[Nexus One Android Development] Docmjldds:
I have been using a newer Seidio 1600mAh battery. I noticed today that I seemed to be stuck at 96% battery. Spare Parts showed Battery Full and the display still said charging. When plugged into USB so that I could run adb shell cat /proc/kmsg I confirmed this as shown here:

<6>[ 275.572052] batt: 96%, 4133 mV, -1 mA (-2 avg), 33.6 C, 1451 mAh

<6>[ 576.336761] batt: 96%, 4133 mV, -6 mA (-5 avg), 33.2 C, 1451 mAh

SetCPU was set for on demand and profiles enabled. I wanted to have full capability in my car when plugged in, so I had enabled full CPU during charging, but was using 245/245 for sleep setting. Seems that this kills ability to charge. I had not changed settings yet at this point. I powered off, pulled battery. Reinserted battery, wiped batt states in recovery, rebooted and still saw no charging. AC would say it was charging, but stats stayed the same.

I had charged up the stock battery back in Feb. and put it away. Placed it in phone, wiped batt stats in recovery and booted up. Battery had 59% from first week in Feb. :D

Same problem under USB, where it would say charging on lock screen, but appeared to not to actually be charging. I had tried changing sleep profile to CPU setting of 650 to see if that made any difference. Nope. I then eliminated profiles and immediately charging would now work, but I have an occasional Voltage error cannot get high enough, as shown in the following readout.

Currently at 84% battery charge now as i am writing this with that occasional error, using the stock 1400 battery. After charging to 100% I will try the 1600 replacement after marker battery again, with stock SetCPU settings.

But getting more of those voltage errors.

My charge rate appears to be working fine, since i started at 59% 2 hours ago and it's up to 84% now. Battery temps also dropping which is good.

Main question is SetCPU settings. Seems that sleep mode and using min max 245 is NOT a good idea. Thoughts please on all of this. Using the 4/19 Kernel, BTW.
