Default [Q] Cell standby using battery

Since rooting my Nook touch I have had it on for 6 days. I checked the battery usage and it tells me that "cell standby" is using 87% of the battery and "phone idle" is using 12%.

Anyone ideas on how to disable those functions?

Perhaps airplane mode would disable those, but I don't know how to enter airplane mode. I do have nook color tools installed.


Thanks

Sent from my CM7.1 NookColor

I actually ended up unrooting precisely due to this... I'm researching and trying to figure out a way to root w/o installing things that consider the nook as a phone... A custom rom is being produced on this thread.... Hopefully it will be a lot more close to a reader than a phone: http://forum.xda-developers.com/show....php?t=1208024

You can delete /system/app/phone.apk and telephonyprovider.apk,then phone idle will disappear.

I'm wondering, Phone.apk and TelephonyProvider.apk are already installed in an unrooted nook, aren't they ?

BTW, there is a script here for the Nook Color, it should work for the Nook 2.

But I don't know if it will have a real effect on battery life or not ...

I just changed the file extensions, as mentioned in the "[script] remove cell service" thread, also seems to work.

IMO, both "cell standby" and "phone idle" and just about all actions that nook does when it is in sleep mode. Removing these apk's however helps just a bit because there are none useless phone apps running in background, but there still will be "cell standby" thing in battery stats.
