Your syslog looks fine, and your behaviour is indeed super weird. Were you able to still turn it on after reproducing such issue and powering it off? Wonder if the battery status would still be the same after a reboot. There is nothing special at our userspace, it's basically getting the battery data from the kernel directly. So it's either a kernel bug, or a battery firmware bug, hard to tell from now (I was only able to reproduce this bug once, and it seems people are also having similar issues with the Android version of it https://www.youtube.com/watch?v=YAmdswKehQ4 ). > Should I file a bug issue or attach this to an existing one? Please open a bug against https://launchpad.net/canonical-devices-system-image, adding your syslog in there as well.
