I sleep with my phone and look next to my head on a nightstand. I turn both of them into airplane mode before I go to bed, because I don't like the idea of transmitters next to my brain all night (so dubious the evidence may be of some difficulty).
The phone seems fine, but when I charge the clock overnight it seems to have updated e.g. temperature and weather conditions, in the morning, in bedside mode, it goes on and on and turns on Wi-Fi, etc.
Does anyone know if this is the case?
