Battery problems

[Danny poleg]

SP9 PRO
The watch is not on the wrist at night and yet there are nights when the battery level drops drastically (not every night - that’s why I ask)
We reviewed all the options - back lighting - heart rate monitoring - sleep monitoring and more
We performed a light reset by pressing the top button
I would appreciate further suggestions for treatment and solution

@Danny-poleg unusual. Another test you could try is to have the watch in airplane mode (maybe it is connecting and reconnecting to the phone?).

@Danny-poleg what do you mean by drastically? Have you tried drying battery to 0 and then to 100%?
