IOS 13.2 Severe Battery drain when i-messaging

I did the latest IOS update(13.2) on October 31 in the evening. On Friday, November 1, I noticed rapid battery drain when texting with friends. I would send a text message and battery level would drop by 4%. In the space of one hour, battery went from 90% to 28% just through text messaging! This happened again Saturday and again today on Sunday, November 3. I have closed off Location Services, Background Refresh, etc. but no matter what, battery continues to drain rapidly. I contacted Apple Support and apparently, I am not alone - lots of users having the same issue. Apple Care took control of my phone; the battery is in good working order - definitely not a hardware issue but software issue. I have instructed all of my friends to NOT update to IOS 13.2. Apple had better get the technicians working on this issue sooner than later; this is not acceptable!
