nightly reboot by RTC
the last 2 nights, i wake up and my phone has rebooted (it appears this doesn't happen if it's in a power plug), but since power is still very high, it's not that the battery is dead... last night it was still 94% charged, and i haven't charged it yet and it's still working...
the /var/log/systemboot.log
(which gives the reasons for booting) says the following:
x-no-time-stamp Startup: preinit ignored on pwr_on_by_RTC
20140206_030555 Startup: pwr_on_status=pwr_on_by_RTC
x-no-time-stamp Startup: preinit ignored on pwr_on_by_RTC
20140207_002854 Startup: pwr_on_status=pwr_on_by_RTC
i should note that i don't have any alarms and uptime does look like it rebooted at that time.
looking at that logfile, i never had this before, i only had 2 software reboots (the upgrades) and a few hardware reboots when i was testing with wifi somewhere in januari
