Same issue after 14.4.2 upgrade. iPhone SE second gen. horrible battery drain issue after the iOS upgrade. Please fix is urgently

It’s been 2-weeks since we are suffering with this issue and still no acknowledgement from Apple- it’s a shame. my iPhone SE second gen is less than 6 month old and this issue was totally unexpected. I don’t have location services or background app refresh going on either. Not to mention my family is laughing at me that I decided to pay twice to buy an IPhone over an android phone which at least gives better battery life/ lower drainage. Will my humble request to Apple to acknowledge and fix this be a waste of my time and words?
