As I was preparing to wrap up the night, I noticed when I checked my Moto X4 that the BOINC on the status bar said to plug in the phone. The time was 7 hours ago (per the system) though.. I never had this issue where after been put on/taken off the charger that it didn't update.
I tapped it and then it briefly said to plug it in as it opened up and then everything updated.
I checked the log and it starts at the time when I tapped open BOINC so I can't verify it was actually running beforehand. Note I don't swipe BOINC off the Apps quick list (at the bottom).
Also, I have seen discontinuities between other actual apps and what's on the status bar so this may not be all BOINC's fault. For example: Weather Underground status use to be linked with the actual app screen although they changed it and now the app has to update itself when opened.
