Mobile Phone Disconnect everytime after night

Hello everyone,

i got a Problem with may Epix2. Every night my Phone disconnect with my smartwatch. Its weared because many of the times its half Disconnected. It means if i get a message on my mobile phone my smartwatch get it too. But if i want to luse the search function with the watch, to find my mobile phone it doesnst work (waiting for the phone)  or the weather also doesnt work no temperature is displayed.

The way to fix this for the day ist to start the connect app, than the devices reconnect, but this is really annoying. I cant believe thats normal? I want a permanent connection.

My watch notet my normal Sleeptimes. I dont found any function there to configure the connections in the sleeptime mode. I also looked for energy saving mode options but dont found something to help.

Sorry for my bad english, but i hope you understand everything. :)
