My watch hasn’t recalibrated with the new battery. Even a couple of weeks later I still get premature low battery - it can take hours for the final 10% to run out after the first 90% only took 9 hours. I left it off the charger for multiple days after installation and yet I could still quickly wake it up by pressing the crown to see the time reported with red numbers, so I don’t think it fully ran out.

Is there a way to force calibration? A Google search didn’t yield anything useful in the first several pages of results.
