of the house (which is rare - I usually take my N2E with me when going out). But, I also agree with the others about just charging it every night. Frequent charges like that will not harm a Lithium polymer battery, nor will leaving it plugged in all night. With a max. rated reading time of only about 8 hours, it is simply not going to last much more than a day of heavy-to-moderate use anyway. Just the nature of LED backlit color LCD devices, in my experience.
I tend to treat it just like my cell phone - always plug them in at night so they are fully charged and ready to go the next day. I almost never actually pay any attention to where the battery meter actually is.
Oh, and I also keep my screen backlight set pretty low. I find I only need to set the slider up a very little bit from the far left and I can read just fine and minimize the power used by the LEDs.
I've noticed a huge difference in battery life since the upgrade. I think the battery is still discharging when the Nook is in sleep mode. I was actually down to 14% battery charge left today. I've had my Nook for over a year and never had this happen before. This afternoon I checked the battery and it was at about 45%. I turned the screen brightness down all the way, made sure wifi was turned off and put it to sleep. I came back a couple of hours later and it was down to 14%.
Something bad in that upgrade, I just know it.

I think you've got something else going on. If it were just the update that started zapping power, then it should have affected lots of people, which would have caused an uprising. I haven't noticed any difference since the update on my NC
Odd timing, though, for you. Maybe there's an app you use that for whatever reason doesn't get along w/ 1.4? I dunno...
I have a question to add to the discussion for anyone who knows. I know that the Nook will update itself when in sleep mode, so if you leave wifi turned on but Mook in sleep mode, leave the house w/ your Nook, is it searching for a wifi connection all that time while in sleep mode, or does it only try that once you wake it up?
I think screen brightness is the biggest key to battery life. I tend to keep mine at 30-50%. I usually just leave wifi turned on except at work, which has a few hoops you have to jump through to connect, and it gets annoying dealing with the popup box about connecting throughout the day. I've been impressed with the battery life on my NC so far, and mine was bought in September as a refurb. I don't actually time it, but I usually only have to plug it in every other or every third day. My smartphone has a much shorter life and isn't really used very much--certainly not as much as my Nook during the day.
