The battery problem with 15.3.1 thru 15.4.1

Strange how so many people are having standby battery issues with iOS 15.3.1.
Barely used my M1 iPad Pro recently, not seeing any standby battery drain.

Ah, Low Power. Gotcha. As it happens, the phone was on 2% first thing in the morning (5% and dropping fast when I went to bed), so I switched to LP mode and it immediately dropped to 1% <shrug>.
Hopefully, it'll die sometime today, but who knows. At this point, the remaining charge value seems arbitrary.

It seems, the problematic ones is iPhone (possibly due to modem update). Also, people with no issues will unlikely post here.
I have newer devices -13 Pro Max - so my experience may not be relevant but battery life has been outstanding with no battery loss while in standby. Admittedly standby for me, without being connected to a charger, lasts no more than 4 hours. But when I have left a device off a charger overnight the battery percentage dropped at most 1-2% if that.
Still going strong on 1% (updated at 23:30 – ~21 hrs on 1%):

I woke up around 5:00, so went and took a look at the phone, which had, at last, run out of power \o/
I put it on charge, and here's the result four or so hours later:
The obvious issues here, besides the fact the phone was indicating it ran for 21 hrs on a 1% battery, are that the charging period is not marked, and the 100% recharge is not shown.

How has battery been for affected users on 15.0.x
Or 15.1.x
15.2.x?
Just now a problem with 15.3.1? What device also

15.2.x?

The level bar eventually appeared, though the charging period is absent and the Last Charged date/times has not been updated. Battery usage was fine through the day, but then the inexorable increase in charge usage overnight, when the phone is not touched, started up again.
Yes, but this is different. On your device there is something using power when the screen is off.
Hello I had the same problem and finally solved it, I hope. 
What I did is let my iPhone SE (1st gen) battery (84% health) drain to 1%. That was quick! Then I noticed it would stay at 1% without going dead, so I started Pokemon go at full display lightning and let it on. After 20 minutes, I opened Youtube and started watching crocodiles vs elephants, lions, etc. videos for 15 minutes and went back to Pokemon go, it was still going strong. I thought maybe there was a problem of some sort with a sensor and that 1% was not the real state of the battery.
Anyhow I decided I had given the battery enough chances to die and it wouldn't, so I pluggued the iPhone directling to the wall for charging. It took about 5 hours to go back to 100%. That was 2 days ago and since then I had 2 wonderful awakening to a 90% charged battery instead of 1 to 10% it used to be since upgrading to 15.3.1. Now I reactivated cellular data, locations services, notifications, etc. and everything's fine.
I have to say that when I noticed the first battery draining signs not long after updating to 15.3.1 I turned off Optimized battery charging. I wonder if this has something to do with the overnight drastic drains experienced lately.
Hope this help, it was after reading this thread that I decided to try letting my iPhone fully discharge and fully recharge it to the wall after.

Thanks. I have Optimised Battery Charging off, because (1) I don't charge daily, (2) I usually charge during the day. So it's not a feature that's designed for my charging pattern.
That said, it's probably worth me switching it on for a future test.
re: the 1% thing: Yes, I see the same thing – as shown above. Indeed, I've got it today. 5% when I woke up (3% in the grab just above) then 1% within minutes, and it's sat there at 1% all day. Here:

Have you tried the fully draining the battery and charging it back up a couple times like I mentioned before?
For what it's worth, Optmised battery charging was on by default before I went messing with it. I put it back before I started recharging my iPhone. From what I read of your previous comment (wednesday 4:33), you did the discharge-recharge thing by first having the battery die, if I'm not mistaking. Because it worked for me, I would repeat the process but with the battery at 1%, I read somewhere (this thread?) it's not good for it to let the battery die. At 1%, but give it a ressources beating before like I did to make sure it's the closest possible to the real 1%...
Have you tried using something like CoconutBattery to look at you battery percentage vs what iOS is telling you?
Maybe try causing the battery to die by playing a video game. When the phone shuts down, let it sit overnight and then charge it up to 100% and let it sit at 100% for 2 hours without using it.
I didn't mess with it, I switched it off while on 14.?? for the reasons stated. All was good on 14.??
I'll recharge it now. It's been on 1% for over ten hours with all sorts of usage.
No, I've not compared with CoconutBattery (or alternatives), but it's probably worth a try.
It’s normal for the battery percentage to disappear when it’s completely run out of battery and you let it charge without unlocking it. The question is, did you repeat the process another time?
