Thank you for your bug report. That's more likely to be a kernel issue
than a desktop one though, gnome-power-manager is only including a
frontend to see battery stats nowadays. Is there any chance you could
try with a xenial kernel to see if that works better?
Otherwise the desktop component handling screen settings is unity-
settings-daemon but that codebase didn't change much in recent cycles...
note that level changing when disc/connecting from/to a/c is an old
issue though it could depends of the driver.
Unassigning the desktop team since that doesn't seem like an high
priority issue nor a desktop regression.

Title:
Brightness resets to full when on/off battery
Status in gnome-power-manager package in Ubuntu:
Incomplete
Bug description:
In yakkety, when my ThinkPad X250 goes on or off battery, the screen
is reset to full brightness. Xenial and before did not have this
problem. I have not found any other instances which trigger this (lid
close, etc).
