is ios 26.6 draining anyone else’s battery?

Basically my iphone has been overheating, draining battery extremely fast (like 1-2% per minute), and barely charging at all when plugged in. I took my phone to apple today and my battery health is at 90% and they did diagnostics and said nothing was wrong. At the end the employee mentioned that it might be because i have a beta version of ios and now thinking about it this is about when this problem started is whe around when i updated to ios 26.6. Is anyone else having similar problems?
