NOTES: I have dualboot setup on my nook with stock 1.2 installed on parts 9/10. Installation steps: Formatted /system(ext2), /data(ext2) and /cache, Installed stock 1.0.1 then updated to 1.2, setup dualboot partitions, moved 1.2 to dual boot parts, formatted /system(ext4), /data(ext4) and /cache, then restored CM from backup. I often switch between CM7 and 1.2.

CM 7.0.3 Stable.
EDIT + NOTES: Battery finally died at 4%. I went near or below 3,000mv when it happened.
I had 13% with 3606mv. Voltage started free falling once I hit under 5% battery, I watched it go from around 3400 to 3060 all within the 4% range, right before it died, was trying to screencap when it died on me. I was a little over 12 hours off charger, I took it off at 96%-ish.
It seems 3000 to 3050mv is that cutoff point.
Well I'll be damned. It is for sure a calibration issue. Somebody Googled these batteries and read that they could not go below 3050 mv safely. I got pbd repeatedly just a few minutes ago at 20%... and 3000 mv.
Put the charger in and juiced it up a couple percent (showed 3600mv with charger in), unplugged, and let it run down again. Shutoff at 20% and 3000mv. I was able to replicate this multiple times. I already know that my 100% of scale is always right around 4200mv so it seems as if the 0% of scale is out of alignment.
How to recal the 0%?
Yep, my pbd happened at ~3-3.2V. Seeing as some people are reporting only ~10%-20% at ~3.6V, seems like our batteries were SEVERELY depleted. I hope they were not damaged because of that :/
I'm letting it run down now. Will post my u-boot, MLO et al. when/if it reaches 3.3V.
I think it would help if people starting finding our their voltages when or near their battery dies. Seems to be a pattern developing.
Here ya go, I got down to 4%, went to plug it in, and it shut down right before I got there. I got a screenshot of the 3041mV I believe. When my Nook comes back on (showing the charge screen right now) I will upload the shots.
however, let's discuss this over a beer sometime - which is the independent variable here? I think the first plot shows the precipitous voltage drop-off in a more graphic fashion... But, as always, your wish is my command
BTW - MATLAB won't let me (simply) reverse the x-axis order...
By now, we’re all quite familiar with Tasker, the personal automation app that seems to be able to … more
