Anyone else rooted their new nook simple touch and experience low battery?

PS, the NST should have it's own forum, I think this has been mentioned, right?

I took my rooted N2E to camping during the 7/4 break last Friday. On day one, I turned off WiFi (security concern), read for about an hour, and stowed the N2E. I was happily doing my camping activities the following days. On my trip back home today, I found the Nook's battery was completely drained when trying to turn it on to read again. Any one has similar experiences?

The rooting itself do not drain battery, it only give you administrator rights.
Perhaps you have installed some rogue app that drain your battery running the CPU at full speed when you think the nook is in standby but is not.
Install some task manager or app killer and check what is running on your nook.

I was thinking that too. Obviously rooting it wouldn't drain the battery, but I was thinking that maybe something like button savior was the culprit

I don't know now, though. The battery seems to be functioning normally. Just for while it was only lasting me a day. and it was on standby much of the time!

Thanks for the suggestions. I understand that rooting doesn't drain battery charge. I was running button savior, app killer, and ad blocker in the background. It should be one of these apps. I'll conduct some experiment to see which one is the culprit.

Rooting does install the adbd daemon as a running service. I'm running adb-wireless to turn the daemon on/off. I don't know what effect (if any) this has on battery, I wanted the ability to turn it off when using public wifi.

Does adb-wireless turn on/off adbd? I haven't checked. Which input port(s) (wifi, usb, etc) does adbd poll? Hard to imagine adbd draws a lot of battery. Any idea? Thanks!

Just checked. It seems that adb-wireless kills the previous adbd daemon and restarts a new one every time the toggle switch is pressed, regardless turning it on or off.
Off-topic for battery, but I installed this for security. I didn't want to leave the doors open every time I use public wifi.

I rooted my Nook Touch and installed ezPDF Reader, OfficeSuite, Opera mobile, etc...
I read a lot of PDF files with ezPDF reader - a lot of screen reflashes.
My batery lasts about a week. Is that normal?

The culprit seems to be ad blocker. I removed it from my N2E and the battery is now working as expected.

I'm getting about 2-4% loss a day without using it. Seems about right. I only have Opera mini installed right now in addition to google apps.

I have no extra Android apps installed. I have several GNU utilities installed (dropbear, ssh,scp,busybox,rsync), and am on my third week since I last plugged in. Wifi use has for been short intervals, a few times weekly. I read for an hour or so, daily.

My battery drain seems very bad too. About 15-20% per day. Only have adbwireless, advanced task killer and ezpdf reader installed.

Drain still remains after taking out ATK. Can't take out adbwireless if not I am unable to turn off my ADB when accessing wireless hotspots
