iPhone died overnight after iOS 27 update

iPhone just died overnight (no response to charging cable, any buttons, FDU reset button combo). The iOS 27 update was delayed because i do not plug my phone at night and last night i forgot and left cellular serivce on. Normally cellular service off because it drains my battery. IMO the iOS 27 update finally ran and killed my phone. Just replaced my iphone last January (last one failed into some type of cycle of power on screen and charging screen, while failing to charge, and also did not respond to button presses and combos).
