Note: if you insert batteries, you must immediately configure the device to connect to your Wi-Fi.
If, for some reason, you can't connect the device to your Wi-Fi and want to do so tomorrow, remove the batteries as they will be much more charged while you set up the connection.
If you do a factory reset, you have to reconfigure the connection with your Wi-Fi because everything is deleted.
