Why is there so much data usage after midnight

I was checking my data usage on my phone see attached. Why is there so much data usage after midnight til 1am? And not over wifi.

If you used data during the day, PM will report it only twice a day so it might look like you used it in one batch.

OR, if you leave your phone On with data On some apps might be doing some maintenance and use your data. Do not leave data on during night...

The system updates the data usage once or twice a day, one of them overnight, o those times are not accurate, it’s the aggregate data usage aine the last update
