I rooted my Nook Color in January.  Got a bad card from a unstrusting Amazon seller and ending up losing out.  I decided to buy another card in April when I got a gift card.  This one is working fine.

But, man, do the apps eat up my battery time.  I was able to get 7-8 hours off my NC before I rooted it.  Some days it seems all I get is 3 or 4.  I have to charge it every day.

I do turn off the WiFi when I can.  That saves a little.  I've always had the screen dimmed since I can't take the bright screen.

Are there any other things I can do to get more use out of each charge...besides not using it?

Okay, speaking in general about tablets, you may be able to turn down the "brightness" under preferences.  This is often set automatically really high, in a demo mode for display, rather than on a dimmer mode for home usage.  Then Airplane mode, which turns off the wifi.

You can go to settings, applications, running, and see what is running in the background. From there, you can close them.

In addition you can get Advanced Task Killer from the google play store. With one tap you can see what is running, and close the ones you want. However it might not get them all.

There are also some battery usage monitors. I've heard people recommend GSAM Battery Monitor. I use Battery HD.

If I recall, that was one of the reasons I decided to get rid of the Nook Color and replace it. To me the NC never seem to run as well on the n2a card, but of course was completely useless for our needs without the card.

You should STRONGLY consider getting a Nook HD (currently $129). You will be amazed at the difference. *unless* you really need something(s) from the Amazon app store. You can't put that on the Nook HD (well you can, but it takes more work than I feel like doing as of now).

Mine certainly doesn't.  When I'm on the Nook side, it connects to my home Wifi with no problem at all.  On the Android side, it takes multiple tries to get it to connect, if I even can.  I find I'm not using the Android side much unless I want to play Angry Birds Star Wars.

If they drop the Nook HD under $100, I'll probably get one.  Otherwise, I'll stick with what I've got.  I do find battery life isn't as good when I've got it on the Android side.

Same here. $99 would be an awesome deal, now that it has google play. And for reading, personally I find the HD+ WAY too big for me to read on. I don't like reading on my Fire HD 7" either, the bezel on that thing is huge. Colleen's 2nd Gen Fire is pretty hefty. I hate the screen on my other daughter's Lenovo. So I'd love to have a Nook HD to try out. 

11.1 oz on the Nook HD is lighter than any of the tablets we have. And the screen is 1440 x 900, also better than any of the 7" tablets here, including my Fire HD. The only reason I didn't get the Nook HD for my girls for Christmas, was the lack of apps.

I have been hanging onto a BN gift card my daughter got, I think it's for $10. Maybe when my DH is out of town me and the girls will go down to the BN store and check out the Nook HD for ourselves. Maybe I can talk her into selling her piece of crap Lenovo and getting that instead.

I just talked to my daughter and she is more than willing to make the trade. Yay! So I will definitely be getting her a Nook HD soon.

I love my Nook HD.  I've downloaded Google play and Amazon Kindle app.  Works like a charm.  And really, if Google Play doesn't have it, do you really need it?

I read for 5 hours on my Nook HD yesterday and still had a 60% charge on it this morning.

Oh that's right, you can put the kindle reading app on it. I forgot. That's good, because Nicole has her own Amazon account with a bunch of kids books (they were freebies) so I am glad she will still be able to access them. 

Sherri did you get white or dark?\

Never mind, I saw you got white. Duh!

Thanks for the tips.  I do have the screen dim as a necessity.  These devices are just too bright for me.  I'll look for the apps to kill stuff in the background.  I have most notifications set to off on apps.

The first one I got was obviously defective. When I returned it the seller said it never arrived.  My mistake for using stamps and not printing a label (we were out of ink and I was impatient).  I got a bad vibe from the company with communications right after I bought and I suspect it was just some guy working from his house.

The second card was from a different company and they were very responsive to early questions.  I'm pleased with this one.  I bought one for my Mom's Nook Tablet and I can see a big difference in how much play time she gets from hers.  It's just more efficient altogether.

I use mine primarily from the card.  I rarely switch to the NC startup anymore.  I never read on my NC (I can't read for any length of time on this type of screen).  Since I've got the Nook first edition, I don't need anything else to read on.  I did have the Kindle app but I deleted it since I don't really like reading on my NC.
