After upgrade from A12 to A13 I observe almost x2 overnight batter drain. Here're stats from BBS + AccuBattery (not overnight, just 2 hours of doing nothing, but overnight data is the same).
This is AccuBattery, on A12 off-screen consumption was ~35mA/h, on the same set of applications - I've had a straight upgrade without data wipe from A12 to A13.
In BBS, you can see that the whole time was spent in Doze Idle, and nothing in Deep Sleep.
And here're in BBS we see some suspects - something is holding PowerManagerService's locks. Unfortunately, it doesn't provide further details - who and why holds it.
PS: in settings, adaptive brightness = off, smart screen = off, always on panel = off, lift to check = off, screen saver = off.
