A Pixel Tablet that will not last is being asked to do two jobs on one 27 Wh battery, per Wikipedia: run as a portable tablet and sit on its Charging Speaker Dock as a smart display. Google says the battery can last up to 12 hours streaming video when it is not charging, so a tablet well short of a working day is the one to look at. Google's tablet article gives the order: restrict the apps using the most battery, turn on Adaptive Battery and Battery Saver, shorten the screen timeout, and if the tablet lives on the dock, use Battery protection, a feature Google built to prolong the battery on the dock.
