battery in ios 16.6 is draining a lot

The measure of battery health deterioration/drainage is subjective and can vary depending on individual usage patterns and not iOS version updates. There is no universal standard to determine whether the battery health deterioration/drainage is normal or abnormal because it heavily relies on how the battery is used and maintained.

Me too. I got a moto g for ten dollars a few days back that I’m waiting on, supposed to have 2-3 days battery life. I’m done with Apple. My iPhone was perfect and with one update it basically killed the entire battery. It’s Apple so it’s most likely on purpose.

16.6 update has made my battery drain way too fast. Any way to fix it or to go back to previous iOS

Absurd answer. It is all over the internet and your answer is just from textbooks.

I have changed nothing in how I use my iPhone. Prior to the upgrade my battery went no lower than 50% by the end of the day, now it is at 10% by noon and I have to recharge twice a day and all night.
