Friends, last night I set a custom reference in Betterbatterystats and left my phone on my nightstand. When I woke up this morning battery was down from 23 percent to 4 percent. Deep sleep 89% (not bad, right?) . When i checked kernel wakelocks the major culprit was l2hscic which had kept my phone awake for over an hour. I have googled to no avail. The best i have found is that this is a wakelock relating to usb. But thats hardly enough info to fix it. Is anyone battling the same wakelock and has anyone found a fix yet? If so, please be kind enough to share. Thank you.
