Georges asked me to send him additional battery information indicated in the app.
"Go to the settings of your Smart Lock> Manage Smart Lock> Battery. In addition to that, there is a hidden feature on this screen. Click 7 times on the text“ Nuki Smart Lock will automatically… "
I had charged the battery in the meantime for 30 minutes.
When I put the battery back in the Nuki to get the information, the app told me 100% charge.
Additional battery information did not reveal any issues.
Geroges told me that the battery arrives with around 75% charge, I’m skeptical because the first charge lasted several hours (the LED stops flashing).
Today, after several openings and closings, the battery still shows 100%, which seems strange.
I wait a few days to see if the battery voltage drops sharply like the first time.
