Battery life iPhone 13
After last update to IOS 17.1.1
my battery life reduced to 98%
but my phone is 1 months old, this is a joke 😂 usually it’s can happen after 3-5 months of using the phone but not after the first month.

iOS updates generally aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. Battery health issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.
This seems purely coincidental so please check the Setting on your device. Refer to this discussion thread --> iOS Battery drain - Apple Community
