Thanks! I could be wrong on this but looking at the log it seems like you receive messages which then may stay showing on your watch with a flashing messages widget for half an hour or more.
There was another thread on this recently where @WizardStan tracked the battery use down to the messages widget: https://forum.espruino.com/conversations/398746/
You could try uninstalling it (or disabling flashing in the messages settings page)? The widget isn't vital, but if it's flashing every second for several hours a day on average, that would definitely hit your battery life.
