And yet... it does seem unusual that such a large number of people have a hardware issue at the same time, yes? Even if it's not the majority of users, it is a large number. I mention that because this has echoes of the recent battery issue that came up with another recent iOS upgrade, which somehow killed the batteries for 6 and 6s users.
There too, there were a few forum post folks saying things like, "Well, sorry you've got a problem but not everybody is having it so you're in the minority and need to suck it up." Or the equally frustrating, "Do a full restore on the phone, that will fix it." I was one of those getting those replies, even from Apple, which told me to do the full restore.
And like so many others, that didn't work.
And then, minority issue that it was, it still triggered the Apple Battery Replacement program, for which it turned out I was eligible. They replaced the battery and since then the phone has worked fine. But the point is clear. It issue enough then that the rising outcry reached Apple and stirred them to do something to fix it (by the way, I love Apple and I'm sure they want to do right by customers... it's just a critical mass issue).
This too seems like an issue that's got a rising number of people pushing for a solution. That solution could very well be written into 10.3.3. Here's hoping. Or it could be that these folks on this forum who are suffering the rapid battery drain are people who somehow escaped the issue last time around, and who could get this fixed with an extension of the Battery Replacement Program from before.
To that end, I've been asking people here -- those that still have the issue -- whether they are having it after a recent battery replacement. I haven't gotten a clear answer from anybody yet. Until I do, I'm not upgrading to 10.3.2. Which *****, because I hate that the security flaws it would address now have to remain open.
