Battery health decreased

battery health of my phone goes down 2% within 7-8 days after updating to 16.0!! Why is this happening after new update? Even the the battery timing is also going down fast than usual. What is wrong with 16.0?


iPhone 13 Pro Max, iOS 16

Typically, when upgrading to a new version of iOS, there is a number of background process that will need to take place. These could occur during the first 24-48 hours after upgrading and do take additional activities that will consume more battery. However, these should subside after that time period.


Regardless, Apple does not consider that an iPhone battery requires replacement unless it cannot maintain, at least, an 80% charge after 500 full recharging cycles.
