[Samsung Galaxy Nexus] drtrmiller:
Unplugged at 100% and went from that to 90% in less than an hour. Here's my BBS dump.

At one point in time in a previous build of the kernel, I was getting spectacular battery life with about 50+ hours standby. Now I'm getting around 15 with normal usage.

PREVIOUSLY, when I was getting good battery life, I was getting plenty of "deep sleep" in CPU Spy.

Below, my screen was off from the time I unplugged, a little less than an hour, and ZERO deep sleep. Lots of "kernel wakelocks." Not sure how to interpret.

Any assistance would be greatly appreciated.

Edit: I did some research and discovered another Samsung device, albeit with a different Android OS and different kernel, and the discovery indicated an issue with battery drain and kernel wakelocks when rebooting with Wi-Fi turned on. Just rebooted with Wi-Fi and BT off, and phone appears to sleep now. We'll see how long it lasts, or if that was even the issue.
