There really is none, if you control the environment where someone is charging their phone while using it, it wouldn’t be hard to just point a hidden camera at the screen.

Or just offer free wi-fi and watch people’s traffic.

That assumes the camara always has a view and that there's no VPN or other layer protecting the traffic.

No, if all you want is detecting which one of 20 websites a user is browsing to, which you can by checking how much power it uses, you can definitely do that from traffic patterns even if the traffic flows through a vpn.

And this ‘leak’ assumes a user has his phone on a charger while it is already full, there is no guarantee it works.
