Just a couple of days ago my Iphone updated.
It took it a really long time to do it.
After that, the battery on the Iphone 6, which I've only had for a couple of months, started running down in a day. It had really lasted a long time before that. I was actually thinking that I wondered if they'd update it again soon, to fix whatever they'd done.
Well, today it updated again.
I don't know that they're related.
I do know that I really wish Apple would be more content to just let these things exist in a steady state without monkeying with them all the time.
