The battery problem with 15.3.1 thru 15.4.1

Similar experience with my iPhone 11, where standby battery looks quite good (1-2% overnight), however browsing safari easily made the back phone warm. This rarely happened back in 14.8.1.
So, at last, there has been a change in behaviour:
The overnight gaps are a mystery, but at least the battery isn't draining. The only change I made was to delete a Reminder at 22:00 – there are now zero active Reminders. The result, so far, is 28% drain after ~36 hours, which is similar to what I was getting on the final iOS 14. That said, I currently have most things turned off: all Location process, Mobile Data, and so on.

One thing that is odd though are the white gaps on the graph. Unless you have a special view, I don't recall ever seeing the gaps.
If it were me, I would contact Apple Care to get the device or battery replaced.
Try 15.4. If it's related it might be fixed with the update. Keep us posted!
I also had a serious battery problem.
I fully drained it two times and charged it overnight.
Seemed ok after the procedure.
Now downloading 15.4, we will see.

Now on 15.4. After pondering over this problem for a few days, and examining the problems others are having, I had an idea, a hypothesis, and this is the result. I changed something, and for the first time in almost two months, I got normal overnight battery drain. Let's see what happens over the next 24 hours.

I wouldn't expect it to. In the example you quote, which was ages ago in the scheme of things, I was trying to isolate the possible cause of the battery drain. Mobile data was just one of those things.
I will do. I want to see if it holds up first. Then I'll need to reverse it and see if the old behaviour returns.
So far, so good. About 20% in 24 hours, which is what I was getting on iOS14.
That is still a pretty heavy battery drain. I see maybe 5% at most, many times at 0% over night drain. Have you tried doing a fresh install of iOS and setup as a new device. I hope you resolve the issue because it is not fun figuring out how to solve these issues.
A issue I had since iOS 12 was the case where whenever I connected my phone to CarPlay, a random music song would start playing. It drove me nuts because it would have the headhunt turn on and play the music through the car system. It would startle me at times because the volume level was where it was last and if I had forgot to lower the volume, I would get this loud blast of music. I spent iOS 12, iOS 13, and iOS 14 trying to find a solution. With iOS 15 I still had that issue. But I happen chanced upon a Apple senior advisor who put me on hold, come back on the phone with me and told me to try deleting the Music app off my phone and reinstall a new version from the iOS App Store. And it resolved the issue. I would have never thought the culprit was the Music app. I thought it was iOS that was the issue. I have to tell what a relief it was for me to find a solution to the issue.
And here we are 24 hours later… and it's all gone to hell:
Anyway, I'm done with this. Instead of charging every 4 days with iOS14, I'll have to charge every 2 days with iOS15. That's ridiculous for a device I barely use. By comparison, my 6½ year-old iPad Air ("stuck" on iOS12) retains charge for weeks (currently on 82%, last charged 15 March – obvs. it's not doing phone things).
I doubt I'll be buying another Apple phone. Apple hardware is great, and their software used to be, but it seems to be in terminal decline. I can justify paying the Apple tax when hardware and software are working well together, but it makes no sense when they don't. Apple is a closed system, a walled garden, it has no excuse for not being able to make everything work. And when something is broken, they should fix it and be proud of that.

This, I think, is the core problem: the lack of diagnostics tools, or pretty much any way to hunt down root causes. I understand Apple's reluctance to open the barn doors, so to speak, but there is a middle ground. There is clearly far more complexity in Apple's ecosystem that a decade ago. I don't believe they have adapted to that at all well – if at all – from the customer's perspective.
I used to feel kind of cradled in Apple's system – the whole: it just works thing – but now it feels rather hostile.
You might want to consider setting up your device as new and see how the battery life is as a new device. See how it is overnight as a new device. Just a thought.
If you have the same bad battery drain setup as new, you talk to Apple about either getting the battery replaced or your phone swapped out. Apple would want you to try setting up your phone ad a new device before they would consider swapping it out.
Update:
Thanks to this post, I did a Network Reset (Settings/General/Transfer or Reset iPhone/Reset/Reset Network Settings), and this is the result:
So, two days + six hours (54 hours) and 56% used. That's close to 1%/hr, which is far the best I've achieved on iOS 15.3 or 15.4, though it's still some way off iOS14. For ref: Mobile Data is on, and so are Location Services, although Find My and System Customisation are off, because they permanently light-up the location status bar icon.
