**First of all, thank you very much for the charging control feature - it is awesome to be able to set the threshold like on my Tesla, although I would have preferred for it to go down to 50%.
My question is regarding what is happening when the threshold is reached, and the phone is not charging while plugged in.
I suspect that it starts running from battery because I have had the phone plugged in all morning, it reached 70%, and now it is down to 69%.
I think the nicest implementation would be if the phone started running from the charger, or charging with equal current to the one consumed, for example the same way that a Tesla acts while plugged in - it attempts to charge/discharge the battery as little as possible.**
