iPhone 11 (iOS 16) battery drain issue

With update to iOS 16, my (3 year old), iPhone 11 battery was draining so fast, I was making appointments to get a new battery and planning to purchase a new phone in worst case scenario…. However, once I updated to iOS 16.6, a few days ago, the battery drain issue seems to be resolved or at least slowed down significantly, as my battery is now lasting most of the day like it used to and overall phone performance is much improved. Point being, update to iOS 16.6 and hopefully that helps the battery issue like it did for me. 🤓
