iPhone 8 and 16.7.1

After running the update on my iphone 8 (you can take a few minutes to laugh about this...), my battery goes dead very quickly. For example, I was a 77% battery and I googled with Chrome for 3 minutes. My battery went to 10%.

My battery was recently replaced at is at 100%. It charges very quickly.

I have disabled all background processes, location services and local activites in google apps.

Other than buy a new phone, any suggestions. Apple - please let me roll back to the last version!!!
