Well the author sort of neglected to state whether the device was charging at the time, which makes a difference. No doubt it wasn’t always charging but it would be fair to clarify when it was. The OS has some activities like checking for updates that it is more likely to do if tethered to power. Also some of the activity can be related to measures that actually save power. For example, before attempting to do a heavy download of data provided by apps that implement background data downloading, it makes sense to first check the quality of the network connection. I’d suggest everyone just chill and realize there can be good reasons for things, not just bad reasons. And consider the possibility that Apple is not stupid when it comes to power management.
