iPhone: 'Ongoing Device Setup' in Battery after update
Should I be worried about “ongoing device setup” in battery settings of my iPhone after I just updated to IOS 26.4.1 an hour ago
What you are seeing is a good thing. No need to worry about a problem that does not exist. It may take a few more days to complete the background processes.
For what it's worth......Instagram is one of the biggest power hogs available.
