Battery drain after iOS 14.7 update

I am using iPhone 7 Plus. Everything was working perfectly till I updated it to 14.7 last night and I keep seeing the battery drain drastically in real time 88..87..86 and dis ain’t funny. Also speakers are very low after the update.I bought d phone brand new about 2 months ago. Battery health 💯 %.

I have excatly the same story. Horrible battery life overheating when doing simple things started just after 14.5 update and still its there after 14.6 14.7 and 14.7.1. Something is seriously flawed but apple still does not acknowledge

Same for me. Lost over 15% last night. Usually maybe 7%. Going to look into uninstalling this update. It’s just not good. I think my speaker volume is low too now that I come to think about it. Had difficulties listening to FB video yesterday.
