It wouldn’t shock me. A lot of improvements to 14 are reeling in idle usage. In fact, that’s a big focus on the last 3 or 4 Android versions, and something Android is doing to catch up to iOS.

It seems better for battery life to do batching and budgeting of background activities as much as possible, instead of continuous, unregulated usage.

I think the one thing I miss is that Android used to have idle background battery usage estimates, so that you knew which apps were killing your battery in the background. It’s not quite as easy to figure that out anymore, but maybe something new will come along to help out with that.
