Update 19.30 - Battery runs out in a short time

With this update, my Fenix 5 X Plus loses almost 20% of battery in one day, after using only the GPS for 16 minutes and no PulsOx at night.
Without this update it lasted much longer. To lose a 20% it had to be at least 2 intense days of activity. I think there is a bug in the battery life.
Can you give me some advice?
Thank you
