Couple of days ago I installed ios 18.2 beta update and now my iphone 15 pro drains battery and overheats like hell. It is difficult to touch. and as i plug out my charger, the battery drains very fast (30% to O% in 10 minutes with no literally no use) To note, my battery health is 100% with around 176 battery cycles and i always use original apple 20W charger and cable. I have even changed the charger to a new original apple 20W charger and the issue persists. I have reset it but still the same happens. so it is lying dead for 2 days because i cannot charge it because of extreme heating. I got it checked at apple authorised service center as mentioned on apple website, they said they would reinstall the software in warranty. today they said they said the issue persists after sofware reinstallation and saying it is hardware thing. What should i do??
