Is battery life affected much by rooting? I'm not see any drastic reduction so far although I did drain it to about 18% with all the downloading I've been doing! :)

I agree, the rooting process itself should have no effect. The difference, if any, would be a matter of the CM7 ROM power usage vs. the stock ROM power usage. I recall something about sleep mode problems in CM7 making it a little worse, but that might have already been fixed. I'm pretty sure JP will be able to set me straight on that point.:)

Latest nightlies of cm7 fixed the sleep issue though rankly it wasnt much of problem if you charge it before bedtime - mine can last a day and a half or longer in standby

Mine will last for days in deep sleep, {after installing Nook Tweaks (after CM-7.1.0-RC1-encore)}.
I check mail now and then then; back to sleep.
I'm two days in and still showing 86%.

With full internet use I have an average of 10-12% per hour.At 1200mhz usually.
Deep sleep doesnt consume anything.Whole night without using it and next day is around 1% down.

Good responses. As others have said rooting by itself won't make a difference. What will make a difference is using OC kernels and changing processor governing settings. Battery life with CM7 7.0.3 Stable and non deep sleep versions is about the same as stock or rooted. Maybe a little less but you are getting a performance bump from 800MHz to at least 925MHz. Deep sleep extends standby life condsiderably while use time stays about the same.

Generally speaking you can get about 8hrs of moderate use and about 1-2 days standby without deepsleep and several days standby with deep sleep.

I downloaded Nook Tweeks but it's useless. Says it's not compatible and "a newer version of Dalingrins kernal is required" I'm running CM7 (7.0.3) off an SD card.

Then flash Dalingrins Kernal and try again. Nook Tweaks gives you nice control of Processor - and ability to boost sound volume as well.

[Kernel][Stock1.2][Already included in CM7] Dalingrin's OC kernel [6/30/11] - xda-developers

I think the newer Nightly CM7 ROM's have the Dalingrin kernal as a part of the builds - but don't hold me to it.

7.1rc1 n136 and above incorporate the overclock kernel. N150 added the fast boot (under 30 seconds to boot). These nightlies are very good and improve the overall operation of the nook.

Cm7.1rc1 is the latest release. The nightly builds of 7.1 have many new features not available in 7.0.3. The overclock kernel was included in nightly 136 (I think that was right) and the new fast boot was included in nghtly 150 and above.

I have yet to see a thirty second boot time. Mine's more like eighty seconds, which ain't bad either.
Quad tested at 2285
