iPhone 11, iOS 15

I was at the apple store for an unrelated issues on 1/30. Updated from 15.2 to 15.3 that night. I went from 96% maximum capacity to now (3 days later) 87% maximum capacity and my phone dies in about 6 hours. Called back to support today and there is nothing that they can do

No battery will lose 9% of actual capacity overnight unless there's something really extreme such as being left at extremely high temperatures. What often happens is that one can have months (maybe even a year) where the battery health displayed by iOS is stuck at the same value and then it updates. It's not a real time battery capacity reading, but an estimate that eventually gets updated.
How long have you had the phone or at least when was the last time it had a new battery installed? That might give a better idea of whether or not 87% is typical or not.
Purchased the phone new from Apple 9/2020 so 1 year and 4 months ago. I’ve had 0 batter issues prior to Sunday when I updated from iOS 15.2 to 15.3. My phone would last 12+ hours, now lasts less than 6. The biggest change with my battery usage is that the battery is being eaten up when on standby
Truly dropping 9% in a week just doesn't happen. It's kind of a mystery when it updates. I will say that Apple diagnostics may not provide the same value. But you're saying 87% after 16 months? Sounds about right.
I can't say why your run time is so low, but that can happen for a short time after an update. Or there could be something with the update. Apple is pretty good about doing diagnostics on request. You can get that done at an Apple Store or by calling in.
They did run diagnostics on 1/30 and 2/2. Then last night, phone would not charge, went from 0% to 1% back and forth for 3 hours.
I have the same issue and I tried many times with the service support .. same answer they give
