I do lots of testing of apps in real phones, not emulators.
The thing is that the phones must be connected to the PC all day. Because of this, phones battery get swollen and I have to buy phones regularly.
Do you know any android phone which can be connected and on all day all week without getting swollen after a time?
Must be real phones, emulators are descarted.
That’s behavioral recommendations, not a setting in the phone.
He wouldn’t need the setting if he’s leaving the phone plugged in all the time.
But that’s why they need the setting, because they are leaving it plugged in all the time.
It’s not a setting because it works automatically. You don’t need a switch to toggle this behaviour. It’s always on.
