I disagree. I absolutely love the fact that I can just turn it off after office hours and throw it in a corner during holidays and weekends. Sure, it’s a bit cumbersome to take two phones with you, but it’s also cumbersome to take the laptop and everything with you all the time. Just put it in the same bag and you’re good. Good to note, my employer provides me with a phone, so I didn’t need to buy a second one. It also means that if I switch jobs, I just return the phone and still have my personal device.
But if it doesn’t work for you, by all means, don’t do it. For me the good outweighs the bad.
How does it damage the PN junction of the panel is open circuit or barely loaded? It doesn’t seem logical that this would damage the panel, but I’m open to being proven wrong.
There are all kinds of follow up questions to ask as well, but I think the main one is how big an effect are we talking?
