I didn’t say having the phone within reach was unhealthy. What you *do* with the phone and *when* you do it can be unhealthy. For me, it’s my only phone, my calendar, and my alarm clock. I know how to (not) use it when in bed, so it’s quite alright.
I’m not sure my use case is intuitively niche. Do you have data showing that people don’t use their phone as an alarm/phone, in a silent manner so as not to disturb a partner?
Are there other solutions? Sure. I’ve solved mine with an existing device and a $30 magnetic charger.
