18 Pro max battery drain and issues

18 Pro max battery keeps draining.

I had issues with face id and phone automatically switching off two days after I got the phone so I updated the IOS. However after the update, the battery drains faster than usual and i need to keep charging my phone. And the keyboard sound and haptics randomly changed and sounds really strange for a couple of days and i had to restart yet again to get the normal sound. Is anyone else having the same issue?

The measure of battery health deterioration/drainage is subjective and can vary depending on individual usage patterns. 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.
