Is there a way discharge (MiBand4) it completely?

I had a really bad screw-up (all me i’m afraid). I had removed the menu on the watch from the app and one day i saw my band has disconnected my phone. Then i could no longer pair it and i cannot access the band settings as it only shows the time. It seemed like a good idea at the time since i hate how the screen sometimes activates and goes to Settings when i’m in the shower for instance. Hope you guys can help!
