iPhone 15 Pro Max randomly shutting off after recent iOS update

I've had my iPhone 15 Pro Max since January of this year and have had no issues with the phone. Battery life currently says it's at 94 and I've been able to go my whole 9+ hour workday while listening to music and return home with 20-40 percent battery left after starting from 80 percent. Then all of a sudden after an update nearly 1 month ago as of this post, my battery's percentage jumps all over the place and the phone will randomly shut off. I originally had issues with the phone's speaker lowering randomly as well but have since seemed to fix that problem after going through several hard resets. Yet, the battery issue persists. I've tried every tip I've seen online so far and even went as far as wiping my esim during a factory reset and I've just did a recovery wipe and update through iTunes with my pc and it's still shutting off on me. I can't afford a new phone and don't have the time to drive over 2 hours to my nearest apple store just on a thin chance that they can do something different. Has anyone else had this issue and been able to get it solved?

Thank you for taking the time to reply. I ran the diagnostics, and everything came back looking good. So, I can't understand why my phone is still acting up. I am up to date on the current version since the one before this current one is when all the problems started to occur so I was hoping the update would fix it. But unfortunately, it only fixed my speaker problem. I haven't downloaded any new apps and I don't have any Meta apps that were suggested to be a possible cause for issues on others' phones due to all their constant updates. I'm almost at the point of just giving up and buying a cheaper phone at this point that will allow me to make calls and read texts without shutting off on me every couple of minutes. But again, thank you for the help!
